| 摘 要： | 在硅、镁、硼营养较缺乏的甘蔗田，进行硅肥、镁肥、磷肥的施肥效应试验，结果表明：硅、镁、硼肥及其不同施肥水平对甘蔗的株高、茎径、锤度、产量和产糖量有明显的影响。施用硅肥使甘蔗锤度、产量和理论产糖量分别比对照增加0.42～1．11，11．04～14．96t／hm^2和1．84～2．10t／hm^2；施用镁肥分别比对照增加0.93～1．26，4．02～9．55t／hm^2和0．99～1．53t／hm^2；施用硼肥分别比对照增加0．41～1．20，5．00～10．00t／hm^2和0．80～1．82t／hm^2。

| Abstract: | After the fertilizers of silicon,magnesium,boron were applied in the soil with lower level of available silicon,magnesium and boron,the results indicated there were obvious different effects of silicon,magnesium,boron fertilizer and their different amount on height,diameter,brix,yield and sugar yield of sugarcane.Compared with CK,the brix was increased from 0.42 to 1.11,the yield was increased from 11.04t/hm~2 to 14.96t/ hm~2 and the theoretical sugar yield was increased from 1.84 t/hm~2 to 2.10 t/hm~2 by the silicon fertilizer;the brix was increased from 0.93 to 1.26,the yield was increased from 4.02t/hm~2 to 9.55t/hm~2 and the theoretical sugar yield was increased from 0.99t/hm~2 to 1.53t/hm~2 by the magnesium fertilizer; the brix was increased from 0.41 to 1.20,the yield was increased from 5.00 t/hm~2 to 10.00 t/hm~2 and the theoretical sugar yield was increased from 0.80 t/hm~2 to 1.82 t/hm~2 by the boron fertilizer. |
