Growth conditions,symptoms of ancient trees in the Master-of-Nets Garden were investigated,it was found that there were 6 ancient trees about 120-920 years old in this garden,belonging to 5 genera and 5 *** speaking,ancient trees in this garden grow well due to the proper protection,and 3 of them need only regular management,specifically,Pinus bungeana Zucc.,Podocarpus macrophyllus(Thunb.)***,Wisteria sinensis Sweet in south yard of Dianchun Yi(the Peony Study),while another three need key protection,specifically,Chaenomeles sinensis Koehne,Sabina chinensis(Linn.)Ant.,*** Sweet,2 of which need corrosion prevention and filling protection,and another one needs comprehensive techniques for the rejuvenation of tree *** view of symptoms of these 3 trees requiring key protection,corresponding techniques were proposed as below:3 steps for protecting *** Koehne(*** and sterilizing tree holes,painting anti-corrosion protective agent;*** holes;*** holes);3 steps for protecting *** Sweet(*** up rotten xylem;***-corrosion and sterilization processing for trunk;*** anti-corrosion agent);4 steps for ***(Linn.)Ant.(*** climbing plants around it;*** rotten xylem;*** holes;*** rhizosphere and rejuvenation of the tree).

The paper had studied growth situation and disease symptoms of ancient trees in Surging Waves *** were 14 ancient trees belonging to 10 genera of 9 families,with tree age of 120-260 *** trees had been well protected *** were 9 ancient trees growing well,occupying 64.29%,which were Ginkgo biloba,Cupressus funebris Endl.,Podocarpus macrophyllus,Zelkova schneideriana Hand.-Mazz,Cinnamomum camphora(L.)Presl,Buxus sinica,and Wisteria sinensis(Sims)*** were 5 ancient trees needing to be protected preferentially,occupying 35.71%,including Ligustrum lucidum,Osmanthus fragrans and Pterocarya *** disease symptoms were trunk rot and hollow *** on these symptoms,the paper had proposed protective measures for Ligustrum lucidum and Osmanthus fragrans:① enclosing eroding holes on the trunk;② clearing up eroded woodiness on the surface of trunk,disinfecting and applying anti-corrosion protectants;③ filling eroded holes of the *** measures for Pterocarya stenoptera included:① clearing up the inner part and interior walls;② disinfecting the inside and interior walls of holes;③ applying anti-corrosion protectants.
