Snow lotus fruit fructooligosaccharides content is 60-70% of the dry matter, its content is the highest of all plants, but also rich in minerals and calcium, magnesium, iron, zinc, potassium, selenium and other trace elements. Japanese research and found that taking 3-6g of fructooligosaccharides per day, within 3 weeks, the content of toxic carcinogenic compounds in human feces can be reduced by more than 40%. Snow lotus fruit carbohydrates are rarely absorbed by the body, so it is very suitable for diabetics and dieters to eat. Fructooligosaccharides have the following properties: ① Into the digestive, regulating the gastrointestinal tract; ② is the intestinal beneficial bacterial clusters of the promoter, the production of bifidus factor; ③ regulation of blood, remove high blood fat, effective control of cholesterol and diabetes; ④ laxative, prevention and treatment of dysentery; ⑤ lowering the fire and clearing the toxin, prevention and treatment of blisters, acne; ⑥ improve immunity.
Negative effects: cold nature, people with bad stomach and intestines should eat with caution. After a large amount of consumption will appear stomach cold, stool soup and other symptoms.
It should be noted that the snowdrop fruit contains a chemical component - tannin, also known as tannin. After the fruit is cut and peeled, it turns brown when exposed to air. The discoloration is due to oxidation, where the phenols in the tannins produce polymers of quinone to form brown pigment, also known as melanin. In order to prevent discoloration, you can put the peeled and cut snowdrop fruit in water to soak, so that it is isolated from the air, can prevent oxidation discoloration.
The medicinal value and health benefits of snowdrop fruit
1, regulating blood, can reduce blood sugar, blood fat and cholesterol, can prevent and treat hypertension, diabetes, cardiovascular disease and obesity, etc. Also has a certain effect. 2, help digestion, regulate and improve the digestive system. Because of the snow lotus fruit is rich in water-soluble dietary fiber and all plants with the highest content of fructooligosaccharides, so it can significantly promote gastrointestinal peristalsis, laxative, not only to eliminate constipation, but also to prevent and control dysentery, is the nemesis of gastrointestinal tract diseases. The most wonderful thing is that it is the proliferation factor of double-aggressive bacteria in the intestines, to overcome the life rhythm of tension, excessive use of antibiotics and other reasons caused by double-aggressive bacilli and other intestinal bacteria to reduce the imbalance caused by systemic diseases, can be clear by the food to bring everyone in the body of environmental pollutants, is the gastrointestinal scavenger and the God of protection.
3, can antioxidant, eliminate free radicals, can reduce or avoid the occurrence of stone disease.

Snow lotus fruit is the new trend of eating beautiful fruit. Snow lotus fruit is a rare crop out of nowhere, it appears, declaring the beginning of a new era of health fruit, it will be in 10 years will always be in short supply. It can make growers rich and users strong and healthy. [Edit Paragraph] Cultivation Snow The whole lotus fruit has been planted in many countries around the world, with different names in different countries. After the introduction of China there are also several names, such as snow lotus fruit, chrysanthemum potato, snow lotus potato, ground ginseng fruit, Yagong Jaigong, etc.. Among them, Yagong, Yagong called, may be derived from the local name yacon translation. The snow lotus fruit belongs to the family Asteraceae, using part of the form of potatoes, we believe that the scientific name is called "chrysanthemum potato" is more appropriate, and will be categorized as yams and taro vegetables.
In 1985, Japan's Saitama County introduced successful, in recent years through a variety of ways to enter our country, has been in Yunnan, Fujian, Hainan, Guizhou, Hunan, Hubei, Shandong, Henan, Hebei, introduced successful cultivation. The production demonstration area is more than 96 hectares. Products are mostly used for export, part of the supermarket. [Edit this paragraph] cultivation technology a, land preparation and ridging: choose convenient drainage and irrigation of sandy loam best land, per mu 2000-3000 kg of farmyard manure, spread evenly after deep plowing, do not apply chemical fertilizers, and do not play pesticides, using row spacing of 1 m, spacing of 0.6 m, planting 1111 per mu, planting before the ditching of ridging, will be planted in the back of the ridge of the snowdrop fruit seeds, in order to prevent Underground pests, can be applied to the planting hole in the appropriate amount of quicklime for prevention.
Two, planting: planting period varies from place to place, generally in the spring when the 5 cm ground temperature stabilized at 14-15 ℃ can be planted, protected cultivation can be planted ahead of time, planting can be planted directly in the field of seed blocks, can also be used to nutrient pots or nutrient bags in the greenhouse seedlings and then planted in the field, the summer can be cuttings cuttings of the branching and the underground sprouting side branches.
Three, management: after planting when the seedling height of 20 cm should be watered to maintain moisture, and combined with weeding, the plant to cultivate the soil, such as planting before the amount of fertilizer is insufficient, this period should be again appropriate amount of soil fertilizer to supplement the attention of not to apply chemical fertilizers, pesticides and herbicides, the soil drought should be watered, the rain should be drained in a timely manner, when the stem grows to 1 meter or so, it will be at the base of the tillers, such as the growth of exuberant caused by the field of depression! Can break off the tiller branches, the growth of the average can be appropriate to choose to stay 1-2 tiller growth, in order to expand the propagation, the break off the tiller branches can be used as propagation material for cuttings, growth to the late fall there will be a large number of seedballs to harvest.
