参与式技术发展在毛竹笋用林施肥管理中的应用

The Application of Participatory Technology Development on Fertilizing Management of Shoot-utilizing Stand of Moso Bamboo

应用参与式技术发展方法,通过对毛竹笋用林培育技术问题的诊断,设计了以全面支持对毛竹笋用林开展肥培管理、改善施肥时间和发展测土施肥等3个技术层面的农民参与式技术发展方案,对笋用林施肥管理技术进行试验、提升和推广.研究表明,应用测土施肥技术可提高毛竹冬笋产量1.2～6.8倍,净产值提高1.4～3.9倍.通过技术发展过程中多个利益相关群体的参与及合作,提高了该技术的地方适应性、农民的试验能力和技术推广人员解决生产问题的能力.

The fertilizing management techniques of shoot-utilizing stand of Phyllostachys edulis (Carr.) H. De Lehaie were tested, improved and generalized by the method of participatory technology development. Participatory technology development plan, which includes encouraging fertilizing, adjusting fertilizing time and testing and utilizing of fertilizer recommendation based on soil testing, was designed by the analysis of cultivation technique of shoot-utilizing stand of P.edulis. The results showed that winter shoot output increased 1.2~6.8 folds and net production value increased 1.4~3.9 folds. Local adaptability of technology, innovation ability of peasants and the ability of technology generalization staff to solving problems were enhanced by the participation and cooperation of benefit-related groups during the process of technology development.
