摘要:
进行了麸酸型有机复混肥在铁观音茶叶上的应用效果试验.结果表明,施用麸酸有机复混肥或配施化肥,其夏、暑、秋三季茶青总产较单施化肥增产1.8%～7.0%,其中以50%有机复混肥+50%硫酸钾复合肥处理产量最高,而3季茶青中以暑茶增产效果最好,较单施化肥增产5.7%～17.6%.与单施化肥相比,施用麸酸有机复混肥提高了暑茶氨基酸总量,尤其是谷氨酸与苯丙氨酸含量,且氨基酸总量总体随麸酸有机复混肥施用比重的增加而增加.综合产量、品质与效益分析,麸酸有机复混肥在茶树上的施肥模式以50%有机复混肥+50%化肥配施最佳.

Abstract:
A field experiment was conducted to study the efficiencies of the compounded organic fertilizer with monosodium glutamate(COFMSG)and when it was applied in conjunction with inorganic fertilizer(IF)for Tieguanyin tea.The results showed:(a)the application of either COFMSG or COFMSG in conjunction with IF increased the total 3 season(summer,mid-summer,autumn)fresh tea yield by 1.8%-7.0%,as compared with IF alone;(b)the highest yield was obtained when 50% of COFMSG and 50% of IF was used;(c)among the 3 seasons,the best fresh tea yield result was shown in the mid-summer with an increase by 5.7%-17.6% over the IF case;(d)the total amino acid content in tea,especially glutamic acid and phenylalanine,increased appreciably with COFMSG fertilizer.Based on the over-all improvement on total amino acid,yield,quantity and economic evaluation,the best fertilizer combination was determined to be half COFMSG and half IF.
