保护性耕作是用大量秸秆残茬覆盖地表,通过减少耕播种,合理深松,用化学药物控制杂草和病虫害,尽可能减少田间的耕作,提高农业综合生产能力。其主要内容是秸秆残茬覆盖地表、免少耕播种、化学防治杂草和病虫害、合理深松,从而改善农业生产条件,提高综合生产能力,将农民从繁重的农业作业中解放出来,实现粮食增产、农场清洁、资源利用的有效结合,也是降低农业生产成本、促进农民增收的有效途径之一,它省工、省时、节省费用,不仅可以降耗,而且可减少土壤耕作次数,减少作业成本,可以充分利用降水资源,利于保水、保墒。
Conservation tillage is to use a large number of straw stubble cover the surface, by reducing tillage, rational subsoiling, chemical weed control and pests and diseases, minimizing tillage in the field and improve the comprehensive agricultural production capacity. Its main contents are straw stubble covering the surface, no-tillage sowing, chemical weed control and pests and diseases, reasonable subsoiling, so as to improve agricultural production conditions, improve comprehensive production capacity, liberate peasants from heavy agricultural operations and realize food It is also an effective way to reduce the agricultural production cost and increase the peasants’ income. It saves labor, saves time and saves costs, which can not only reduce consumption, but also reduce the times of soil cultivation and reduce the workload Cost, you can make full use of precipitation resources, which will help keep water and soil moisture.
