铜与锌硼钼配施对甘蔗产量和品质的影响

研究了Cu与Zn、B、Mo配施对甘蔗产量和品质的影响,探索微肥对甘蔗增产增糖的有效途径。试验结果表明:Cu、Zn、B、Mo配施甘蔗产量最高,比对照增产27.6%、差异极显著,糖分比对照增加7.36%、差异显著,同时显著增加蔗汁重力纯度;Cu、Mo配施比对照增产16.8%,差异极显著,但对糖分影响不显著。Cu、B配施对甘蔗产量和糖分影响均不显著。Cu、Zn配施产量最差,甚至比不上单施Cu的效果;Cu、B、Mo和Cu、Zn、Mo配施比对照增产14.6%和12.1%,糖分增加8.23%和5.95%,与对照差异显著。Cu、Zn、B配施对甘蔗糖分影响显著,但对增产不显著。在各处理中,Cu、Zn、B、Mo配施是实现甘蔗增产和增糖的最佳组合。

Effects of cuprum fertilizer combined application with zinc, boron,molybdenum on the stem yield and quality of sugarcane

In order to explore the effective way to gain the highest stem yield and best quality of sugarcane,the influence of Cu fertilizer combined application with Zn,B,Mo on the stem yield and quality of ROC22 was researched in this paper.Sugarcane was used as the experimental materials,field plot experiment and different processing was set up to analyze the influence of Cu and Zn,B,Mo fertilizer combined application on the stem yield and quality of ROC22.The result showed as follows,the stem yield was the highest in the treatment that Cu,Zn,B,Mo,four kinds of microelement fertilizer combined,an increase of 27.6% compared with the control,at 1% significant difference level,sugar content was increased by 7.36%,at 5% significant difference level and could effectively raised gravity purity.In the treatments of Cu combined with any one kind of microelement fertilizer of Zn,B,Mo,the yield in the treatment that Cu and Mo combined increased significantly,an increase of 16.8% compared with the control,at 1% significant difference level,but the effects of increased sugar content was not significant.In the treatment that Cu and B combined,the effects of increased all the stem yield and sugar content were not significant.The effect was the worst that Cu and Zn combined,even the stem yield was lower than just using Cu fertilizer.In the treatments of Cu combined with any two kinds of microelement fertilizer of Zn,B,Mo,the effects of increased yield and sugar content in both of the treatments that Cu,B,Mo combined and Cu,Zn,Mo combined were significant,at 5% significant difference level.the stem yield was increased by 14.6% and 12.1% respectively,and sugar content was increased by 8.23% and 5.95% respectively,the effects of increased sugar content in the treatments that Cu,B,Mo combined was significant,but the effects of increased yield was not significant.In each treatment,the effects of both increased stem yield and sugar content were the most significant in the treatment of four kinds of Cu,Zn,B,Mo microelement fertilizer combined.
