土壤的合理耕作管理,可以影响土壤肥力因素“水、肥、热、气”等条件的变化,活化土壤潛在养分,调节土壤营养环境,控制作物个体生长发育的协调,使群体得到良好的发展,从而增加产量。提高麦田耕作管理质量,不仅能提高供肥能力,为当季作物丰产打下基础,而且能为后作增产创造条件。我省作物复种指数逐年提高,由于施肥水平不相适应,使部分地区的大小麦产生“多种”与“单产提高”的不协
The rational management of soil can affect the changes of soil fertility factors such as “water, fertilizer, heat and gas”, activate the potential nutrients in soil, regulate the soil nutrient environment, control the coordination of crop growth and development, and make the population get good development. Thus increasing production. Raising the quality of tillage management in a wheat field will not only improve the ability to supply fertilizers, lay the foundation for the crop’s high yield in the current season, but also create the conditions for future increases in production. The index of crop multiplication in our province has been increasing year by year. Due to the incompatibility of fertilization levels, large and small wheat in some areas produce “multiple” and “single-crop improved” associations
