机械整地与作垄是机耕系列化的基础作业。1973年盖县红旗公社70%的耕地采用了机械作垄,积累了一些经验。1.抓早抓紧,耙压保墒红旗公社漏风土多,常遭春旱。为了保好墒情,当土地化冻6～7厘米深时,赶忙顶凌耙压。对机具进行合理编组,周密安排调车计划,既提高了作业效率,又确保了墒情。 Mechanical land preparation and furrowing is the basis for the operation of the series. In 1973, 70% of the farmland in Hongqi Commune of Gaixian County used machinery as a ridge and accumulated some experience. 1. Grasping the early pay close attention to water conservancy RED rake earth leakage, often spring drought. In order to maintain the moisture content, when the soil is frozen 6 ~ 7 cm deep, quickly top pressure rake. Reasonable grouping of machinery, scheduling shunting arrangements, both to improve operational efficiency, but also to ensure that the moisture content.
