哈密市气候干燥,降雨稀少,年平均降水量仅为33毫米,蒸发量却高达3100毫米,水资源十分匮乏,未开垦地的开发利用完全取决于与境内有限的水资源利用率高低。因此只有大力发展高科技节水农业,充分利用有限的水资源,哈密的农业生产才能腾飞。喷灌、滴灌、微灌、CN灌等多种灌溉形式并举。现把南戈壁盐碱地滴灌棉花情况介绍如下。1998年1月,哈密开发区聘请 Hami City, arid climate, rare rainfall, the average annual rainfall of only 33 mm, but the evaporation is as high as 3100 mm, water resources are scarce, the development and utilization of uncultivated land depends entirely on the limited use of water resources in the territory. Therefore, only by vigorously developing high-tech water-saving agriculture and making full use of the limited water resources can Hami’s agricultural production take off. Sprinkler irrigation, drip irrigation, micro-irrigation, CN irrigation and other forms of irrigation simultaneously. Now the South Gobi saline drip irrigation cotton situation is as follows.
