广增素（802）A型是桂林市临桂综合化工厂生产的植物生长调节剂,近年来应用于粮油、果蔬等增产较明显。为探索其对茶树的效应,1992年6～9月在我场科研室和五大队布点试验。经观察,应用广增素的茶树长势良好,芽叶肥嫩,取得较好的经济效益,现总结如下: 一、材料与方法 选择有代表性的、管理相同、茶树生长状况相似的试验茶园。供试品种为云南大叶种,树龄25年,年产量属中上水平。试验3次重复,喷水对照,施用广增素前将茶树蓬面的嫩梢采下,按茶青采摘标准和留叶要求采净,使基本一致。科研室点喷施广素为100ppm,每次亩用30克,兑水60公斤;五大队点为50ppm（亩15克）。早上露水干后喷药,以喷湿蓬面的叶面叶背为度。药后6小时内遇雨补喷,月喷2次,6～9月共7次。茶园用药后,当芽长至1芽3～4叶时进行采摘,留1张
Guangsheng Su (802) A is a plant growth regulator produced by Lingui Comprehensive Chemical Plant in Guilin City. In recent years, it has been applied to grain and oil production more obviously. In order to explore its effect on the tea tree, from June to September 1992 in our field research room and the Fifth Brigade distribution test. It has been observed that the widely used tea plants grow well and the buds are tender and fertile. The economic benefits obtained are as follows: I. Materials and Methods The representative tea plantations with the same management and similar growth status were selected. Test varieties for the Yunnan big leaf species, age 25 years, the annual output is in the upper level. The test was repeated 3 times, water spray control, before the application of widely proliferated tea tree Pengmian tender shoots taken, according to Cha Qing picking standards and leaves required mining net, so basically the same. Research Institute point spray Shi Su as 100ppm, with 30 grams per mu, watered 60 kilograms; five battalion point of 50ppm (15 acres of m). Morning dew dry spray, to spray the surface of the leaves of the wet Pu Peng for the degree. Within 6 hours after the drug case of rain fill spray, spray 2 times, 6 to 9 months a total of 7 times. Tea garden medication, when the bud grows to 1 bud 3 to 4 leaves for picking, leaving 1
