应用综合评分法 ,并引用经济权重对马尾松种于园无性系进行评价 ,具有合理、简便、实用等特点 ,符合经营目的。疏伐后 ,种子园优良无性系类型比率由 45 %提高至 6 3%。经预测无性系产籽量、出籽率、发芽率将分别提高 2 1 2 8%、7 99%、3 5 7%。家系树高、当年抽高将分别提高 2 10 %、2 16 %。

It is rational,handy and practical and tallies with the management aim to apply the comprehensive marking and introduce the economic weight for evaluating the clones in the seed orchard of Pinus massoniana.After the thinning,the rate of excellent clonal type in the seed orchard increases to 63% from 45%.According to the Prediction,the clonal seed producing amount,seed-producing percentage and germination percentage will increase by 21.28%,7.99% and 3.57% respectively and the family height and current year's height growth will increase by 2.10% and 2.16%,respectively.
