摘要:

目的: 本文系统研究了测土配方施肥技术对经济林化肥施用的影响,以及参与培训对农户测土配方施肥技术采用的影响机制与差异,旨在于探索推广测土配方施肥技术的有效方法。方法: 在理论分析的基础上,利用2018年对浙江省10县314个经济林经营户的调查数据,采用倾向匹配得分法(PSM)进行了实证分析。结果: 研究结果显示,测土配方施肥技术通过补充土壤养分信息和化肥质量信息显著减少农户化肥施用约271.65 kg·hm-2,培训通过增加技术信息显著提高农户测土配方施肥技术采用的概率15%,但不同培训方式的效果存在显著差异。具体来看,专业培训可以显著增加农户测土配方施肥技术采用概率10%;强信任的培训主体能有效传播技术信息,但在控制主体偏好时,培训效果被弱化;“理论与实践指导”“理论自学”的培训方式均能帮助农户掌握技术信息,且在控制方式偏好时,培训仍然有效果。结论: 测土配方施肥技术可以降低经济林化肥施用量,而培训能缓解农户测土配方施肥技术采用过程中信息掌握不足的问题。在未来经济林化学品投入减量化过程中,需要兼顾技术推广以及在此过程中的信息传递,以促进绿色生产。

Abstract:

Objective: In this paper we investigated the effect of soil testing and formula fertilization technology on the application of chemical fertilizer in economic forest, and further analyzed the mechanism and different impact of farmers' training on the adoption of soil testing and formula fertilization technology, in order to explore effective method to promote soil testing and formula fertilization technology. Method: Based on theoretical analyses, and the survey data from 314 farmers in 10 counties of Zhejiang Province in 2018, an empirical analysis was conducted with the method of Propensity Score Matching (PSM). Result: Result showed that soil testing and formula fertilization technology significantly reduced the application of chemical fertilizer about 271.65 kg·hm-2, with the supplement of soil nutrient and chemical fertilizer quality information. The training significantly improved the adoption of soil testing and formula fertilization technology by 15%, by providing more technical information. However, the effect of training varied with different training method. For example, professional training was able to significantly increase the adoption by 10%. The training subjects with strong trust was able to effectively spread technical information, but the training effect was weakened when controlling the subject preference. Both of the training method, the guidance for theory and practice, and self-learning theory, was able to help farmers master technical information. Nevertheless, the training was still effective when taking preference into consideration. Conclusion: The soil testing and formula fertilization technology can reduce the application of chemical fertilizer, and training can relieve the problem of insufficient information during the adoption. To promote green production, we need to pay attention to technology promotion and information transmission.
