山西陵川县农机局在近几年全县大力推广机械化平播小麦技术的基础上,1990年秋,又引进示范了小麦沟播技术。县农机局组织技术人员在一块5亩大的地块上,分别进行了小麦沟播、平播、土耧播的三种不同播法的对比试验。在地力、播期、品种、施肥等相同的条件下,机沟播、平播分别比土耧播种出苗期提前二天和一天。出苗率分别比土耧播提高15%和9%左右。分
Shanxi Lingchuan County Agricultural Machinery Bureau in recent years, the county vigorously promote the mechanization of flat-screen wheat technology, based on the autumn of 1990, but also the introduction of demonstration of wheat gully technology. County Agricultural Bureau organizational technical staff in a 5-mu large plot, respectively, the wheat sowing, flat-screen, soil sowing of three different sowing comparison test.
