LI Ji-hui · Anhui nongye kexue · 2008
[Objective] The research aimed to study the prediction model of the aphis in cotton in Xinjiang and provide accurately service for the prevention and cure of aphis disserve in time.[Method] According to the data of aphis disserve stages such as beginning,fastigium,subsidise phase and disserve intensity,combining with weather condition data as temperature,humidity,rainfall,sunlight and accumulate temperature in the same period,the mathematical statistic analysis was made.[Result] The statistics was set up for different stage of aphis disserve,and model and inquire service also be executed.[Conclusion] The prediction model is accurately,and prevention and cure is efficiently.
