摘要
对福建柏马尾松混交林的透光伐和整枝试验研究,结果表明,透光伐和整枝是混交林郁闭初期(5-7年)种间关系调整的主要技术措施,实施透光伐不但改善了混交林分的小气候环境和土壤性状,而且林分生产力得到明显地提高。透光伐后3年,混交林中的福建柏平均树高、胸径和材积依次比对照中的福建柏增加7.18%、15.89%和17.95%,同时伴生树种的生长量也得到明显提高;整枝后3年,主林木树高,胸径生长量依次比对照提高14.43%和16.33%。本研究表明在混交林7年生左右,对伴生树种进行透光伐,伐除强度约为15%,同时对主林木进行修枝能收到较好的效果,可进一步推广应用。
Study on release - thinning and pruning in stands of Fokienia hodginsii mix Pinuns Massortiana. The results showed that release - thinning and pruning are main technique measure of mixed forest interspecific relation adjustment in close canopy earlier （5 -7 years）. The release - thinning not only improving microclimate environment and soil character of mixed forest, but also increasing productivity markedly. After release - thinning 3 years, the average tree high, DB H and volume measure of Fokiertia hodginsii one by one in order compare check to increase 7.18% , 15. 89% and 17.95%, the growth of concomitant tree also get an obvious exaltation in the meantime. Pruning 3 years, the average tree high, DBH and volume measure of main wood tree one by one in order compare check to raise 14.43% and 16.33%.
This research is enunciation, at 7 years or so, carrying on release - thinning to the concomitant tree, it＇s intensity is about 15%, in the meantime carrying on pruning to the main wood tree can receive better result, can expand an application further
