一、品种选用 长江中下游地区地理生态条件多样,各地推广小麦品种类型存在明显差异。因此,如何因地制宜选用优良品种是夺取小麦高产优质的一项重要措施。该区小麦生育期间降雨量较多,且分布不均,小麦生育后期湿害严重,光照不足,主栽品种应以春性早熟为主,对纹枯病、白粉病、赤霉病、穗发芽具有较好的抗性。其中,江苏沿江、江淮麦区、安徽省江淮中部应选用红皮软质小麦品种,如宁麦9号、扬麦9号等;而在安徽省沿淮地区、河南南部应以白皮软质小麦为主,如皖麦48等。
First, the selection of varieties The geographical conditions of the Yangtze River in the lower reaches of diverse geographical areas, popularization of wheat varieties across the obvious differences. Therefore, how to select good varieties according to local conditions is an important measure to seize the high yield and quality of wheat. During the growth period of wheat in this area, there was more rainfall and uneven distribution, and the wet injury of wheat in later period was very serious and the light was insufficient. The main cultivars should be mainly of spring precocious pheasants, and should be sensitive to sheath blight, powdery mildew, scab, Has good resistance. Among them, the Yangtze River in Jiangsu, the Yangtze River Huaihe District, Jianghuai in Anhui Province should use soft red wheat varieties, such as Ningmai 9, Yangmai 9, etc .; and in Anhui Province along the Huaihe River in southern Henan should be soft white Wheat-based, such as Wan Mai 48.
