夏茶生产的特点是采制时间长,茶树虫害多;茶芽萌发不整齐,无明显“洪峰”出现;更茶茶芽易老化,内含物中茶多酚含量较高,茶汤鲜爽度差,但浓强度较好,耐冲泡。我市夏茶产量约占全年的1/3,特别是出口红碎茶的主要生产季节,针对夏茶特点,切实解决几项技术问题,对完成全年茶叶生产有一定作用。 1 适时防治虫害,安全使用农药夏茶生长期,茶尺蠖开始世代重叠,危害日重。梅雨期,出现小绿叶蝉第一次盛发高峰。伏旱期,各种螨类猖獗。因此,要加强各茶场的虫情测报。根据害虫分布密度、虫龄,确定防治措施。对鳞翅目害虫主要用辛硫磷和菊脂类农药,对叶蝉和螨类主要用乐果等农
The characteristic of summer tea production is that it takes a long time to produce tea and there are many pests of tea trees. Tea buds are irregularly distributed and there is no obvious “flood peak” appearing. Tea tea buds are easy to age, content of tea polyphenols is higher, Strong intensity, resistance to brewing. The output of summer tea in our city accounts for about 1/3 of the whole year, especially the main production season of exporting broken tea. In view of the characteristics of summer tea, several technical problems have been effectively solved, which has a certain effect on the completion of tea production throughout the year. 1 timely control pests, the safe use of pesticides Summer tea growing period, tea scallions began to overlap generations, endangering day by day. Meiyu period, the emergence of the first green leafhopper peak Sheng peak. Volt drought period, all kinds of mites rampant. Therefore, it is necessary to strengthen the detection of insects in tea farms. According to the distribution density of pests, insect age, determine the prevention and treatment measures. Lepidoptera pests mainly with phoxim and chrysanthemum pesticides, the main leafhoppers and mites with dimethoate and other farmers
