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.
