本文依据小麦印度腥黑穗病菌的生物学特性，及世界各主要小麦产区的地理气候资料，利用地理信息系统对该病菌的适生性进行了研究。结果表明，小麦印度腥黑穗病菌适生气候条件为：大于零度以上的有效积温≥１３００日度；１年中最冷月的平均温度≤２０℃；小麦抽穗扬花期间的平均温度为７℃～２９℃，平均大气相对湿度≥４８％。
Based on the biological characteristics of wheat head Indian Sturdy Headworm (Triticum aestivum L.) and the geographical and climatic data of the major wheat producing regions in the world, this paper studied the suitability of this pathogen by using geographic information system (GIS). The results showed that the suitable climatic conditions of wheat head Indian Sturdy Headworm were as follows: the effective accumulated temperature above zero is ≥ 1300 days; the average temperature of the coldest month in 1 year is ≤20 ℃; the average temperature during flowering of wheat is 7 ℃ ~ 29 ℃, the average relative humidity of the atmosphere ≥ 48%.
