Guanyinlian
Also known as black-leaf taro and black-leaf Guanyin lotus, they are foliage plants of Araceae. Guanyin lotus is a perennial herb with fleshy tubers in the underground part, which is easy to tiller and form clumps, with a plant height of 30-50 cm. The leaves are arrow-shaped, shield-shaped, 25-40 cm long and 10-20 cm wide, with a sharp top; Petiole longer, lateral veins reaching notch; Dark green leaves with metallic luster, silvery white veins and purple-brown back. Petiole is light green, purple-brown near the stem end, and obvious leaf sheath is formed in the stem. The flower is a Buddha's flame inflorescence, drawn from the stem end, white. Its ecological habit is warm, humid and semi-cloudy, with the optimum growth temperature of 20-30℃ and the overwintering temperature of 65438 05℃. Guanyin lotus is often propagated by ramets. Generally, when the temperature is high in spring and summer every year, the plants with dense tillers in underground tubers are divided along the tuber separation place, so that there are 2-3 plants in each part, and then planted in pots respectively. When dividing plants, the roots should be damaged as little as possible, and at the same time, the pot should be placed in a humid environment, and the soil in the pot should be kept moist frequently, and foliar spraying should be paid attention to, so as to facilitate the new plants to resume growth. You can also dig out underground tubers before germination in spring, cut them into sections and separate them, disinfect the wound with plant ash or sulfur powder, wrap them with moss after drying slightly, or put them in ventilated and drained loose soil to make them grow adventitious roots and sprout new buds. The substrate here should not be too wet to avoid tuber rot. This plant can also be propagated by sowing, but seeds are not easy to get. Guanyin lotus should be potted in loose soil with good drainage and ventilation and rich humus. Generally, humus soil, garden soil and river sand can be mixed in equal amounts as matrix. April-September is its vigorous growth period. At this time, the soil is required to be moist, the air humidity is high, and sufficient water should be given; Especially in the high temperature period in summer, the leaf water evaporation is large and the water demand is more. If the leaves are short of water, they will wilt easily, so water should be sprayed on the leaves frequently and the environment should be kept moist at the same time, but water in the basin must be avoided, otherwise it will cause root rot. When the temperature is lower than 15℃ in autumn, the growth of Guanyin lotus stagnates and becomes fleshy (Figure 2).
In the dormant state, the leaves above the ground began to wither gradually. At this time, it is necessary to reduce the amount of watering as much as possible, put it in a warm and windless dry place, and keep the basin soil properly dry (only slightly wet) for safe wintering; If the humidity is high and the temperature is low, the tuber will rot easily. Guanyin lotus likes semi-shade, avoiding strong light. In a semi-cloudy environment, the leaves are fresh and shiny, the veins are clear and the color is dark green. If the light is too strong, it is easy to darken the leaves, resulting in sunburn, rough leaves, dark leaves, blurred veins, and sometimes burning spots on the leaves; However, too weak light can easily lead to vain growth, and plants grow slender and prone to lodging. In the vigorous growth period, according to the plant growth situation, dilute liquid fertilizer 1-2 times a month can be applied, and phosphorus and potassium fertilizer can be added, which is beneficial to the upright stem and robust growth of the plant, and is also beneficial to the growth and enrichment of the first tuber and the cold resistance in winter.
Carnivorous Guanyin lotus
Scientific name: Sempervivum tectorum alias: evergreen grass, Guanyin lotus, Guanyin lotus and Foliaceae: evergreen grass of Sedum family, also known as Guanyin lotus, Guanyin lotus and Folian, is a small succulent plant mainly for leaf viewing, and it is also one of the succulent plants with relatively large sales in recent years. Its plant shape is dignified, like a blooming lotus, with changeable leaf color and very unique purple tip. Suitable for small and medium-sized potted plants or combined potted plants. Planting with flowerpots of different shapes has different ornamental effects. Planting cartoon flower pots is lively and lovely, which is very popular with children. Planting with purple sand pots or blue and white porcelain pots is dignified and generous, and is favored by middle-aged and elderly people; There is also Guanyin lotus planted on succulent wood (Figure 3).
