气候变化对内蒙古马铃薯晚疫病流行的影响

分析内蒙古近几十年气候变化与马铃薯晚疫病流行相关资料,发现,随着全球气候变暖,内蒙古地区6~7月份平均最高、最低气温不断升高,已超过马铃薯晚疫病病原菌侵染发病的适宜温度范围。但是阴雨天的温度和空气相对湿度为马铃薯晚疫病真菌菌丝形成和孢子囊繁殖提供了最佳环境条件。依此建立的内蒙古地区马铃薯晚疫病发生程度的气象预测模型可很好预测其流行规律。

The effects of changing climate on prevalent lating potato epidemic disease in Inner Mongolia

The effects of changing climate on prevalent lating potato epidemic disease of inner mongolia was analyzed.Findings are as follows: as the seven seas warmed up,the average highest and lowest air temperature of June and July were increased continually in inner mongolia.And this temperature exceed the range of fitting temperature of lating potato epidemic disease pathogeny bacterium intrusion.But propagate of this pathogeny bacterium must live in the air of more relative humidity (only in overcast and rainy days it may arrive to this humidity),however,the overcast and rainy environment of inner mongolia provided the conditions of this pathogeny bacterium mycelium come into being and sporangium propagation.According to the results,meteorological prognostic models of lating potato epidemic disease evolvement in inner mongolia were established,and the forcast was perfect.
