摘 要:为满足现代竹材加工业生产周年供竹的需要,开展毛竹周年采伐及经营管理配套技术的研究。结果表明,在毛竹1个生理周期中,除每年3~5月和白露前后半个月外,其余16个月可伐第4度毛竹,这对竹笋和竹材产量的影响不明显,可提高未来第2度竹竹笋的产量,实施周年采伐后,对竹材的抗拉、抗压强度最大下降7%,对竹制品的性能无明显影响;施尿素可提高经济产量,以每公顷施300kg以上为好。实行周年采伐还必需加强林政管理,以杜绝乱砍乱伐现象发生。Study on cutting throughout the year and management technique demonstrated that in one physiological circle of Phyllostachys pubescens,except every March,April and May,15 days before and after White Dew,8-year bamboo could be cut in the other 16 months.It had no evident effect on shoot and timber yield,meanwhile,could increase shoot yield of the next 2-year bamboo.It had no evident effect on properties of bamboo work,the maximum decrease oftensile strength and compressive strength was 7%.Application of urea could increase economic yield, over 300 kg/hm2.Meantime,forestry administration should be enhanced.
