本文对14～15年生湿地松与茶树间作茶园和单作茶园的研究表明:间作茶园光强减弱45.2～38.6％,气温低1～3 ℃,昼夜温差小,空气湿度夏季有明显提高;土壤养分含量,0～20cm土层内有降低趋势,20～60cm稍有提高;茶树叶片的净光合效率提高4％左右,蒸腾强度降低20.3～21.7％;叶片上表皮、栅状组织和全叶均较薄,叶质柔嫩,茶叶产量平均提高 8％左右;茶叶中的咖啡碱、氨基酸含量较高,酚、氨比值低,绿茶品质较好;林木蓄积量为3.3m~3/亩,综合经济效益可提高30％左右。
The study on intercropping wetland and tea tree between tea plantations and tea gardens for 14-15 years showed that the light intensity of intercropping tea plantation was reduced by 45.2-38.6%, the temperature was 1-3 ℃, the temperature difference between day and night was small, and the air humidity was significantly increased in summer. Soil nutrient Content in 0 ~ 20cm soil layer decreased slightly, while 20 ~ 60cm increased slightly. The net photosynthetic efficiency of tea leaves increased about 4% and the transpiration intensity decreased by 20.3 ~ 21.7%. The upper epidermis, Thin, soft leaf, tea yield increased by about 8% on average; caffeine in tea, amino acid content is higher, phenol, ammonia ratio is low, green tea quality is better; forest stock volume 3.3m ~ 3 / acre, comprehensive economic benefits Increase about 30%.
