Measures to prevent tea trees from blooming
In summer and autumn every year, tea trees not only have tea buds and flower buds in the same year, but also have fruits developed and matured last year, forming the phenomenon of "carrying a baby", which affects the yield and quality of Ding Xianye. In order to improve the yield and quality of tea, the measures to prevent tea from blooming are introduced as follows: 1. Spray gibberellin. During the peak period of physiological differentiation of flower buds, gibberellin 100 mg / kg per mu plus 2% urea aqueous solution 75% 100 kg was sprayed evenly on the front of the leaves. Gibberellin can stimulate the elongation and division of primordial cells in tea buds.

Ways to deal with the flowering of tea trees
Yu Huaijiong, Guihua Village, Yuping Town, Hongya County, wrote that: at present, a large number of local tea trees blossom and bear fruit, consuming tea nutrients and affecting tea production in the coming year. Ask what pollution-free pesticides can be used to remove flowers and fruits from tea trees to ensure a bumper tea harvest in the coming year. Liao Changli, an expert on tea cultivation in Pujiang County, replied: the climate was hot and dry in the early stage of this year, and Rain Water increased in the later period, resulting in stagnant water in some low-lying areas with poor drainage, and the recent warm winter, and three factors led to the blossom and fruit of tea trees in some parts of our province. This phenomenon is bound to affect the output of tea next year.
