新疆是个干旱地区,发展农牧业生产,工业生产、城镇建设都需要水,但水是有限的,总情况是:供需不平衡,水土不平衡。挖掘水的潜力、提高水的效益,总的不外乎是“开源与节流”。从兵团当前的实际情况看,“开源”是很有限的,而且是投资昂贵,受益很慢。“节流”应该是兵团今后发展水利事业的一个重要途径。实践证明,“节流”是一条投资少,收效快,受益大的一条道路。近几年我们抓了塑膜渠道防渗的“节源”措施,取得了良好的效果,今后还应坚持不懈地抓下去。但这仅是“节流”的一个方面。当前在灌溉用水上的潜力还很大,由于灌溉手段和灌溉方法的落后,灌水量大大超过作物的需水量,既浪费了水,又会导致土壤盐渍化。喷灌是灌溉上的新技术,是“节流”的一项重要措施之一。它用水量少,灌溉质量高,可以节水增产。近几年来国内外喷灌都发展较快,兵团从七十年代后期到八十年 Xinjiang is a dry area. Developing agriculture and animal husbandry production, industrial production and urban construction all require water, but water is limited. The general situation is: imbalance between supply and demand and water and soil imbalance. Excavating the potential of water to improve water efficiency, the total is nothing more than “open source and cut expenditure.” Judging from the current actual situation of the Corps, “open source” is very limited, and it is expensive to invest and has a slow benefit. “Throttle” should be an important way for the Corps to develop water conservancy projects in the future. Practice has proved that “cutting expenditure” is a way of investing less, quickening and benefiting greatly. In recent years, we have grasped the “Dayuan” measures of impermeable plastic film channels and achieved good results. We should persevere in the future. But this is only one aspect of “saving.” The current potential for irrigation water is still high. Due to the lack of irrigation and irrigation methods, the amount of water that is irrigated far exceeds the water requirement of crops, thus wasting water and causing soil salinization. Sprinkler irrigation is a new technology, is “throttling” one of the important measures. It uses less water, high-quality irrigation, you can save water and increase production. In recent years, sprinkler irrigation at home and abroad are developing rapidly, Corps from the late seventies to eighty years
