Abstract:In recent years greenhouses are expanding rapidly for vegetable cultivation in Shanxi,but blindness in irrigation、fertilization and pesticide application in greenhouse cultivation are causing a series of problems,such as waste of water,lower fertilizer use efficiency,salt accumulation,contamination of farm produce and reduced benefit of investment.Based on findings of the investigation of these problems,a new technical scheme named integrated management of water and fertilizer,was recommended and tested.Results of the experiment indicated that the new technology saved water by 3482~4737 m3/hm2,fertilizer by 19.4%~39.0%,and pesticide by 48.3%,thus increasing the benefit by 18000~25000 yuan/hm2.Besides,it had also created remarkable ecological and societal benefits.
