With the development of the vegetable industry in the facility, the tomato planting area continues to expand. In order to achieve high yields, Miao Miao Miao Zhuang is fundamental. The following points should be noted when raising the seedlings:
1. Seed disinfection: The prevention and treatment of tomato leaf blight, spot blight, early blight, ulcer diseases and other diseases should be selected soaking seedlings, that is, put the seeds in hot water at 55 °C, soaking with stirring for 15 minutes, after Soak it in warm water at 30°C for 4 to 5 hours, then remove and germinate at 30°C. For the prevention of viral diseases, 10% trisodium phosphate solution may be used to soak seeds for 20 minutes and then rinsed with clean water.
2. Disinfection of seedbed soil: After soaking the soil in bed before sowing, spray the seedbed with 72.2% Preclo 500 ~ 600 times liquid and spray 2 ~ 4 kg per square meter. For carbendazim disinfection, use 50% carbendazim WP for every 1000 kg of bed soil. When processing, mix carbendazim solution first, then spray on bed soil, and mix well with plastic film. Covered closely, usually by 2 to 3 days to kill the soil in the wilt and other pathogens.
3. Fertilizer applied in the preparation of nutritious soil is sufficient, the entire seedling stage can not be fertilized, if the color of the seedling leaves is lightened, when there are symptoms of lack of fertilizer, potassium dihydrogen phosphate 500 times that can be sprayed with a guaranteed quality can be applied.
4. The temperature is properly controlled. After Qimiao, the temperature management of the seedbed should not be too high, so that the seedlings grow robustly, and the cold resistance and disease resistance are enhanced. "Two-leaf and one-hearted" period should not avoid seedbed insulation measures can not keep up, if the temperature continues to be low, the flower bud differentiation will be obstructed, early spring flower drop, serious impact on early production, sunny noon, seedling temperature is easy to high, this time should not be exposed Large ventilation to prevent seedlings from wilting or dying due to excessive temperature changes and excessive water loss.
5. Do not make the seedbed humidity too high. Seedlings (especially wintering) generally do not require watering. When you have to water, choose sunny noon and water it with warm water. Avoid excessive watering to prevent the seedbed from becoming too large, resulting in rotten eyes, frozen seedlings, and diseases. After spraying, in order to prevent the humidity of seedbeds from being too large, weeds can be damped with grass ash or fine dry soil.
6. Do not see seedlings lack of light. The overwintering stage of the seedlings often encountered continuous yin weather. At this time, the outside temperature is very low. Many vegetable farmers dare not reveal the straw curtain, causing the seedlings to lose sight of the light for many days, and affect the formation and development of cauliflower seedlings due to malnutrition. To increase the light, keep the cover clean and try to remove the cover as early as possible. On cloudy days, we must also uncover the straw curtains and increase the lighting time as much as possible.
7. Do not ignore the prevention of pests and diseases. Seedlings are susceptible to blight and damping-off. At the early stage of disease, the diseased seedlings are firstly removed and then sprayed and protected in time to prevent the spread.
8. Do not colonize without hardening seedlings. 5 to 7 days before planting, seedlings should have a hardening process to enhance seedling resistance and to adapt to the environment after planting. Do not avoid direct planting seedlings in order to prevent environmental discomfort after planting, resulting in slow seedling slowing after planting, serious phenomenon of dead seedlings.
