摘　　要：为探讨旱作农业区地膜覆盖种植技术对蚕豆的增产效应,采用对比法进行了试验。结果表明:地膜覆盖后明显改善了耕作层的土壤温度和土壤湿度,平均土壤温度提高了2.4℃,土壤湿度提高了14.1%,有利于旱作农业区蚕豆的出苗,也加快了生育进程约7d;地膜覆盖种植蚕豆后,株高、干物质积累明显提高,成熟期干物质积累增加了148.14%;单株荚数、单株粒数、单株产量分别提高了121.7%、87.4%、90.4%,产量增加23.55%。For explore effect of increasing yiold for faba bean production based on plastic film mulching cultivation in arid agricultural areas, comparative study were adopted on test. The results was showed that the soil temperature and moisture of mag- netism was significantly improved after plastic film mulching, the average soil temperature increased by 2. 4 ℃, soil moisture increased by 14. 1%, and promotes faba bean germinating in arid agricultural area beans, also sped up the development process about 1 week; At the same time, the plant height and dry matter accumulation of faba bean was increased significantly, especially, the mature period of dry matter accumulation increased by 148. 14% through plastic mulching cultivation of faba beans,. Pod number per plant, grain number per plant, yield increased by 121.7%, 87. 4% and 87. 4%, respectively, yield increased by 23. 55%.
