Multi-microelement organic selenium-rich rapeseed cultivation method

Abstract

The invention discloses a multi-microelement organic selenium-rich rapeseed cultivation method. The method comprises the steps as follows: step 1, organic selenium compound liquid fertilizer is prepared: nano sugar alcohol organic selenium fertilizer and multi-microelement organic selenium fertilizer are mixed in proportion, water is added to the mixture for dilution, and the organic selenium compound liquid fertilizer is prepared for later use; step 2, the foliage fertilizer is sprayed in the full-bloom period and the early pod bearing period of rape; step 3, the interval period of each spraying is 6-8 days; step 4, rapeseeds are formed. Compared with the prior art, the method has the advantages that two high-tech achievements including nano sugar alcohol organic selenium fertilizer and multi-microelement organic selenium fertilizer and a nano chelation technology are integrated, optimized and combined, and the defect of single selenium and inorganic selenium supplement is overcome. In the key rape development period, enriched selenium is introduced at the most active stage and effectively absorbed, fixed, transferred and distributed, and organic-state selenium is further converted into plant-state selenium protein to be stored in seeds, so that the ideal selenium supplement source is obtained.

Description

technical field [0001] The invention relates to the field of research and development of new products of oil crops, in particular to a method for cultivating rapeseeds rich in selenium with multiple microorganisms. Background technique [0002] Selenium has been proven to be an essential trace element for animals and the human body, a nutrient element beneficial to plant growth, an important component of various enzymes and proteins in organisms, and has the functions of improving human immunity, anti-aging, and preventing cancer. Eating selenium products is the most economical, effective, safe and convenient way to supplement selenium. [0003] 72% of the country's soil is deficient in selenium or seriously deficient in selenium. Therefore, most agricultural products have the problem of low selenium content, and people's health is greatly threatened. The incidence of chronic diseases, mainly tumors and cancers, is increasing year by year, and the mortality rate is constant...

Problems solved by technology

However, due to selenium deficiency in rapeseed fields (fields), the soil environment deteriorates, the quality of rapeseed is very poor, and trace elements are lacking, so it is difficult to improve the benefits.
