在分蘖初期分别用蔗丰灵１／４００、１／５００、１／６００浓度叶面喷施甘蔗中熟种桂糖１５号，几种处理对桂糖１５号整个生长期中＋１叶的叶绿素含量、光合酶ＮＡＤＰ－苹果酸酶都有促进效应。在分蘖初期至拔节初期，几种浓度处理的过氧化物酶活性低于对照，而在甘蔗伸长中期至砍收，则明显高于对照。１／４００浓度处理对桂糖１５号的株高和茎径生长有明显的抑制；１／５００和１／６００浓度处理的能有效促进茎径生长，提高成茎率。最终增产效应是１／６００＞１／５００＞１／４００＞ＣＫ；增糖效应则以１／４００和１／６００为佳。
At the early tillering stage, the sugar cane sugar Guiguang 15 was sprayed on foliage at the concentration of 1 / 400,1 / 500,1 / 600, and the chlorophyll content , Photosynthetic enzyme NADP-malic enzyme has a promoting effect. During the early tillering to early jointing stages, the peroxidase activities of several treatments were lower than those of the control, but were significantly higher than those of the control in the mid-stage of sugarcane elongation. The concentration of 1/400 significantly inhibited the plant height and stem diameter growth of Guiguang 15, and the treatments of 1/500 and 1/600 could effectively promote the stem diameter growth and increase the stem rate. The final yield effect is 1/600> 1/500> 1/400> CK; the effect of adding sugar is 1/400 and 1/600 is better.
