【摘要】 在建立的13 53hm2毛竹笋材两用林试验、示范点,开发研究了笋材两用林丰产结构调控、加强林地管理以及科学配方施肥等配套技术,并对其技术效果和效益进行了评价。开发研究结果表明:溧阳龙潭林场屋后山和句容磨盘牧羊场试验林2001～2002年度比1997～1998年度竹材蓄积量度均增产12 77t/hm2,增长率为63 4%,较试验前对照林蓄积量增长率101 7%;示范林竹材产量较试验前对照林增长率为64 7%。试验林竹笋产量比试验前增产3 41t/hm2,增长率为442 9%,较对照林产量增长率为674 0%;示范林较对照林增长率为508 2%。纯收入比试验前增加1 0997万元/hm2,较对照林增加收入1 1206万元/hm2;示范林较对照林增加0 73万元/hm2。因此,实践证明,该技术先进、适用,效果明显,效益显著。更多还原

【Abstract】 In the 13.53 hm2 trial and demonstration plantations of Phyllostachys pubescens established for shoottimber products,the techniques of highyielding construction regulation,forest management and fertilizer application were studied and their effects were appraised.It was conduded that the timber volume of trial plantations in between 2001～2002 increased 12.77 t (or by 63.4%) per hm2 over that in between 1997～1998,and by 101.7% over that in CK before trial.The timber produce of demonstration plantations increased by 64.7% over that in CK before trial.And the shoot output of trial plantations increased 3.41 t (or by 442.9%) per hm2 over that before trial,and by 674.0% over that in CK.The shoot output of demonstration plantations increased by 508.2% over that in CK.Thereby the economic benefits from the abovementioned techniques were raised greatly indeed.更多还原
