施肥对不同林龄红松生长及结实的影响
|
摘要
对不同林龄红松施加速效肥,研究肥料对生长及结实的促进作用。结果表明,肥料对于红松生长促进作用不明显,但对胸径生长的影响要大于对树高生长的影响,在培养大径材过程中可以适当施肥;施肥对于提高结实量作用较明显,尤其对大龄树木单株提升较多,但从整体林分结实量的提升上,几种林龄相差不大。
The quick-acting fertilizer was applied to Pinus koraiensis at different stand ages to study the promoting effect of fertilizer on growth and fruiting. Result shows that the fertilizer has no significant effect on growth of Pinus koraiensis, but the effect on DBH growth is greater than that on tree height growth,appropriate fertilization can be applied during the process of large diameter timber.Fertilization is more effective in increasing the amount of fruit,especially for the individual older trees, but there is little difference in the number of forests from the improvement of the overall stand.
