麻栎修枝与施肥对比试验及效益分析

Contrast Tests and Benefit Analysis on Pruning and Fertilization of Quercus acutissima Plantations

本文以滁州市红琊山林场麻栎人工林为研究对象,进行3年的修枝施肥交互试验,以及不同肥料种类和不同施肥量对比试验,初步掌握了修枝与施肥,以及施用不同肥料和同一肥料不同施肥量对林分生长量和生物量的影响。结果表明,修枝可有效地促进林分生长,尤其是对造林密度大的林分;施肥虽可促进林木生长,但在施肥时也增加了成本,综合效果不明显。

In this paper Quercus acutissima plantations on Hongyashan Forest Farm of Chuzhou City were selected as the study objects. 3-year-long pruning and fertilization cross tests and contrast tests with different types of fertilizers and different fertilizing amounts were carried out. The effects of pruning and fertilization, fertilizer types and fertilizing amounts on the increments and biomasses of the plantation stands were basically understood. The results showed that pruning could promote growth of the stands effectively, especially of the high-density stands. Although fertilization could promote growth of the stands, it increased the cost and the combined effects were not significant.
