【摘要】 为探讨垦复对糙花少穗竹林出笋和生长规律的影响,分别选择垦复6、2a的样地各一处及一处未垦复样地进行出笋、高生长、幼竹生物量累积的调查与分析。结果表明:与未垦复竹林相比,垦复竹林不同程度地延长了出笋期。垦复6a的竹林笋质量和产量明显高于其他样地,退笋率低于其他样地,垦复促进了竹林产量的提高。垦复对糙花少穗竹幼竹高生长影响明显,尤其对高生长速生期的影响较大,明显促进了幼竹高生长过程中生物量的累积。更多还原

【Abstract】 Plots of Oligostachyum scabriflorum forest reclaimed for 6 years and 2 years respectively and a plot unreclaimed were selected to survey the rules of bamboo shooting, bamboo growth and biomass increasing for the purpose to research the effects of reclamation on bamboo shooting and growth. The results indicated that there were longer bamboo shooting stages in reclaimed plots compared with those in unreclaimed plot. The quality and productivity of bamboo shoots in plot reclaimed for 6 years were higher than those in other plots, and the percentage of bamboo shoots failing to growth in the plot reclaimed for 6 years was the minimum, meaning that the reclamation promoted the bamboo productivity. Reclamation for longer time made obvious influence on the height growth of young bamboo, especially at height fast-growing stage. Reclaiming for longer time promoted markedly the biomass accumulation in height growth of young bamboo. These results may provide some management basis to reclaim and utilize the wild bamboo forest.更多还原
