摘要
该文通过对葡萄白腐病病菌在生物学特性、发生规律和综合防治等方面进行试验和调查,得出葡萄欧美型品种较抗病,欧亚型品种较感病,葡萄糖、蔗糖最适于病菌生长发育。通过种植抗病品种、地面覆膜等措施,可以防止病菌侵染,在开花后到封穗期再辅以药剂防治基本可控制此病。
The biological characteristics,occurrence law and integrated control of grape white rot are tested and investigated,the results show that the European-American grape varieties are more resistant to the disease,while the European-Asian grape varieties are more susceptible to the disease.The range of optimal temperature for the growth of this pathogen is 20~30 ℃.Glucose and sucrose are most suitable for the growth and development of the pathogen.White rot of grape starts to occur in early June,and occurs seri...
