不同施肥模式对城口县茶园土壤养分与茶叶品质的影响

为提高城口县茶叶产量、改善茶叶品质和茶园土壤肥力,以茶树品种“福鼎大白茶”为试验材料,设置常规施肥(CK)、茶树专用配方肥(T1)、微生物菌肥和茶树专用配方肥(T2)配施3个处理,对茶叶发芽密度、百芽重、茶叶品质和土壤养分等指标分析,研究不同施肥措施对城口县茶园土壤养分和茶叶品质的影响。试验结果表明,与CK相比T1、T2处理均能提高茶叶发芽密度和百芽重,提升茶叶游离氨基酸、咖啡碱的含量,降低酚氨比,增加茶园土壤pH值、有效磷、碱解氮的含量。T2较T1处理的百芽重有所提高,茶叶游离氨基酸含量提升,咖啡碱和酚氨比下降,土壤碱解氮含量增加。相较三种施肥方式,微生物菌肥和茶树专用配方肥配施能更好地提高茶叶产量和品质,改善茶园土壤环境,可在城口县开展进一步的研究和推广。

Preliminary Report on Application Effects of Slow-release Formula Fertilizer in Tea Plants

In order to accelerate the construction of green production mode for tea in Hubei Province, improve the yield of tea and use efficiency of fertilizers, and improve the quality of tea, application effects of special slow-release formula fertilizer in tea plants were investigated in Wuhan. The results showed that compared with conventional fertilization, application of tea plant-specific slow-release formula fertilizer improved the yield of tea by more than 30%. The amino acid content in tea was increased by 21.05% and 30.82%, respectively, and the income was increased 27 696 （33.88%） and 27 624 （33.79%） yuan/hm2, respectively.
