采脂资源变化与技术革新

The Changing Trend of Masson pine Resin Resources and Technological Innovation of Bleeding

本文论述了我国马尾松松脂资源变化的趋势，指出我国南方主产脂区马尾松成、过熟林已所剩无几，本世纪末中龄马尾松人工林将成为采脂的主力军，但采脂技术水平低下，管理落后.针对上述问题提出了适合于中龄林采脂的新技术及集约化中龄林采脂基地管理新体系.

This paper discussed the changing trend of masson pine resin resources in China, pointed out that the middleaged masson pine plantations would be the main bleeding resources in the end of this century as a result of mature and over - mature natural masson pine forests resources being exhausted rapidly in southern China as well as backward bleeding technique and backward management. In view of existing situation, the paper put forward a new bleeding technique suitable for middle-aged masson pine plantations, and new intensive management system for middle -aged masson pine resin base.
