随着我区农业生产的发展与化肥工业的兴起,化肥施用量日益增多:1986年化肥施用量为92万吨,1987年近100万吨,亩施用量平均已达23.4公斤。在交通沿线的农村与国营农场,化肥施用量增长更快,对农作物产量的提高起到了良好的促进作用。但据近几年调查,农村和农场自实行联产承包责任制以后,有相当一部分农户或承包组只重视施用化肥,忽视有机肥,更不重视种植绿肥。有关统计资料表明,全疆种植绿肥面积1986年比1985年减少了56.07万亩,苜蓿与绿肥面积只占耕地面积10％左右。1987年仍在继续减少,施农家肥面积约占耕地面积30％以下。
With the development of agricultural production and the rise of fertilizer industry in our district, the application of chemical fertilizers is increasing day by day. In 1986, the amount of chemical fertilizer was 920,000 tons and in 1987 nearly one million tons. The average amount of mu has reached 23.4 kg. In rural areas and state-owned farms along the traffic routes, the amount of chemical fertilizer increased more rapidly and played a good role in promoting crop yield. However, according to recent surveys, since the implementation of the system of contract responsibility for removals by farmers and farms in rural areas and farms, a considerable number of farmers or contracting groups only emphasize the application of chemical fertilizers while neglecting organic fertilizers and less emphasis on planting green manure. Statistics show that the area of planting green manure in Xinjiang decreased by 606.07 hectares in 1986 compared with 1985, while that of alfalfa and green manure only accounted for about 10 percent of the cultivated land. In 1987, the number of farmland manure still occupied about 30% of the cultivated area.
