茶树间作巨菌草对茶园小气候及土壤养分的影响

Effects of Tea-Pennisetum sinese Intercropping on Microclimate and Soil Nutrients in Tea Garden

对纯茶园和茶树间作巨菌草茶园的生态环境(小气候因子、土壤因子)和茶树叶片叶绿素含量进行了测定。结果表明,2种不同类型茶园小气候因子(茶园光照强度、空气温度、空气相对湿度)具有显著差异,相对于纯茶园,茶园间作巨菌草能有效降低茶园光照强度和空气温度,提高空气相对湿度,增加土壤养分含量,提高茶树叶片叶绿素含量。说明茶树间作巨菌草可以改善茶园小气候和土壤状况,能够促进茶叶品质的提高。

This experiments were carried out with two modes of tea gardens which were simple tea garden and tea-Pennisetum sinese. intercropping tea garden, and the ecological environment factors of tea gardens(including microclimatic factors and soil factors)and the contents of chlorophyll in tea leaves were determined. The results showed that microclimatic factors had remarkable difference among different modes of tea gardens. Compared with pure tea garden, the intercropping of Pennisetum sinese in tea garden could effectively reduce light intensity and air temperature. Moreover, it could increase air relative humidity, content of soil nutrients and chlorophyll in tea leaves. Tea-Pennisetu sinese intercropping in tea garden can improve microclimate and soil condition of tea garden and promote the improvement of tea quality.
