甘蔗增糖增产剂试验结果

The Results of Cane-sugar Promoter Experiment in Sugarcane

１９９３年９月下旬至１０月中旬，采用广西农业大学研制、生产的甘蔗增糖增产剂在对旱地和水田蔗的５个品种进行试验，喷药后４０～９０ｄ测定１３个点的甘蔗蔗糖分，平均比对照提高１．３０％（绝对值），甘蔗产量增加５８５０ｋｇ／ｈｍ２；８月份和９月份追施氮肥的甘蔗增糖增产较显著，甘蔗蔗糖分提高１．６９％（绝对值），增产１０３５１．５ｋｇ／ｈｍ２；８月份和９月份不追肥的甘蔗．喷施增糖增产剂的效果相对较差。平均来说，糖厂增利２５８２．２５元／ｈｍ２，农民增收８１９元／ｈｍ２。

Five sugarcane varieties were employed to conduct the experiment of spraying cane-sucrose promoter, produced by Guangxi Agricultural University, from late September to early October, 1993, in 13 upland and lowland fields.From 40 to 90 days after treatment,the sucrose content in cane and cane yield in the treatment with cane-sucrose promoter were 1.30% (absolute value) and 5 850 kg/hm2 higher than those in the control, respectively. The increases were more significant when nitrogen fertilizer was applied in August or early September. In these cases, the sucrose content in cane and cane yield in the treatment with cane-sucrose promoter were 1. 69% (absolute value )and 10 351. 5 kg/hm2 higher than those in the control, respectively.In average, the benefits earlied by mills and peasants increased 2 582. 25 yuan/hm2 and 819 yuan/hm2, respectively, from the application of cane-sucrose promoter.
