甘蔗分蘖期不同阶段喷施蔗丰灵的效果

Effects of zhefengling sprayed in different time of sugarcane tillering stage

分别在甘蔗分蘖初期、盛期、后期 ,用0.17 %浓度的蔗丰灵进行叶面喷施 ,结果3个生育时期处理都能促进甘蔗的生长 ,增加甘蔗茎长、茎径、有效茎数和单茎重 ,从而使甘蔗增产 ,并提高了甘蔗品质。增产效果以分蘖后期喷施为最好,其次为分蘖初期 ,再次为分蘖盛期 ,而增糖效果则以分蘖初期和后期喷施为最佳。

Foliage spray of 0.17% Zhefengling, a highly efficient liquid fertilizer for sugarcane,was applied at the early,middle and late tillering stage of sugarcane,respectively.The results showed that the all Zhefengling treatments promoting the plant growth so increased the stalk leangth,stalk diameter,stalk weight and millable stalks, thus increased the yield of sugarcane. All the Zhefengling treatments increased the sucrose contents both in the cane and juice,and the gravity purity of juice,but decreased the content of reducing sugar in the juice,so the quality of sugarcane improved.The treatment at late tillering stage was the best in the present experiment.
