将蚕豆‘青海13号’有效地整合到青海旱作农业系统，并配套地膜覆盖种植技术提高旱作农业系统蚕豆的综合生产能力，对有效扩大青海蚕豆种植区域具有重要意义。在旱作农业区通过地膜覆盖和裸地种植两个处理分析了地膜覆盖种植对‘青海13号’蚕豆的增产作用。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，促进了蚕豆生长发育，生育进程提前了约1周；同时，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%，从而使‘青海13号’蚕豆在地膜覆盖种植后产量增加了23.55%。

This technology of plastic film mulching was applied in faba bean, to effectively integrated‘Qinghai No.13’into the rained agricultural system, and improving the production capacity. It is important for effectively expanding the broad bean planting area in Qinghai. In arid agricultural areas plastic mulching and bareness planting was used and analyses the yield-increasing effect of‘Qinghai No.13’plastic mulching. The results was showed that the plastic mulching improved significantly soil temperature and soil moisture in plough player, the average soil temperature increased 2.4℃, soil moisture increased by 14.1%. It is good for cultivating strong seedling and growth, made growth period earlier about 1 week. The dry matter accumulation was increased significantly by 148.14% in maturity of‘Qinghai No.13’. Number of pods per plant, grain number per plant and yield increased respectively by 121.7% , 87.4% and 87.4% , so that the yields of ‘Qinghai No.13’was increased by 23.55% after plastic mulching cultivation.
