Abstract:

Crop straw returning is an important technical way to increase soil fertility, which can effectively solve the environmental problems caused by straw waste and field straw burning. In order to study the technology of straw returning and use straw returning efficiently and rationally, this study reviewed the current situations of the utilization of crop straw resources, the approach of straw returning, and the common technical modes and applications of straw returning. The effects of crop straw returning on the ecological environment of farmland and crop yield were elucidated. This study also analyzed the advantages and disadvantages of straw returning and proposed the directions of future research, and then pointed out that the key to the future development of crop straw returning is to combine agronomy with agricultural machinery.

Key words: straw returning, crop, crop straw resources, method, technical mode, effect