Small flowerpots are fashionable and natural, and are very popular with young people. Evergreen grass is a perennial succulent plant, belonging to Sedum evergreen, with rosette-shaped leaves and many varieties, with diameters ranging from 3 cm to 15 cm. The fleshy leaves are spoon-shaped and sharp at the top. The colors of leaves are grayish green, dark green, yellow-green, reddish brown, and the tips of leaves are also green, red or purple. At present, they are very popular in the market. A well-developed plant will plant a small rosette under the big rosette. In addition, every year at the end of spring, a red walking stalk similar to chlorophytum will be drawn from the lower part of the leaf, and a small rosette will grow at the front end of the walking stalk. The small flowers of perennial grass are star-shaped and pink.
Edit the growing environment of this part.
Guanyin Lotus (Figure 3)
Guanyin grassland is produced in the mountainous areas of Spain, France, Italy and other European countries, and likes sunny, cool and dry environment. It is an alpine succulent plant. When it is hot in summer and cold in winter, this plant is dormant. The main growing season is in cool spring and autumn, and the growing season needs plenty of sunshine. Insufficient light will lead to loose and compact plant shape, which will affect its ornamental value. Plants growing in sunny places have plump leaves and compact plant shapes. When watering, you should master the principle of "don't dry it, but water it thoroughly" to avoid the accumulation of water for too long, so as not to cause root rot, but it should not be too dry, otherwise the plant will not die, but will grow slowly, its leaves will be dim and lack vitality. Apply decomposed dilute liquid fertilizer or low nitrogen, high phosphorus and potassium compound fertilizer every 20 days or so. In winter, the temperature shall not be lower than 5℃ at night and 15℃ during the day. Plants can continue to grow, and they can be watered normally and fertilized properly. If watering is controlled to make plants dormant, they can also withstand the low temperature of 0℃.

Growth characteristics
Guanyinlian is a perennial herb belonging to the genus Guanyinlian in Araceae, with thick stems, large papery leaves and wide arrow-shaped leaves, which are widely distributed in humid woodland in southern China. Its plants are tall and straight, its leaves are green and bright, and its adaptability is strong. In recent years, it has been widely cultivated as an indoor ornamental plant and is deeply loved by breeders. There are also some ornamental varieties that coexist with it and are often cultivated, such as Lou's Guanyin lotus and taro. Guanyin lotus likes high temperature and humid semi-cloudy environment, and is afraid of the scorching sun in summer. It does not require much soil, but the fertile Ryukyu pine sand is conducive to tuber growth and hypertrophy. Generally, fertile garden soil can be used when potted. Guanyin lotus culture is easy to succeed. In the growing season, except June-September, half-day illumination is appropriate at other times. If it is placed indoors, it should be placed near the south-facing window. After being placed indoors for 1 month, it should be moved to a damp place under the shed for curing for a period of time. Water the soil often to keep it moist, but at the same time, prevent excessive water or water accumulation in the basin, otherwise it will cause root rot. Therefore, it is necessary to lay a layer of coarse sand at the bottom of the basin as a drainage layer to strengthen the drainage function. When drying at high temperature, it is necessary to spray water and humidify it to obtain the external conditions for vigorous growth. Fertilize 2-3 times a month during the growing season. Water should be reduced after entering the room in winter, and the temperature should not be lower than 5℃.
breeding method
[ 1]? The propagation of Guanyin lotus is mainly carried out in May and June. When two leaves are extracted from the tuber, they can be separated, and the cut wound should be coated with charcoal powder. It is best to expose the cultivated soil to hot sun or steam and disinfect it a few days in advance. After planting and emergence, spray to keep the leaves moist, and put them in the shade for a transitional period before moving to semi-shade. In addition, when the temperature reaches 20℃ or slightly higher, you can also sow with small tubers. The top of the small tuber is facing up and buried in the sterilized substrate. The substrate keeps moderate humidity, and generally new buds can grow in about 20 days. If it is necessary to expand reproduction, the tuber can be divided, but the wound should be disinfected with sulfur powder. Plant when the temperature is slightly lower to prevent rot. Guanyin lotus is often propagated by ramets. Generally, when the temperature is high in spring and summer every year, the plants with dense tillers in underground tubers are divided along the tuber separation place, so that there are 2-3 plants in each part, and then planted in pots respectively. When dividing plants, the roots should be damaged as little as possible, and at the same time, the pot should be placed in a humid environment, and the soil in the pot should be kept moist frequently, and foliar spraying should be paid attention to, so as to facilitate the new plants to resume growth. You can also dig out underground tubers before germination in spring, cut them into sections and separate them, disinfect the wound with plant ash or sulfur powder, wrap them with moss after drying slightly, or put them in ventilated and drained loose soil to make them grow adventitious roots and sprout new buds. The substrate here should not be too wet to avoid tuber rot. This plant can also be propagated by sowing, but seeds are not easy to get. Guanyin lotus can also be propagated by tissue culture seedlings. After purchasing the seedlings, before planting, disinfect the seedlings with 1500-2000 times chlorothalonil. After preparing the liquid medicine, soak the whole seedling for disinfection. Planting time 4? May is suitable, and the temperature should be kept above 20-25℃, which is beneficial to seedling growth. Water every 2 to 3 days after planting to keep the soil moist. Don't water too much, lest the roots rot.
