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.
