| 摘要: |
| 目的 蔬菜作物不合理施肥和过量施用化肥，不仅影响作物产量与品质提升，还带来资源浪费，影响农田生态环境。推进蔬菜有机肥替代化肥技术意义重大，文章以期为蔬菜种植户对有机肥替代化肥技术推广、激励农户积极参与投资绿色农资提供重要的科学依据。方法 基于北京市、山东省和安徽省的4个县（区）328户设施蔬菜种植户调研数据，通过构建二元Logistic和Tobit回归模型分别对有机肥替代化肥施用技术蔬菜种植户的支付意愿和支付意愿价值进行分析。结果 78.7%的受访蔬菜种植户对有机肥部分替代化肥技术具有支付意愿，且支付意愿价值平均值为E（WTP）=31.51元/667m2。农户学历、蔬菜种植收入占比、有机肥替代后蔬菜售价、施肥配套设施和接受过科学施肥指导对农户的支付意愿有显著影响。农户蔬菜种植收入占比、家庭劳动力人数、对有机肥替代化肥技术改善生产环境的认知、对有机肥替代化肥技术后蔬菜品质的认知、有机肥替代后蔬菜售价和接受过科学施肥指导对农户的支付意愿价值有显著影响。结论 技术带来的利润增加与相关技术指导对蔬菜种植农户采用有机肥替代化肥技术具有重要的影响。提出了推进设施蔬菜有机肥替代化肥技术实施的加强政策宣传、完善产业扶持、强化精准服务、抓好生产配套等建议措施。 |

| Abstract: |
| Unreasonable fertilization and excessive application of chemical fertilizer in vegetable crops not only affect the improvement of crop yield and quality, but also result in waste of resources and risk of farmland environment pollution. It is of great significance to promote the technology extension of partial substitution for chemical fertilizer by organic fertilizer （PSCFOF） in vegetable crops.The purpose of this study is to provide an important scientific basis for spreading the technology of PSCFOF and encouraging farmers to actively participate in the investment of green agricultural materials. Binary Logistic model and Tobit model were used to analyze the willingness to pay tor the organic fertilizer based on the survey data of 328 vegetable farmers in four counties from Beijing, Shandong and Anhui province. Results showed that 78.7% of the surveyed vegetable farmers had significant WTP for the technology of PSCFOF and the average value of WTP was about 31.51 RMB / 666.7 m2. Farmers' education background, the proportion of vegetable planting income in total family income, the price of vegetables, fertilization facilities and scientific guidance of fertilization had significant impacts on Farmers' WTP for the technology of PSCFOF. The proportion of farmers' vegetable planting income, the number of family labor force, the knowledge of PSCFOF in improving environment and vegetable quality, the price of vegetables after using the technology of PSCFOF, and scientific fertilization guidance had significant effects on the value of WTP. It is concluded that the increase of profit and related technical guidance significantly affect WTP of vegetable farmers for adapting the technology of PSCFOF. Some policy suggestions are put forward to promote technology of PSCFOF, including strengthening policy propaganda, improving industry support, strengthening precise service and improving production supporting facilities. |
