摘要
连续3a的定位观测和分析结果表明，桕茶间作茶园内影响茶叶产量和品质的小气候条件及土壤条件均得到较大程度的改善和提高。林分结构较纯茶园复杂完善，表现为地上部分和地下部分呈垂直上的成层性和水平上的交错和镶嵌性。因此，对环境好源的利用上，间作茶园较纯茶园充分。间作茶园中茶树的净光合速率较纯茶园高，呼吸速率较纯茶园低，茶树的蒸腾强度也较纯茶园低。因此，间作茶园中茶叶产量和品质具备了优于纯茶园的生理学基础。上述结果表明，桕茶间作模式具有较好的生态学基础。
Observations and measruements in fixed position had been carried out for three years in succession. The results showed: 1)the microclimate factors and soil factors for tea tree were better in mixed tea plantation than in pure tea plantation ; 2)the ecological structure of forest in mixed tea plantation was mor complicated and perfectd than that in pure tea plantation ;3)the ability in using environmental resources was strong in mixed tea plantation.The results also showed that the net photosynthetic rate of tea tree in mixed tea planation was higher,and the respiratory intensity and transpiration rate of tea tree in mixed tea planlation was lower than that in pure tea plan-tation. The results above-mentioned showed that there was better ecological basis in mixed tea plantation.
