橡胶原木蓝变及防治方法初步研究

新鲜橡胶原木最易感染蓝变菌而引起木材蓝变。试验结果表明，造材后即用２％ＴＭＯ防霉剂喷涂端面，若在雨季喷药后再涂刷防水ＴＭＯ，一个月内效果良好，适用于鲜橡胶原木的短期保存。

Preliminary Study on Blue stain of Rubberwood Logs

Newly felled logs of rubberwood ( Hevea brasiliensis )are easy to be infected by blue stain fungus( botryodiplodia theobrmae ).Experiment results showed that it was an effective way to prevent the logs from bule stain to spray 2% TMO immediately,an anti mold chemical,on cut end surface after felling,and then brush water repellent 3% TMO coating on the surface,if in rainy season.The anti blue stain effect could sustain for one month.
