Planting method of grapes rich in elemental selenium

Abstract

The invention relates to a planting method of grapes rich in elemental selenium. The planting method of the grapes rich in elemental selenium comprises the following steps of diluting a nano-selenium microbial selenium fertilizer preparation by 15-25 times by using water, and respectively spraying the generated diluents of the nano-selenium microbial selenium fertilizer preparation to roots and leaves of grape vines in a new leaf stage, a fruit setting stage, a fruit growing stage and a stage before fruit picking of the grapes, wherein the content of the selenium element is 20-50mg / kg and is 3-20 times that the content of the selenium in ordinary grapes. Selenium is an essential trace element of the human body; the selenium of the nano-selenium-rich grapes exists in the form of nano-selenium which can be easily absorbed by the human body; the selenium fertilizer preparation is prepared from selenium dioxide or selenium trioxide and salts such as sodium selenite, ammonium selenite and sodium selenate by biological fermentation of various probiotic organisms such as saccharomycetes, lactic acid bacteria and bacillus. The frequency for spraying the selenium preparation to the roots and the leaves is increased, so that the content of selenium of the grapes rich in selenium is also increased by absorbing and converting by the grape vines. The planting method of the grapes rich in elemental selenium is simple to operate and low in cost. The grapes are used as one of good fruits for supplementing selenium to the human body.

Description

technical field [0001] The invention relates to a planting method of monoselenium-rich grapes, belonging to the technical field of agricultural planting. Background technique [0002] my country is a big selenium-deficient country. The census proves that more than 70% of the soil in our country is seriously deficient in selenium, and the selenium content in more than 95% of the grain and livestock and poultry meat in our country is less than 50 μg / kg, which belongs to a large selenium-deficient country. The per capita selenium intake in my country is only about 39 micrograms per day, which is less than 80% of the minimum requirement for adult success of 50 micrograms per day, and is far from the healthy requirement of 100-200 micrograms per day; it is farther away from the safe upper limit of 800 micrograms. In my country, except for a few areas, 90% of the population needs to use bioengineering technology to supplement selenium. Not only people need to supplement selenium...

AI Technical Summary

Problems solved by technology

[0007] The development of selenium-enriched grapes can inject new vitality into the grape industry. There are many kinds of planting and cultivation methods for selenium-enriched grapes, but most of the selenium-enriched grapes are inorganic selenium or organic selenium, inorganic selenium or organic selenium. Selenium has low biological activity and has no antioxidant properties. The human body has a very small absorption rate of inorganic selenium salts or organic selenium. Excessive consumption has certain toxicity to the human body and increases the harm to the human body.
