对近年广西甘蔗研究所选育的桂糖22号、桂引5号、桂糖26号等3个糖能型甘蔗品种进行产量、品质及其主要工农艺性状的研究。结果表明:3个参试品种公顷产蔗量达到能源甘蔗品种120吨以上的技术要求,其中桂引5号产量最高,达171.57吨/公顷,桂糖22号160.90吨/公顷,分别比新台糖22号增产21.7%和14.2%;各品种单位面积可发酵糖量表现与蔗茎产量表现相似,即桂引5号最高,达35.51吨/公顷,其次为桂糖22号,34.75吨/公顷,与对照相比达显著水平。桂引5号、桂糖22号不仅蔗茎产量、单位面积可发酵糖量高,且宿根性强,抗旱,适宜广西旱地甘蔗生产,是理想的糖能兼用品种。
In recent years, Guangxi sugar cane Institute breeding Gui sugar 22, Gui cited 5, Gui sugar No. 26, sugar cane varieties of sugar production, quality, and its main agronomic traits. The results showed that the yield of sugarcane in three tested varieties reached the technical requirement of more than 120 tons for energy sugarcane varieties, of which Guiyin 5 had the highest yield of 171.57 tons / hectare and Guitang 22 160.90 tons / hectare, respectively, 22 yield 21.7% and 14.2%, respectively. The yield of fermentable sugar per unit area of cultivars was similar to that of cane yield, ie Guiying No.5 was the highest, reaching 35.51 t / ha, followed by Guitang 22, 34.75 t / ha, Significantly higher than the control. Gui cited No. 5, Gui Gu 22 not only cane yield, high yield of fermentable sugar per unit area, and strong perennial, drought-resistant, suitable for Guangxi dry land sugar cane production, is the ideal combination of sugar can be used.
