微滴灌高效固态复合肥在新疆高产植棉中的应用效果初探

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.

Primary Discussion on the Effects of Micro Drip-irrigation High-efficient Compound Solid Fertilizer Applied to High-yielding Cotton Planting in Xinjiang

【Objective】The main purpose of this study was to indentify the effects of micro drip-irrigation high-efficient compound solid fertilizer applied to high-yielding cotton planting in Xinjiang.【Method】The compative test was conducted among the four groups including:micro drip irrigation high-efficient compound solid fertilizer applied with water,the local common appication of fertilizer,micro drip irrigation high-efficient compound solid fertilizer and other drip-irrigation special fertilizer.【Result】The coefficient of cotton leaf area of treatment 1(Micro drip irrigation high-efficient compound solid fertilizer)were increased by 0.47,compared with the treatment 2(Common application of fertilizer),the number of leaf per plant were increased by 3.2 leaf/plant.Aboveground dry matter weight of cotton plant were increased by 8.74 g/plant.Subsurface matter were increased by 0.68 g/plant.The cost of mico drip-irrigation high-efficient compound solid fertilizer were reduced by 206.11 yuan per ha.compared with common application of fertilizer.Seed cotton were increased by 301.8 kg/hm2.The net income was increased by 1 023.9 yuan/hm2.The seed cotton from micro dripirrigation high-efficient compound solid fertilizer were 341.5 kg/hm2 more than that from other drip irrigation special fertilizer.The profit was increased by 1 115.78 yuan/hm2.【Conclusion】The test indicated that micro drip irrigation high-efficient compound solid fertilizer could help make cotton yield increase,which is worth being popularized in large area.
