High-yield culture technology of selenium-enriched peanuts

Abstract

The invention discloses a high-yield culture technology of selenium-enriched peanuts. By spraying a mixed nutrient solution with microelements such as boron and molybdenum and photosynthetic bacteria on the surfaces of leaves during different peanut growth periods and meanwhile spraying a selenium-enriched nutrient solution with a certain number of selenium elements, the effects of high yield, increased yield and stabile selenium element content are achieved for the peanuts, the yield per mu of the peanuts is improved by 30% through combination with a scientific and reasonable sowing and field management method; in addition, by mixing farmyard organic fertilizers, inorganic fertilizers and a certain amount of ammonium selenate for decomposition and stack retting before peanut sowing and meanwhile broadcasting the mixture before turning and plowing so as to combine soil fertilization with leaf surface fertilization, especially combine organic selenium application in soil with inorganic selenium application on leaf surfaces, the selenium content of the peanuts is increased, the selenium content of the peanuts produced through the technology is stabilized within the range from 0.18 mg/kg to 0.2 mg/kg, and the health care effect of the peanuts is greatly improved.

Description

technical field [0001] The invention relates to the field of peanut planting, in particular to a high-yield cultivation technique for selenium-enriched peanuts. Background technique [0002] Peanut is an important economic crop in my country. It is rich in fat and protein, and contains thiamine, riboflavin, niacin and other vitamins. It is also rich in minerals, especially amino acids necessary for the human body, which can promote the development of brain cells. It can be used to develop and enhance memory. It can be used as food or feed. It is not only an important industrial raw material, but also a bulk export commodity. It has a wide range of uses and plays an important role in the national economy. [0003] For a long time, there is no systematic and perfect high-yield cultivation method for peanut planting, so that the planting density of peanuts is not high, and the ventilation and light transmission conditions are poor, and the peanuts cannot perform photosynthesis ...

AI Technical Summary

Problems solved by technology

[0004] Selenium, as an essential trace element for the human body, has been paid more and more attention in the cultivation of crops, but it plays a lesser role in the growth of peanuts at present, mainly because the root system absorbs very little trace elements during the growth of peanuts.
