Which vegetables can be cultivated with soilless soil? Are tomatoes, balsam pear and lettuce suitable?

Soilless cultivation is a kind of planting method popularized in recent years, which is rich in types and is widely used in vegetable cultivation. A big difference with the previous soil planting method is that the whole process does not use soil, but what is indispensable is the allocation of nutrient solution, which is also a key factor for crop growth. So, in our life, which vegetables can be cultivated with soilless? Are tomatoes, balsam pear and lettuce all suitable?

What are the types of soilless cultivation?

There are many types of soilless cultivation, such as water culture, substrate cultivation, rock wool cultivation, aerosol culture and so on. Our common is hydroponic vegetables, that is, put the root system in the configured nutrient solution, the whole process does not need soil, rely entirely on the nutrient solution to provide nutrients and water. In recent years, hydroponic vegetables have also been vigorously promoted, compared with the traditional soil culture is healthier, fertilizer use efficiency is high, and will not produce toxins.

Substrate cultivation is to put the root system in the inorganic or organic substrate and slowly irrigate the nutrient solution.

The way of fog culture is also very simple, mainly through high pressure to make the water spray directly on the root.

The cultivation of rock wool is relatively more demanding, and the rock wool that can be transplanted plants must be made in advance before the follow-up maintenance work can be carried out.

Which vegetables can be cultivated without soil?

There are many vegetables suitable for soilless cultivation, and different types of soilless cultivation are suitable for different vegetables. Tomato, balsam pear and lettuce are all suitable, but the types are different:

For example, there are tomatoes, eggplant, sharp peppers, potatoes and so on.

Rock wool cultivated balsam pear, cucumber, sweet pepper, zucchini and so on.

In hydroponics, there are lettuce, celery, hollow cabbage, rape, leek and so on.

Why is soilless cultivation becoming more and more popular? Take hydroponic lettuce for example, hydroponic culture compared with soil cultivation of fewer diseases and insect pests, natural varieties of better shape, higher commercial value. For example, the quality and yield of cucumber cultivated by rock wool is better than that of soil cultivation, and it is easier to take care of in the planting process, with fewer diseases and insect pests and no need to hit a lot of pesticides, so it can be called a real green food.

Third, is the cost of soilless cultivation vegetable input high?

Many people think that the input cost of soilless cultivation is high, but it is not. With the progress of science and technology, soilless cultivation has become a long-term beneficial planting method with one-time investment. The specific input cost depends on the variety cultivated, the type of soilless cultivation selected, the cultivation area and the material of the greenhouse.

According to the type of soilless cultivation, the basic input cost of hydroponic culture, substrate cultivation and rock wool cultivation is less than 10,000 mu. The most expensive is the floating board capillary hydroponics, and the investment of one mu of land is about 150000.

According to the material of the greenhouse, the standard solar greenhouse is about 50, 000 yuan per mu, which is more expensive, while the cheaper ones are bamboo greenhouse and steel pipe greenhouse, and the price per mu fluctuates between 5000 and 8000.

Conclusion: soilless cultivation has many advantages compared with traditional cultivation methods. Whether growers choose this method or not depends on their own needs. After all, the investment is relatively high.
