我省整地虽早已实现机械化,但由于多种因素影响,每年春秋两季都有很多应翻而翻不过来的地,这自然涉及到五铧犁作业效率的问题。根据两年多生产实际的测试,我们认为,要提高五铧犁作业效率,必须合理配备机具,挖掘生产纯作业时间。田间作业测定,东方红—75拖拉机翻地作业班次综合平均时间的构成是: Although the province has long been mechanized land preparation, but due to a variety of factors, the annual spring and autumn there are many should be turned over to turn over, which naturally involves the five-plow operating efficiency issues. According to more than two years of actual production testing, we believe that to improve the operating efficiency of the five-hull plow, it is necessary to equip the utensils properly and excavate the pure operation time. Determination of field operations, Dongfanghong -75 Tractor Landing Operations consolidated average time structure is:
