| 中文摘要: |
| 根据国内外有关免耕的试验研究成果,总结了免耕措施对粮食生产及农田经济效益的影响。对于干旱缺水的我国北方地区,如果采取合理的作物轮作,科学的去除杂草方法,免耕后粮食产量一般还高于传统耕种,同时,由于节能、省工、减少操作工序和生产成本等,免耕的投入产出效益也往往高于传统耕作。 |
| 英文摘要: |
| On the base of evaluation of previous research achievements on no-tillage,the paper summarizes the influences of no-tillage technology on crop yields and economic benefit.The results show that in the arid area of North China,if the rotation systems of different crops and the scientific weeding method are adopted,no-tillage technology could increase grain yield,and the output benefit of no-tillage is higher than that of conventional tillage. |
