How to grow green radish? Many people choose to plant green radish when planting plants, but green radish likes warm environment and has poor cold tolerance. Both soil cultivation and hydroponic cultivation are very sensitive to low temperature environment, and it takes skill to cultivate green radish. So how to cultivate green radish?
Radish 1 How to Cultivate 1. Conservation Methods of Soil Culture
1, soil: If you want to cultivate green radish in soil, you should pay attention to the soil used. The soil should be soft, breathable, fertile and acidic. Only in this soil environment can roots germinate better, absorb fertilizer and water, and thrive.
When mixing soil, proper amount of humus and river sand can be mixed into the garden soil. Rotten soil can improve acidity and softness, and river sand can improve drainage capacity. Note that the soil needs to be disinfected before it can be used. Or you can buy special soil for flowers, which is also beneficial to its growth. If the soil is too sticky and alkaline, it is easy for the green radish to grow badly.
2, watering: green radish likes wet environment, but is afraid of waterlogging. If it is watered frequently or excessively during the maintenance period, the green radish can't absorb it, and it is prone to root rot. Too dry soil is not good for growth.
It is suggested that the surface soil should be watered after it is dry, and it is best to water rainwater, well water and river water. Long-term watering with tap water will change the pH of soil and reduce acidity. In this case, ferrous sulfate solution should be poured regularly to improve the acidity of the soil. Green radish also has high requirements for air humidity. If the climate is dry, you can often spray water to improve the humidity.
3, temperature: green radish likes a warm environment, has a slight high temperature resistance, not afraid of cold. If it wants to thrive, it needs good temperature control. The temperature should be kept at 15 ~ 28℃, and the lowest tolerable low temperature is about 5 degrees.
So be sure to move indoors after winter, and the temperature should be controlled above 10℃ to avoid frostbite. Be careful, if there is heating at home, don't put the green radish too close to the heating, otherwise it will be easy to burn. In addition, when the temperature exceeds 30℃ in summer, it is necessary to strengthen ventilation and often sprinkle water to cool down properly.
4, lighting: radish has strong shade tolerance and is afraid of strong light. If you want it to grow vigorously and its branches and leaves are greener, you'd better put it in a bright place and bask in the sun occasionally. Like morning and evening light. It should not be placed in a cool environment for a long time, nor should it be exposed to direct sunlight for a long time, otherwise it will affect growth.
5. Fertilization: The demand for fertilizer for green radish is not large, but if it wants to grow more vigorously, it needs proper topdressing in the peak season. Specifically, topdressing in spring and autumn. Just choose compound fertilizer with more nitrogen as fertilizer. After dilution, the fertilizer solution is poured on the soil surface once every 20 days, and it is poured continuously for two or three times. When the temperature in Xia Dong is too high or too low, fertilization should be stopped to avoid fertilizer damage.
6. Soil replacement: The soil-raised green radish should be replaced regularly, preferably once a year, once a year in spring or autumn, so that the soil is rich in nutrients, not easy to harden, and there is more room for growth, which can promote the green radish to grow more vigorously. When changing soil, it is suggested to combine with root pruning at the same time, pruning to remove rotten roots, old roots and dead roots, so that it can better absorb fertilizer and water in the later stage and is conducive to growth.
Second, the maintenance method of hydroponics
1. water quality: pay attention to the water quality used for radish hydroponics and maintenance. It is best to use rainwater, well water and river water for maintenance. This kind of water is mostly acidic, which is beneficial to its growth. If tap water is used at home, it must be dried before it can be used, and the chlorine inside must be volatilized, otherwise the chlorine is too heavy, and it is easy to have yellow leaves after a long time.
2. Change water: Change water regularly during the water conservation period to ensure clean water quality. It is best to change the water once a day before rooting, and it can be reduced to 10 ~ 15 days after rooting. If turbid water pollution is found, it should be replaced in time. When you find that there is little water, you should replenish it in time.
3, nutrient solution: the water contains less nutrients. If you want to raise the green radish in the water more vigorously, you must drop nutrient solution to ensure sufficient nutrients. The nutrient solution can be a special nutrient solution for hydroponics, or a few drops of compound fertilizer can be dropped in water to improve fertility. Put it after changing water every time, and give it sufficient nutrient supply.
4. Root pruning: the growth rate of green radish is relatively fast, and the root growth of hydroponic culture is relatively fast. When old roots, dead roots, rotten roots or roots are found to be too long, they need to be pruned in time to promote them to better absorb fertilizer and water, so as to flourish.
5, lighting: hydroponic green radish can properly bask in the sun, it is best to see the light for about 3 hours a day. Attention, be sure to block the strong light at noon and only bask in the sun in the morning and evening. In an environment with sufficient light, leaves will perform better photosynthesis, thus accumulating more nutrients and promoting faster and more vigorous growth.
6. Temperature: The green radish originally liked a warm environment, and the cold tolerance of hydroponics was poor. The temperature was too low, and the water was easy to freeze, leading to the death of the green radish. It is suggested that the temperature should be controlled around 65438 05℃, and the minimum temperature should not be lower than 65438 00℃. I usually do indoor activities in late autumn, and the temperature is well controlled in winter. In addition, we should also pay attention to the high temperature in summer, and it is best to move to an air-conditioned room in summer. If the temperature is too high, the temperature of water will also rise, which is not good for the growth of green radish.
