通过绿色诱盘测定迁飞着落蚜虫动态来研究迁飞传毒蚜虫与烟草黄瓜花叶病毒病株率日变化率的关系 ,在概率分析与统计拟合分析的基础上 ,提出了蚜传烟草花叶病具时滞的田间病株日增长率与烟蚜关系模型—— PHYCMV模型 .利用该模型对湖南的 3个地点进行模型拟合检验 ,平均准确率在 90 %以上 .该模型的建立 ,可以通过当时田间的有翅蚜量和田间病株率来预测 12d之后田间病株率的增加值 .
The relationship between the aphid migrating aphids and the rate of change of tobacco cucumber mosaic virus was studied by measuring the dynamics of aphids moving off by green trap. On the basis of probability analysis and statistical fitting analysis, Phyllostachys pubescens phytophthora infestans (Phylloxera) disease model with phyto-phytopathic mycorrhizal (PHYMIV) model was developed based on the phytoremediation of phytoplankton The increase in field strain rate after 12 days can be predicted from the amount of winged aphid in the field at that time and the field strain rate.
