摘　　要：研究结果表明:植物龙既能使果蔗显著增产,又能使果蔗增加甘蔗糖分,还能降低蔗茎纤维份而使蔗茎更加泡脆,是唯一可在果蔗生产上单独应用的生长调节剂;稀施美能使果蔗极显著增产、蔗茎纤维份降低而变得更泡脆,但却会使果蔗糖分轻微下降,故其要与植物龙配合施用才可在果蔗生产上应用;硕丰481能使果蔗增产极显著,纤维份含量降低,蔗茎泡度增加,但却会使果蔗糖分明显降低,故其也要与植物龙配合施用才可应用于果蔗生产;喜田宝能使果蔗显著增产,蔗茎泡度增加,但却会使果蔗糖分明显降低,也必须与植物龙配合施用才能在果蔗生产上应用;赤霉素能使果蔗明显增产,蔗茎变泡,但却会使果蔗糖分降低,也必须与植物龙配合施用才可在果蔗生产上应用。Result of the research indicated that Zhiwulong could increase yield and sugar content of garden cane outstandingly. The fibre content of the stalk was reduced, therefore the stalk were softer. It was the only growth regulator that could be used alone in the production for garden cane. Xishimei could increase the yield extremely outstandingly. The fibre content was decreased, therefore the stalk could be softer but sugar content were decreased slightly as a result. It could be used in the production along with Zhiwulong. Shuofeng 481 could increase the yield extremely outstandingly, and the fibre content also decreased, therefore the stalk was softer but sugar content was decreased obviously. It could be used in the production along with Zhiwulong. Xitianbao could increase the yield outstandingly, and soften the stalk, but sugar content was obviously decreased. Therefore it could only be used in the production along with Zhiwulong. GA3 （Gibberellic acid 3） could increase the yield, obviously, the stalk became softer, but it would decrease sugar content. It could only be used in the production along with Zhiwulong.
