春玉米不同种植模式农田水分利用效率的研究
- Title:
- Water Use Efficiency of Different Planting Pattern of Spring Maize
- Keywords:
- spring maize; planting pattern; water use efficiency
- 摘要:
- 研究了甘肃河西走廊地区春玉米在不同种植模式下的干物质积累动态、籽粒产量、经济效益和能量产出各指标及相应的农田水分利用效率WUE.春玉米不同种植模式,对光、热、水、肥的利用效率有一定的影响,导致其干物质积累、籽粒产量和能量产出的差异.研究表明:春玉米与马铃薯间作模式的籽粒产量和经济产量效率均最高,春玉米与小麦套种模式的能量产出效率最高.河西走廊灌溉区节水高效种植模式首先应是春王米与马铃薯间作、春玉米与小麦套种,其次为春玉米与黄豆间作.
- Abstract:
- Some characteristic of different planting pattern of spring maize,such as the accumulation of dry matter,the yield of seed,the economic efficiency,the energy output and their water use efficiency,are researched.Different planting pattern of spring maize affects its use efficiency of sun light,heat,water and fertilizer,which leads to divergence of its accumulation of dry matter,yield of seed,the economic efficiency and the energy output.According to farm experiment,it is certain that the pattern of intercropping spring maize with potato produced the highest yield of seed and the highest economic efficiency,the pattern of interplanting spring maize with spring wheat produced the highest energy output.As a result,the high efficiency and saving water pattern of spring maize,first is that of intercropping spring maize with potato,second is that of interplanting spring maize with spring wheat,third is that of intercropping spring maize with soyabean in the irrigation area of Hexi Corridor in Gansu province.
