Selenium-rich oilseed rape planting method

Abstract

The invention relates to the technical field of oilseed rape planting, in particular to a selenium-rich oilseed rape planting method. The selenium-rich oilseed rape planting method comprises the steps that soil preparation is carried out and a base fertilizer is applied; rape seeds are soaked; the treated rape seeds are sown, and after sowing, the rape seeds are covered with nutrient soil which is prepared by fermenting astragalus sinicus and humic acid and compounding the fermented rape seeds with plant ash; topdressing is carried out, specifically, urea and monopotassium phosphate are topdressed in a 3-4 leaf stage of rape seedlings; a selenium-rich foliar fertilizer is uniformly sprayed once in the early stage of the bud and bolting stage of the oilseed rape, and the selenium-rich foliar fertilizer is prepared from the following raw material components in parts by weight: 2-4 parts of sodium selenite, 8-12 parts of chitosan, 6-8 parts of citric acid, 2-4 parts of r-aminobutyric acid, 3-5 parts of L-calcium aspartate, 12-18 parts of potassium chloride, 3-5 parts of erythritol and 200-300 parts of water; selenium-enriched foliar fertilizer is sprayed once in the flowering stage and the initial stage of seed setting correspondingly; and harvesting is carried out. According to the selenium-rich oilseed rape planting method, oilseed rape growth can be promoted, absorption of oilseed rape to selenium can be improved, and therefore, the selenium content of rapeseeds is increased; and meanwhile, the lodging resistance of the oilseed rape can be enhanced, and the yield of the rapeseeds is increased.

Description

technical field [0001] The invention belongs to the technical field of rapeseed planting, in particular to a method for planting selenium-enriched rapeseed. Background technique [0002] Selenium is an essential trace element for the human body. It has the functions of anti-cancer, anti-oxidation, enhancing human immunity, antagonizing harmful heavy metals, regulating vitamin absorption and utilization, and regulating protein synthesis. Selenium deficiency will lead to the decline of human immunity and the occurrence of various diseases. Therefore, selenium plays an extremely important role in human health. Eating fortified selenium medicinal and food preparations is a way of supplementing selenium, but these medicinal and food preparations are not suitable for human health. The utilization rate in the body is low, and there is a risk of side effects. As important organic selenium converters, selenium-enriched vegetables and selenium-enriched grains are the safest, most eff...

Problems solved by technology

Rapeseed planting methods include transplanting seedlings and direct seeding cultivation methods. Compared with seedling raising and transplanting methods, direct seeding cultivation methods can avoid damage to rapeseed seedlings during transplanting, reduce labor intensity, and reduce labor costs and planting costs. However, due to direct seeding Rapeseed has a high density, and the stems of rapeseed are thinner, which is prone to lodging of rapeseed, which greatly reduces the yield of rapeseed and reduces the quality of rapeseed
