摘　　要：对甜玉米果穗采收后的茎秆含糖量、绿叶数量及含水量测定表明：果穗采收后天数与含糖量之间呈极显著正相关（r＝0．989），与绿叶数量呈极显著负相关（r＝－0．952），与含水量亦是极显著负相关（r＝－0.962）。果穗采收后第5～7天，茎秆含糖量达14％以上，绿叶数量和含水量均适合调制优质青贮饲料。The content of sugar and water, and the number of green leaf of sweet corn stalks were measured after ears were har-vested. The results showed that days after harvest was significantly correlated with sugar content (r=-0. 989),green leaf number (r=-0. 952)and water content (r=0.962)of stalks. When the sugar content of sweat comstalks reached above 14%in five to seven days after harvest,it should be the suitable stage to make quality silage according to the number of green leaves and water content.
