茶稻间作系统叶面积指数高于单作茶园，且上、下２ 层空间分布合理，水稻生长前期形成上部茶冠和下部水稻的生态边界层，生长后期则形成上部水稻和下部茶冠的生态边界层，有利于系统对光、热、水、气资源的充分利用．比之于单作茶园，茶稻间作系统内盛夏期相对光强减弱３５７ ％ ，午后温度降低０９ ～１９ ℃，相对湿度增加７ ％ ，为茶树生长提供了较适宜的生态环境条件，新梢生长速率有所提高．茶稻间作系统中的水稻比水田水稻水分利用率高，边际效应显著，有效穗数增加，结实率提高 The leaf area index of tea-rice intercropping system was higher than that of monoculture tea plantation, and the upper and lower two layers were distributed rationally. The ecological boundary layer of upper tea crown and lower rice formed at the early stage of rice growth, and the upper rice and lower tea crown The boundary layer is conducive to the full utilization of light, heat, water and gas resources by the system. Compared with the single tea plantation, the relative light intensity of the intercropping system of rice-rice intercropping system decreased by 35.7% in the summer, decreased by 0.9-1.9 ° C in the afternoon and increased by 7% in relative humidity, which provided a more suitable ecological environment for tea plant growth Environmental conditions, shoot growth rate has increased. The paddy rice in rice-tea intercropping system had higher water use efficiency than rice in paddy field, significant marginal effect, increased effective spike number and enhanced seed setting rate
