本文用MaxEnt软件对小麦印度腥黑穗病(Karnal bunt)在我国的潜在分布进行了预测。结果表明,小麦印度腥黑穗病在中国适生范围广。根据适生值的大小,中风险区和高风险区主要分布在我国华北、黄淮海、西南、西北、长江中下游和东北地区的小麦主产区,加强这些区域的调查监测和检疫对保护我国的小麦生产有重要意义。
Karnal bunt caused by Tilletia indica Mitra, was an important quarantine disease of wheat in the world. The potential risks of this disease in China were analyzed by using MaxEnt software. The results indicated that Karnal bunt has large suitable areas in China. Zones of moderate and high risk covered northern China, Plain of Yellow River and Huaihe River, southwestern China, northwestern China, northeastern China, middle and lower Plain of Yangtze River. The main areas of wheat are planted in these regions. It is therefore necessary to quarantine and monitor Karnal bunt in China.
