| 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. |
