3类甘蔗品种成本效益分析

Cost-benefit Analysis of Three Kinds of Sugarcane Varieties

单位面积糖料蔗经济效益主要受气候、土壤、糖料蔗品种等多种因素影响。在无法完全左右气候、土壤等自然因素时,通过改良糖料蔗品种成为我国糖业大省实现糖料蔗增产增收的主要手段之一。文章以云南省耿马县为例,对该地区大面积种植的3类糖料蔗成本效益展开分析,以ROC22为对照组,以云蔗08-1609、云蔗05-49、桂柳05-136为实验组进行收益对比实验。实验表明:与ROC22相比,实验组在农艺性状、单位面积产量及产值、生产成本等方面均更为优异;云蔗08-1609经济效益最佳,其次依次为云蔗05-49、桂柳05-136。

The economic benefits of sugarcane per unit area are mainly affected by climate,soil,sugarcane varieties and other factors.When climate,soil and other natural factors cannot be completely controlled,improving sugarcane varieties has become one of the main means to increase sugarcane yield and income in China's major sugar-industry provinces.Taking Gengma County of Yunnan Province as an example,this paper analyzed the cost-benefit of three kinds of sugarcane planted in large area in this area.ROC22 was used as the control group,and Yunzhe08-1609,Yunzhe05-49 and Guiliu05-136 were used as the experimental groups to carry out the comparative experiment of benefits.The experimental results showed that compared with ROC22,the experimental group was superior in agronomic traits,yield and output value per unit area,production cost,etc.Yunzhe 08-1609 has the best economic benefit,followed by Yunzhe05-49 and Guiliu05-136.
