【摘要】 为了提高低产毛竹林效益,对粤北毛竹林进行了施肥效果试验。结果表明:每年的9月份进行施肥较合适,施林用复合肥30 kg/667m2较适合,每年新竹在120～130株左右,毛竹眉径在8～8.5 cm之间,年新增价值在550～650元/667m2之间。2005～2008年的经济效益与施肥抚育前相比,效益增长倍数分别是6.5、7.5、15.9和22.5倍。更多还原

【Abstract】 In order to improve the economic benefit of low-production bamboo,the experiments of fertilization effects were developed on Phyllostachys edulis forests in northern Guangdong.The results showed that: The most appropriate time of fertilization was September for each year;the suitable fertilization volume was 30 kg/667 m2 compound fertilizer and the number of new bamboo was around 120～130;the eyebrow-diameter of Ph.edulis is 8～8.5 cm;the added value in unit area was at 550～650$.The multiples economic benefits growth compared with that before tending and fertilization from 2005 to 2008 were 6.5,7.5,15.9 and 22.5 times,respectively.更多还原
