香蕉控释配方肥技术进步贡献率研究——以广西产区为例

Study on Technology Progress Contribution Rate of Controlled Release Fertilizer for Banana:A Case Study of Guangxi Region

该文通过了解新型控释配方肥技术在广西香蕉种植过程中的使用情况,结合在广西获取的技术采用户和未采用户的家庭、生产、技术以及投入产出数据,利用要素替代弹性法测算控释配方肥采用的技术进步贡献率。研究结果表明:采用户较未采用户的技术进步贡献率高约13.47%;新增肥料和农药的投入对产出的提高有较大作用,且技术采用者所表现出来的贡献度更高。因此,控释配方肥技术的使用在香蕉生产中的技术贡献,优于传统施肥技术。

Through understanding using of the new controlled-release fertilizer technology in Guangxi banana plant- ing process and combing with technology users and no users＂ production, technology and input -output data in Guangxi, this paper calculated technology progress contribution of using controlled release fertilizer by means of factor substitution elasticity method.The results show that users＂ technology progress contribution rate is about 13.47%, higher than non users, this result is mainly due to income gaps between two different groups; the increase of fertilizers and pesticides input will have a greater effect on the output increase, and the technology users＂ contribution is higher than non users, it strongly suggest that technology contribution of using controlled release fertilizer is better than traditional fertilization technique in banana production.
