【摘要】 在安徽省黄山地区的红壤上,研究了茶园种植乌桕树对改善小气候环境的效应。夏秋季借助乌桕树稀疏的林冠为茶树遮荫,茶树-乌桕间植茶园的太阳总辐射低于茶树的光饱和点,其散射辐射比普通纯茶园增加,散射辐射与直接辐射的比率高达0.78-0.90,气温及湿度得到调节,宜于茶树正常生长;茶树及乌桕树的根系分别从浅层及深层吸收土壤水分,提高了土壤水的利用率。因此,茶园间植乌桕可减轻夏季热旱危害茶树生长,提高茶叶产量和品质,是江南茶区生产优质绿茶的一种人工生态模式。更多还原

【Abstract】 The effect of interplanting tallow trees in tea plantations on microclimatic environment were studied on red soils of Huangshan region, Anhui Province. Tallow trees could appropriately shade the tea trees with the aid of their sparse canopies in summer and autumn. In tea-tallow tree interpiantation, the total solar radiation is lower than the light saturation point of tea trees and the diffuse radiation of is higher than that of pure tea plantation.The ratio of diffuse radiation to direct radiation is 0.78—0.90. The temperature and humidity are regulated and adapted to the growth of tea plant. The roots of tea and tallow trees are able to take water from upper and deep soil layers respectively, and the utilization rate of soil water is increased. Therefore, interplanting tallow trees in tea plantations could keep tea trees from the harm of hot and dry weather in summer and increase the yield and quality of tea. It is suggested that tea-tallow interplantation is an artificial ecological pattern producing green teas of high quality in tea planting area.更多还原
