Greenhouse soilless tomato planting technology management

Tomatoes , also known as tomatoes, are a common fruit and vegetable. Greenhouse tomatoes are grown using soilless cultivation technology, which not only has high yields but also tastes good. Below we will introduce to you the technical management of soilless tomato cultivation in greenhouse.

1. Seedling cultivation

Choose tomato varieties with large, full seeds, vigorous growth, strong disease resistance, and good quality. Soak the seeds in warm water for several hours, rub the attachments on the surface of the seeds with your hands, take out the seeds and disinfect them. After wrapping the seeds in wet cloth and disinfecting them, place them in a constant temperature box for germination.

2. Cultivation medium

The substrate can be vermiculite, sawdust, rock wool or a mixed substrate. If substrate bag culture is used, a substrate with a lighter texture should be selected. Pure perlite can be used, or perlite mixed with 1/3 to 1/2 peat. If a mixed matrix is ​​used, the raw materials should be piled into a thickness of 25 cm 15 days before mixing and then sprayed with a wet film to disinfect and treat bacteria.

3. Irrigation equipment

Using tap water equipment or well water, you can also build a water storage tank with a water level difference of 1.5m to collect rainwater from the greenhouse or shed roof as a water source. Individual glass greenhouses can be equipped with independent irrigation equipment. Plastic pipes can be used for the main pipes in the shed and the drip irrigation tapes inside the cultivation troughs. It is only necessary to lay 1 to 2 pipes and install a 0.1mm thick plastic film to effectively prevent the drip irrigation water from leaking.

4. Planting and cultivation

The cultivation trough is fully irrigated with water, and after the water has fully penetrated into the soil, planting can be carried out. Water promptly after planting.

5. Fertilization and irrigation management

In the first 3 to 5 days after planting, irrigation should be done on a sunny day; after fruit setting, irrigation should be done once in the morning and once in the afternoon every day, with the irrigation time controlled within 15 to 20 minutes. Fertilization should be carried out 20 days after planting, and once every 7 days after fruit setting, with 25g of fertilizer applied each time. During this process, avoid applying fertilizer to the roots of the plants. Be sure to mix it into the substrate to ensure healthy growth of the plants.

6. Hanging vines and pruning

When the plant grows to 6 to 7 leaves, you can use plastic ropes to hang the vines to effectively ensure the vertical growth of the plant; for pruning, you should use single-trunk pruning and remove all side branches in the leaf axils.

7. Protect flowers and fruits

Use 10% to 15% 2,4-D solution to dip the flowers between 7:00 and 9:00 every day to effectively increase the fruit setting rate, retain 3 to 4 fruits, and promptly remove deformed fruits, diseased fruits, and rotten fruits to ensure the quality of tomato fruits.
