新疆地区的农地,极大多数位于荒漠或半荒漠境内.在很干旱的地区内进行农业生产.灌溉水是一个最主要的自然条件.据最近了解.该区耕地的灌溉水量,基本上是够用的;不论在地区平衡和季节平衡上,都没有多大问题.剩下的只是工程的配套、工程质量的提高、维护管理的加强、灌溉技术的提高,以及如何节约投资、劳力、用水等问题.主要矛盾解决以后,如何改良和防止很多耕地的次生盐渍化问题就突出了.十余年来,新疆的许多生产和研究单位,用了不少精力,不懈地解决这个问题,虽然取得了不少显著成效,但是还没有完全得到解决.今后还须继续进行顽强的斗争,才能获得全胜.新疆地区的耕地,除少数土壤条件较好外,绝大多数是从盐渍土、盐土或容易返盐的荒漠土开垦出来的.这些土地如果改良得好,往往是高产田.但是由于改造得不彻底或曾一度改良了,后
Most of the agricultural land in Xinjiang is located in desert or semi-desert areas. Agricultural production occurs in very arid areas. Irrigation water is one of the most important natural conditions and it has recently been learned that the amount of irrigation water in the arable land in this area is basically Sufficient enough; there is not much problem in terms of regional balance and seasonal balance, but what is left is only the matching of projects, the improvement of engineering quality, the strengthening of management and maintenance, the improvement of irrigation technology and how to save investment, labor, water, etc. After the solution of the main contradictions, how to improve and prevent the secondary salinization of cultivated land has been highlighted. For more than a decade, many production and research units in Xinjiang have spent a lot of effort to solve this problem tirelessly, though Has achieved a lot of remarkable results, but has not been completely resolved in the future but also to continue tenacious struggle in order to obtain victory.Accompany of arable land in Xinjiang, with a few good soil conditions, the vast majority are from saline soil, Salty or easily returnable saline desert soil reclaimed from the land if improved, often is a high yield field.But due to the transformation is not complete or has been improved after
