不同新型水溶肥料对茶叶的增产效果及经济效益分析

Analysis on the Effects of New Water Soluble Fertilizers on Tea Production and Economic Benefits

[目的]探讨不同类型新型水溶肥料在云南茶叶生产上的应用效果,筛选出适合云南茶叶生产应用的新型水溶肥料。[方法]选用6种新型水溶肥料对供试品种云抗10号产量、品质、生化成分及经济效益进行研究,筛选出对该品种具有增产作用的新型水溶肥料。[结果]从产量性状与生化成分角度看,以喷施微量元素水溶肥料、含腐植酸水溶肥料、含氨基酸水溶肥料等效果较好,其中以微量元素水溶肥料增产效果最好,增产10.66%;从对茶叶品质影响和经济效益分析角度看,喷施含腐植酸水溶肥料的茶叶品质综合表现较好,较对照增加收入12 153.55元/hm2,产投比为30.0∶1。[结论]综合产量、品质和经济效益三方面的效果,建议茶叶生产上推荐使用含腐植酸水溶肥料、含氨基酸水溶肥料、微量元素水溶肥料等较好。

[Objective] The application effect of new water soluble fertilizer was studied. And the suitable fertilizer was selected. [Method] the author evaluated 6 kinds of new water soluble fertilizer＇ effects on tea production and economic benefits. [Result] From the aspect of output anti biological （omposition, microelement water soluble Drtilizer, humic acid water soluble fertilizer and amino acid water soluble fertilizer are reconunended, of which microelement water soluble fertilizer is of the best effect and can increase production by 10.66% compared with juxtaposes; from the aspect of tea quality and economic benefits, humic acid water soluble tertilizer works best and can help increase benefits by 12 153.55 Yuan/hm^2 and the value to cost ratio is 30.0：1. [Conclusion] Microelement water soluble fertilizer, humic acid water soluble fertilizer and amino acid water soluble fertilizer are recommended to use in tea production considering output, quality and economic benefits.
