Chinese yam high-yield culture method

Abstract

The invention relates to a Chinese yam high-yield culture method, and belongs to the technical field of crop culture. The method includes the following steps of firstly, selecting a land; secondly, preparing seeds; thirdly, preparing the land and applying fertilizer; fourthly, sowing the seeds; fifthly, arranging ridges and ditches; sixthly, erecting a frame; seventhly, conducting deep intertilling; eighthly, conducting topdressing; ninthly, preventing and treating diseases and insect pests; tenthly, conducting harvesting. The growth habits of Chinese yam serve as the basis, the Chinese yam culture method is scientifically formulated, the diseases and insect pests are prevented in the initial stage of planting, the fertilizer is sufficient in nutrient, it is ensured that seedlings can emerge neatly in time after Chinese yam seeds are sown, the number of fertilizer applying times is small, yield is high, quality is excellent, taste is extremely good, the medicinal healthcare value is high, and economic benefits are high.

Description

technical field [0001] The invention relates to a high-yield cultivation method of Chinese yam, belonging to the technical field of crop cultivation. Background technique [0002] Yam, also known as yam, native potato, yam, Huai yam, Huaishan, and white yam, is a herbal medicine recorded in "Chinese Materia Medica", and its medicinal source is the dried rhizome of yam, a plant of the family Dioscoreae. Yam has the effects of nourishing and strengthening, aiding digestion, suppressing sweating due to deficiency, and stopping diarrhea; it is mainly used to treat diarrhea due to spleen deficiency, cough due to lung deficiency, diabetes and thirst, short and frequent urination, nocturnal emission, women's leukorrhagia and chronic enteritis of indigestion. Yam is rich in nutrition. Every 100g of yam contains about 75g of water, 14.4-19.9g of carbohydrates, 1.5-2.2g of protein, 0.1-0.2g of fat, 50ug of dioscin and B vitamins, vitamin C, and vitamin E. The carbohydrates are mainly ...

AI Technical Summary

Problems solved by technology

In the practice of yam production, we found that the advantage of this process is that the raised ridges are beautiful and good-looking, and the integrity of the ridges is well maintained when it encounters spring rains. The soil heats up slowly, the soil temperature is low, the emergence of seedlings is slow, and it is labor-intensive and time-consuming;

[0007] 4. In the production of yam, there are serious blind fertilization and excessive fertilization, resulting in high investment and low return;

[0008] 5. In the traditional yam cultivation method, the height of the yam shelf is generally 30-50cm, single row and single shelf, herringbone-shaped angle adjustment and crossing, the vines of the yam are coiled and overlapped on the shelf, covering each other, the yam leaves on the surface are fully illuminated, but the inside and bottom The serious lack of light on the leaves of yam significantly affected the photosynthesis of the aboveground part of yam;

[0009] 6. The traditional trenching technology is to use mechanical single drill to open the trench. The drilling speed is generally 300 rpm.
