施耕是利用动力旋转机械进行耕作,目前已在我省得到越来越广泛的运用。与传统的犁耕相比,施耕有自己的特点。首先它不造成像犁耕那样的犁沟,因而不需要填平犁沟,可以节省劳动力。其次,碎土性能好,省工节能。施耕机的工作过程是刀齿一面作高速回转运动,一面随机组前进。土垡被刀齿切下后向后方抛出撞击滚筒的疬板和挡(?),被碎成更为蛔小的土粒下落。耕作效果相出于耕、(?),平三项作业,减少了作业次数,总能耗减少,旋耕质量好,不误农时。但旋耕后草根草种留在表层,灭草作用较犁耕盖。藁城县盂村连续几年旋耕后,麦田杂草明显增多。因此,采用旋耕虚注意以下几点:①固旋耕灭草作用盖,应在草少的地块采用。②采用旋耕与犁耕相结舍,旋耕几年后应犁耕一年,以压低杂草密度。③旋耕后土体较膨松,能促进有 Shigeng is the use of power rotary machinery for farming, now in our province has been more widely used. Compared with the traditional plow, Shigeng has its own characteristics. First of all, it does not create furrows like plows, so there is no need to fill furrows and labor can be saved. Second, good soil properties, energy-saving workers. Shige machine work process is the knife side for high-speed rotary movement, while the random group forward. Soil cut by the knife after the tooth is thrown to the rear of the impact of the drum plate and block (?), Broken into smaller round soil particles fell. Tillage effect out of tillage, (?), Flat three operations, reducing the number of operations, reduce the total energy consumption, rotary tillage is good, not wrong farming time. However, after tillage grass leaves grass species remain in the surface, weeding than plow cover. Tancheng County Village for several years after rotary tillage, wheat weeds increased significantly. Therefore, the use of rotary tillage to note the following points: ① solid rotary weeding effect cover, should be used in grass-less plots. ② The use of rotary tillage and plow farming homes, rotary tillage a few years should plow for a year to reduce the weed density. ③ Rotary soil after the more bulky, can promote there
