With the development of the vegetable industry in the facility, the tomato planting area has been continuously expanded. In order to produce high yields, Miao Miao Miao Zhuang is fundamental. In early spring, nursery should pay attention to the following points:
1. Seed disinfection. To control diseases such as tomato leaf blight, spot blight, early blight, ulcer disease, etc., soak the seeds in warm water at 55°C, soak for 15 minutes while stirring, and then warm water at 30°C. Let it soak for 4 to 5 hours and germinate at 30°C. For the prevention and treatment of viral diseases, 10% trisodium phosphate solution may be used to soak seeds for 20 minutes and then rinsed with clean water. Eight Road Venture Network
2. Seedbed soil disinfection. After the bed is soaked with water, the seedbed is sprayed with 72.2% Precizer 500 to 600 times, spraying 2 to 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. Eight Road Venture Network
3. Early basal fertilizer. Fertilizer applied in the preparation of nutritious soil is sufficient, the entire seedling period can not be fertilized, if the color of the seedling leaves is lightened, there is a lack of fertilizer symptoms, you can spray a little quality assurance of potassium dihydrogen phosphate 500 times.
4. The temperature is properly controlled. After the seedlings are raised, the temperature of the seedbed should not be too high, so that the seedlings can grow robustly and enhance the cold resistance and disease resistance. "Two-leaf and one-hearted" period should not avoid seedbed insulation measures can not keep up, if the temperature is kept low, the flower bud differentiation will be hindered, early spring drop and fruit drop serious, affecting the early yield, 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.
Usually no watering at the seedling stage. When watering is necessary, choose sunny noon and use warm water for watering. 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.
Sweeteners refer to Food Additives that can impart sweetness to soft drinks. Sweeteners can be divided into nutritive sweeteners and non-nutritive sweeteners according to their nutritional value; according to their sweetness, they can be divided into low-sweetness sweeteners and high-sweetness sweeteners; according to their source Divided into natural sweeteners and synthetic sweeteners.
