摘　　要：通过多年多点的小区试验和高产示范 ,对冬小麦冬前主茎叶龄数进行了研究。结果表明 ,冬小麦主茎叶龄数主要受播种期的影响 ,同时又受品种和栽培条件的制约。各因素对冬前主茎叶龄数影响的大小顺序为播期 >肥水 >稀密 >品种。并对小麦冬前主茎叶龄在生产上的应用进行了研究。The number of main stem leaf age of wheat before winter was studied through small plot experiment and high yield demonstration of many years and many places. The result showed that the number of main stem leaf age of wheat before winter was mainly affected by seeding date, at the same time it was constrained by variety and cultural condition. The order of these effect factors was seeding date > fertilizer and water > density > variety. Moreover its application on the production was studied.
