摘要
以河南省国有黄柏山林场多功能森林经营样板基地内14年生黄山松人工林为研究对象,采用随机区组方法,设置4种间伐强度,利用伐后5 a间连续测定数据,研究不同间伐强度对黄山松人工林生长的影响。结果表明:T_(45)、T_(34)、T_(23)对黄山松胸径、单株材积的生长均具有显著促进作用,并且随间伐强度的增加,促进作用越显著。随着间伐强度的增加,黄山松树高、单位面积蓄积年均增长率呈增大趋势,但相互间无显著差异,间伐对二者的生长无显著促进作用。黄山松人工林生物量年均增长率由大到小依次为T_(45)、T_(34)、CK、T_(23),且相互间无显著差异,间伐对生物量增长无显著促进作用。
Taking the 14-year-old Pinus taiwanensis plantation in the multi-purpose forest management model base of the state-owned Huangbaishan Forest Farm in Henan Province as the research object.Using randomized block method,4 kinds of thinning intensity were set,and the continuous measurement data of 5 years after cutting was used to study the effects of different thinning intensity on the growth of P.taiwanensis plantation.Results show that T45,T34 and T23 have significant effects on the growth of DBH and volume of P.taiwanensis,and the more obvious the effect is with the increase of thinning intensity.With the increase of thinning intensity,the height and stand volume growth rate of P.taiwanensis shows an increasing trend,but there is no significant among them.Thinning has no significant effect on the growth of both height and stand volume.The descending orde of biomass growth rate of P.taiwanensis plantation are T45,T34,CK and T23,and the mutual difference insignificant,thinning has no significant effect on biomass growth.
