摘要
蔗甘多宝(SR4)叶面喷施台糖172和桂糖11号及SR8喷施桂糖8号5~6周后均比对照显著增加甘蔗蔗糖份,分别平均达1.83%(绝对值,下同),2.43%和2.07%;并增加蔗汁纯度,降低还原糖份,增加甘蔗产量;蔗甘多宝还有增加宿根苗数的趋势。
Applications of theganduobao (SR4) on the foliar surface of sugarcane varieties F172 and CGX 11 5 to 6 weeks before harvest gave the sucrose contents in sugarcane stalks of 13. 79% and 13. 10% , the juice purities of 88. 51% and 79. 41% respectively, as compared with the sucrose contents of 11. 96% and 10. 67%, the juice purities of 85. 95% and 76, 69% respectively in untreated controls. Treatment to the foliar surface of sugarcane variety CGX 8 with SR8 6 weeks before harvest, the sucrose content and the juice purity of stalks were 14. 27% and 88. 30%, as compared with 12. 20% and 85. 89% in untreated controls. Also, Zheganduobao decreased the reducing sugars in the juice of sugarcane stalks, increased the cane weights and was harmless for the ratoon regrowth.
