塔里木河垦区,是我师粮棉生产的两大基地,土壤盐渍化程度较为严重.为了保证农作物正常生育,就应针对当地土壤水分及土壤含盐量结合气温等生产因子,因地制宜灌溉,以调节各生产因子间的矛盾而达到丰产.根据1959年的调查研究结果指明,要满足作物各生育期对土壤水分的要求,必须就作物的外在表现、气温及土壤盐分的变动,适当安排灌溉的间隔天数.灌溉水量的大小,除应保证土壤水分满足作物需要外,还要防止盐分回升.
Tarim River reclamation area, is the division of grain and cotton production of two major bases, the degree of soil salinization is more serious.In order to ensure the normal crop growth, it should be for the local soil moisture and soil salinity combined with temperature and other production factors, irrigated according to local conditions to Adjust the contradiction between production factors and achieve high yield.According to the 1959 survey results indicate that to meet the crop growth of the soil moisture requirements, the crop’s external manifestations, temperature and soil salt changes, appropriate arrangements for irrigation Of the number of days of irrigation.The size of irrigation water, in addition to ensure that the soil moisture to meet the needs of crops, but also to prevent salt rise.
