2.1 技术简介

技术定义:

Subsoiling with mulching is cultivated using plough without disturbance of surface soils but loosing the subsoils.

2.2 技术的详细说明

说明:

Subsoiling with mulching is one of the conservation tillage technology, it is to deep till to loose subsoils without disturbance of surface soils, it is combed with residuals coverage(straw). The purpose of the technology is to let all rainfall infiltrate in soil without runoff occur and incease soil moisture and organic matter content in order to raise yield.

注释:

Major land use problems (compiler’s opinion): Traditional tillage (multi-tillage) has made soil loose and easily being moved on the dry and semi-dry farmland. Subsoiling is a suitable way for slope cultivated land in keeping rainfall in soil with mulching that enhance content of soil organic matter and reducing wind erosion.

Major land use problems (land users’ perception): Practical and low input by using this technology, also easy to operate.

Type of cropping system and major crops comments: Winter wheat--corn/sweet potato--winter wheat
