糖料蔗新品种农艺性状及产量的比较

Comparation of Agronomic Traits and Yield among Sugarcane Varieties

以糖料蔗绿色高产、高糖、高效为目标,以桂糖49号、桂糖42号、福农41号、桂糖43号、桂柳05136等5个优良新品种与新台糖22号(对照)为参试品种,采取小区试验与大田示范(表证试验)相结合的评价方法。小区试验结果表明,在广西来宾地区具有推广价值的糖料蔗优良新品种为桂柳05136、福农41号和桂糖49号,其理论产蔗量分别比对照新台糖22号增产9.07、7.40和5.99t/hm2,分别提高10.31%、8.41%和6.81%;理论产糖量分别比对照新台糖22号增产1.34、1.28和0.88t/hm2,分别提高11.02%、10.53%和7.24%。大田示范(表证试验)结果表明,桂柳05136、福农41号和桂糖49号的理论产蔗量和理论产糖量均显著高于对照新台糖22号,桂柳05136、福农41号的蔗糖分显著高于对照新台糖22号,这与小区试验结果相吻合。

Five varieties of Guitang 49, Guitang 42, Funong 41, Guitang 43, Guiliu 05136 and Xintaitang 22(asthe control) were selected as materials to achieve high yield, high sugar content and great efficiency.The evaluationmethod combined with the plot experiment with the field demonstration was adopted. The result of the plot experimentshowed that in the Guangxi Laibin area, the sugarcane varieties with commercial value were Guiliu 05136, Guitang 41 and Guitang 49. The yield of the sugarcane varieties of Guitang 49, Guitang 41 and Guiliu 05136 increased by 9.07,7.40 and 5.99 t/hm2(increased by 10.31%, 8.41% and 6.81%), respectively than that of the control Xintaitang 22;thetheoretical sugar yield increased by 1.34, 1.28 and 0.88 t/hm2(11.02%, 10.53% and 7.24%), respectively, comparedwith that of Xintaitang 22. The theoretical sugarcane yield and sugar content of Guiliu 05136, Funong 41 and Guitang49 were significantly higher than those of Xintaitang 22, and the sucrose contents of Guiliu 05136 and Funong 41 weresignificantly higher than that of Xintaitang 22. This coincides with the results of the plot test.
