不同种植模式麦田水资源利用率及边际效益分析(Effects of Different Planting Patterns on Water Use Efficiency and Marginal Profits of Winter Wheat)
冬小麦 种植模式 水资源利用率
2010/12/29
选用山东省当前推广面积较大的“20+40”大小行、“20+40”沟播、“20+40”垄作以及常规等行距模式,研究不同种植模式对冬小麦农田水资源利用效率和边际效益的影响。结果表明,等行距、大小行、沟播和垄作种植模式的最大产量分别为7778.6、7624.8、8684.6和8893.7kg/hm2,表明沟播和垄作都具有提高冬小麦产量的潜力,但在获得最大产量时,垄作的蒸散量比沟播提高了76.6mm。...
