对南疆骏枣黑斑病病原菌进行了分离、鉴定,并对其防治措施进行了研究。结果表明,骏枣黑斑病病原菌为链格孢菌(Alternaria alternata),光照不利于链格孢菌生长,其最适生长p H为6~8;RH为25%时,其菌落直径较小,为1.83cm,且生长缓慢;从鲜枣上分离、筛选的10个拮抗酵母菌中,J0对链格孢菌抑菌效果最佳,抑菌圈直径最大,为3.43 cm;7种中草药提取液对其链格孢菌的抑制作用,以黄连提取液抑菌效果最好。
The southern pathogen jujube black spot pathogens were isolated and identified, and its control measures were studied. The results showed that Alternaria alternata was the pathogen of Alternaria alternata and the light was not conducive to the growth of Alternaria alternata. The optimum growth pH was 6 ~ 8. When the RH was 25%, the diameter of the colony was small , Which was 1.83 cm and grew slowly. Among the 10 antagonistic yeasts isolated from fresh date, J0 had the best antibacterial effect against Alternaria, and the largest diameter of the inhibition zone was 3.43 cm. Seven Chinese herbal extracts Liquid on the inhibition of Alternaria, to extract the best antibacterial effect of Coptis.
