Early spring tomato seedling method and precautions

This year is almost over. Recently, many farmers have been making vegetable planting knowledge reserves for the beginning of the spring, and how to raise seedlings for early spring tomatoes? What are the precautions? In general, to achieve high returns, crops are strong. Let's take a look at the seedling technology points of early spring tomato together with the small series of Huinong.

First, seed disinfection

Disinfecting seeds is also used to control various pests and diseases of tomatoes. Generally, the method of soaking seeds with warm soup is used. The main method is to put the seeds into hot water of 55 degrees, soak them for about 15 minutes while stirring, and then put them in. Soak in 30 degrees of warm water for about four or five hours.

Second, the seedbed soil disinfection

After the bed soil is watered before sowing, spray the seedbed with 72.2% Plex water 500-600 times, spraying 2~4 kg per square meter. Or carbendazim disinfection, use 50% carbendazim WP 25-30g per 1000kg bed soil. When treating, firstly prepare carbendazim into an aqueous solution, then spray it on the bed soil, mix well and use plastic film. Closely covered, it usually kills many pathogens such as blight in the soil after 2 to 3 days.

Third, early application of base fertilizer

When the nutrient soil is prepared, the fertilizer applied is sufficient, and the whole seedling period can be used without fertilization. If the color of the seedling leaves is lightened and the symptoms of deficiency are found, a small amount of potassium dihydrogen phosphate 500 times solution can be sprayed.

Fourth, the temperature is properly regulated

After the seedlings, the temperature of the seedbed should not be too high, so that the seedlings grow robustly and enhance the cold resistance and disease resistance. During the "two leaves and one heart" period, the insulation measures of the seedbed should not be kept up. If the temperature continues to be low, the flower bud differentiation will be hindered. In early spring, the flowers will fall seriously, affecting the early yield. At noon on sunny days, the temperature of the seedbed is very easy to be high. Large ventilation, in order to prevent seedlings from being too large due to temperature difference, excessive water loss and wilting or death.

Fifth, do not make the seedbed humidity too large

There is generally no need to water the seedlings. When watering must be done, choose sunny noon and water for warm water. Never overdo it, in case the seedbed is too large, resulting in bad eyes, dead skin and disease. In order to prevent the humidity of the seedbed from being too large after application, the wood ash or fine dry soil can be used to absorb moisture.

6. Don't make the seedlings lack light.

When the seedlings are wintering, they often encounter yin weather. At this time, the outside temperature is very low. Many vegetable farmers do not dare to reveal the grass curtains, causing the seedlings to disappear for many days and affecting the formation and development of the seedlings and cauliflowers due to malnutrition. To increase the light, always keep the cover clean and the straw curtains should be removed as early as possible. On cloudy days, the grass curtain should be uncovered normally, and the time of illumination should be increased as much as possible.

Seven, do not ignore the prevention of pests and diseases

Tomato seedling stage is prone to rickets and blight, so we should remove the disease seedlings in the early stage of the disease, and then spray protection to prevent spread.

Eight, do not plant without seedlings

5 to 7 days before planting, the seedlings should have a refining process to enhance the seedling resistance and adapt to the post-planting environment. It is forbidden to directly plant the seedlings in order to prevent the environmental discomfort after planting, resulting in slow seedlings and serious dead seedlings after planting.

The above is the method of early spring tomato seedlings. The vegetable farmers who have not yet mastered can collect spares. I hope that everyone can master the knowledge as soon as possible and strive for a good income in the coming year.
