(1) Preparation of seedbed soil Preparation of seedbed soil should be based on local conditions. Peat is one of the best materials for the preparation of tomato seedling bed soil. It has high light porosity, high organic matter content and abundant resources, and has great application potential. In addition, rice hull, slag, earth fertilizer, horse dung, etc. can all be used as seed bed soil. Forest rot is also known as shanpi soil. It is a mixture of decayed dead branches, weeds and weeds and surface soil accumulated in forests for many years. It has rich organic matter content, and can be directly mixed with garden soil to prepare bed soil after sieving. It needs a fermentation process and it is a good quick-release bed soil.
(2) Disinfection of bed soil before bed soil disinfection and sowing plays an important role in preventing and controlling plant diseases and insect pests at the seedling stage. Its purpose is prevention and prevention and merger. Combined with the actual production in China, bed soil disinfection is the most direct and most commonly used method of disinfection. The commonly used agents include 0.5% formalin, 65% zein zinc powder, 50% carbendazim powder, chloropicrin, and methyl bromide.
1 Formalin disinfection can prevent damping-off and sclerotium disease. Bed soil is sprayed with 0.5% formalin, mixed evenly, then stacked and sealed with plastic film for 5-7 days. The film is opened to completely evaporate the smell of the drug. Can be used afterwards.
2 zeinzin or zein powder disinfection with 65% of zeson zinc powder, 80 grams per cubic meter bed soil, or 50% carbendazim powder, 40 grams per cubic meter medication, fully mixed with the seedbed soil After being covered with a plastic film for 2-3 days, the film is removed, and the drug taste is completely volatilized before use, which has certain disease-preventing effects.
3 physical disinfection methods such as steam and microwave disinfection. In Europe, America, and Japan, commonly used steam sterilization bed soil is used to prevent damping-off, blight, blight, sclerotinia, and cucumber mosaic disease, and has good control effect. For example, the Netherlands uses steam to raise the soil temperature to 90-100°C and treat bed soil for half an hour. Steam-disinfected bed soil can be used after the soil temperature drops down. It is quickly disinfected and has no residue. It is a good method of disinfection. Microwave disinfection uses microwaves to irradiate the soil and kill grasses, nematodes and germs. For example, a microwave sterilizer consisting of a high-power 30-kilowatt microwave launcher and microwave launcher developed by the United States has a forward speed of 9.2-0.4 km/h. This is a walking microwave sterilizer with high working efficiency.
