为了有效地防治棉叶蝉,促进华南棉花发展,研究了10个陆地棉品种田间棉叶蝉数与温度、降水的关系,建立了11个陆地棉棉叶蝉数量气象条件预报模型,其中3个分别可以较准确地预报抗虫棉95-1、石家庄428 2个品种和10品种平均单株棉叶蝉数。品种间棉叶蝉发生轻重对温度、降水的反应不同,为了提高预报精确度,每个品种应各建立一个棉叶蝉预报模型。
In order to effectively control cotton leafhopper and promote the development of cotton in southern China, the relationship between cotton leafhopper number and temperature and precipitation in 10 cotton cultivars was studied, and the meteorological condition prediction models of cotton leafhopper in 11 cotton fields were established. Among them, 3 Respectively, we can predict the average number of cotton leafhopper per plant of two varieties of insect-resistant cotton 95-1, Shijiazhuang 428 and 10 varieties more accurately. The occurrence of cotton leafhopper severity varies with temperature and precipitation. In order to improve the forecast accuracy, a cotton leafhopper forecasting model should be established for each variety.
