摘 要:通过在福鼎后坪国有林场开展檫树幼林期施肥对比试验,结果表明,经过施肥,檫树树高、地径和冠幅的平均值为2.302m、4.2cm和1.735m,而对照(没有施肥)树高、地径和冠幅的平均值为1.65m、2.76cm和1.19m,树高、地径和冠幅的生长分别比对照增加了39.5%、52.2%和46.8%。树高、地径和冠幅生长在不同年度间和不同处理间的差异均达极显著水平,地径和冠幅生长在不同重复间的差异达极显著水平,而树高在重复间的差异没有达到显著水平。树高、地径和冠幅生长在年度、处理和重复间的互作效应均达到极显著水平。可在不同年度、不同立地条件下采用不同的施肥量,以有效促进树高生长,减少幼林期的抚育管理成本。Fertilization comparative tests of the early Sassafras forest were carried out in Houping state-owned for- est in Fuding. The results were as follows: the average of tree height,ground diameter and crown were 2.302na, 4.2cm and 1.735m respectively through fertilization,and the control were only 1.65m,2.76cm and 1.19m respec- tively,height,ground diameter and crown growth were increased by 39.5%,52.2% and 46.8% respectively. Differ- ences of tree height, ground diameter and crown were very significant among different years and different treat- ment, differences of ground diameter and crown growth were very significant among repetitions, and the difference of tree height was not significant among repetitions. The interaction effects between tree height, ground diameter and crown were very significant. Different fertilization can be used in different years, different site conditions to promote tree height growth and to reduce the cost of cultivation and management of young forest.
