机械化旱作节水技术的应用

Applications of Water-saving Techniques in Mechanized Dry Farming

彰武县是典型的北方旱作农业区,旱灾频繁,全县绝大部分耕地无水浇条件。详细介绍秸秆覆盖及高留茬、机械化深松及重耙压、地膜覆盖3项技术的内容和效果,通过多种作业模式的机械化旱作节水技术集成示范基地建设项目,探索旱作条件下依靠天然降水实现大面积旱作农田保土保肥、抗旱保水节水、增产增收的有效途径。

Zhangwu County is a typical dry farming area in the north of China where drought often strikes and most of the land lacks water irrigation conditions.This article expounds on the content and effect of three water-saving techniques,including straw covering and stubble left high,mechanized subsoiling and pressed with heavy rake,and plastic mulching.In addition,the author examines various ways to fight against drought in dry farming areas with the aim of increasing yields and economic returns.