Key points of management
First, the seed ball pretreatment technology before planting, the seed ball should be stored in a ventilated place at room temperature of 265438 0℃ for two weeks, and the temperature should be kept stable. If it is not planted within two weeks, it should be stored at a stable temperature of 12- 15℃ to adjust the planting time. If long-term storage is needed, it should be stored at a stable temperature of 8℃. Before planting, all stored bulbs should be domesticated at 265438 0℃ for 2 weeks. In order to prevent bulbs from being invaded and infected by bacteria and fungi, preparatory measures before planting are necessary. Care should be taken to avoid damaging the seed balls when handling or touching them. Before planting, if unhealthy bulbs or bulbs infected with mold or soft rot are found, they must be removed and destroyed. According to the research, GA _ 3 can prevent the seeds from sprouting during storage and promote the transformation from vegetative buds to flower buds. In addition, when the main stem buds are ineffective or germinate, GA3 can induce the lateral buds to blossom. Another experiment proved that GA3 can promote early flowering, increase the regularity of flowering and increase the number of flowers (especially for golden yellow), but the treatment concentration should not be too high, otherwise abnormal flowers will easily appear. For example, an annual ball with a diameter of 2 cm, soaked in GA3, can promote flowering, and it will not bloom without soaking. The bigger the seed ball, the more flowers, and the better the flowering uniformity. Generally, the treatment method of GA3 is to soak seeds in 50ppm for 30 minutes a few days before sowing, and then dry them in the shade. Spraying GA3 on leaves after planting is also beneficial, but the effect of this treatment is worse than that of soaking seeds before planting, and the flowers are irregular. Promalin (-GA4, GA7 and BAP), like GA3, can promote early flowering, improve flowering uniformity and triple the number of flowers, but the concentration varies with varieties. Generally, seeds are soaked in 3ml/l(50ppm) for 30 minutes, and then dried in the shade. It is very important to disinfect the seed balls before sowing. The method is to soak the seed ball with 200 times streptomycin for 30 minutes, then put it in the shade to dry overnight, and then plant it. This sterilization treatment can be carried out while soaking the seeds with GA3, that is, mixing them with GA3. According to the research, GA3 can promote the flowering of colored Guanyin lotus in advance, increase the flowering regularity, that is, promote the transformation from vegetative buds to flower buds. In addition, when the main stem buds are ineffective or blind, GA3 can induce the lateral buds to bloom and increase the number of flowers. However, the treatment concentration should not be too high, otherwise deformed flowers will easily appear. Second, planting and cultivation management Different varieties of Guanyin lotus need different cultivation methods. During the cultivation period, we should always pay attention to observation and give the most suitable environmental adjustment and fertilizer nutrients and water to maintain the vigorous vitality of plants. At present, the most widely cultivated and popular Golden Guanyin Lotus is generally imported from New Zealand. If it is not planted immediately, it must be placed in a ventilated planting box and stored in a refrigerator at 8- 10℃. Planting density varies with tuber size. For example, the diameter is 4 cm, the row spacing is 20 cm (about 5000-6000 bulbs are planted in each plot), the planting depth is 10cm, and the bulbs are covered with soil or substrate for about 2-3 cm. Irrigation and drainage shall be carried out immediately after planting. After the first planting, the bulbs should be fully watered once to combine with the soil, and then a small amount of water should be supplied several times, but not too wet. The soil in the planting area should be well drained, with poor water retention and slightly acidic pH of 6.5. Organic compost should be applied before planting, and foliar fertilization is better during the growing period. Liquid fertilizer of 20-8.7-/kloc-0,500 ppm should be applied every 7-1 6.6 or 27-6.5-/kloc-0. It is very important to cultivate colorful Guanyin lotus and observe it in the field every day. How to avoid overgrown