棉花专用缓控释肥和叶面水溶肥应用效果

Study on the Effects of Application of the Controlled-release Fertilizer and Water Soluble Fertilizer Special for Cotton

【目的】研究棉花专用缓控释肥和叶面水溶肥的应用效果。【方法】设置田间小区试验,5个处理,T1:不施肥(CK);T2:常规施肥;T3:常规施肥+叶面水溶肥;T4:棉花专用缓控释肥+叶面水溶肥;T5:棉花专用缓控释肥减量20%+叶面水溶肥,分析不同施肥处理对棉花生育进程、产量构成及产量、经济效益和农学效率的影响。【结果】与常规施肥相比,棉花专用缓控释肥和叶面水溶肥处理生育期没有明显变化,株高有所降低,果枝台数明显增加;棉花专用缓控释肥、叶面水溶肥处理提高了棉花铃数、单铃重而增产;籽棉收入、收益和农学效率均以棉花专用缓控释肥+叶面水溶肥处理最高。【结论】专用缓控释肥和叶面水溶肥配施适合推广应用,是一种省工、增收、增效的施肥模式。

【Objective】 To study the application of cotton special controlled-release fertilizer and water soluble fertilizer in Pishan County, Xinjiang.【Method】 5 treatments were set up in field experiments: T1: no fertilizer(CK);T2: conventional fertilization;T3: conventional fertilization + water soluble fertilizer;T4: cotton special controlled-release fertilizer + water soluble fertilizer;T5: a 20% decrease of cotton controlled-release fertilizer + water soluble fertilizer. After this, the effects of different fertilization treatments on cotton growth, yield components and yield, economic benefits and agronomic efficiency were analyzed.【Result】 Compared with conventional fertilization, the growth period of cotton treated with special controlled-release fertilizer and water soluble fertilizer had no obvious change, the plant height decreased, and the number of branches increased significantly. Cotton special controlled-release fertilization and water soluble fertilizer treatments increased the number of bolls and the boll weight, also the yield was increased. The income and agronomic efficiency of cotton controlled-release fertilizer + water soluble fertilizer treatments were the highest among these treatments.【Conclusion】 The application of cotton special controlled-release fertilizer and water soluble fertilizer are suitable for local popularization in local area. It is a kind of fertilization mode of saving labor, increasing income and increasing efficiency.
