蔬菜生产周期短,复种指数高,由于受地理条件、种植习惯和品种资源的限制,土壤病原物逐年积累,导致蔬菜病害重、产量低、品质差。控制土传病害已成为蔬菜植保工作的重要内容。现提出几种农防方法供参考。 Vegetable production cycle is short, high multiple crop index, due to geographical conditions, planting habits and varieties of resources, soil pathogens accumulated year after year, leading to heavy vegetable diseases, low yield and poor quality. Control of soil-borne diseases has become an important part of vegetable plant protection. Several kinds of agricultural methods are now proposed for reference.
