摘要： 灰钙土是新疆伊犁河流域重要的土壤资源.察布查尔县有灰钙土15.04×104hm2,其中灌耕灰钙土3.69×104hm2.其肥力特征是:(1)土壤缺氮少磷钾丰富.(2)土壤潜在养分较丰富.(3)灰钙土开垦培肥后,土壤肥力有明显提高,但磷、钾速效养分有下降趋势.(4)土壤缺锌、缺铁,铜丰富.锰、硼丰中有缺.(5)土壤上层养分含量明显高于下层土壤养分含量.培肥途径是:(1)发展农区畜牧业、增施有机肥,实施过腹田培肥土壤.(2)通过多熟立体栽培,增加黄豆、花生、花芸豆等豆类作物茬口,实现既培养地力又增加经济收入双赢目标.(3)推广草田轮作制.有计划安排苜蓿、绿肥、粮食和经济作物裂区轮作.(4)推广平衡施肥技术.