How to plant radish 2 1 and cut leaves
Cutting the right leaves is one of the keys to good radish cutting. You can choose a healthy and complete leaf from the mother plant of radish, leave a 3 ~ 4 cm stem under it, and preferably have a taupe root on the rhizome, and then cut it under the root.
2. Leaf treatment
The cut seeds with stems and leaves need to be treated, soaked in rooting powder solution, taken out after 6 hours, and dried in the shade. In this way, branches and leaves soaked in rooting powder solution can grow new roots faster and better.
Step 3 prepare the soil
When cutting radish, you should also prepare loose and drained acidic soil. You can mix perlite and coconut bran soil in equal amounts to form loose and fertile suitable soil. Moreover, a small amount of granular soil can be added to make the soil more breathable and permeable.
Step 4 trim branches and leaves
After getting ready, put the cut radish leaves into the prepared breathable soil. The roots should be directly inserted into the soil, the depth is 2/3 of that of the stems and branches, so that the leaves stand upright in the basin. Then water the soil and soak it, and then cover the leaves with a layer of plastic film to keep warm and moisturize.
5. Rooting and curing
After the leaves are cut into the soil, new roots will grow in about half a month. After that, remove the plastic film on it and put the potted plants in a ventilated place. Then do a good job of watering to make it have light and temperature suitable for normal growth.
6. Matters needing attention
After the radish is cut, it needs to be kept in a dark and ventilated place for the first three days to avoid sunburn. Then slowly increase the light and let it grow normally through photosynthesis. Do not water for the first three days except when planting to prevent the leaves from rotting.
How to cultivate radish 3 1, soil culture and hydroponics
Soil culture: green radish is easy to raise, and the preparation of soil culture is to choose the soil suitable for the growth of green radish. The more fertile the soil, the better. Most of the nutrition of the green radish comes from the soil. Try to choose some soil in the field, mix some animal manure in the soil, and put some fine dead leaves in the soil. Green radish likes soft soil, and dead leaves and feces play a role in increasing soil fertility, softness and ventilation.
Hydroponics: Hydroponics is one of the very good hydroponic plants for indoor decoration, climbing and foliage viewing. Radish stems are thin and soft, and leaves are exquisite and beautiful. Hydroponic radish is extremely shade-tolerant, and can be placed indoors in sunny places all year round. In a dark room, move to a strong light environment for a period of time every half month, otherwise it will grow easily and the leaves will become smaller.
2, light and temperature
Illumination: The original growth condition of green radish is in the forest covered by towering trees, and there is no sunshine. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, the illuminance should be increased.
Temperature: In the north, when the room temperature is above 10℃, the green radish can safely overwinter, and when the room temperature is above 20℃, the green radish can grow normally. It is not a big problem for ordinary families to reach this temperature. It should be noted that the temperature difference is too large, and the leaves should not be close to the heating equipment.
3, water and fertilizer management skills
Watering: The amount of watering in autumn and winter should be strictly controlled according to the room temperature. The temperature before heating is low, and the soil of plants evaporates slowly. Reduce watering, and the water quantity should be controlled between the original 1/4- 1/2. Even after heating, don't pour water too often, and pour less water into the basin. The water should seep through the brown silk.
In addition, water should be sprayed on the aerial roots of the palm column to reduce the insufficient water absorption of the roots caused by too fast evaporation. The water poured in winter is better to bask in the sun for a day, and the water is too cold to damage the roots. When raising water, the amount of water should not be too much, and the roots can be submerged. When there is too much water, the stems and leaves are easy to rot.
Fertilization: In northern autumn and winter, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, liquid inorganic fertilizer is mainly sprayed once every 15 days.
Fertilization is mainly sprayed on the leaves after winter, mainly through the stomata on the leaves, and the fertilizer is absorbed through the stomata on the leaves, so the fertilizer effect can directly act on the leaves. Special fertilizer should be used for foliar fertilizer, and ordinary inorganic fertilizer is not easily absorbed by foliar. The flower protection series of Peking University and the flowers produced in Japan can be used as foliar fertilizer.
4. Breeding methods
Usually, the propagation of green radish adopts cutting method. In late spring and early summer, choose robust Celastrus orbiculatus, cut off branches from 15cm to 30cm, and remove leaves from the base 1 to 2 nodes, taking care not to hurt the air roots.
Then insert it into plain sand or cinder, the depth of which is 1/3 of the cutting depth, drench it with water, place it in the shade, spray water on the leaves every day or cover it with plastic film to moisturize, as long as the environment is not lower than 20℃, the survival rate is above 90%.
5. Common diseases
Common diseases of radish: anthracnose, root rot and leaf spot.
These three common diseases of radish are harmful to the leaves of plants and affect the ornamental value. Be sure to observe carefully during the maintenance process, and clean and spray chemicals in time if you find that the leaves are sick.
