Manufacturing of the nutrition growth regulator TA-BR preparation liquid and its application to tea

茶树喷施1.5、1.0、0.5μL·L-1TA BR制备液后,叶色浓绿,叶片肥厚,发芽密度明显增大,平均增幅分别为23.01%、15.90%、7.11%,百芽重明显提高,平均增幅分别为13.70%、21.50%、16.20%.TA BR对茶叶内含物也有影响,喷施TA BR制备液后,游离氨基酸和水溶性糖的总量有所升高,而茶多酚和水浸出物含量均有所下降.

When sprayed with 1.5, 1.0, 0.5 μL·L^(-1) of TA-BR prepartion liquid, the color of tea leaves was deep green, the leaves were fleshy, and the bud density was increased significantly in that the average growth rates were 23.01%, 15.90% and 7.11%, respectively. In addition, the weight of 100 buds and shoots was increased by 13.70%, 21.50% and 16.20%, which were higher than CK, respectively. The TA-BR had positive effects on the tea inclusion. The total contents of the amino acids and the soluble sugar increased while that of tea polyhenols and the water extracts of tea decreased.
