Status and Trend of Wood Preservation in Foreign Countries and Wood Preservation Measures in China

Wood preservation can prolong the service life of wood, guarantee a sparing use of timber and obtain significant economic and social benefits.(1) All countries in the world make a high estimate of wood preservation.(2) Kinds of preservatives tend to become diversified along with the expansion of the scope of their application.(3) The development trend is placing emphasis on high effect, low residue, no residue and no pollution.(4) Advantage of modern science and technology is taken of to uninterruptedly improve the preserving technique and to help it attain the objective of automation.Wood preservation in China started in 1950s.Much progress has been made in the past forty years, but the quantity of wood preserved is only 1% of the yield. Not only the quantity of wood preserved is very small, but the kind of preservatives used is also less in number. For these reasons, the author gives points in recommendation for the future development of wood preservation in China.(1) Give a full play to the potentiality of the existing production equipments(large, medium and small types) (2) Strengthen the organization and leadership. It is better for the wood preservation to be under the unified supervision and control of the State Planning Commission.(3) Leaders at all levels should pay more attention to the importance of wood preservation. Regulations and technical specifications concerning wood preservation should be laid down by government, and be put into effect under the supervision of government. Wood preservation should be centrally managed by the departments of wood preservation and wood supply, who supply the users with well preserved wood.(4) Government should adopt a preferential and economically incentive policy for wood preservation. For example, wood preservation charges arc allowed to be added to the production cost.(5) Set up "a Society of Wood Preservation Workers" to boost the development of wood preservation.(6) Strengthen the researches on the technique of wood preservation.
