摘  要:
1997年做了田间试验用来评价影响马铃薯晚疫病流行的关键天气条件。在Reckenholz做了 2个试验研究晚疫病的潜伏期和侵染速率。结果表明 ,当累计有效积温达到 2 34 6 5℃·h时 ,孢子囊开始在马铃薯叶片出现。温度是影响晚疫病流行的重要因子。病害侵染的重要条件是温度超过 10℃并且在连续 6h内空气相对湿度大于 90 %。降雨在病害传播中发挥了重要作用。根据PhytoPRE和CWC两个决策支持系统所采取的病害防治取得了较好的病害防治效果

摘  要:
Field trials were conducted in 1997 to evaluate crucial weather conditions for potato late blight epidemic.Two trials were performed to prove latent periods on different varieties and infection rate at Reckenholz.Sporangia were found on the leaflets if the accumulated temperature was above 2,346 5 degree hours in the potato. Temperature is a very important factor for the epidemic of disease. The key condition for disease infection was a temperature over 10℃ and relative humidity of more than 90% in successive 6 hours. Rainfall played an important role for disease dispersal. Better disease controls were received by following PhytoPRE and CWC model in field trials.
