Experimental performance of several new sugarcane varieties in Liucheng County

为筛选适宜柳城县蔗区自然栽培条件种植的优良甘蔗新品种,2019年对中蔗福农44号、福农41号、桂糖44号、桂糖55号、云蔗06189这5个引进品种与当地主栽品种桂柳05136(对照)进行1年新植品种比较试验。结果表明:桂糖44号分蘖力强且成茎率高,分蘖率达到198.44%,有效茎数在所有参试品种中最高,达到5297条/667m^2,平均比对照多1575条/667m^2;桂糖44号单产最高,为6.76t/667m^2,比对照增产44.42%;平均蔗糖分为16.41%,比对照高0.5%。福农41号出苗数与分蘖数均优于对照,有效茎数为4148条/667m^2,比对照多555条/667m^2,单产为5.52t/667m^2,比对照增产17.97%,平均蔗糖分为16.03%,比对照高0.12%。试验表现较好的品种为桂糖44号和福农41号,这2个品种适宜在柳城县蔗区推广。

In order to screen the new excellent sugarcane varieties suitable for natural cultivation in Liucheng County sugarcane area.New planting comparative experiment was conducted on five introduced varieties,Zhongzhefunong 44,Funong 41,Guitang 44,Guitang 55 and Yunzhe 06189,with the local main variety Guiliu 05136(control).The results showed that,the tillering rate of Guitang 44 was 198.44%,the tillering ability was strong,and the survival stem rate rate was high.The number of millable stalks was the highest among all the tested varieties,reaching 5297/667m^2,1575/667m^2 more than the control.The yield of Guitang 44 was the highest,which was the 6.76t/667m^2,44.42%higher than that of the control.The average sucrose content of Guitang 44 was16.41%,5%higher than that of the control.The number of seedlings and tillers of Funong 41 were better than that of the control,the number of millable stalks was 4148/667m^2,555/667m^2 more than the control.The yield of Funong 41 was 5.52t/667m^2,17.97%higher than that of the control.The average sucrose content of Funong 41 was16.03%,0.12%higher than the control.The varieties with better planting performance were Guitang 44 and Funong 41,which were suitable for promotion in Liucheng County sugarcane area.
