当前,耕作方面的研究工作着重于降低能量消耗,减少作物受污染,以及防止土壤受侵蚀等。一.关于犁体尺寸的研究近年来,由于带茬耕作有所发展,犁的作业速度和拖拉机功率也在增加,因而犁体幅宽也从12时或14时增加到16、18甚至20时。犁体加宽的理由是为了提高覆盖质量、减少机体零件、便于维修保养以及开出较宽的犁沟以适应大型拖拉机的轮胎。 Currently, farming research focuses on reducing energy consumption, reducing crop pollution, and preventing soil erosion. In recent years, due to the development of stubble cultivation, plow operating speed and tractor power are also increasing, so the plow body width also increased from 12 o’clock or 14 o’clock to 16, 18 or even 20 o’clock . The reason for widening the plow body is to improve the quality of the cover, reduce the body parts, ease of maintenance and widening furrows to fit the tires of large tractors.
