湖北省地处北纬29°—33°,东经108°—116°地理范围内。历年种植小麦2千万亩左右,山区占30%上下,70%的面积分布在平原地区。八十年代以来,随着条锈病生理小种的变化,感病品种面积逐步上升到80%以上,成为我国南方麦区主要流行区域之一。在预测病害流行方面,经过近几年的探索,逐步明确外来菌量、元月气象、早春病情是我省长期预测的基本依据。1.春季流行程度与甘肃省菌源越夏区大面积感病品种种植区域的小麦秋苗病情高度相关。我省条锈病菌源问题,经过1983年以来
Hubei Province is located at latitude 29 ° -33 ° north and longitude 108 ° -116 ° east. Over the years planted about 2 million mu of wheat, mountain up and down 30%, 70% of the area is located in the plains. Since the 1980s, with the change of physiological races of stripe rust, the area of susceptible cultivars has gradually risen to more than 80%, becoming one of the major epidemic areas in southern China. In the prediction of disease epidemic, after several years of exploration, and gradually clear the amount of foreign bacteria, the first month of meteorology, early spring condition is the basis for long-term prediction of our province. 1. The degree of spring epidemic is highly correlated with the disease of wheat autumn seedlings in large area susceptible cultivars in Gansu Province. Rusty rust source in our province, after 1983
