Straw Returning Machinery and Factors Affecting Its Degradation
-
摘要: 秸秆还田是最普遍的秸秆综合利用形式,在秸秆的五化综合利用中居首要地位。国外的秸秆粉碎还田技术起步早,秸秆还田技术与机械相对成熟。相比较我国的秸秆粉碎还田技术还处于初期阶段,秸秆还田机械的局限性较明显。另外,秸秆还田后,由于多种因素的影响,导致田间腐解效果不理想。简要介绍了国内外秸秆利用情况、秸秆还田机械,总结归纳了影响秸秆还田后腐解的一些因素,以期为秸秆快速腐解还田提供一定参考。Abstract: Straw returning to the field is the most common form of comprehensive utilization of straw,and it occupies the first place in the comprehensive utilization of straw in the five modernizations. The straw crushing and returning technology in foreign countries started early,and the straw returning technology and machinery are quite mature. Compared with the straw crushing and returning technology in my country,it is still in the early stage,and the limitation of straw returning machinery is obvious. In addition,after the straw is returned to the field,due to the influence of various factors,the decomposing effect in the field is not ideal. This paper briefly introduces the utilization of straw at home and abroad and the straw returning machinery,and summarizes some factors that affect the decomposition of straw after returning to the field,in order to provide a certain reference for the rapid decomposition of straw returning to the field.
