摘要： [目的]验证微滴灌高效固态复合肥在新疆高产植棉中的应用效果.[方法]2年内通过在基肥投入量相同条件下,微滴灌高效固态复合肥随水施肥与当地常规施肥,以及微滴灌高效固态复合肥和其它滴灌专用肥四组对比田间试验.[结果]处理1的施肥(微滴灌高效固态复合肥处理)比处理2(常规施肥处理)的棉花叶面积系数增加0.47,单株叶片数增加3.2片/株,棉花干物质重量地上部分增加8.74 g/株,同时地下部分增加0.68 g/株.微滴灌高效固态复合肥比常规施肥降低成本206.11元/hm2,籽棉增加301.8 kg/hm2,净增收益1 023.9元/hm2.微滴灌高效固态复合肥比其它滴灌专用肥增产籽棉341.5 kg/hm2,增加利润1 115.78 元/hm2.[结论]微滴灌高效固态复合肥使棉花增产,农民增效,值得在植棉区大面积推广应用.
