采用垅作时,每年春播前都要把玉米、高粱、谷子等的茬子刨掉。这项作业,既费劳力又破坏墒情。去年年初,我所手扶拖拉机驾驶员在手扶拖拉机上安装上自己改制的割茬子部件,经冬春在四百五十亩地上的生产试验,效果很好,达到了割子茬的农业要求,割下的茬子基本坐在垅上,保墒也较好。割茬子部件用于垄作,化冻不超过3厘米或不化冻的丘陵岗地,可割玉米、高粱、谷子茬等。割茬子部件(图1)主要由割刀焊合件、前支架组成。割刀是两块犁铧(翻
When using crop, corn, sorghum, millet and other stubble should be planted out before the spring seeding. This operation is laborious and destroys the moisture content. At the beginning of last year, the tractor pilot of our company installed the self-made cutting parts on the walking tractor. After the winter and spring production tests on 450 acres, the result was very good and the agricultural requirements of cutting stubble , Cut off the basic sitting in the stubble, soil moisture is better. Stubble sub-components for the ridge, frozen not more than 3 cm or not fossil hilly posts, cut corn, sorghum, millet stubble and so on. Cutting stub sub-components (Figure 1) mainly by the cutter welding parts, the former bracket. Cutter is two plowshare (turn
