论新疆可持续农业中化肥的发展方向

农业的持续发展离不开肥料的增产作用 ,有资料表明 ,新疆 195 5— 1997年的化肥施用量与粮食总产量之间的相关系数r=0 .96 1.目前 ,新疆土壤中钾的含量出现明显的入不敷出 ,部分农田出现亏缺。在新疆农业的持续发展中 ,应加强农田养分投入的宏观调控 ,积极发展作物专用复混肥的生产和应用 ,加快新疆对先进技术的引进和研究应用 ,促进新疆农业的可持续发展。

The Development of Fertilizer in Sustained Agriculture in Xinjiang

The sustained development of agricultural depends on the increasing yields of fertilization.Xinjaiang is one of the producive bases of grains,cottons,oil crops and sugar crops.The interrelated coefficient between the total fertilization rates and the total yields of grain is positive significant(r=0.961) from 1955 to 1997in Xinjiang.The Kcontents of soil in Xinjiang decrease continuously.Some fields are shortage.So,for agricultural sustained development in Xinjiang,it is very important that macro-control of fertilization rate of field,the special fertilizer of crops,the precision agriculture and the controlled release fertilizer.
