保护性耕作是以机械化作业为主要手段,采取少耕或免耕方法,将耕作减少到只要能保证种子发芽即可,用农作物秸秆及残茬覆盖地表,并主要用农药来控制杂草和病虫害的一种耕作技术。随着传统翻耕技术的发展,人类和自然的矛盾愈来愈突出,比如耕翻作业除掉地面残茬、杂草固然有利于播种,但同时也破坏了对地面的保护,导致土壤风蚀、水蚀加剧;旋耕切碎土壤,创 Conservation tillage is a mechanized operation as the main means to take less tillage or no-tillage methods, reducing tillage as long as it can ensure that the seeds germinate, covering the surface with crop stalks and stubble, and mainly pesticides to control weeds and pests and diseases A farming technique. With the development of the traditional tillage technology, the contradiction between human and nature is more and more prominent. For example, tilling over the ground to remove stubble, weeds are certainly conducive to sowing, but also undermine the protection of the ground, leading to soil erosion, Increased water erosion; Rotary shredded soil, create
