In the process of raising seedlings, eggplant melons and fruiting plants often suffer from damping-off caused by damping-off diseases and blight. In severe cases, the death of seedlings and seedlings will cause some loss in production, in order to effectively reduce and control the period of vegetable growing. Seed-borne bacteria, soil-borne diseases, and various diseases caused by plant protection personnel at all levels must seriously disinfect seed and soil to prevent the occurrence of disease at seedling stage. I. Seed Disinfection and Disease Prevention 2.5% Shile Suspending Seed Coating Agent Disinfection is the latest popularization and application of seed treatment technology. It can kill the pathogenic fungi hidden in the seed coat and can infiltrate into the seeds to kill the invading seeds. Fungi, and after the seeds are sown, can form a bacteriostatic protection ring around the seeds, so that the seedlings can be successfully unearthed without being attacked by pathogenic fungi. The emergence rate is high, the emergence is early, the seedlings are thick, and the root and stem diseases of vegetables are effectively prevented. Method: Use 2.5% of Coke 1000 times treatment, first the 4th of a thousandth of the pure dry seed weight, and then dilute it with a small amount of water 1:10, then pour the seeds to be treated and stir until they are fully colored. Mix and use. It can effectively control diseases such as damping-off and damping-off in seedling melons. Second, seedbed soil disinfection treatment choose to avoid the wind to the high flat land for the seedbed, and deep trenches, in order to facilitate drainage and lower groundwater level, such as the old seedbed, you must change to new soil to reduce the bacteria source, base fertilizer to use full maturity Organic fertilizer has good disease prevention effect. Simultaneous disinfection of bed soil. Specific methods, use "Zhuangbobo granule fertilizer" bed soil disinfection, usage: first cultivating bed soil, 1 square meter with "Zhuangbobo" fertilizer 100 grams. Sprinkle evenly in the bed field and pour enough water to cover it with a plastic film and seal it for 7 days. It must be pressed around. After 7 days, the film was peeled off and the seeds were waited for 5-7 days before seeding, which effectively controlled the pathogenic bacteria of damping-off and blight and invaded the roots of the eggplant, melon and melon seedlings to reduce the incidence.
