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。
After many years of plot trial and high-yield demonstration, the number of stem-leaf age of winter wheat before winter was studied. The results showed that the main stem leaf age of winter wheat mainly affected by the sowing time, at the same time by the variety and cultivation conditions. The order of influence of various factors on the leaf age of main stems before winter was sowing time> fertilizer> rarefaction> variety.
