Abstract:The following contents are involved in the paper; 1.The best secondary host of Schlechtendalia chinensis in Guizhou is Plagiomnium maximoviczii (Lindb.) T. Kop.2.The secondary hosts can be propagated by cutting into small fragments about 0.8 cm in length and then in broadcast sowing. The propagation area can be 8 times higher than its breeding material area.3. There are different propagation methods in different climate and soil conditions.4. After inoculating Schlechtendalia chinensis on Plagiomnium maximovi-czii which propagated in the experimental forest of Rhus chinensis, its Kop-pei or horned gall production is 13 times of the natural production.
