摘 要: 采取4因素3水平正交试验研究氮肥形态、施用量、施用时期和不同种植行距对甘蔗产量的影响。结果表明:影响最大的是种植行距,其次为尿素形态和追肥时间,尿素施用量影响最小。4因子的最佳组合方案为:在伸长初期每公顷施675kg普通尿素和种植行距为100cm。 The effect of applying urea form, on yield of sugarcane was studied under the o amount rthogonal and time of addition fertilizer and planting row distance design. The results showed that the most mighty factor to cane yield was the row distance, then, the urea form and the time of addition fertilizer, and the last one was the urea amount. The optimal combination plan was the application of 675kg ordinary urea per hectare in the early period of cane elongation and row distance 100 cm.
