腐植酸可溶性有机肥影响茶叶品质的研究

摘要

目的：研究腐植酸可溶性有机肥对浙江省内不同地区不同茶树品种鲜叶内质成分和品质的影响。方法在杭州西湖区和绍兴兰亭两地，分别对群体种及薮北种进行不同的施肥处理，并采集茶鲜叶测定其内质成分含量。结果相对于对照组，叶面施肥处理可以显著提升茶叶中游离氨基酸的含量，下调酚氨比。结论叶面施肥处理在一定程度上可以提升茶叶品质，具有一定推广使用的价值。%Objective To discuss the influence of soluble humic acid organic fertilizing on tea chemical components and quality.MethodsTwo species Longjing and Soubei (in Xihu district, Hangzhou and Lanting district, Shaoxing, respectively) were fertilized with soluble humic acid by different treating. Then leaves were picked and analyzed for chemical components.ResultsCompared to control, the levels of free amino acids rised significantly with foliage fertilizing, which helped increasing the taste of fresh and brisk.Conclusion Foliage fertilizing can partly increase tea quality, which means soluble humic acid organic fertilizer having the value for application on tea.
