一、掌握温度与棚菜病害的关系病原菌侵染植物,引发病害,与栽培环境的温度关系十分密切。当温度进入到某个温度区域时,会发生与该温度相对应的病害。使经销商可以事先预测将要发生的病害,从而做出物资储备和诊断准备。根据多年经验积累,归纳出蔬菜主要病害发生所需要的温度条件。(各地的防治药剂可经营者自主确定)。1、低温阶段(18℃以下)⑴主导病害:细菌性病害—角斑病、圆斑病。
First, grasp the relationship between temperature and greenhouse disease Pathogen infection of plants, causing disease, and the cultivation of the environment temperature is very close. When the temperature enters a certain temperature range, a disease corresponding to the temperature occurs. So that dealers can predict in advance the disease will occur, so as to make the material reserve and diagnostic preparation. According to years of accumulated experience, summed up the main vegetable diseases occur in the required temperature conditions. (Control agents throughout the operator can be determined independently). 1, low temperature stage (below 18 ℃) ⑴ dominant disease: bacterial diseases - angular leaf spot, circular spot disease.
