Hydroponic Culture technique of Tomato

Hydroponic technology has also been cultivated in China for a long time. At present, hydroponic technology can mainly cultivate a variety of vegetables. The common ones are leafy vegetables. These dwarf vegetables are relatively easy to hydroponic. But vegetables like tomatoes are also geese that can be cultured in aqueous solution. They can even do simple hydroponic culture at home. Let's learn how to do it now.

1. Soaking seeds to accelerate germination

First soak the seeds in 5 degrees hot water to promote germination, stir constantly to avoid scalding, then soak the seeds in 25 degrees warm water, soak them until the seeds absorb water and expand, you can wrap them with a clean wet cloth and put them in a ventilated place to accelerate germination. Most of the light must be blocked. Then wait for it to sprout for about 2 to 3 days.

2. Configure the culture medium

Use clear water and prepared nutrient solution, generally by calcium nitrate 707g, add water 10 liters, stir well; then configure potassium nitrate 404.2 grams, potassium sulfate 260.7 grams, ammonium nitrate 40 grams, magnesium sulfate 152.1 grams stirring together, add water 10 liters. Then put clear water in the nutrition tank, then pour in the first solution, then add water to stir, up to 0.8t, you can pour into the second configuration solution, add water to stir, up to 1t can not add water.

3. Training equipment

Need to cultivate containers, nutrition tanks, but also need some facilities to add solution, in addition, the solution can be recycled, so there should be a special circulation equipment pipeline. The second is that a certain amount of oxygen is needed in the nutrient solution, and then there must be oxygen-increasing equipment. After the tomato grows, it needs some scaffolds to support the plant growth. It can be fixed with wire.

4. Seedling planting

First use a seedling tray to raise seedlings, generally put a seed in a hole, sow it into the medium, and then take out the seedlings to clean the roots of the seedlings after emergence, and put them into the holes in the cultivation bed, usually below is the nutrition trough. And then it's okay.

5. Management

Grow to a certain height, need pruning, generally leave double stem type, one branch leaves two growing points, retain robust lateral branches, step by step to stay branches can, you can adjust the number of retained branches. Sometimes extra-root topdressing is needed for nutrient supply. generally, topdressing once every half a month can also be decided according to tomato growth.

Hydroponic tomato is mainly cultivated by recycling nutrient solution, which can reduce diseases and improve the quality of tomato, but the cost of hydroponic greenhouse cultivation is relatively high, so it is suitable for green vegetable cultivation. Then it's easier to do simple hydroponics at home.
