【摘要】 针对退耕还林及生态环境建设造成土地资源紧张,水土保持型高效农业发展迅速,土壤侵蚀与灌溉模式落后等问题,该研究通过对延安市安塞县马家沟梯田大棚高效用水系统进行设计,给出了一种梯田大棚水土保持型高效农业用水模式为:梯田大棚雨水直接进入下级橡塑水窖,利用橡塑水窖位置灵活特点滴灌同级梯田大棚内作物。其主要参数为:单位大棚面积需要水窖容积0.13m~3,采用膜下滴灌灌溉方式,灌水定额为11m~3/亩,灌溉次数为8次。初步应用证明,该设施能够减少侵蚀,高效利用水土资源。更多还原

【Abstract】 For returning farmland to forest and the reduction of land resources caused by ecological environment construction,the rapid development of high-efficiency agricultural soil and water conservation,soil erosion and irrigation mode backward such problems,this study presents the mode of high-efficiency agricultural water management in terraces greenhouses by designing the water management system in Majiagou watershed in Ansai County,Yan’an City:the rainwater collected by the terraces greenhouses go directly into the lower rubber cellar,drip crops inside greenhouse at the same level taking advantage of the characteristic of flexible location of rubber cellar.The main parameters of the system are:the cellar volume of unit greenhouse for 0.05m~3,using drip irrigation under plastic film,irrigation quota of 9m~3,irrigation frequency for 4 times.Initial applications show that the facility can reduce erosion and use water and soil resources efficiently.更多还原
