黄土高原农业调水增产技术浅析

Techniques of redistributing water and increasing yield on Loess Plateau

  • 摘要: 黄土高原地区水资源严重缺乏,大部分地区年降雨量为250~600mm,地表水平均径流量为136.91 亿m3,人均484.58m3,仅为全国人均水平的1/3。阐述了黄土高原地区农业调水技术发展状况以及培肥地力以肥调水、轮作倒茬调水、抗旱育种调水、间隙休闲调水、径流农业调水、节水灌溉农业调水和化学技术调水增产技术的作用,为黄土高原发展节水型农业提供理论依据。

     

    Abstract: Based upon the fact that rainfall is 250~600mm,run off 13.7 billion cubic meter,water resource 484.58m3 per person on Loess Plateau,several redistributing water measures including the building up fertilizer, ratation cropping,drought-resistant breeding,intermittent fallow,run-off agriculture,irrigation and chemical techniques were expounded.It provides a theoretical basis for the development of water-saving agriculture.
