摘要
[目的]探讨苹果-茶间作对茶树新梢生长状况及产量的影响。[方法]以苹果-茶间作园中的茶树和邻近未间作茶树叶片为研究对象,观测了其在年生长周期中茶树生长状况及茶鲜叶产量的变化情况。[结果]不同季节,间作及对照茶树新梢生长差异较大。春、夏、秋季,间作茶树的冠面温度较对照茶树低,冠面湿度则较对照茶树高,而在冬季,间作茶树的冠面温、湿度均与对照茶树差异不显著;间作茶树的呼吸强度极显著低于对照茶树,净光和强度极显著高于对照茶树,而光和强度的变化无明显规律;间作对茶树新梢发芽密度虽无显著影响,但因其促进茶芽提早萌发、增加了芽叶重量,进而提高了茶鲜叶产量。[结论]为复合生态茶园间作的合理配置和无公害茶叶的生产提供了理论依据。
[ Objective ] The effect of apple-tea intercrop on the growth and yield of tea shoot was studied. [ Method ] Comparing tea leaves in ap- ple-tea intercrop garden with neighboring tea leaves, the change of tea growth and fresh leaves yield in annual growth cycle was observed. [ Re- sult ] There was obvious difference of tea shoot growth in intercropping and control group in various seasons. In spring, summer and autumn,inter- cropping tea had lower canopy temperature and higher canopy humidity compared with control tea,while there was no obvious difference of canopy temperature and humidity in intercropping and control tea in winter;the respiratory intensity of intercropping tea was very significantly lower than that of control tea,and its net photosynthetic intensity was very significantly higher than that of control tea,while there was no obvious change law in photosynthetic rate ;the effect of intercrop on budding density of tea shoot wasn＇ t obvious, but it promoted early germination of tea bud, in- creased leaf weight and improved fresh leaf yield. [ Conclusion ] Our study could provide theoretical foundation for the rational allocation of inter- crop in compound ecological tea garden and the oroduction of non-oolluted tea.
