阿克苏河流域灌区灌溉水利用效益的研究

Research of Irrigation Water Usage Benefit in Irrigation Area of Akesu River Basin

我国水资源紧缺,建设节水型社会丝毫不能懈怠。自上世纪80年代以来我国的节水已有明显成效,但我国农业是用水大国,新时期面临的水资源形势更加严峻,农业的干旱缺水呈现愈来愈严重的态势。在调研及试验的基础上,通过对阿克苏河流域典型农田小区、试验区、典型分区调研与分析,科学地总结出灌区作物水分生产率与灌溉效益的关系,得出灌区主要农作物的最佳灌溉水量和灌溉次数,为实现高效、节水的农业生产提供科学依据。

In China, water resources are absent and it can＇ t be rest to construct a water - saving society. Our country has got- ten obvious effect on water - saving since the 80＇ s of last century, however, a plenty of water needs to be used in Chinese ag- riculture, and the sitnation of water resources becomes serious increasingly with severe deterioration of agricultural drought and water shortage in the new period. Based on the research and experiments, by researching and analyzing the typical farudand, experimental zone and typical area in the Akesu river basin, the relation between the productive rate of moisture and irrigation benefit of crops in the irrigation area was concluded scientifically to obtain the optimum irrigation water quantity and irrigation times of the main crops in the irrigation area so as to supply scientific accordance for realizing the agricultural production with water saving and high performance.
