乙烯利可以促使茶树花、蕾提早脱落,已被许多试验所证明。我们在1978年第一期曾向读者介绍过这个问题,许多读者问:应用乙烯利进行化学除花后,对第二年茶叶产量的影响如何?是增产还是减产?下面谈谈这个问题。增产效果显著根据1976年浙江省150多个试点证明:在茶树盛花期,喷施600—800ppm乙烯利,一般 Ethephon can promote the tea flower, Lei early fall off, has been proved by many experiments. We introduced this issue to our readers in the first issue of 1978. Many readers asked: How does the application of ethephon to chemical weaning affect the second year’s output of tea, increase or decrease it? Let’s talk about this issue. Significant effect of increasing yield According to more than 150 pilot programs in Zhejiang Province in 1976, it was proved that in the flowering period of tea trees, 600-800 ppm of ethephon was sprayed, generally
