Chinese people can't leave tomatoes on the table, but it is inevitable that there will be pesticide residues in the market. Then why not do your own tomato planting. Tomatoes are hi-light plants, while potted plants need to pay attention to the characteristics of grafting and extension, and the living climate and planting conditions of tomato pot plants are introduced in detail. Let's take a look at how to plant tomatoes.
The first step: seed treatment
Remove the harvested tomato seeds and soak them in water for about 2 hours. Then remove them and immerse them in warm water at a temperature of about 55 degrees Celsius. The soaking time is 15 minutes. It is easy to cause the seeds to be cooked. After 15 minutes, the water temperature is lowered and kept at a constant temperature. The tomato seeds are placed in it. When it is about 4 hours, it will germinate. At this time, hot water can be added, and the circulation can be carried out on the tomato seeds. The role of disinfection and prevention of pathology.
Step 2: Sowing
Tomato seeds are slightly smaller, and sowing can be determined according to the size of the soil. Generally, the planting density is about 10 grams per square meter. If the relevant conditions are met, the seedbed can be constructed before planting, which can increase the germination rate.
The sowing site should have relevant drainage performance, mainly using sunlight for its photosynthetic needs, or directly selecting artificial heating equipment to achieve the seedling effect.
The sowing time is spring, the month is 2-3 months, and the next autumn season can also be planted. Usually, the sowing method is selected, without deliberate soil covering, and the shading effect can be achieved through straw and shade net.
The third step: field management
Temperature requirements: Tomato is a thermophilic plant, and the living environment of tomato cultivation has a temperature range of 25-28 degrees Celsius. Secondly, the temperature difference between summer and winter should be strictly distinguished. In summer, the daytime temperature should be controlled to about 28 degrees Celsius, and the nighttime temperature is 16-18 degrees Celsius. In winter, the overall temperature is controlled to be around 15 degrees Celsius.
Humidity requirements: When planting tomatoes, a large amount of water supply is required, and the overall humidity requirement is high. It is necessary to properly control the moisture, and the humidity is controlled to be about 35%.
Fertilization principle: When planting tomatoes, all stages need to be supplemented with sufficient nutrients. During the growth period, they pay more attention to nitrogen, potassium and phosphate fertilizers. In the later stage of growth, organic fertilizers can be selected.
The fourth step: pest control
Tomato cultivation, the main diseases of pests and diseases are tomato flower skin, tomato fruit hollow, tomato bacterial spot disease, umbilical fruit, sunburn fruit, green fruit, brown fruit and so on.
The main cause of tomato pests and diseases is that the daily maintenance is not suitable, or the cultivation methods, or the management details, etc., are usually reflected in the results period. Therefore, it is necessary to pay attention to management, mainly based on scientific cultivation methods, formula fertilization, and It is able to detect diseases in time and make prevention.
