Pruning wound Pinaster oil and Resina Cupressi hot melt rear enclosed, it is to avoid insect pest and bleeding infringement, accelerate tree body spontaneous recovery；
In 2.4 months, rejuvenation shoot after grafting is pruned, after branch is turned green, carry out drawing branch to process, at rejuvenation grafting
Reason finishes.
Compared with prior art, the substantive distinguishing features of the present invention are：
1. using biological treatment, promote veteran kryptoblast to develop, method is not only safe and reliable, and innovation is developed
Position and control of highly getting back, are easy to the management such as kind grafting and later stage pruning, are that Semen Castaneae veteran rejuvenation, volume increase etc. improve handss
Section, there is provided technical foundation；
2. after adopting Pinaster oil and Resina Cupressi hot melt, the method for the coating larger wound of tree body, relative with lime water rubbing method
Ratio not only can reduce pest and disease damage pollution, the bleeding phase can also be avoided to damage, accelerate tree body spontaneous recovery；And convenient, side collected by material
Method is simple；
3. original major branch repeatedly being removed year by year, both having been decreased tree body injury it is ensured that often having harvest every year and permissible
Reduce and do not survive because once removing rear rejuvenation grafting, the tree body injury causing.
4. tree vigo(u)r recovers fast, prunes the 3rd year (grafting Second Year) and recovers tree vigo(u)r completely, yield obtains compared with rejuvenation before processing
It is doubled and redoubled.
