How to grow tomatoes in the greenhouse? Planting techniques of Tomato in greenhouse

Tomato is the tomato that we often eat in our life, and the market demand in our country is very great. Tomato can not only be eaten raw, but also can be used to stir-fry and extract fresh with other dishes, its nutritional value is relatively large. At present, there are many planting patterns of tomato, and greenhouse planting is one of the common ones. So how to grow tomatoes in the greenhouse? The following editor brings you the planting technology of tomato in the greenhouse, let's have a look!

1. Greenhouse construction

When planting greenhouse tomatoes, the first step is to do a good job in building the greenhouse. When building a tomato greenhouse, the first thing we have to consider is the water source and the place. Around the greenhouse to ensure that there are adequate and clean water, to ensure that tomatoes in the growth can have sufficient irrigation water, to meet the water needs of tomato growth. Then in the establishment of the greenhouse, the terrain should choose a flat ground, according to the actual situation to control the length and width. In general, the width of the greenhouse should be maintained at about 5 meters. In order to manage and ventilate the greenhouse, doors should be left at both ends of the greenhouse.

2. Seed treatment

Before sowing, we should first do a good job of drying seeds, generally drying for about two days, drying seeds is mainly to kill the germs in the outer layer of the seeds, so as to improve the germination rate of seeds. Then soak the seeds in potassium permanganate, carbendazim and other solutions for about half an hour. After soaking the seeds, put the seeds at a temperature of about 28 degrees to promote germination. Then select seedling tray, nutrition and nutrition pool and other seedling equipment. Disinfect with the equipment, and the soil should be disinfected in place to ensure that tomato seeds can germinate normally. Then it is necessary to apply sufficient base fertilizer, mainly farm fertilizer, combined with appropriate amount of compound fertilizer, and then sow seeds at the right time.

3. Seedling management

To do a good job of management after sowing, first of all, we should pay attention to the management of temperature. The temperature of the greenhouse should be kept at about 30 degrees in the daytime and 15 degrees at night, which is the optimum temperature for the growth of tomato seedlings. Then the greenhouse should maintain a certain amount of air flow and air humidity, and the air humidity should not be too high, just keep it at about 40%. It is necessary to start fertilization when the seedlings grow to 4 leaves, but because the seedlings are relatively fragile at this time, we should pay attention to controlling the amount of fertilizer applied, and we can start transplanting when about 8 leaves are grown.

4. Daily management

After planting, the growth rate of tomato will be accelerated, at this time the requirement of temperature and humidity of tomato is relatively high. Therefore, we must pay attention to control the temperature and humidity, especially the temperature, not too low, to prevent the seedlings from freezing damage. Seedlings in the early stage of growth, the demand for water is not very large, so watering should not be too much. Otherwise, it will have a great impact on the growth of the plant, and in the middle and later growth, the demand for water of tomato will increase. Water properly every day, reduce the amount of water properly in the rainy season, and do a good job of drainage. In addition, we also need to do a good job in pest control, plant pruning and fruit management.

The above is a brief introduction of tomato planting technology in greenhouse. That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
