Vegetable seed sowing method
Seed treatment before vegetable sowing can first cultivate strong seedlings, and second, it can prevent diseases. It is a very cost-effective measure to increase production. First, the selection of seeds for seed drying can increase the plumpness of seeds, increase grain weight, and increase seed viability. Sawn seeds can promote seed ripening and increase seed vigor and germination potential. Second, dry heat disinfection for tomato seed treatment. The first drying of the species, so that its moisture content reduced to 7% or less, placed in a 70-73 °C oven baking 4 days, then remove the soaking germination, can prevent a variety of diseases. Third, remove the mucus general seed surface has a layer of mucus wrapped, before sowing with 1% of baking soda aqueous solution soaking for 12-24 hours, repeated scrubbing several times, rinse clean to remove the mucus around the seed to promote rapid germination neat. Fourth, warm soup soaking this method is to break the seed dormancy, promote germination, sterilization, disease prevention, and enhance the effective measures of seed resistance. Water temperature and time should be accurate when soaking and cool immediately after immersion. Such as tomato soaking water temperature of 52 ° C, soaking time of half an hour; sweet pepper, cucumber, eggplant soaking temperature of 55 ° C, soaking time of 12 minutes; celery is 48 ° C, soaking for half an hour. How to prevent tomato early blight, eggplant brown leaf disease, sweet pepper anthrax, cucumber angular spot disease, celery spot blight and so on. 5. Liquor soaking seeds, white wine and water according to the weight ratio of 1:0.5:0.5, firstly mix the liquor with water, then put the seeds into the soak for 10 minutes, remove and wash with water. 6. Bleaching mud Mud the bleach into the mud. The amount of bleaching powder is calculated based on 10-20 active ingredients per kilogram of seed. The amount of mud is just enough to mix the seeds well. Mixing the bleaching mud and seeds and storing them in containers for 16 hours effectively kills black rot on cabbage, cabbage, broccoli, celery, and radish seeds. 7. Soaking seed with potassium permanganate solution First, soak the seed in hot water at 50°C for 25 minutes, dip it in a 1% potassium permanganate solution for 15 minutes, and finally rinse with clean water. 8. Soaking in Sodium Hydroxide Soak the vegetables for 4 hours with fresh water and place in 2% sodium hydroxide solution for 15 minutes. Rinse with fresh water and dry for 18 hours. This method can kill all kinds of viruses and fungi inside and outside vegetable seeds, prevent vegetable viruses, anthracnose, keratoses, and late-to-late diseases, and can decompose mucilage and oil outside the seed coat to avoid rotting. 9. Chloroform soaked in chloroform Also known as chloroform, it is an organic solvent with strong bactericidal capacity. It can kill viruses and fungi inside and outside the vegetable seed, dissolve pectin and mucus in the seed coat, and have the role of germination. Add 4 parts white spray and 1 part of chloroform, the amount to flood the seeds can be soaked for 10 minutes with detergent soak for 5 minutes, then rinse with water, dry for 6 hours to sow. Chloroform is toxic, and liquor added to chloroform cannot be used for drinking. Ten, soaking in copper sulfate solution Soak seeds in fresh water for 4-5 hours, then dip for 5 minutes in 105 cupric sulfate solution. 11. Seed soaking with thiophanate-methyl seed Firstly, soak seeds for 6 hours, soak for 1 hour with 0.1% thiophanate-methyl, then soak in fresh water for 3 hours, and dry for 18 hours to prevent fungal diseases. Twelve, seed dressing seed into a clean container, and then according to the seed weight of 0.3% -0.6% by adding Fumei Shuang, carbendazim and other agents, so that the agent evenly adhered to the seed surface, can kill more Eggs.
