1993年我们将地膜覆盖技术应用于谷子后,667m2产量从不覆膜的150kg提高到300kg。在4a的试验、示范、推广中,与有关部门联合攻关,有效地解决了播种方式、播种机械、播种密度等关键问题,总结出了一套667m2产量上千斤的综合栽培技术,深受群众喜爱,种植面积逐年扩大,1997年全县种植 In 1993, after we applied the technology of mulching to millet, the yield of 667m2 was increased from 150kg without coating to 300kg. During the experiment, demonstration and promotion of 4a, the joint research with the relevant departments effectively solved the key problems such as sowing methods, sowing machinery and sowing density and concluded a set of integrated cultivation techniques with a yield of 667m2, which was greatly favored by the masses , Planting area expanded year by year, in 1997 the county planted
