Green planting method of selenium-enriched corn for brewing selenium-enriched wine

Abstract

The invention discloses a green and organic planting method for selenium-rich corn for selenium-rich wine brewing. The green and organic planting method includes placing preferably-selected corn seeds into an organic selenium solution for soaking for 6-12h, wherein the organic selenium solution needs to brim over the surface of the corn seeds; fishing out the corn seeds after soaking is completed for draining and ventilating to help the corn seeds in aerobic respiration, and timely seeding next day; seeding according to a conventional method, applying 100kg of organic selenium fertilizer per mu as base fertilizer in the process of seeding, and performing effective management according to a conventional management method after seeding is completed; spraying leaves of the corn by adopting the organic selenium solution according to an interval of 20-25 days and spraying quantity per mu of 10-12kg, enabling absorption, of the corn, on selenium element to be maintained at an optimal absorbing rate through three times of spraying, and acquiring the selenium-rich corn after the corn is mature and reaped. Organic selenium in the corn cultivated by the method is easy for human bodies to absorb, and the selenium-rich corn has the advantages of being safe to eat and high in biotransformation rate.

Description

Technical field: [0001] The invention relates to the technical field of planting, in particular to a green planting method of selenium-enriched corn used for brewing selenium-enriched wine. Background technique: [0002] Selenium is an essential trace element for the human body, which has biological properties such as anti-cancer, anti-aging, improving human immunity, and antagonizing heavy metals. Selenium in the food chain mainly comes from soil. If the distribution of selenium content in soil in different regions is uneven, it is an important direction for agricultural production research to implement and carry out targeted selenium-enrichment work based on local selenium-poor soil clues. Optimizing the selenium content level in the food chain is an important direction for agricultural production research. There are 72% counties (cities) in my country with low selenium or selenium deficiency, Keshan disease and Kaschin-Beck disease occur in serious selenium deficient are...

Problems solved by technology

[0004] Most of the existing high-selenium crop cultivation methods utilize the technology of spraying sodium selenite on the page. The biggest shortcoming of this technology is that the residue of inorganic selenium is large, and the spraying technology of high concentration will cause certain damage to the plants. Improper control has the risk of burning seedlings, and too many spraying times result in poor utilization efficiency; on the other hand, the existing methods are only for a certain variety of high-selenium crop field management methods, and are only limited to conventional water and fertilizer management. How to improve the selenium utilization rate, how to ensure the uniformity of the selenium content of the high-selenium crops cultivated and the method of maximally developing the selenium-rich potential of crops have not been reported yet.
