查询词典 plant factor

The result of correlation analysis is as follows, the series of Sitobion avenae of emergence size and period correlate with temperature, precipitation, a sum of heat and a sum of rain. Weather state factor of temperature-precipitation can be used to forecased the population of Sitobion avenae. A problem of risk probability can be settled by the grade series of calculation and stochastic simulation, order transfer of Markov chain, so table of risk value of cantemperature, precipitation and Sitobion avenae.are list This is a new approach about PRA in plant protection.

相关分析的结果是麦长管蚜发生量和发生期等级序列与温度、降水量等级序列及积温、积雨值密切相关，通过温度-降水量天气相关状态因子可以预测有害生物的发生状况；通过随机模拟风险因子各个序列和马尔柯夫链状态转移概率的计算，得出了有害生物风险分析和预测过程中较难估算的风险概率，并计算出了北京市温度、降水量和麦长管蚜不同等级的发生风险值表，这在植保有害生物风险分析的方法上是一种新的探索。
