平坝地区开展人工种草,采用草粮套作的方式较为普遍。春季在草地上套种包谷时,部份农户采用传统的直播方法,缺窝断行后再采取补苗措施,这种作法既花工又费种,还影响粮食产量。据调查,1985至87年,全县实行粮草套作869.6亩,育苗移栽130亩,占套种面积的15%。这部份苗齐而壮,亩产包谷260至330公斤,牧草3000至5000公斤,获得了粮草双丰收。而采用直播的730亩中,齐苗的占30%,多数属当年播种草厢间的套种。缺苗采取补苗 Pingba area to carry out artificial grass, grass-covered sets of methods are more common. When spring intercropping corn in the meadow, some farmers use the traditional direct seeding method. After missing their nests, they take supplementary seedling measures. This is not only labor-intensive and costly, but also affects grain yield. According to the survey, from 1985 to 1987, the county implemented 869.6 hectares of forage grass and 130 mu of transplanting seedlings, accounting for 15% of the area planted. This part of the nursery stocky and strong, per mu Valley Valley 260 to 330 kg, pasture 3000 to 5000 kg, won the forage double harvest. The use of 730 acres of live, Qi Miao accounted for 30%, most of the sowing inter-year inter-species intercropping. Lack of seedlings to take seedlings
