茶树生殖器官的生长,大量地消耗了营养物质,致使茶树新梢生长减弱。控制采叶茶园的生殖生长,减少花果对养分的消耗是增产茶叶的一项有效措施。用乙烯利诱导茶树落花落果试验指出:在茶树盛花期用乙烯利疏花疏果,疏花效果可达80—93%。乙烯利疏花后,结果率明显下降,喷一次的效果可达36—38%,喷二次的效果可达75%。乙烯利疏花疏果后, The growth of tea tree reproductive organs, consumption of nutrients in large quantities, resulting in tea shoot growth weakened. Controlling the reproductive growth of tea plantation leaves, reducing the consumption of nutrients for floral fruit is an effective measure to increase tea production. With ethephon tea flower fall and fall test led to that: the flowering of tea with thinning thinning ethephon, thinning effect of up to 80-93%. After ethephon thinning, the result rate dropped significantly, the effect of spray once up to 36-38%, spray twice the effect of up to 75%. Ethephon thinning thinning fruit,