weeds, do a good job in pest control and control the moisture of soil or medium are all important field management work from planting to painting flowers and collecting bulbs. There are many colors of colored Guanyin lotus, which vary greatly. Generally, it is easy to distinguish the differences between varieties only at the flowering stage, so how to avoid variety mixing is one of the important topics of cultivation management. It is best not to plant many varieties in the same field, but only plant one variety, which can avoid the mixed varieties after the ball is collected. Third, the cultivation of colored Guanyin lotus in soilless medium can also be cultivated in soilless medium, and colored Guanyin lotus can be cultivated in different media. The media type is1:1made of sphagnum, vermiculite and nacrite, and there is also bark compost. If it is pure bark, it is too dry to retain moisture, and sphagnum can be added. If it is pure sphagnum, it is easy to retain water. When cultured in a culture medium, it needs to be easily set up. The tubular planting bed adopts a low bed, with a bed width of 60-70cm and a bed height of 15cm, with 50cm walkways between the planting beds. Each bed is filled with a culture medium with a height of about 10 cm, and Guanyin lotus seeds are planted at the bottom of the culture medium, and the culture medium covers it for about 5 cm. After planting, the substrate needs to be completely wetted, so that the bulbs can combine with the substrate and promote the early germination of the bulbs. It is necessary to spray water once a week in the future. The colored Guanyin lotus should not be too wet, as long as it keeps proper humidity. If the culture medium is too wet or the temperature is higher than 23℃, it will easily lead to soft rot. 4. Flowering and post-harvest treatment: The best time for picking flowers is from 3/4 unfolding of the spathe to full unfolding, when the pollen on the inflorescence has not yet spread. Usually, the pollen is scattered about 4-7 days after the bracts are unfolded. Cut flowers are usually picked in the early morning or in the cool evening. There are two harvesting methods. One is the pulling method, which has a long pedicel, but it is easy to hurt the stem and easily lead to the injury of the root and infection with soft rot fungi. The other is the shear type, the pedicel is about 8 cm shorter than the pull-out type, but it can reduce disease infection. After harvesting in the field, it should be put into a bucket to absorb water immediately, and then sent to the grading and packaging room for grading and bundling. Proper grading is an important link in quality control and an important factor affecting the price of cut flowers. The shape, color, pedicel length and thickness of flowers are the basis of classification. After classification, soak it in fresh-keeping liquid to absorb water for 3-4 hours (the water absorption rate has reached 80% in the first 2 hours), and then move it into a refrigerator at 6-8℃ until it is packed and shipped. 5. Harvest and treatment of bulbs: The harvesting and treatment technology of bulbs can affect the quantity and quality of cut flowers in the next season. Usually, the leaves of colored Guanyin lotus begin to turn yellow more than two months after flowering (about 120 days after planting), and seed bulbs can be harvested. If the seed ball is harvested too early, it is easy to be injured and difficult to handle because it is still developing and hypertrophy, with high water content. The method of digging the seed ball can be mechanical or manual, but it is easier to hurt the seed ball with machinery. It is best to wait for the bulb to dry before removing the absorption root system of colored Guanyin lotus, so as not to hurt the bulb. If the surface of the seed ball is mixed with soil or other impurities, it can be blown clean with high-pressure air or brushed with a brush, and it is best not to wash it with water to avoid breeding soft rot. If the seed ball is wet, it should be dried immediately within 12~24 hours. After air-drying the dug seed balls for 3-7 days, they are packaged and stored in different grades according to the size of the seed balls. The general storage temperature is 12- 15℃, and it takes at least 10 weeks to break dormancy. For long-term storage, the storage temperature should be slightly lower than 8- 10℃, and the air in the refrigerator should be convective.
