摘　　要：为探讨撑绿竹纸浆林最佳的施肥配比,通过田间肥料试验,研究3种不同施肥配比处理对撑绿竹新竹的生长、产量和经济效益的影响。结果表明:单施蚯蚓粪有机肥处理的撑绿竹新竹的立竹数、胸径和产量较对照依次增加50.19%、6.75%和61.25%,但差异不显著,产投比为1.06;单施无机肥处理的撑绿竹新竹的立竹数、胸径和产量较对照依次增加116.73%、21.79%和172.83%,产投比为1.21;蚯蚓粪有机肥+无机肥处理的撑绿竹新竹的立竹数、胸径和产量较对照依次增加183.66%、24.40%和272.11%,产投比为1.89,差异显著。蚯蚓粪有机肥与无机肥配合施用增产和增收效果最好。The effects of three different fertilization treatments on growth, yield and economic benefit of Bambusa pervariabilis × Dendrocalamopsis daii were studied by field experiment to explore the best fertilizer ratio. Compared with CK, the culm number per clump, DBH and yield of bamboo applied with vermicompost organic fertilizer were increased by 50. 19%, 6. 75% and 61. 25% respectively without significant difference, and the output-input ratio of the treatment was 1.06. The culm number per clump, DBH and yield of bamboo applied with inorganic fertilizers were increased by 116. 73%~, 21. 79% and 172.83% respectively with significant difference, and the output-input ratio of the treatment was 1.21, and that of bamboo applied with vermicompost organic fertilizer and inorganic fertilizers were increased by 183.66%, 24. 40% and 272. ll% respectively with significant difference, and the output-input ratio reached 1. 89. All above indicated that application of organic and inorganic fertilizers was the best to increase the yield and income of the bamboo.
