By the trials of the added sprouts on Slash Pine× Caribbean Pine F2 hybirds seed seedlings, the effect indicated the most elite shear method in the cutting orchard is to cut the tip and keep the 10cm height of seed production stand, to shear fragile side-twigs, cut the tip of the thick branches to reach the same level height between main stem and branches, and to control the 3~4 class ramifications to form a flat roof seedling which the main stem is short and the branches is long. The survival percentage of seed production stand are to reach 96.7% and average quantities of added sprouts on one tree are 95.8.
