宁夏扬黄限额灌区降水资源高效利用技术研究
Study on technology of efficient utilization of rainfall resources in supplementary irrigated area of pumping from Yellow river in Ningxia
摘要
Abstract
Taking corn plant as the object,integrating the technologies of micro-collection rainwater,soil water retention and inhibit transpiration on corn,this paper carried out the experiment on efficient utilization of rainfall resources in the arid area of middle Ningxia where the annual average rain is 350mm.By contrastive analysis of crop yield and efficiency of water in different modes of rainfall efficient utilization,it put forward appropriate rainfall resources utilization mode of corn with supplementary irrigation in arid area middle Ningxia witch is that turn the soil 20 to 40 cm,half coated,water retention agent (Qinweijiali 7.5 kg/hm2),inhibit transpiration agent (Wandaihong 1.05 L/hm2).The crop yield reached 13785kg/hm2,the utilization efficiency reached 4.22kg/m3.关键词
