有机肥替代化肥技术推广模式与效果评价

基于"果菜茶有机肥替代化肥"项目试点区实地调研数据,采用定量分析与案例分析相结合的方法,分析有机肥替代化肥技术推广模式与实施效果.结果表明:"配肥方案+肥料产品"推广模式限定农户可选择的补贴肥产品,由于给定的补贴肥产品并不为农户所熟悉,农户未按照推荐方案施肥,推动有机肥替代化肥的效果有限;"供肥企业+配额管理"推广模式...

Extension Mode and Effect Evaluation of OrganicFertilizer Substituting Chemical Fertilizer Technology#br#

Based on the survey data in the pilot area of organic fertilizer substituting chemical fertilizer in apple planting project, this paper analyzed the promotion pattern and implementation effect of organic fertilizer substituting chemical fertilizer technology (OSCT) by the method of quantitative analysis and case analysis. The results showed that the promotion pattern of “fertilizer combination scheme & fertilizer products” limited the choice of fertilizer products as subsidized fertilizers. Farmers did not follow the recommended program for fertilization because the fertilizer products with subsidy were not familiar to them. The pattern had limited effect in promoting OSCT. The other pattern of “fertilizer supply enterprises & quota management” limited fertilizer companies that could supply subsidized fertilizers. The pattern was conducive to relax the choice of fertilizer products and obtained remarkable effect in promoting OSCT. So, more flexible promotion pattern was better adopted in OSCT. Currently there were some problems in OSCT promotion, such as the mismatch between technological supply and demand, the overlook of farmers′ demand for stable production and income increase in the policy objective constitution, and the oversimplification of the effect evaluation in process of policy implementation. The suggestions were proposed for improving the flexibility and feasibility of policy in OSCT promotion, such as reducing the purchase restrictions on alternative fertilizers, propelling the addition of organic fertilizer and reduction of chemical fertilizer step-by-step and evaluating the implementation effect of OSCT policy by a more comprehensive way.
