摘　　要：试验结果表明:300kg/hm2的底肥对果蔗出苗、株高、茎径、单株重、有效茎、多数商品性状和工艺性状具有正效应,对分蘖、蔗汁抽出率和抗螟性有轻微负效应,故其比不施底肥的增产24.52%,达极显著水平,是本试验中对果蔗效果最佳的底肥用量;600kg/hm2的底肥对果蔗株高、茎径、单株重、部份商品性状、工艺性状和抗螟性有正效应,对出苗无影响,对分蘖、有效茎、多数商品性状有轻微负效应,故其比对照增产20.87%,达极显著水平,是本试验中对果蔗综合性状效果最好的底肥用量;900kg/hm2的底肥对果蔗分蘖、株高、茎径、单株重、有效茎、少数商品性状、工艺性状和抗螟性具有正效应,对出苗、多数商品性状有负效应,故其增产显著,是本试验中对果蔗效果较好的底肥用量;1200kg/hm2的底肥对果蔗分蘖、株高、茎径、单株重、田间锤度有轻微正效应,对其他性状则为负效应,是本试验中效果最差、唯一减产的底肥用量。The result of the experiment showed that basic fertilizer of 300 kg/hm^2 had positive effects on emergence of seedlings, plant height, diameter, weight of single stalk, number of millable canes, most of economical characters and technological characters, but it had slightly negative effects to tillering, per cent of juice and borer resistance. The yield is the highest and 24.52% higher than that without basic fertilizer, and it was extremely outstanding in the experiment. Basic fertilizer of 600 kg/hm^2 had positive effects on the height, diameter, the weight, parts of economical, technological characters and borer resistance but it had slightly negative effects to tillering, number of millable talks and most of economical characters, therefore the yield increased by 20.67% and extremely outstanding. Basic fertilizer of 900 kg/hm^2 had positive effects on tillering, the height, diameter, the weight, the number, a few economic, technological characters and borer resistance, but it had negative effects to emergence of seedlings and most of economical characters. As a result, the yield was increased outstanding. Basic fertilizer of 1200 kg/hm^2 had slightly positive effects on tillering, the height, diameter, the weight and Brix in cane but it had negative effects to others characters, it is the only quantity of basic fertilizer with decreased yield in this experiment.
