一、前言干旱缺水节约用水、合理用水,使有限的水资源发挥更大的经济效益,已成为发展农业生产的研究课题。1982年以来推广了塑料软管防渗节水措施,取得了显著成效,现在全区塑料管道已发展到750万米,其中软塑管道630万米,共配套机井和机带真空井3.5万眼,手压井6.5万眼,改善和扩大灌溉面积40万亩。 First, the foreword Drought and water shortage Water conservation, rational water use, limited water resources to play more economic benefits, has become the development of agricultural production research topics. Since 1982, the plastic hose seepage control and water saving measures have been promoted and remarkable results have been achieved. At present, the plastic pipe in the whole region has been developed to 7.5 million meters, of which 6.3 million meters are made of soft plastic pipes, with a total of 35,000 vacuum wells , 65,000 hand-killing wells to improve and expand the irrigation area of ​​40 mu.
