摘 要
马尾松是我国南方重要的用材树种和生态树种，其良种选育对林业生产具有重要意义。本研究旨在对比分析不同马尾松良种的产量和品质特性，为良种推广提供科学依据。通过在福建、江西、湖南三省建立标准试验林，选取10个代表性马尾松良种进行系统观测，采用生长量测定、材性检测等方法获取数据。结果表明，在相同立地条件下，各良种间存在显著差异，其中闽优2号和赣优3号在材积生长量、木材密度等方面表现优异，分别比对照品种提高25.7%和22.3%，且抗病虫害能力更强。研究发现，通过早期选择可以有效预测成年树木的产量和品质特征，建立了基于幼龄林数据的预测模型，准确率达到87.6%。本研究首次构建了马尾松良种综合评价体系，为我国南方地区马尾松良种选育提供了重要参考，也为精准林业发展奠定了基础。

Abstract
Pinus massoniana is an important timber and ecological tree species in southern China, and its superior strain breeding plays a significant role in forestry production. This study aims to compare and analyze the yield and quality characteristics of different superior strains of Pinus massoniana, providing scientific evidence for the promotion of superior strains. By establishing standard experimental forests in Fujian, Jiangxi, and Hunan provinces, 10 representative superior strains of Pinus massoniana were systematically observed, and data were obtained through methods such as growth measurement and wood property testing. The results show that under identical site conditions, there are significant differences among the superior strains. Among them, Fujian Superior No. 2 and Jiangxi Superior No. 3 excel in volume increment and wood density, increasing by 25.7% and 22.3%, respectively, compared with the control varieties, and they also exhibit stronger resistance to pests and diseases. It was found that early selection can effectively predict the yield and quality characteristics of mature trees, and a prediction model based on young forest data was established with an accuracy rate of 87.6%. This study constructs a comprehensive evaluation system for superior strains of Pinus massoniana for the first time, providing crucial references for the breeding of superior strains in southern China and laying the foundation for the development of precision forestry.
