Abstract:The effect of increasing yield for Pinus massoniana in seedling seed orchard was analyzed. Result shows that: compared to the afforestation seedling of general local stand, the mean height, diameter, and volume of the fiveyear-old stand increase by 13. 71%,19. 66% & 47. 68%, respectively, and l 1-year-old stand increase by 8.81%, 10. 19% & 24. 14%, respectively. Adopting improved technologies for constructing Pinus massoniana in seedling seed orchard is feasible,and the effect of yield increase is significant.
Keywords:Pinus massoniana  seedling seed orchard  growth of stand
