摘要
以福建省南平市延平区大横镇溪源村毛竹低产林分为试材，进行竹蔸配方施肥试验，以不施肥为对照。经连续4a的观测结果表明：竹蔸施1＃竹篼宝＋尿素的新竹产量最高，4 a达44213.85 kg · hm^-2，比对照增长57.56％；新竹株数比对照增长23.45％。其次是施2＃竹篼宝＋1％EM溶液，4 a新竹产量37670.25 kg· hm^-2，均超过丰产林标准。竹蔸配方施肥均可加快竹蔸腐烂速度，采用施有机肥＋EM生物肥效果最好，4 a内竹蔸完全腐烂数达89％，比对照提高83％，施用1＃竹篼宝＋尿素次之，4 a内竹蔸完全腐烂数达81％，比对照提高75％。竹蔸配方施肥经济效益较高，投入产出比在1∶10.5-1∶11.9之间，以施用1＃竹篼宝＋尿素的投入产出比最高。
The test of prescription fertilization in the felled bamboo base remains of Phyllostachy heterocycla cv.Pubescens was per-formed in the low yield forests of P.heterocycla cv.pubescens in Yuanxi village ,Daheng Town,Yanping District,Nanping City,Fujian province,and no fertilization was taken as the control.The results of 4-year continuous onservation showed：by treated with Zhudoubao （in Chinese） No.1 and urea fertilizer,the yield of new-born bamboo during the 4 years reached the highest with 44213.85 kg· hm^-2 which is 57.56%more than that of the contrast;the number of new-born bamboo was 23.45%more than that of the contrast.The sec-ond,by treated with Zhudoubao No.2 and 1%EM solution,the yield of new-born bamboo during the 4 years reached the highest with 37670.25 kg· hm^-2.Both of them exceeded the standard of high-yield plantation.The prescription fertilization in the felled bamboo base remains could accelerate the remains decay.The optimal method is to use the organic fertilizer and EM bio-fertilizer,the number of entirely rotted remains duing the 4 years reached 89%which was 83%more than that of the contrast.The second ,by using Zhudoubao No.1 and urea fertilizer ,the number of entirely rotted remains during the 4 years reached 81%which was 75%more than that of the contrast.The economic benefit was the highest of all by prescription fertilization in the felled bamboo base remains ,the input-output ra-tio was 1∶10.5-1∶11.9,and the optimal method was Zhudoubao （in Chinese） No.1 and urea fertilizer.
