| 摘 要： | 以新台糖22号(ROC22)为试材,以不施氮肥为对照,设T1(尿素5 g/盆作基肥1次施用)、T2(尿素作基肥2.5 g/盆和分蘖肥2.5 g/盆2次施用)及T3(尿素作基肥1.5 g/盆、分蘖肥1.5 g/盆和攻茎肥2 g/盆3次施用)3个处理,研究了氮肥不同施用次数对甘蔗干物质积累、产量及品质的影响。结果表明,随氮肥施用次数的增加,甘蔗干物质积累量、产量及产糖量显著增加,但蔗糖分含量略有下降;氮肥不同施用次数对甘蔗各器官、各生长阶段干物质积累的影响有明显差异。 |

| Abstract: | To take no nitrogen fertilizer as the control,three treatments were desiged with equal amount nitrogen of 5g 15N-labeled urea/pot but applied in 1,2 and 3 splits respectively,to study the effects of application times of nitrogen fertilizer on dry matter accumulation,yield and quality in sugarcane varieties ROC22.T1 received 1 split which whole nitrogen of 5g/pot was applied at sowing time;T2 received 2 splits which 2.5g /pot nitrogen at sowing time and 2.5g/pot at tillering stage,respectively;T3 received 3 ... |
