| 摘 要： | 以新台糖22(ROC22)为试验材料,研究了氮肥不同施用方法对甘蔗干物质积累、产量及品质的影响.结果表明,与对照比较,施用氮肥可极显著提高甘蔗干物质积累量、蔗茎产量、产糖量,显著提高蔗糖含量；随氮肥施用次数的增加,甘蔗干物质积累量、蔗茎产量及产糖量显著增加,但蔗糖含量略有下降；氮肥不同施用方法对甘蔗各器官、各生长阶段干物质积累的影响有明显差异.

| Abstract: | Taking no nitrogen fertilizer as the control,three treatments with equal amount of 15N-labeled urea were designed to study the effects of application times of nitrogen fertilizer on dry matter accumulation,yield and quality of sugarcane varieties ROC22.The results showed that with the increasing of nitrogen fertilizer application times,dry matter accumulation,stalk yield and sugar yield of sugarcane increased significantly,while sucrose content in sugarcane stalk decreased slightly.The effect of application times of nitrogen fertilizer on dry matter accumulation in organs and at the growth stages of sugarcane was significant. |
