氨基酸菌肥施用量对茶树生长及土壤肥力的影响

为探究不同氨基酸菌肥施用量对茶树生长和土壤肥力含量的影响，以鸿雁12号茶树为研究对象，采用田间微区试验的方法，设置了不施用氨基酸菌肥作对照组(CK)和氨基酸菌肥施用量分别为75 kg·hm^-2(T1)、150 kg·hm^-2(T2)、225 kg·hm^-2(T3)和300 kg·hm^-2(T4)的处理，研究不同氨基酸菌肥施用量对茶树生长、茶叶品质及土壤肥力的影响。结果表明：氨基酸菌肥施用后能显著增加茶叶芽头密度及茶叶产量，提高茶叶中氨基酸含量和土壤中碱解氮含量。试验6个月后与CK相比，T4组的芽头密度显著增加了63.4%,茶叶产量显著增加了71.5%;T1～T4处理茶叶中氨基酸含量分别增加了9.73%、6.41%、7.57%和13.2%,土壤中碱解氮含量分别增加了25.0%、36.0%、46.0%和37.6%。综上，氨基酸菌肥的施用能提高茶叶产量及品质，改善茶园土壤环境质量，为茶园生产的合理施肥及优质高效生产提供数据参考。

Effects of amino acid bacterial fertilizer on tea plant growth and soil nutrients

To explore the effects of amino acid fertilizer on the growth of tea plant and soil fertility,by planting Hongyan 12 tea tree,we conducted a field micro plot experiment including following treatments:no fertilization(CK),75 kg·hm^-2 amino acid bacterial fertilizer(T1),150 kg·hm^-2 amino acid bacterial fertilizer(T2),225 kg·hm^-2 amino acid bacterial fertilizer(T3),and 300 kg·hm^-2 amino acid bacterial fertilizer(T4).The effects of different application rates of amino acid bacterial fertilizer on tea growth,tea quality and soil nutrients were analyzed.The results showed that the application of amino acid bacterial fertilizer would significantly increase the tea bud density and yield.The content of amino acids in tea and the content of alkali hydrolyzable nitrogen in soil were also increased.After 6 months,compared with CK,the T4 treatment significantly increased the bud head density by 63.4%,and the tea yield by 71.5%.The tea amino acid content in T1~T4 treatment increased by 9.73%,6.41%,7.57%and 13.2%respectively,and the soil alkali hydrolyzable nitrogen content increased by 25.0%,36.0%,46.0%and 37.6%respectively.The application of amino acid bacteria fertilizer increased the yield and quality of tea,improved the soil environmental quality of tea garden,which provided data reference for reasonable fertilization and efficient production of tea garden.
