摘　　要：以绵阳 2 6号、89-1 0 7为材料在川西平原的广汉市连山镇进行定位试验和比较研究表明 :免耕覆草栽培能显著增强小麦分蘖力 ,改善个体与群体质量 ,促进增产 ;省工节本 ,显著提高劳动生产率和经济效益 ;培肥地力 ,改善生态环境 。Experiments were conducted with cv. Mianyang 26 and 89-107 in 1992～1998 in order to test the effects of cultivation patterns on the grain yield and planting benefit of wheat .The results showed that the cultivation technique of zero tillage ,surface sowing and rice straw covering greatly increased wheat grain yield due to increasing tillers,improving the quality of individual plant and colony,and meanwhile,significantly increased the planting benefit because of reducing laborforce and decreasing cost.In additional,this cultivation pattern could fertilize the soil and improve ecological environment .
