摘要
根据雨水叠加利用原理 ,在坡地留出一部分地铺膜作为集雨区 ,以减缓种植区小麦水分亏缺的矛盾。结果表明 ,集雨区与种植区面积比为 1∶ 1时 ,种植区的土壤水分条件得到明显改善 ,种植区小麦的个体发育良好 ,产量增加 ,增产率为 51 .38% ,水分利用效率提高 ,比对照提高 2 .2 7kg/ (mm· hm2 )
According to the principle of rainfall collection using, some slope field is left as rainfall collection area to provide water to plant area, and to decrease water deficit of wheat in plant area. The result shows, if the ratio of rafall collection area to plant area is 1∶1, the soil water condition of plant area will be improved obviously, single development of wheat in plant area will grow better, the yield will be increased by 51.38%, and WUE is raised 2.27 kg/(mm·hm 2) compared with the check plot.
