Rapeseed planting and harvesting method

Abstract

The invention provides a rapeseed planting and harvesting method. The rapeseed planting and harvesting method comprises the following steps: selecting a planting field, preparing soil, carrying out field division treatment, selecting seeds, pretreating rape seeds, carrying out seedling raising and transplanting, carrying out field management, carrying out harvesting and threshing, and carrying outsieving and drying treatment. According to the method, the germination rate of the rape seeds and the survival rate of rape seedlings can be increased through large granulation treatment, soil acidity and alkalinity of the planting field can be adjusted by scattering plant ash during soil preparation, so that the soil is more suitable for growth requirements of the rapeseeds; meanwhile, the plantash contains a lot of potassium elements, so that soil fertility can be improved; the plant ash can further kill underground diseases, pests and germs, protect seeds, roots and stems of the rapeseeds, and reduce plant diseases and insect pests; root production of the rape seedlings can be promoted by using a clean biogas fertilizer as a topdressing fertilizer, and the fertilizer effect absorptionof the clean biogas fertilizer and organic fertilizers is fast, so that growth of the rape seedlings can be promoted, the growth cycle of the rape seedlings is shortened, the yield of the rapeseeds can be increased, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of rapeseed planting, in particular to a method for planting and harvesting rapeseed. Background technique [0002] Rapeseed is an excellent crop. The fruit of mature rapeseed is rapeseed. Rapeseed is rich in vegetable oil and can be pressed for people to eat. The rapeseed oil extracted from rapeseed is rich in unsaturated fatty acids. It can be well absorbed by the human body, and the absorption efficiency reaches 99%; and eating rapeseed oil can clear the liver and gallbladder, reduce blood lipids and lose weight. [0003] The rapeseed yield per unit of rapeseed planted by the existing rapeseed planting technology is not high, and at the same time, the rapeseed is prone to turn green due to improper field management during the mature stage, which greatly reduces the rapeseed yield, and the existing rapeseed planting technology. A large number of chemical fertilizers and pesticides are used for fertilizati...

Problems solved by technology

[0003] The per unit yield of rapeseed planted by the existing rapeseed planting technology is not high. At the same time, the rapeseed is prone to turn green due to improper field management during the mature stage, which greatly reduces the rapeseed yield. Moreover, the existing rapeseed planting technology A large number of chemical fertilizers and pesticides are used in fertilization, insect control and weeding, resulting in high chemical fertilizer and pesticide residues in the planting field, which will destroy the soil nutrients, and the nutrient content of the rapeseed planted will also be reduced. Due to the crisp and brittle characteristics of rapeseed shells, it is easy to cause a large number of rapeseeds to fall and cause losses
