木材化学保管方法的研究

对新伐巴尾松剥皮或不剥皮原木喷以多种化学药剂进行了防腐、防虫试验研究、证明杀虫效果较好的有辛硫磷、倍硫磷和林丹，防腐效果较好的有6781、6782、6783、6784、FCAP、AC3B等；其中6781、6782能使剥皮尾松原木露天存放二年材质完好如新。枫香和拟赤扬剥皮原木喷药后棚内干存效果较好，但露天存放效果较差。锯材（厚板）瞬浸处理后棚内干存一年不霉不腐。

Studies on the chemical method for the protection of wood in storage

The experiments both indoors and outdoors, on the freshly felled logs of the Chinese red pine (Pinus massoniana) with or without bark which are sprayed with chemicals to protect against decay and insect damage show that the better insecticides are Phoxin, Fenthion and Lindane; and the better wood preservatives are 6781, 6782, 6783, 6784, FCAP, AC_3B etc. All of these preservatives are the water-borne. Being sprayed with 6781, 6782, the debarked pine logs are not degraded after storage outdoors for two years, and the quality of the wood keeps the same as the original.By dry storage indoors, it has the better result for the logs of hardwood (Liquidambar formosana and Alniphyllum fortunei) which are debarked and sprayed with chemicals, and it has the worse result to be stored outdoors.After dipping treatment on the fresh sawn-timber of hardwood (L. f. and A. f.) with 6782 preservative, it gives the better result in preventing mold and decay by dry storage indoors for one year.Rot occurs in all the control wood which degrades seriously and becomes substandard or useless after two years.
