摘　　要：多年的试验结果表明 ,采用微型聚水地膜覆盖技术 ,使渭北夏闲地高效利用成为可能 ;利用夏闲地种植一料矮生菜豆与传统耕作方法相比 ,对 2 m土层水分状况影响不大 ,并在不影响下茬小麦的情况下 ,每公顷可收鲜豆荚 1 1 2 50 kg～ 1 50 0 0 kg,收入达 60 0 0元～70 0 0元 ,有推广价值。Experimental results for many years show that application of the technique of micro water harvesting and plastic film mulching makes it possible to use summer fallow land in Weibei tableland more efficiently. Compared with conventional tillage, planting dwarf beans in summer fallow land affects soil water content in the 2 m layer very slightly. Without causing any sequences to the growth of the following wheat, an additional harvest of 11 250 kg^15 000 kg/hectare beans can be obtained, which means an income of 6 000 yuan^7 000 yuan. So this technique is worth extending to a larger area.
