根据1992~1994年在北方旱区农业综合发展研究的寿阳试验区的农田水分平衡定位试验资料,研究分析了旱地春玉米田微集水保墒技术的蓄水保墒效果。结果表明:微集水处理的降水入渗深度比对照增加;微集水处理的0~200cm土层的蓄水量,在玉米苗期、需水关键期和成熟收获期均比对照增加;农田微集水保墒技术有调控农田蒸散量的作用;农田微集水保墒技术有明显的增产作用,且在旱年更为显著;微集水保墒技术使水分利用效率高
According to the experimental data of the farmland water balance in the experimental area of Shouyang in 1992 ~ 1994 in the comprehensive agricultural development in the northern arid region, the effect of water storage and soil conservation on the moisture and soil moisture conservation in spring maize field was studied. The results showed that the infiltration depth of micro-catchment increased more than that of the control. The water storage of 0-200cm soil layer of micro catchment increased than that of the control at the seedling stage, critical period of water requirement and mature harvest stage. Micro-collection of water and soil moisture conservation technology has the role of evapotranspiration; farmland micro-water and soil moisture conservation technology has obvious yield increase, and more pronounced in dry year; micro-water conservation technology makes water use efficiency
