摘要: 针对安徽滁州地区林地土壤贫瘠,麻栎(Quercus acutissima)经营粗放的现状,开展了不同施肥(复合肥,氮:磷:钾=15%:15%:15%)处理(0、0.15、0.3、0.45 kg/株)对麻栎生长、生物量和热值影响的研究。结果表明:随施肥量增加,麻栎树高、胸径、地径和生物量均逐渐增大;以0.45 kg/株处理效果最好,树高、胸径、地径、树干生物量分别比对照增加15.47%、17.91%、14.48%、11.53%。施肥处理树干的干重热值均显著低于对照,比对照减少1.11%~2.53%;枝、叶、皮干重热值在不同处理之间没有显著差异。麻栎单株地上部分能量也随施肥量增加而增大。在安徽滁州地区单施复合肥可以显著提高麻栎生物量,尽管施肥降低了树干的热值,但由于生物量的大幅增加,使得林地能量产出随施肥量的增大显著增加。

Abstract: The nutrient content in forest soil is poor and the operation for oak plantation is extensive in Chuzhou, Anhui Province. The effect of fertilization (compound fertilizer, N:P:K= 15%:15%:15%) on growth, biomass and caloric values of sawtooth oak was evaluated in this study. The experiment included four fertilizer treatments: 0, 0.15, 0.3, 0.45 kg/tree. The results showed that the tree height (H), diameter at breast height (DBH), ground diameter (GD) and biomass of sawtooth oak increased with the amount of fertilizer. All the maximal values of these variables were obtained in the 0.45 kg/tree treatment, the H, DBH, GD and stem biomass increased by 15.47%, 17.91%, 14.48% and 11.53%, respectively, compared with the control treatment. The dry weight calorific values of stem were significantly lower in fertilization treatments than that in the control treatment, reduced by 1.11% to 2.53% compared with the control treatment. The dry weight calorific values of branches, leaves and bark had no significant difference among different treatments. The energy of aboveground sawtooth oak was also enhanced with the amount of fertilizer. Therefore, using compound fertilizer can significantly improve biomass of sawtooth oak and effectively increase the energy output of woodland in Chuzhou, although fertilization reduces the thermal value of the trunk.
