Method for planting oilseed rape

Abstract

The invention discloses a method for planting oilseed rape. According to the method, an aqueous solution containing sodium selenite is added during germination accleration, and the concentration of the solution is controlled, so that selenium-enriched oilseed rape seeds can be screened, the accumulation of selenium in seeds of rapeseeds can be increased, and a number of pathogenic micro-organisms in the seeds can be killed; thinning and topdressing are beneficial to improving growth of oilseed rape seedlings and increasing the field yield; molybdenum fertilizer, potassium dihydrogen phosphate, boron fertilizer and water are mixed and uniformly sprayed to the leaf surfaces of oilseed rape during the flowering phase of oilseed rape, so that yellow oilseed rape leaves and flower abscission can be prevented, and the content of molybdenum in the seeds of rapeseeds can be increased; chemicals for preventing powdery mildew and killing aphids are used during the initial flowering phase of the rape, so that sclerotinia sclerotiorum and the aphids can be prevented and controlled. Oilseed rape planted by adopting the method has the advantages of high germination rate and high yield, and has huge market potential and wide prospect.

Description

technical field [0001] The invention belongs to the field of agricultural planting methods, and more specifically, the invention relates to a planting method of rapeseed. Background technique [0002] Due to the large leaves and high leaf area index of rapeseed, rapeseed is planted with traditional specifications, and the participation of agricultural machinery in field management will cause serious mechanical damage such as leaf breakage, which will affect the normal growth of rapeseed. Large, high cost. In recent years, with the acceleration of urbanization and the migration of rural labor to work in cities, problems such as insufficient labor input in rapeseed production have become the main factors restricting the development of rapeseed production. The phenomenon of extensive management leads to weak growth of rape seedlings, weak ability to resist natural disasters such as drought and freezing damage in the later period, and aggravates the occurrence and damage of weed...

[0002] Due to the large leaves and high leaf area index of rapeseed, rapeseed is planted with traditional specifications, and the participation of agricultural machinery in field management will cause serious mechanical damage such as leaf breakage, which will affect the normal growth of rapeseed. Large, high cost. In recent years, with the acceleration of urbanization and the migration of rural labor to work in cities, problems such as insufficient labor input in rapeseed production have become the main factors restricting the development of rapeseed production. The phenomenon of extensive management leads to weak growth of rape seedlings, weak ability to resist natural disasters such as drought and freezing damage in the later period, and aggravates the occurrence and damage of weed damage, clubroot, aphids and other diseases, insect pests and weeds, resulting in low and unstable yields. Rapeseed As a cruciferous plant, it has a good ability to accumulate selenium
