Selenium enriched-mauve jade Chinese yam planting method

Abstract

The invention provides a double-rowed crossed selenium enriched-mauve jade Chinese yam planting method comprising the following steps of selecting a land, flattening the land, applying fertilizers, placing guide grooves, selecting seeds and processing, retaining water and shielding sunlight, managing the field, preventing disease and insects and harvesting. The Chinese yam seed are processed in a segmental way, so corrosion of the seed segment can be avoided; germination can be accelerated and geminating efficiency can be improved; the length of each seed segment can be shortened, so Chinese yam use amount during the plantation can be reduced; the excessive growth of the Chinese yam cirrus can be prevented, so organic substance complexed by photosynthesis and nutrition absorbed by the yam root can be applied to Chinese yam growth; and output can be greatly improved. A double-row crossed planting method is employed and plantation amount for each mu can be increased compared with the prior single-row plantation method; the selenium enriched land is selected and selenium-containing fertilizers are applied in each fertilizer management, so enough selenium can be absorbed and utilized during the whole growth process of the Chinese yams; and the mauve jade Chinese yams produced by the method is enriched with selenium elements.

Description

【Technical field】 [0001] The invention belongs to the technical field of crop planting, and in particular relates to a planting method of selenium-enriched purple jade yam. 【Background technique】 [0002] Selenium is an indispensable element for the human body. The selenium in the human body is mainly obtained from the daily diet. Therefore, the content of selenium in food directly affects people's daily selenium intake. my country is a selenium-deficient country. There are 22 provinces and regions lacking selenium, and 72% of the population lives in selenium-deficient areas, which require scientific supplementation of selenium. Guangxi is a large selenium-rich province and a large agricultural province. It is uniquely endowed with the development of selenium-rich agricultural products. According to the survey and measurement of the four regions of Nanning, Qinzhou, Beihai, and Guigang by the Guangxi Geology and Mining Department, the area of ​​selenium-rich soil is 31.81 m...

Problems solved by technology

[0004] The existing selenium-enriched purple jade yam planting has begun to adopt a large number of shallow trough directional cultivation techniques, which solves the problem of low yield, curved and bifurcated tubers, uneven tuber sizes, poor appearance, and labor-intensive harvesting in traditional planting techniques. Disadvantages such as large size, 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.
