据我所研究,春季田间新梢有虫梢率达20%时为第一高峰始峰期。第一高峰始峰期及持续时期因气象因素的不同而有差异。正确预报第一高峰始峰期及持续期,对指导防治有重要意义。从1978~1988年资料分析,茶小绿叶蝉第一高峰持续时间,随着1~4月份降雨总量增多而延长,说明田间湿度高,有利于茶小绿叶蝉的发育和繁殖;随着1~4月份的日照总时数增加而缩短,说明阴天多,茶小绿叶蝉第一峰期持续时间延长,晴天多,高峰持续期短;
According to my research, there are insect shoots in the field in spring with a shoot rate of 20%, which is the peak of the first peak. The peak and duration of the first peak are different due to different weather factors. Correctly forecasting the peak peak period and the duration of the first peak is of great significance in guiding and controlling the disease. From 1978 to 1988 data analysis, the first green tea leafhopper peak duration, with the increase of rainfall from January to April to extend, indicating high humidity in the field, is conducive to the development and reproduction of green leafhopper; with 1 ~ April sunshine hours increased and shortened, indicating cloudy and more green tea leafhopper duration of the first peak extended, more sunny, peak duration is short;
