生物黄腐酸肥料在茶叶上的应用研究

Application Study Biological Fulvic Acid Fertilizer on Tea

施用嘉有黄腐酸水溶肥料可提高茶叶产量、增加经济效益。对比常规施肥,亩增施嘉有黄腐酸水溶肥料20 kg,春茶亩增产14.5 kg,增幅为21%;夏秋茶亩增产21.2 kg,增幅为8.1%,亩净增收1485.8元,增幅13.6%;底肥常规化肥减量5%、15%条件下,产量与常规施肥产量持平。

The yield and economic benefit increased by applying Jiayou fulvic acid water-soluble fertilizer. Com- pared with regular fertilization, applying 20 kg Jiayou fulvic acid water-soluble fertilizer could increase yield 14.5 kg per 667 m2 for spring tea and 21.2 kg for summer and autumn tea, the rate of growth respectively was 21%, 8.1%. The net income was 1485.8 yuan, the growth was 13.6%. The yield had no significant change when reducing dosage of regu- lar fertilizer by 5% and 15%.
