| 摘 要： | 以撑绿竹为研究对象,通过肥料配比、施肥量和施肥方式3个因素不同水平的正交试验,对撑绿竹的施肥技术进行了研究。结果表明,促进撑绿竹胸径增粗的最佳施肥模式为:肥料配比(N:P2O5:K2O)为3:2:1,施肥量为1.2 kg/丛,施肥方式为撒施;提高撑绿竹繁殖率的最佳模式是:肥料配比(N:P2O5:K2O)为5:2:1,施肥量为0.6 kg/丛,施肥方式为穴施;增加撑绿竹生物量的最佳施肥模式为:肥料配比(N:P2O5:K2O)为5:2:1,施肥量为0.6 kg/丛,施肥方式为撒施。

| Abstract: | Fertilizer technology for Bambus pervariabilis×Dendrocalamopsis daii was carried out using orthogonal experimental design with fertilizer ration, application amount and application mode at different levels. The results showed that the best fertilization mode for larger bamboo DBH was 1.2 kg per clump with the ratio (N:P:K) of 3:2:1 by broadcasting application (covered soil and litter), and for the higher biomass was 0.6 kg per clump with (N:P:K) of 5:2:1 by broadcasting application. |
