疫病是甜椒保护地栽培中重要的真菌病害。该病一旦发生,发展很快,几天内可使成片或整个温室大棚植株枯死,损失惨重。笔者根据多年生产实践发现,利用科学的栽培技术可有效控制疫病发生,并且辣椒产量高、效益好。但在已发病的情况下,必须使用化学药剂进行防冶。一、为害症状甜椒的整个生育期均可发生疫病,尤以现蕾、坐果期最易感染和发病,茎、叶、花、果各部位都可染病。植株茎部受害,近地表茎基部和分枝交界处形成黑褐色病斑,并迅速扩展环绕茎1圈,病部表皮腐
Blight is an important fungal disease in the cultivation of sweet pepper. In the event of the disease, the rapid development of a few days can make into a film or the entire greenhouse plants withered, heavy losses. Based on years of production practice, the author found that the use of scientific cultivation techniques can effectively control the occurrence of the epidemic, and the pepper has high yield and good efficiency. However, in the case of illness, chemical agents must be used to prevent it. First, the symptoms of pests Bell pepper may occur throughout the growing period of disease, especially in budding, fruit setting most susceptible to infection and disease, stems, leaves, flowers, fruit and all parts can be infected. Plant stem damage, near the surface of the base of the stem and branches at the junction of the formation of dark brown spots, and rapidly spread around the stem 1 circle, disease epidermal rot
