本试验是于1976—78年间,在哥印拜陀甘蔗育种研究所的农场中进行,以研究5种不同下种量(即每公顷种植90,000、135,000、180,000、270,000和360,000芽)对3个甘蔗品种(即 Co658、Co419以及 Co6304)生产性能和产量潜力的影响。结果表明 Co6304的新植蔗和宿根蔗每公顷的产量及最终的商品蔗糖都是最高的,而 Co658的则最低。早熟品种Co658不仅是新植蔗而且是宿根蔗在株龄10个月和12个月时的商品蔗糖份都较其他两个品种的为高。由于 Co6304的产量潜力较大,因而每公顷的产糖量也最高。在 Tamil Nadu 的条件下,除每公顷下种量最少的90,000芽外,其他几种不同下种量的甘蔗产量和商品蔗糖都无显著差异;下种量最少的新植蔗产量显著地低于其他下种量的。但在宿根蔗中,显然是由于分蘖较多而消除了这种差异。
This experiment was conducted from 1976 to 1978 at the farm of the Coimbatore Sugarcane Breeding Institute to study the effects of 5 different species (ie 90,000, 135,000, 180,000, 270,000 and 360,000 buds per hectare) on 3 The effects of sugarcane varieties (ie Co658, Co419 and Co6304) on their performance and yield potential. The results showed that the yield per hectare and the final commercial sugar of Co6304 were the highest, while Co658 was the lowest. The precocious cultivar Co658 is not only the new sugarcane but also the sugarcane of the commercial sugarcane of the ratoon cane at the age of 10 and 12 months of age than the other two cultivars. As Co6304 production potential is greater, so the yield of sugar per hectare is also the highest. Under the conditions of Tamil Nadu, no significant differences were found in the yield of sugar cane and commercial sugar except for 90,000 buds per hectare; the yield of new sugarcane with the lowest yield was significantly lower than Other under the kind of. However, in ratoon sugarcane, it is clear that this difference is eliminated due to more tillers.
