摘　　要：探讨了日光温室中施用有机肥料BGA激活剂后土壤水分动态规律,试验结果表明:BGA激活剂作为一种有机肥料对于保持土壤水分有着明显的作用,施加BGA的土壤含水率要比对照处理高出17.7%;施加BGA后通过水分运移,在根系分布密集的20～60 cm之间的土壤含水率较高,其中20～40 cm的土壤含水率增加26%,40～60 cm的土壤含水率增加28%;试验研究发现,当BGA的施加标准为150 g/株,作物根系土层含水率增加最多.BGA作为一种有机肥料,为发展节水农业提供了一种新的途径.An experiment to study the effects of organic manure-BGA on soil water movement, distribution in solar greenhouse in Daxing Water Saving Demonstration site of Beijing was conducted. And the results show that BGA is good to maintain the soil water, the soil water content increased by more than 14.5%~28.5% by using BGA. The soil water content is higher at the depth of 20~60 cm, where the melon roots are densely distributed in the same layer. When the dosage to every plant of BGA is 150 g, the soil water content accelerates sharply. As a new type of organic manure, BGA is helpful to save the water resource.