Four, fruit harvest: around October, the plant stem tip of the bunch of flowers began to wither, the leaves began to yellow that is the beginning of the digging fruit, the South can stay in the ground over winter, digging at any time to sell, the North should be dug before the frost into the cellar storage, as if sweet potatoes to save, the stem can be made of high-quality fodder, the leaves and flowers have a very high nutritive value, can be dried and brewed tea or processed for reuse, the general production of 3 kilograms per plant. General production of 3 kilograms of fruit per plant, the highest yield of 10 kilograms, mu yield of 3000-4000 kilograms.
Five, stay seed: snow lotus fruit excavation, the fruit of the upper seed ball cut off, the wound cool dry, with 100 times the potassium permanganate solution soaked for 3 minutes, fish out with wet sand buried in the cellar or frost-free indoor, the next spring can be used for seed.
The snowdrop fruit mulching and seedling transplantation technology
In order to obtain the snowdrop fruit quality and high yield, the use of mulching and seedling transplantation technology, early sowing and seedling, prolonging the growth period of the plant, increase the time of illumination, enhance photosynthesis, and maintain the soil temperature and humidity, in order to improve the yield and quality of the snowdrop fruit, it is an effective and powerful measure.
Mulching technology:
First of all, as we have previously elaborated, adequate bottom fertilizer pouring good bottom moisture water, plowing and harrowing, according to the row spacing of 85-100 cm planning, with a small four-wheeled tractor with a 1.2 m to 1.3 m of the border machine, scraping the soil to hit the border, the ridge height of 20-25 cm, and then artificially straighten up the shape of the fish spine, there is no machinery, you can manually scrape the soil to hit the border to start the ridge. Then manually organize the ridges in the shape of fish ridge. After the ground is made up, mulching time is mastered in the local early spring before the frost break about ten days, choose the warm head and cold tail, no wind and sunny days, covered with 70 ~ 80 cm of film, if you want to engage in early spring planting of watermelon, melon and other crops, you can choose to use 1.2 m to 1.3 m of film, the conditions of the available four-wheeled tractor-mounted mulching machine mulching, there are no conditions of the artificial mulching is also OK, need 6 to 8 people working in a stream, that is, the front side of the Two people to open the ditch (5 cm or so), two people put the film, two people behind the mulch film, the last two people second mulch compaction, to prevent the wind from blowing up the film, fewer people can be divided into sub-operations. After covering the film, according to the appropriate spacing 45 ~ 60 cm, eyeballing the seed or digging holes to plant seedlings, pay attention to cover the film holes with soil, but also can be planted first after covering the film, so that the effect of moisturizing and heat preservation is better.
Nursery transplantation technology:
Advance one and a half months according to the transplantation time under the seed nursery. Spring ground transplanting seedlings, can start at the end of February and early March, the use of greenhouse greenhouse or ordinary room heating can be. Seedlings and nutrient bowl seedling and hotbed block seedling two kinds. Nutrient bowl seedlings, the first preparation of nutrient soil, fertile and disease-free soil with a small amount of rotting fertilizer is best. Mastery of humidity 50% or so, hand held into a ball, fall to the ground on the scattered appropriate, and then loaded into the 6 to 8 cm nutrient bowl, a single bud under the seed (seeds first sterilized with carbendazim), sprinkled with soil to cover the buds after the eye, with a sprayer to spray water wet. Control the temperature about 25 ℃, the lowest can not be lower than 15%, high do not exceed 35 ℃, usually about 10 days germination and seedling. Usually strengthen the observation and management, to be transplanted before 10 days of seedling refining and release, after the break of the frost period transplanted to the field, the ground film cover is better. Hotbed block nursery, the first to prepare plastic film, bamboo, grass thatch and other materials, and then digging seedbed. According to the planted area accounting, general mu planting 1500 plants, seedbed 30 square meters can be. Seedbed width of 2 to 3 meters, the length of the number of seedlings according to how much depends on the hotbed soil and nutrient soil as mentioned above, after planting, tied on the bamboo sheet, masked plastic film, cover thatch can be good. However, thatch should be lifted early and late cover, in order to facilitate the absorption of light to increase the temperature. Hotbed seedling germination compared to a few days later, but the seedling strong and not prosperous. Ten days before transplanting the same need to wind refining seedlings. Transplanting with a shovel block seedling, and then gently put, transplanted in a timely manner to the field, whether it is greenhouse nutrient bowl seedling. Whether it is a greenhouse nutrient bowl nursery. Or hotbed paddling block nursery, transplanting field is best to use the film cover (first cover the film after planting seedlings). In order to facilitate heat preservation and moisturizing. After planting seedlings timely watering mulch. Early spring transplanted seedlings, to point hole watering or watering small water, do not large water irrigation.
