摘　　要：研究了亚热带丘陵红壤泡桐茶树复合种植模式的综合效果。结果表明 :与纯茶园相比 ,泡桐茶树复合园的日平均光照强度下降 5 1 .2 % ;茶蓬内日平均气温下降 0 .3～ 1 .2℃ ;相对湿度增加 6.1～ 7.5个百分点 ;1m土层内根系总量增加 44 .4% ;各土层贮水量提高 2 .5 %～ 1 1 .3 % ;凋落物增加 2 8.0 2 % ;凋落物养分含量增加 2 0 .3 % ;0～60cm土层内速效氮、磷、钾总量增加 3 4.6% ;茶叶产量提高 1 6.9% ;The synthetic effects of “paulownia-tea” intercropping system in hilly red soil in subtropical region were studied. The results showed that in comparison with pure tea garden, in “paulownia-tea” intercropping garden, the daily average light intensity was decreased by 51.2%; the daily average atmospheric temperature in tea bush was 0.3～1.2℃ lower; the average relative humidity was increased by 6.1～7.5 percent; the dry weight of root system in 0～1m soil layer, the water-holding capacity of 0～1m soil layer, the weight and nutrient content of fallen substance, the total content of readily available N, P and K in 0～60cm soil layer, as well as the tea yield were increased by 44.4%, 2.5%～11.3%,28.02%,20.3%,34.6% and 16.9% respectively, there was an improvement in tea quality.
