Bag Removing Date and the Technology of Promoting Scion Shooting for Camellia Changing Crown

In order to apply height grafting technology to production better,moisture bag removing date after graft union healing and the technology of promoting scion shooting were studied. After grafting for 150 days,results showed that the death rate of grated buds was the lowest after grafting for 75 days to remove moisture bag,with 26. 67%. The differences in the death rate of grated buds,the ratio of shooting and the length of shooting were not obvious after grafting 75 days to 120 days to remove moisture bag. Using 6-ba for spraying treatment could significantly improve the scion shooting,among which the effect was the most obvious when using 1 500 mg / L 6-ba to spray with the ratio of shooting increasing from 60. 83% to 77. 78%,and the length and coarseness of shooting improved significantly.
