一、盐碱地造林的意义 新疆地域辽阔,也是我国土壤盐渍化最重的省区。在近3亿亩可垦荒地中,盐碱地占60％以上,新疆目前4800万亩耕地中,不同程度的盐渍化土壤就有1700万亩,有的是开垦前原有的,有的则是开垦后次生的,土壤盐渍化影响作物的生长,产量很低,严重的颗粒无收,甚至被迫弃耕,成为不毛之地。生态环境恶化,有的还处于积盐状态,土壤次生盐渍化还在发展。兵团农一师十团现有种植面积在五万八千亩,受盐碱危害面积达二分之一。兵团农七师123团,全部弃耕的盐碱地就达四、五万亩,成为发展农业生产极为不利的因素。
First, the significance of saline-alkali afforestation Xinjiang vast territory, but also China’s most salty soil salinization provinces and autonomous regions. In nearly 300 million acres of reclamation and wasteland, saline-alkali land accounts for more than 60% of Xinjiang’s current 4800 acres of arable land, varying degrees of salinization of soil there are 1700 acres, some before the reclamation of the original, while others are reclaimed Health, soil salinization affect crop growth, yield is low, serious crop failure, and even forced to abandon farming, become barren. The ecological environment is deteriorating, and some are still in salt accumulation. Soil secondary salinization is still developing. Corps Nongyishi division ten existing planted area of 58,000 acres, harmed by the salt area of up to one half. Corps 123 division of agricultural seven divisions, all abandoned saline land to four or five acres, become the development of agricultural production is extremely unfavorable factors.
