What vegetables can be grown without soil?

Vegetable soilless culture is the most advanced cultivation technology in the world today, because soilless culture has many advantages over soilless culture, so in recent years the development of soilless culture area showed a straight upward trend, the general types of soilless culture mainly have hydroponic culture, rock wool culture and substrate culture three categories, let's take a look at which vegetables can be soilless culture bar!

What vegetables can be grown without soil?

1. Soilless hydroponic culture: lettuce, rape, celery, beet, cabbage, leek, garlic seedling, amaranth, etc.

2. Rock wool cultivation: tomatoes, cucumbers, bitter gourd, zucchini, sweet peppers, etc.

3. Substrate cultivation: potato, radish, colored pepper, pepper, tomato, eggplant, etc.

What are the types of soilless culture?

1, soilless culture: hydroponic vegetables refer to most of the roots grow in the nutrient solution layer, only through the nutrient solution to provide water, nutrients, oxygen is different from the traditional soil cultivation form of vegetables, but seedlings may use certain substrates.

Rock wool cultivation: rock wool cultivation is to plant in pre-made rock wool, rock wool by 60% diabase, 20% limestone and 20% coke at 1600℃ high temperature melt spray into 0.005 mm fiber and pressed into blocks.

3. Substrate cultivation: Substrate cultivation is to fix the roots of crops in organic or inorganic substrates, and supply nutrient solution to crops by drip irrigation or trickle irrigation. The cultivation substrates can be placed in plastic bags and spread in cultivation ditches or grooves.

Advantages of soilless vegetable cultivation

1, can improve the yield: soilless cultivation of crops required for various nutrients are artificially prepared into nutrient solution application, according to the crop type and the different growth stages of the same crop, scientific supply of nutrients, so the crop growth and development robust, strong growth potential.

2, environmental hygiene: soilless cultivation is applied inorganic fertilizer, and soil cultivation organic fertilizer, fertilizer decomposition fermentation, odor pollution environment, but also make a lot of pest eggs breeding, harm crops, so soilless cultivation does not exist these problems.

3. Water saving, fertilizer saving and labor saving: soilless cultivation does not require cultivation, ploughing, weeding and other operations, saving labor and labor. Watering and topdressing are solved simultaneously, and the liquid supply system regularly and quantitatively supplies, so that waste is not caused, and the management is very convenient, and the labor intensity is greatly reduced.

4, avoid continuous cropping obstacles: soilless culture can avoid continuous cropping obstacles, in vegetable cultivation, reasonable rotation of land, avoid continuous cropping is one of the important measures to prevent serious disease occurrence and spread, and soilless culture is fundamentally solved this problem.

5, not limited by the soil: soilless cultivation makes crops completely out of the soil environment, not limited by soil, water conditions, many deserts on the earth, wasteland or difficult to cultivate areas, can be used by soilless cultivation methods.

6, make full use of space: soilless culture get rid of the constraints of the land, so can not be limited by space, can use the flat roof of the city building to plant vegetables and flowers, virtually expand the cultivation area, but also according to people's will for production.
