本文研究了新植蔗不同施肥模式对宿根蔗的后续效应，旨在探讨新植蔗不同施肥模式下，宿根蔗产量和蔗糖分差异及其原因，为进一步优化甘蔗三高施肥模式提供理论依据。试验结果表明，在新植蔗不同施肥模式下，就模式间进行比较，宿根蔗蔗茎产量和收获株数存在显著差异，其规律与新植蔗的结果相一致；宿根蔗的株高在施肥情况下存在显著差异；宿根蔗茎径差异不显著；株高的变异系数存在明显差异，且施肥与否规律相同；生长中后期的叶片Ｎ含量存在明显差异，在施肥情况下差异更加明显；蔗汁锤度无显著差异；叶片Ｐ和Ｋ含量无明显差异。试验结果也表明，在新植蔗不同施肥模式下，宿根蔗施肥比不施肥，蔗茎产量和株数显著增加；叶片含Ｎ、Ｐ、Ｋ量明显增加；株高的变异系数明显较低；而其他性状则无明显的差异。分析试验结果可以看出，新植蔗不同施肥模式下宿根蔗产量的差异主要是由于株数、株高、叶片含氮量、株高整齐度的差异所致，宿根蔗的株数，乃至产量又与新植蔗的有效茎数有密切关系
This paper studied the follow-up effects of different fertilization modes of new sugarcane planting sugarcane on sugarcane, aimed at discussing the differences and reasons of yield and sucrose sugarcane of sugarcane under different fertilization modes in sugarcane planting sugarcane, and providing the theoretical basis for further optimizing sugarcane three-fertilization model. The results showed that under the different fertilization modes of new sugarcane planting sugarcane, there was a significant difference in stem yield and harvested plant number of sugarcane sugarcane with the same pattern as the sugarcane planting sugarcane; There was a significant difference between the two treatments. There was no significant difference in the stem diameter of the peanut cane; the coefficient of variation of the plant height was significantly different and the law of fertilization was the same; the content of N in the middle and late growing stages was significantly different, Brix no significant difference; leaf P and K content no significant difference. The results also showed that in the different fertilization modes of new sugarcane planting sugarcane, the fertilization rate of peanut cane increased significantly compared with no fertilization and the yield and number of cane stem increased significantly. The content of N, P and K in leaves increased obviously and the coefficient of variation of plant height was significantly lower. Other traits no significant difference. Analysis of test results shows that the differences in crop cane yield under different fertilization modes are mainly due to the differences in plant number, plant height, leaf nitrogen content, plant height uniformity, and the number of stubble cane plants, and even the yield The effective number of new sugarcane cane is closely related
