甘蔗新品种在贵州高产创建及吨糖田中的性状表现

Character Performance of New Sugarcane Varieties in Demonstration Fields for High Sugarcane Yield and High Sugar Yield

为加快甘蔗新品种在贵州的推广应用,选用甘蔗新品种黔糖4号、黔糖06-212、桂糖96/211、桂糖96/154、桂糖00/122、新台糖22号、新台糖21号、新台糖25号、赣蔗18号等9个新品种为示范对象,以桂糖11号为对照(CK)进行了高产创建和吨糖田示范。结果表明:高产创建及吨糖田示范甘蔗新品种均表现好,在坝地,9个新品种的平均产量为144.15t/hm2,产糖量20.00t/hm2,种植利润26 872元/hm2,加工业税内利润16 465元/hm2,分别比CK增加12.8%、37.5%、30.8%和16 787元;在坡地,9个新品种的平均产量为115.34t/hm2,产糖量15.75t/hm2,种植利润16 004元/hm2,加工业税内利润12 082元/hm2,分别比CK增加19.9%、42.0%、83.2%和11 818元。

Nine new sugarcane varieties of Qiantang 4,Qiantang 06-212,Guitang 96/211,Guitang 96/154,Guitang 00/122,Xintaitang 22,Xintaitang 21,Xintaitang 25,Gantang 18 and Guitang 11（CK）were tested in demonstration fields for high sugarcane yield and high sugar yield to speed up popularization and application of new sugarcane varieties in Guizhou.The results showed that the average sugarcane yield,sugar yield,panting profit and pretax profit of nine new sugarcane varieties planted in flat land are144.15t/hm^2,20.00t/hm^2,26 872Yuan/hm^2 and 16 465Yuan/hm^2,12.8%,37.5%,30.8% and 16 787 Yuan higher than CK respectively.The average sugarcane yield,sugar yield,panting profit and pretax profit of nine new sugarcane varieties planted in slope land are 115.34t/hm^2,15.75t/hm^2,16 004Yuan/hm^2 and 12 082Yuan/hm^2,19.9%,42.0%,83.2% and 11 818 Yuan higher than CK separately.
