东北稻区秸秆直接还田技术与机具研究进展OA北大核心CSTPCD

Direct returning of straw as the main content of protective tillage had been widely used in the northeast rice areas.This article summarized the main technical models and supporting machines of direct straw returning in the northeast rice area of China,and analyzed the working principle and technical characteristics of different kinds of machines in each link.Based on explaining the existing problems and shortcomings of existing straw direct returning field technology and supporting equipment,we recommended to focus on research on rice straw cutting technology,power throwing technology,component materials,and processing technology,component prevention technology,cost control of straw departure field,straw stubble and full area leveling technology,agricultural machinery,and agricultural integration research.Hope to provide equipment and technical support for the direct field technology and machinery research of straw back to the northeast rice area of China.
