摘要: 空心菜白锈病流行模型与8个气象因子有关,决定因素是菌量、雨情、雨夜温度和潜育升温。模型由8个子程序组装。本软件可提供后7天发生白锈病指数。短期预测数据,无雨时为零;台风夜温低于23℃,病指数明显上升;梅雨当菌量0.1孢子堆/株时,病指迅速增大。芥蓝霜霉病和一些蔬菜疫病可跟随本模型预测。它的数据可靠,灵敏度高。Abstract: A model related to 8 climatic factors for forecasting white rust disease in Dwamp Morningghgy (DM) was proposed.The determinants are pathogen amount,rainfall,night temperature and effectively accumulative temperature.The model is able to forecast the exponent of lesion will occur in seven days.If there are no rains,the lesion exponent is zero.When the night temperature is less than 23℃ after typhoon,the lesion exponent ascends.While in the season of plum rain and fungi amount is higher than 0.1 stack/plant,the lesion exponent sharply rises.It can also forecast the production of Peranospora and Phytophthora in vegetables with the model and provide reliable and high-sensitive data.
