| 摘 要： | 保护性耕作技术是众多减少土壤侵蚀方法中的一种。从广义上来说，保护性耕作是对一种耕作体系的定义，是指在作物收获后，将足够的谷物秸秆覆盖在地表以保护土壤不被侵蚀。总的来说，覆盖量达到30％时．就被认为是保护性耕作。根据土壤类型、谷物轮作方式、冬季作物以及其他的因素，秸秆覆盖方式有所不同？

The Role of Education and Technical Assistance in the Use of Conservation Tillage |

| Abstract: | Conservation tillage is one of many conservation practices developed to reduce soil erosion. In its broadest sense, conservation tillage is defined as a tillage system that leaves enough crop residue on the field after harvest to protect the soil from erosion. In general, tillage that leaves a residue cover of at least 30% is deemed conservation tillage. Residue cover will vary, however, according to soil type, crop rotation, winter crop cover and other factors. |
