不同营养元素的施肥处理对马尾松近熟林木材基本性质的影响

研究了 4种不同营养元素的施肥处理对马尾松近熟林木材基本性质的影响。结果表明 ,在不同施肥处理后的同一年中 ,N、P、K、NPK施肥处理对木材管胞长、宽及基本密度的影响不同 ,同一施肥处理在不同年度中 ,对上述性质的影响亦异 ,总之 ,无明显变化规律。方差分析表明 4个施肥处理与无施肥处理的管胞长、宽及基本密度差异均不显著 ,生长轮宽度与管胞形态和基本密度都不显著相关。

Influence of Fertilization with Different Nutrient Elements on the Wood Basic Properties of Pinus massoniana in Near-Mature Forest

Research was conducted on the influence of fertilization with four kinds of nutrient elements on the wood basic properties of Pinus massoniana in near mature forest. The results indicated that there were different effects on wood tracheid length, tracheid width and basic density after different fertilizer treatments in same year or in different years after same fertilizer treatment. In a word, the rule of variety wasn't marked. Results of variance analysis showed that wood tracheid length, tracheid width and basic density in all the treatments were not significantly different to the control treatment (CK). Meanwhile there were not significant correlations between the width of growth ring and tracheid shape, the width of growth ring and basic density. The experiment indicates the fertilizer treatments to near mature forest of Pinus massoniana could not only promote the tree growth but also keep the basic wood properties, even there were some slight improvements in it. This study can provide some references for the application of fertilizer treatment to Pinus massoniana in near mature forest.
