| 摘 要： | 马尾松幼林整地和施肥试验表明:在三明Ⅱ类地立地条件下,施肥与不施肥的4年生林分在生长量上没有显著差异;不同整地方式幼林树高和胸径的生长均有显著差异,在中上坡块状整地的林分比不整地的林分树高大26%,胸径大15%,蓄积量大15%,在中下坡树高、胸径、蓄积量分别大14%、24%和45%,但全面整地和块状整地间的林分生长差异不显著;中下坡和有整地的林分生物量明显大于中上坡和不整地的林分。树干生物量符合方程:W(干)=0.062(D2H)1.049;块状整地的投资效益最好,中上坡的投资效益依次为:块状整地>全面整地>不整地,中下坡依次为块状整地>不整地>全面整地。

| Abstract: | The result showed on the second grade of site condition,there wasn't evident difference between biomass of 4-year-old stand with application and without application;there were evident differences between tree heights of young forests with different site preparation and between dbh of those;the patch site preparation input benefit was best,the input benefits on mid and up slopes were: patch site preparation>overall site preparation> none of site preparation,those on mid and low slopes were: patch site preparation> none of site preparation>overall site preparation. |
