随着农业生产发展需要,自治区化肥的供应量有较大的增长。1980年已达56万吨。施肥技术亦有所改进,主要是氮素化肥改表层撒施为机条施、深层施或全耕层基施,对提高氮肥利用率、增加产量都起到良好效果,如乌鲁木齐县安宁渠公社星火大队,四年来生产实践证明,氮肥全耕层基施比表层撒施,冬小麦可增产两成左右,氮肥利用率比表层撒施可提高10～20％。尽管如此,氮肥损失量仍相当可观,为此,如何合
With the development of agricultural production needs, the supply of fertilizer in the autonomous region has a greater growth. In 1980 it reached 560,000 tons. Fertilization technology has also been improved, mainly nitrogen fertilizer to the surface layering applied as a machine, deep facilities or all-grass-based facilities, to improve nitrogen utilization, increase production have played a good effect, such as Urumqi County, Anningqu commune Spark brigade, production practice over the past four years proved that the top layer of nitrogen fertilizer on the topsoil application, winter wheat yield can be about two percent, nitrogen utilization than the surface layer can be increased by 10 to 20%. In spite of this, the loss of nitrogen fertilizer is still considerable
