我团位于天山南麓焉耆盆地,全团8万亩耕地,其中五分之一面积程度不同地遭受苏打盐渍化危害,严重地影响农作物产量的提高。近年来,大搞农田基本建设,大力发展綠肥,轮种苜蓿,采用拉砂压碱、客土深耕、增施有机肥料以及施用石膏、磷肥等综合改良措施,收到初步成效。为了广泛地探索改良苏打盐渍土的有效措施,一九七五和一九七六年,我们在苏打盐渍土上进行了种稻施用风化煤的试验,初步证实风化煤具有良好的改土增产作用。 My regiment is located in the Yanqi basin in the south of Tianshan Mountains. The whole group of 80,000 mu of cultivated land, of which one fifth of the area affected by different levels of soda salinization, seriously affecting the improvement of crop yields. In recent years, vigorously promote farmland infrastructure, vigorously develop green manure, rotation alfalfa, the use of pull sand pressure base, guest deep plowing, increasing organic fertilizer and the application of gypsum, phosphate and other comprehensive improvement measures, received initial results. In order to extensively explore effective measures to improve soda saline soils, we conducted a pilot study on paddy weathered coal in soda saline soil in 1975 and 1976, initially confirming that weathered coal has a good soil amendment Increase production.
