摘要
测土配方施肥技术是我国正在推广的一项环境友好型技术。本文基于2011年江苏省稻农微观调研数据,利用随机前沿分析方法(SFA)探讨测土配方施肥技术对种植技术效率的影响。研究表明:稻农采用测土配方施肥技术有利于水稻种植技术效率的提高,该结论为测土配方施肥技术长期推广提供了政策依据。同时,户主为男性、教育年限和水稻商品率对技术效率有显著正向影响,家庭非农收入比例和受灾率对技术效率有显著负向影响。
The formula fertilization technology by soil testing is an environmentally friendly technology in China.With the rice farmers′ survey data in Jiangsu Province in 2011,this paper analyzed the effect of formula fertilization technology on the technical efficiency,by using the stochastic frontier analysis（SFA） method.The conclusions were as follows.The formula fertilization technology had a significantly positive effect on technical efficiency of rice cultivation,which could serve as a basis for the policy-making on the extension of this technology.At the same time,the male household head,length of education and rice commodity rate had significant positive effects on technical efficiency,while the proportion of non-agricultural income and disaster-affected area ratio had significant negative impacts on it.
