Management techniques after tomato planting

Tomatoes are tomatoes, which are very common vegetables in our daily life. They can also be used as raw fruits. Nowadays, there are a lot of people growing tomatoes, and the first thing to grow tomatoes is to raise seedlings. After raising seedlings, transplanting and planting were carried out according to the growth situation. The management after tomato planting is very important, which directly affects the yield of tomato. So the editor today brings you the management technology after tomato planting, let's have a look!

1. Temperature control

After tomato planting, the greenhouse should be properly sealed to increase the air temperature and soil temperature in the greenhouse and promote the slow seedling. After the slow seedling stage of tomato seedlings, the daytime temperature can be controlled at about 26-27 degrees, and the temperature difference between day and night is kept at about 10 degrees. When you pass the slow seedling period and the tomato enters the flowering and fruit stage, the temperature should be appropriately reduced to 23-24 degrees, and the temperature at night can be increased to about 17 degrees. Temperature is very important for the growth of tomatoes. We can regulate the temperature of the greenhouse by covering grass and reasonable ventilation.

2. Humidity control

The growth stage of tomato is different, and the requirement of humidity is also different. When planting slow seedlings, the requirement for humidity fluctuates greatly, generally about 35% and 90%. After entering the flowering and fruit stage, the humidity should not be too high, the soil water content should be kept at about 66%, and the air humidity should be kept at about 55%. When the tomato enters the fruit period, the humidity can be appropriately increased to about 75%, and the air humidity can be increased by 5%. If there is a shortage of water in the fruit period, then watering should be done well. Ventilation to reduce humidity, if the temperature is above 12 degrees, then you can pass through the wind all night.

3. Fertilizer and water management

In the early stage of tomato growth, make sure the soil is dry and wet, and keep the soil moist when the fruit is ripe and ready for harvest. When watering at the slow seedling stage, apply an appropriate amount of fertilizer according to the planting area. Urea is mainly used in the slow seedling stage, and appropriate amount of urea and potassium sulfate are applied when the first ear is about the size of a ping-pong ball. The third topdressing was carried out during the fruit expansion period of the second or third ear. Spray an appropriate amount of foliar fertilizer in the early stage of flowering, about once a month or so.

4. Pruning and branching

When the plant grows to about 25cm, it is necessary to do a good job of lifting the vine, support the support, and then tie the vine every 18cm or so with the passage of time. The pruning method of tomato is mainly double-trunk, and a lateral branch is retained in the first inflorescence of the main stem. In fact, it is mainly determined according to the variety of tomato, if it is an infinite growth variety, then it is mainly based on single stem pruning. All the pruning is carried out for the purpose of improving field permeability, promoting tomato growth and increasing yield.

The above is a brief introduction to the management technology of tomato after planting. The management of tomato after planting can not be ignored, we must pay more attention to it. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
