毛竹周年采伐及经营管理配套技术研究

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 OF PHYLLOSTACHYS PUBESCENS

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.
