毛竹林带状采伐后垦复施肥对新竹生长及土壤养分含量的影响

为了解毛竹林带状采伐后采取垦复施肥经营方式对竹林快速更新恢复的效果,筛选毂优组合模式,为毛竹林梁伐更新恢复过程中嘉效培育提供理论依据。本研究以福建省潦平市毛竹林地为研究对象,设置8米来伐宽度,采用竹苑施肥(A)、髫复方式(B）和施肥比例(C)3因素3水平L(3')正交试验设计,探讨带状采伐下毛竹林蟹复施肥对出笋数、立竹数以及土壤氮,磷、钾养分含量的影响,分析新竹生长及土壤养分的相关关系。结果表明;3个因素对毛竹出笋数和立竹数重要性顺序相同。

To clarify the effects of reclamation and fertilization management on the rapid regeneration and recovery of moso bamboo forests following strip cutting, and screen the optimal combination pattern, this study aims to provide a theoretical basis for high-efficiency cultivation during the regeneration and recovery process of moso bamboo forests after harvesting. Taking the moso bamboo forest land in Zhangping City, Fujian Province as the research subject, this study set a cutting width of 8 meters, and conducted a 3-factor, 3-level L(3^3) orthogonal experimental design with three factors: stump fertilization (A), reclamation method (B), and fertilization ratio (C). The study investigated the impacts of reclamation and fertilization on the number of emerging bamboo shoots, the number of standing bamboo plants, and the contents of soil nitrogen, phosphorus and potassium nutrients in moso bamboo stands under strip cutting, and analyzed the correlation between new bamboo growth and soil nutrient contents. The results showed that the order of importance of the three factors for the number of emerging bamboo shoots and the number of standing bamboo plants was identical.
