Method for planting purple Chinese yams

Abstract

The invention provides a method for planting purple Chinese yams in a twin-row crossed staggering mode. The method includes the following steps that soil preparing and soil fertilizing are carried out, guide grooves are placed, seed selection and treatment are conducted, water retention and sunshade treatment is carried out, field management is performed, diseases and insect pests are prevented and treated, and harvesting is achieved. The method has the advantages that the purple Chinese yams planted through the guide grooves are uniform in body shape and weight and excellent in both appearance and color, and the phenomenon that the appearance of delicious Chinese yams is bad is avoided; Chinese yam seed sections are treated, the seed sections cannot rot after being planted, germination is accelerated, the sprouting ratio is increased, and meanwhile the length of each seed section is decreased, so that the purposes of reducing the using quantity of the Chinese yams in the planting process, guaranteeing the germination rate, increasing the planting quantity per mu, increasing the yield and the like are achieved; due to the fact that the twin-row crossed staggering planting method is adopted, compared with an existing single-row planting method, the planting quantity per mu can be obliviously increased, and the yield per mu is greatly increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of crop planting, and in particular relates to a planting method of purple jade and yam. 【Background technique】 [0002] Purple jade yam, also known as purple yam, also known as "purple ginseng", contains a lot of nutrients such as protein, polysaccharides and starch. It has the effects of nourishing the lungs and kidneys, strengthening the spleen and stopping diarrhea, and is delicious. Purple jade yam contains a large amount of purple anthocyanins, 60 times that of white yam, which is beneficial to the treatment of cardiovascular diseases, and has the effect of anti-oxidation and beauty. Regular consumption of purple jade and yam medicine can not only increase the body's resistance, lower blood pressure, blood sugar, anti-aging and prolong life, but also benefit the spleen, lungs, kidneys, etc. King of".

AI Technical Summary

Problems solved by technology

[0003] The existing purple jade yam planting has begun to adopt a large number of directional cultivation techniques in shallow troughs, which solves the problems of low yield, bending and bifurcation of tubers, uneven size of tubers, and poor appearance when harvesting. Disadvantages such as difficulty in digging and easy breakage of Huaishan potato pieces

However, the existing shallow trough directional cultivation technology adopts single-row planting, which leads to a sharp decrease in the planting amount per mu, and the yield per mu is not high; at the same time, in the existing planting technology, the seed section is generally 10-15 cm, and the seed that needs to be used for planting The quantity of yam is large; because there are cuts at both ends of the seed section, it is easy to rot after planting, and the germination rate cannot be guaranteed, etc.
