Soilless cultured vegetables are required to prevent root rot

Although soilless cultivation vegetables have high yield and high quality, they are not affected by the season and occupy less land, they can effectively utilize water, fertilizer, and easy control of pests and diseases. However, due to the use of nutrient solution or nutrient soil, root rot occurs more commonly. The prevention and treatment of root rot should be noted: It is advisable to improve the facility cultivation bed to be closed and higher than the ground, and the liquid storage area should be covered to prevent the invasion of pathogens in the environment. The drainage groove of the matrix wall should be properly deepened, and the drainage should be kept unblocked to prevent bacteria from flowing back to the cultivation bed with the waste liquid, resulting in repeated infection. Seed Disinfection Seeds used for soilless cultivation must have the advantages of high germination rate, rapid growth, and neat emergence. Seed disinfection before sowing, can be soaked in warm soup or dry heat sterilization and other methods can also be used 0.2% neutral calcium hypochlorite soaking for 1 hour. Soilless cultivation is best to use seedlings grown without soil. Disinfect the nutrient solution Eridoid is applied once a month to the nutrient solution at a dosage of 20 mg per litre of nutrient solution, or 1 gram of zinc mandelone is added to 1000 liters of nutrient solution.
