The incidence of PNRSV infection is the highest, CLSV infection is common, PDV infection is low, different virus mixed infection occurred, 65.8% of the trees were found to be infected with one or more viruses when the samples were detected by ELISA, PLMVd and PEV being found in the field are 1.0% and 0.2%.更多还原
