适宜桂南蔗区机械化生产的甘蔗品种筛选研究

对桂糖31号、桂糖42号、桂糖44号、桂糖46号、桂糖47号等5个品种在桂南蔗区全程机械化生产条件下的对比试验,结果表明:蔗茎产量最高的是桂糖46号,其次为桂糖44号;产糖量最高是桂糖46号,其次是桂糖42号;出苗率最高为桂糖42号;发株率最高为桂糖44号;分蘖率最高为桂糖42号;有效茎数最多的是为桂糖46号;含杂率最低的是桂糖46号;损失率最低的是桂糖44号。研究分析各参试品种的农艺性状、工艺性状和适宜机械化情况,从中筛选出桂糖46号和桂糖44号2个适合本蔗区全程机械化生产的甘蔗品种。

Selection of Suitable Sugarcane Varieties for Mechanized Production in Southern Guangxi

Five varieties(Guitang31,Guitang42,Guitang44,Guitang46,Guitang47)of the mechanization of sugarcane in southern Guangxi region were compared in the whole production process experimental.The results showed that the highest cane yield was Guitang46,followed by Guitang44;the highest sugar yield was Guitang46,followed by Guitang42;the best germination was Guitang42;the best ratoon sprouting rate was Guitang44;the best tillering was Guitang42;the most millable stalk was Guitang46;the lowest impurity rate was Guitang46;the lowest loss rate was Guitang44.The agronomic traits,process traits and mechanization characteristics of each tested variety were researched and analyzd.Guitang46 and Guitang44 were suitable for the entire mechanized production in the southern Guangxi sugarcane-planting area.
