彭场林场高产脂、高产材湿地松优树选择研究

Study on Selection of Superior Tree Producing High-rosin and High - wood from Pinus Elliottii at Pengchang Forest Farm

摘要:

以荆门市彭场林场66．7hm^2 30多年生湿地松母树林为研究对象，经过连续几年的观测和调查，采用普选法，以材积和产脂量双指标控制，选择出了14株高产脂、高产材优树，其材积比一般湿地松大20％，产脂量高200％，为湿地松优良品系改良与推广打下了基础。

Abstract:

After continuous years observing and surveying on the over-30-years-old Pinus elliottii mother forest as object of study was 66.7 hm^2 at Pengchang Forest Farm. The volume and rosin quantity were studied, controllably by means of common selection method. 14 superior trees that produce high-rosin and high - wood had been selected form Pinus elliottii mother trees, the results showed that volume and lipid quantity were 20% and 200% of ordinary Pinus elliottii respectively, this all offered a good foundation for reforming and generalizing of Pinus elliottii superior breeds.
