摘要
[目的]探讨栗茶间作与覆草对茶园生长环境和茶叶品质的影响.[方法]通过栗茶间作、覆草试验,调查相应的环境气候、土壤情况,观察茶树芽叶生长状况,比较茶样相关品质成分.[结果]栗茶间作降低了风速和光照强度,提高了环境温度、湿度;覆草提高了土壤有机质及有效N、P、K的含量,减少了水土流失,增加了土壤含水量,提高了冬季地温;栗茶间作、覆草均增加了水浸出物、茶多酚、氨基酸、咖啡碱含量,降低了酚/氨比.[结论]栗茶间作、覆草可以有效地调节茶树生长环境,改善土壤状况,调节茶叶酚/氨比,有利于茶叶品质的形成.
Abstract
[Objective] To discuss the effect of intercropping and covering straw on tea garden environment and the quality of tea.[Method] By test of chestnut-tea intercropping and covering straw,we investigated the corresponding environmental climate and soil conditions,observed the tea tree growth status,and compared the difference of related quality components.[Result] Chestnut-tea intercropping reduced the wind speed and illumination intensity,improved the environment temperature and humidity.Covering straw played the role of improving the content of the organic matter and N,P,K in the soil,reduced water and soil loss,increased soil moisture content,improved the ground temperature in winter.The aqueous extract,tea polyphenol,caffeine,amino acid had different degrees of improvement,and reduced ratio of polyphenols and amino acids.[Conclusion] Chestnut-tea intercropping,covering straw can effectively adjust the tea tree growth environment,improve soil condidon,and adjust the ratio of tea polyphends to amino.All that are beneficial to the formation of tea quality.
