| 摘 要： | 通过对17a生马尾松近熟林施肥试验4年的生长效应分析表明:在南方红壤地区施适量的P,K肥对马尾松近熟林生长有显著的促进作用,但施用过量却有负作用;施N肥短期内对林木生长不利;施肥效果显著时可掩盖林地本身质量对林木生长的影响。根据对各肥种水平效应值的分析可知,最佳施肥处理为每株混施P2O590g,K2O 90g,其4年蓄积定期生长量比对照高13.4%。施肥措施对促进小径阶木生长有利。在肥效期内施肥措施与马尾松近熟林的生长效应呈显著相关性。

| Abstract: | 4 years’test data study on 17-year-old near-mature Masson Pine fertilization showed that applying N fertilizer was disadvantageous to the growth of plantation in short time in south red soil area,while fertilizing properly P and K improved the growth of near-mature plantation significantly and applying much was disadvantageous.It would cover up site affections on growth of tree when affecting is significant after fertilizing.Accord to the analysis of effects of different treatments,it showed that optimal application amounts of P,K were P2O5 90g,K2O 90g per tree,compared with the control,which increased the periodic increments of volume by 13.4% after 4 years.Fertilization could promote smaller diameter grade tree growing.Regression analysis showed that fertilization presented significant correlation to growth of near-mature forest. |
