Efficient two-cop one-year planting method for tobacco-rapeseeds in cold tobacco region in north

Abstract

The invention belongs to the technical field of crop rotation planting of tobacco and discloses an efficient two-cop one-year planting method for tobacco-rapeseeds in a cold tobacco region in the north. The method comprises the following steps: performing crop rotation engagement of tobacco-rapeseeds, namely preparing a land and applying a basic fertilizer; planting rapeseeds, namely performing seed sowing, field management and maturation harvesting; performing crop rotation engagement of rapeseed-tobacco, namely preparing the land, forming ridges, applying a basic fertilizer, and performing film covering; and planting tobacco; namely performing seedling breeding, transplanting, field management and maturation harvesting and baking. By adopting the method, the problem of soil problems caused by a single-crop continuous cropping mode in conventional tobacco planting in a tobacco region in the north can be effectively solved, soil nutrients can be balanced, development of root systems can be promoted, accumulation of harmful substances and diseases and insects can be reduced, the yield of tobacco leaves can be increased, the quality of the tobacco leaves can be improved, and the comprehensive economic benefits of a tobacco field can be increased. By adopting the method, the content of organic matter in soil can be increased by 15-25%, structures of plough layers are remarkably improved, the occurrence rate of diseases and insects can be reduced by 60%, the ratio of high-quality cigarette of the tobacco leaves can be increased by 5-7%, chemical component harmony and sensory evaluation of the tobacco leaves is remarkably improved, and the comprehensive economic benefits of farmers can be increased by 15-20%.

Description

technical field [0001] The invention belongs to the technical field of tobacco rotation planting, and in particular relates to a high-efficiency planting method of tobacco and rapeseed twice a year in cold and cold tobacco areas in northern China. Background technique [0002] At present, the tobacco planting mode is a set of methods adopted in order to achieve the layout and distribution of tobacco and other food crops or economic crop planting structures under certain natural resources and socio-economic conditions, and to achieve the improvement of crop product quality and sustainable development. The comprehensive technical system combining land use and land cultivation, including planting arrangements, farming methods and supporting technical measures, is one of the key links in the tobacco cultivation and farming system. Adopting a reasonable farming pattern in tobacco leaf production can not only reduce the occurrence of diseases and insect pests, coordinate the suppl...
