对辽东山区部分红松人工林分杈树的结实和生长情况进行了调查 ,分析了林木早期分杈与生长、结实的关系。结果表明 ,早期分杈林木的单株材积比林分的平均单株材积大 2 7.1% ,分杈树的平均单株结实量是林分的平均单株结实量的 3.76倍。林木早期分杈有利于增加结实量 A survey was conducted on the fruiting and growth of some branches of Pinus koraiensis plantations in mountainous areas of eastern Liaoning Province. The relationship between the early twigs and growth and fruiting was analyzed. The results showed that the single plant volume of early bifurcated forest was 21.1% higher than that of stand, and the average bifurcation of bifurcated tree was 3.76 times of the average single plant stand of forest. Early bifurcation of trees helps to increase the yield
