The latest tutorial on soilless cultivation techniques of Tomato

Tomato is one of our common fruits and vegetables, it tastes sweet and sour, quality and cheap, very popular, and its planting area is increasing year by year. However, the traditional soil culture method has a low yield and is vulnerable to the threat of diseases and insect pests. nowadays, with the popularization of soilless cultivation technology, tomatoes can also be cultivated without soil, and the tomatoes planted have high yield and good quality. below, the pro-agricultural network will explain the soilless cultivation techniques of tomatoes.

1. Facility conditions

Soilless cultivation is different from the traditional planting methods, it needs the help of facilities to grow, including cultivation trough, irrigation facilities and so on. Among them, the cultivation trough is the key point of soilless cultivation, and it is the growing place of tomatoes. Generally, every 3-5 cultivation grooves need to be equipped with a storage tank to replenish the water content of the cultivation tank at any time. The height of the storage tank is higher than that of the cultivation tank, and the water level is controlled. Convenient watering.

2. Allocation of cultivation substrate

The key point of soilless cultivation technology lies in the cultivation substrate, which determines the key point of high yield and high yield of tomatoes. In order to provide the nutrient balance needed for tomato growth, the cultivation substrate is mainly organic matter. For example, after the corn straw in the crops is chopped and the organic fertilizer is mature, it can be successfully mixed with the slag and added some special fertilizer for soilless cultivation of tomatoes. Generally, corn straw and organic fertilizer each account for about 40%, while the slag is about 20%. After deployment, it can be filled into the cultivation tank after high-temperature disinfection and sterilization.

3. Sowing and raising seedlings

Before sowing, the seeds are treated to improve the germination rate. Soak the seeds in baking soda with very low concentration for half an hour, which can eliminate the bacteria on the surface of the seeds and reduce the occurrence of diseases and insect pests. After soaking, remove and clean the seeds, then put them in a plastic bag or wet towel and place them in a greenhouse environment of 25-28. The seeds can be sown when the seed epidermis begins to whiten. Sowing should be uniform, should not be too dense, after sowing the preservation temperature between 25-30 degrees, about a few days later can sprout.

4. Colonization

After emergence, 3-4 true leaves can be planted, fill up the substrate in the cultivation trough before planting, and then irrigate until the substrate absorbs enough water. After these are done, they can be planted in holes like traditional planting. Generally, two rows are made in each slot, and the row spacing is about 25-35cm. If the seedlings are planted vertically and in the hole, the cultivation of soil is higher than that of Miao Tuo.

5. Cultivation and management

To maintain sufficient light and suitable temperature after planting, the suitable temperature for tomatoes is 10-28 degrees, 20-25 degrees during the day and 10-15 degrees at night. Fertilizer should be applied 20 days after planting, less than 15 grams of special fertilizer per plant, once after the fruit, sprinkle the fertilizer on the root system, and then water to make it infiltrate naturally, and pay attention to the management of hanging vine and pruning during growth.

The above is the soilless cultivation technology of tomato brought by the pro-agricultural network for you. Although the soilless cultivation technology has high yield and quality, it needs to pay attention to a lot of problems, which is more complex than planting with soil.
