第二代马尾松种子园应该采取怎样的密度设计是种子园建设的关键技术之一。本文通过对马尾松嫁接母树全光照、种子园林缘及种子园林分中马尾松生长发育差异的研究，提出新建马尾松种子园营建技术中株行距控制为8×8米，不要低于6×8米。并根据马尾松树种生物学特征及参考有关文献建议马尾松种子园良种生产时间（种子园生命期）定为20至25年。

Pinus massonia grafting seed trees growing in different conditions (full-light open gaps, marginal, intra-plantation) in a seed orchard were investigated and analyzed for their growth performances including tree height, DBH, Canopy diameter, under branch height, lowest seed-bearing height, seeding stratum thickness, etc. It is uggested that masson pine seed orchard be constructed with superior seeds (life cycle of the orchard) is 20-25 years. intensity of 8 x 8m, and the time period for producing
