摘要
Abstract
In order to solve the problems of water scarcity in Ningxia,high cost in high-lift long-distance water conveyance irrigation area, difficult to maintain the operation and keep lasting benefit by using the traditional channel model of irrigation and the planting structure,the paper analyzed the reasons of irrigate with pipe and drip,through experiments,crop irrigation system and irrigation volume were studied, choosing potato as experimental crop and choosing water-saving irrigation technology and management mode that suitable for Nanchengguaizi main channel's water-saving replenish irrigation area of Gukuo Project as the research object. The result shows that a)compared with spray irrigation,drip irrigation saves water 720 m3 ,increases output 0-7 500 kg,so,drip irrigation is better than spray irrigation. The promotion of water-saving technology is suited to drip irrigation mainly and supplemented by spray irrigation;b)based on the increased treatment to the sediment flow,transferring the land into the“Company + Farmer”intensive management pattern is good.关键词
