Which vegetables can be cultivated without soil?

Soilless cultivation of vegetables is the most advanced cultivation technology in the world today. Because soilless cultivation has many advantages over soilless cultivation, the area of soilless cultivation has increased linearly in recent years. Generally, there are three types of soilless cultivation: hydroponic culture, rock wool culture and substrate culture. Let's take a look at which vegetables can be cultivated without soil.

Which vegetables can be cultivated without soil?

1. Soilless hydroponics: lettuce, rape, celery, beet, hollow cabbage, leek, garlic, amaranth and so on.

2. Rock wool cultivation: tomato, cucumber, balsam pear, zucchini, sweet pepper and so on.

3. Substrate cultivation: potato, radish, colored pepper, sharp pepper, tomato, eggplant and so on.

What are the types of soilless cultivation?

1. Soilless hydroponic culture: hydroponic vegetables refer to vegetables that grow in nutrient liquid layers and provide water, nutrients and oxygen only through nutrient solution, which is different from traditional soil cultivation, but some substrates may be used in seedling cultivation.

2. Rock wool cultivation: rock wool cultivation is to plant plants in prefabricated rock wool. Rock wool is made of 60% diabase, 20% limestone and 20% coke melted and sprayed into 0.005 mm fibers and pressed into blocks at 1600 ℃.

3. Substrate cultivation: substrate cultivation is to fix crop roots in organic or inorganic substrates and supply crop nutrient solution through drip irrigation or trickle irrigation. The cultivation substrate can be packed in plastic bags and laid in cultivation ditches or grooves.

Advantages of soilless cultivation of vegetables

1. It can increase yield: all kinds of nutrient elements needed by crops in soilless cultivation are artificially prepared and applied into nutrient solution, and nutrients can be supplied scientifically according to crop types and different growth stages of the same crop, so crops grow and develop healthily. Strong growth.

2. The environment is clean and hygienic: soilless cultivation uses inorganic fertilizer, while soilless cultivation applies organic fertilizer, fertilizer decomposition and fermentation, which not only produces odor to pollute the environment, but also causes the egg breeding of many insect pests and harms crops, so soilless cultivation does not have these problems.

3. Water-saving, fertilizer-saving and labor-saving: soilless cultivation does not require ploughing, ploughing, weeding and other operations. Watering and topdressing is solved at the same time, and it is supplied regularly and quantitatively by the liquid supply system, which will not cause waste, and the management is very convenient, which greatly reduces the labor intensity.

4. Avoiding continuous cropping obstacles: soilless cultivation can avoid continuous cropping obstacles. Reasonable land rotation and avoiding continuous cropping in vegetable cultivation is one of the important measures to prevent serious occurrence and spread of diseases. Soilless cultivation fundamentally solves this problem.

5. free from soil restrictions: soilless cultivation makes crops completely out of the soil environment and is not limited by soil quality and water conservancy conditions. soilless cultivation can be used in many deserts, wastelands or areas where it is difficult to cultivate.

6. make full use of space: soilless cultivation can get rid of the constraints of the land, so it can not be restricted by space, and can use the flat roof of urban buildings to grow vegetables and flowers, virtually expanding the cultivation area, and can also be produced according to the will of people.
