摘要
为了确定茶树品种的生产布局以及虫害防治的最佳时机,达到以预防为主、将虫害危害程度降至最低的目的,2018年在湄潭县西河乡、湄江镇、石莲乡系统观测了茶树主要虫害发生情况,统计了同期气象要素,对比分析了虫害气象诱因指标。结果表明,当旬平均气温达到17℃、相对湿度为75%时,蓟马开始发生发展;当春季出现高温连晴少雨10d左右、再降至适宜气温20~24℃时,蓟马在短时间内繁殖和暴发;当平均气温在20~26℃、相对湿度为70%~85%时,适宜小绿叶蝉生长;夏季高温干旱对茶树虫害的生存繁殖不利,虫口量减少甚至无虫害发生。
In order to determine the production layout of tea varieties and the best time for pest control,achieve the prevention and control pests in the minimum,the main pests of tea trees were systematically observed in Xihe township,Meijiang town and Shilian Township of Meitan County,the meteorological factors of the same period were statistically analyzed and the meteorological inducement indexes of insect pests were compared in 2018.The results showed that when the ten day average temperature reached 17 ℃,the relative humidity was 75%,the thrips begun to develop;when high temperature and little rain occured for about 10 days in spring,and then dropped to 20~24 ℃,thrips bred and outbroke in a short time;when the average temperature was 20~26 ℃,relative humidity was 70%~85%,which suitable for tea green leafhopper growth;high temperature and drought in summer was detrimental to the survival and reproduction of tea pests,insect populations reduced or even eliminated.
