摘要
【目的】为了解决我国秸秆焚烧、废弃、利用率低所带来的资源浪费和环境污染等问题.【方法】设计了秸秆深施还田机.该机能在秸秆还田作业的同时完成秸秆深施还田和土壤深松,并对其深施铲的行进阻力进行了正交试验研究.【结果】深施铲的行进阻力随着深施铲铲宽、土壤容重和深施铲入土深度的增大而增大,在这3个因素中深施铲入土深度对其影响最大,深施铲铲宽次之,土壤容重对其影响最小;深施铲铲宽与入土深度两因素之间的交互作用对深施铲行进阻力的影响显著(P<0.05),深施铲铲宽与土壤容重、土壤容重与入土深度之间的交互作用对深施铲行进阻力无显著影响.【结论】研究结果可以为秸秆深施还田技术的深入研究,以及配套机械装备的研发提供参考.
[Objective] The research aimed to reduce resource waste and environmental pollution caused by the burning,wasting and low utilization of straw in China. [Method] A straw deep-application machine was designed. The machine could finish the straw deep-application returning and loosening deep soil at the same time. The travel resistance of deep-application shovel was studied by orthogonal test. [Result] The travel resistance of the deep-application shove rose with the increasing of application shovel width, soil bulk density and depth into soil, among which the depth into soil affected the resistance most, the shovel width took the second and soil bulk density took the third. The interaction between depth into soil and the shovel width on the resistance was significant （P〈0. 05）,while the interaction between the other two group fac- tors appeared insignificantly. [Conclusion] Design of the straw deep-application machine and resistance test study of the deep-application shovel can provide reference for further study on the straw deep-application- returning technology and development of matched machine.
