立木杨树防腐药液的上升与气象因子的相关性

文献综述

摘要:我国是一个木材资源极度稀缺的国家，如何高效、合理利用木材资源，延长木材使用寿命，已成为亟需解决的问题。作为三大重要速生树种之一的杨木，其杨木立木注药防腐处理工艺将日趋于重要。由于木材水分输导模式影响防腐药液上升高度从而造成防腐效果差。通过测定药液上升的影响因素快速确定最合适的注药时机。本文概括了国内外有关树干径流与气象因子的相关性和立木注药的研究成果。

Correlation between the rise of Poplar preservative liquid and Meteorological factors

overview

Abstract: China is a country where timber resources are extremely scarce. How to utilize wood resources efficiently and reasonably and prolong wood service life has become an urgent problem. As one of the three important fast-growing tree species, poplar has become an urgent problem. The anticorrosion treatment technology of poplar stumwood injection will be more and more important. Due to the influence of wood moisture transport mode on the rising height of preservative liquid, the anticorrosion effect is poor. The most suitable factors are determined quickly by determining the influencing factors of the rising of poplar liquid. This paper summarizes the research results of correlation between trunk runoff and meteorological factors and injected into the trunk at home and abroad.

前言:杨树分布广，生长快，在江苏得到了广泛的种植，并已成为徐州、淮安、宿迁等城市的支柱产业。^[1]但由于速生杨木生产周期短，密度低，材质松软，易变色、易腐朽等缺点限制了速生杨木的高效利用。^[2]为了实现劣材优用，须对杨木进行防腐处理。研究药液上升与气象因子的相关性，从杨树基部注入防腐药液，药液随着树干径流流动，向上运输到树梢，达到立木杨树防腐处理的目的。分析太阳辐射、温湿度气象因子与杨树防腐药液上升的相关性对确定立木杨树防腐药液注入时间、监控防腐药液上升高度、防腐效益有着重要的作用。
