摘要
应用参与式技术评估方法,对遂昌县三仁乡的3个村51户农户进行调查,采用因子分析法,研究了毛竹冬春笋产量下降的原因。结果表明:(1)冻雨雪灾害后,竹林结构的不合理,包括立竹密度下降和年龄结构不合理;(2)经营技术不合理,主要包括竹农对于留竹数量的不合理、竹材砍伐时间不合理、竹林施肥技术的不合理以及竹林土壤管理的不合理;(3)技术的缺失,经营者不满足于当前的技术,需要实地操作的现场指导和提供新技术培训。
Using the method of participation assessment, 51 households in three villages of Sanren Township, Suichang County were investigated to study the factors resulting in the yield decline of winter-spring bamboo shoots of Phyllostachys heterocycla cv. pubescenz. The results showed that the reasons may include the following aspects： （ 1 ） after freezing rain and snow disasters, the unreasonable structure, including decreased bamboo density and unbalanced age structure of the bamboo forest, was formed; （2） unreasonable managements, such as the standing number of bamboos, cutting time, fertilization techniques and soil management, were introduced ; （3） the lack of advanced technology was confronted, requiring on-site guidance to field operations and train in new technologies.
