长期连作重茬、管水不科学、感病品种的大面积栽培、田间不卫生、现代农产品物流等因素的综合作用,导致冬春季蔬菜菌核病发生流行。采取水旱轮作、选用抗病品种、建立无病苗圃、推广高畦或设施栽培、降低田间湿度、配方施肥、清洁田园、科学施药等综合措施,较为有效地控制了冬春季蔬菜菌核病的发生为害。
Long-term continuous cropping, water unscientific, large-scale cultivation of susceptible varieties, unhygienic fields, modern agricultural products logistics and other factors, led to the prevalence of sclerotinia in winter and spring. Comprehensive measures such as water and drought rotation, selection of disease-resistant breeds, establishment of disease-free nurseries, promotion of highland or cultivation of cultivated plants, reduction of field humidity, formula fertilization, clean-up of farmland and scientific application of pesticides are more effective in controlling sclerotinia in winter and spring Harmful.
