间种绿肥模式下茶树光合特征参数的日变化
Diurnal Variation in Photosynthetic Characteristic Parameters of Tea Plant under Intercropping Green Manure Pattern
摘要
Abstract
The diurnal variations in photosynthetic characteristic parameters of tea plant leaves under the patterns of single cropping ( the control) and intercropping green manure ( T1 and T2 ) were studied in tea plantation. The results were obtained as follows: in comparison with the control, the patterns of intercropping green manure significantly increased the chlorophyll a con-tent, net photosynthetic rate, transpiration rate, daily photosynthetic quantity and daily transpiration quantity of tea plant leaves, and reduced the photosynthetically active radiation, leaf temperature and specific leaf weight. The diurnal variations in net photo-synthetic rate and transpiration rate of tea leaves under T1 and T2 all showed a single-peak curve, and the peak value all appeared at 12:00; while those under the control all exhibited a double-peak curve, and the peak value appeared at 10:00 and 16:00, re-spectively. Under intercropping green manure pattern T1( the plant height of intercropped green manure was 135～145 cm) , the photosynthetic characteristic parameters of tea plant leaves had the best performance.关键词
