近些年来,不少棉区由于重用轻养,使棉田有机质含量普遍下降。棉秆若能返田作肥,将是解决棉田有机质肥料的措施之一。但是,棉秆棵大质硬,未经切碎,不易翻沤和腐烂。为此,我所于一九八○年从中棉所引进了该所研制的4 MGS—2型棉秆田间切碎机,进行了田间试用,效果基本良好。该机原以东方红——28轮式拖拉机作动力,与我所丰收45型拖拉机不配套,经对切碎机动力输入轴花链套和三点悬挂秆进行改装后,使用正常。试用证明,三档是最佳作业速度,作业效率每小时可达5—6亩,碎秆抛撒均匀,棉根均可在地表一寸以下切断。若将棉地横直沟交叉点以土填平,则作业机
In recent years, many cotton areas due to re-use of light, so that the general decline in organic cotton content. Cotton stalk if the return to the field for fertilizer, will be one of the measures to solve the organic fertilizer in the cotton field. However, the cotton stalk trees are hard, unmilled and hard to overturn and decay. For this reason, in 1980, I introduced the 4 MGS-2 type cotton stalk field shredder developed by CIMC and conducted field trials with good results. The aircraft was originally Dongfanghong - 28 wheeled tractor as a driving force, and my bumper harvesting 45 tractors do not match, after the chopper power input shaft flower chain cover and three-point suspension stalk modified, the use of normal. Proof of trial, the third gear is the best operating speed, operating efficiency of up to 5-6 acres per hour, throwing broken shreds, cotton roots can be cut off below an inch in the surface. If the intersection of cotton cross-trench straight to fill the soil, the job machine
