摘要
为粤北地区低产、低效毛竹人工林合理的施肥量和最佳施肥期的确定提供参考,根据2004~2008年在广东省乐昌市五山镇的施肥试验和连续4 a的调查,对9个标准地的新竹数量和新竹眉径的平均数据进行对比和方差分析。结果表明:9月份施肥较合适,每666.7m2施复合肥30 kg较适合,每年新竹在120~130株左右,毛竹眉径在8~8.5 cm之间,每666.7m2年新增价值在550~650元之间,施肥增产效果明显。
To determine the most rational fertilizing amotmt and the optimal fertilizer application stage for deteriorated forest of Moso Bamboo (Phyllostachys pubescens) in North-Guangdong province, comparative analysis was performed on number and diameter of new bamboos in nine standard sites based on four consecutive years of fertilizer application and field survey. Results indicated that the reasonable stage and the amount of fertilizer application were in September and 30 kg compound fertilizer per 666.7 m^2, respectively. 120 to 130 new bamboos were produced yearly with the diameter ranging from to 8 to 8.5 cm, and newly-increased value per 666.7 m^2 was 550 to 650 Yuan, presenting a significant effect on increasing yield of Moso Bamboo.
