为缓解我国秸秆焚烧及废弃所带来的资源浪费和环境污染等问题,设计了秸秆深施还田机,可一次完成秸秆捡拾、切碎和深施还田作业.同时,对其秸秆深施装置的秸秆深施量进行了正交试验研究,试验结果表明:秸秆含水率对秸秆深施量影响较大,深施螺旋转速次之,秸秆长度影响较小;秸秆深施量随深施螺旋转速的增大而增加,随秸秆长度和秸秆含水率的增大而减少.在该试验条件下,深施螺旋转速为540r/min、秸秆含水率为10%、秸秆长度为5 mm时,秸秆深施量最大.

In order to alleviate the wasteful resource and environmental pollution problem which are caused by burning, wasting and low utilization rate of straw in China, designing the straw deep-application returning machine that can simul-taneously finish the task of picking, chopping and deep-application returning straw an operation.After analyzing the data of the amount of straw deep-application which can be found in straw deep-application device in orthogonal experiment, it showed that: the water ratio of straw had the biggest influence on the amount of straw deep -application and the influ-ence of the rotate speed of deep-application helix was smaller than straw moisture content.The length of straw ' s influ-ence was the smallest among the three elements.Also, the experiment showed that:the amount of straw deep-application had been increased when the rotate speed of deep-application helix improved while the water ratio of straw and the length of straw decreased at the same time.Under the condition of the test, when the rotate speed of deep-application is 540 r/min, the water ratio of straw is 10%and the length of straw is 5mm, the amount of straw deep-application is the largest.
