What crops can be grown in soilless culture, and what can be grown in soilless culture

It is used in the production of out-of-season and high-end horticultural products.

Soilless cultivation is used to produce clean, high-quality, high-grade, fresh and high-yield vegetable products, which are mostly used for off-season and long-season cultivation. For example: melons.

2.Crop production is carried out in deserts, barren beaches, reef islands, saline-alkali lands, etc.

Soilless cultivation can be used to produce vegetables and flowers in barren land that is not suitable for soil cultivation, such as sandy thin land, saline-alkali land, desert, reef island, and North and South poles.

3.Application in facility horticulture.

Soilless culture technology is widely used as an effective way to solve the obstacle of soil continuous cropping in greenhouse and other horticultural protection facilities, and is mostly used for cultivating cut flowers, potted flowers with herbaceous and woody flowers, its flowers are larger, the flower color is bright, the flowering period is long, and the fragrance is strong, especially in the family, hotels and other places soilless cultivation potted flowers are very popular.

4.Apply in the home.

The use of soilless cultivation in their own yards, balconies and roofs to grow flowers and vegetables, not only entertaining, but also have a certain ornamental and edible value, easy to operate, clean and hygienic, can beautify the environment.

5.Applications in space agriculture.

Soilless cultivation of plants to produce food in space is arguably the most effective method. Soilless cultivation technology is playing an important role in the research and application of aerospace agriculture.

Summary: Lettuce, out-of-season fruits melon, loofah, tomato, strawberry, flowers are all fine.

Soil cultivation involves a wide range of flowers and vegetables are not fully promoted: vegetables, chicory, kale, cabbage, rape, cabbage, cabbage, leaf mustard, kale, purple back sunflower, watercress, cress, celery, clover, amaranth, chives and potatoes See flowers: lily, monstera, Milan, Junlan, camellia, Yueji, jasmine, rhododendron, kumquat, Wanqing, violet, phalaenopsis, upside-down Admiralty, five-needle pine, campy banana, rubber fig, Brazilian iron, begonia, fern, palmaceae.

1. Soilless hydroponic vegetables: lettuce, rape, celery, beets, water spinach, leeks, garlic sprouts, amaranth, wuta-tsai cabbage, dwarf raw tomatoes, peppers, purple-backed geraniums, water spinach, leeks, garlic sprouts, lettuce, cherry radish, koji hemplo, endive, amaranth, apricot.

2. Soilless hydroponics: hydroponic vegetables refer to vegetables that most of the roots grow in the nutrient solution layer and only provide water, nutrients and oxygen to them through the nutrient solution, which is different from the vegetables cultivated in the traditional soil cultivation form, but some substrates may be used when raising seedlings.

3. Soak the seeds in about 20 years of clean water for 3-4 hours, drain the water and put them on a clean and moist gauze, and germinate in a 15-20 environment, and the seeds can be exposed in 2-3 days.

4. Lettuce should be cultivated in autumn, winter and spring, and the seeds should be sown in the planting cup containing fixes, such as vermiculite, etc., or in the seedling tray containing the seedling substrate, and each cup should be sown with 1-2 seeds, and covered with a layer of substrate after sowing. Then cover with shade nets, drench enough water, keep it moist, and wait for the seedlings to emerge. About 10 days before planting, the water should be properly controlled according to the seedling condition.

When the seedlings have 6-7 true leaves, the seedlings are planted in the nutrient bowl first, and then the seedlings are filled with vermiculite.

5. The formula of nutrient solution suitable for lettuce growth is (gram tons): calcium nitrate 621, potassium nitrate 444, trim potassium dihydrogen phosphate, magnesium sulfate 500, and ammonium nitrate 69. In the early stage of planting, due to the small size of the plant, the root system is not developed, so it can be deeper, the depth of the nutrient solution is kept at about 10 cm, and it is advisable to soak it to the bottom of the planting cup 1-2 cm, with the elongation and growth of the root system, the water level can be gradually reduced, and the liquid level will be reduced to 5-8 cm, so that a part of the root system is exposed to the air, so as to increase the opportunity for root oxygen absorption, promote root development and plant growth.

6. When the plants reach the harvesting standard, they should be harvested in time. The harvest period is different for different varieties and different cultivation seasons, and the growth period of non-bulbling lettuce is 60-90 days, and the growth period of bulb-bearing lettuce is 100-120 days.

Soilless cultivation can be planted water spinach, leeks, garlic seedlings, endive, amaranth, apricot, lettuce, rape, pepper, purple-backed geranium, oil lettuce, cherry radish, koji hemp cabbage, celery, sugar beet, wuta-ta cabbage, etc., soilless cultivation refers to the cultivation method of using water, peat, vermiculite and other substances as the substrate of plant roots, so that the root system of the plant is directly connected to the nutrient solution.

What plants can be grown in soilless culture.

1. Water spinach.

Soilless cultivation can grow water spinach, water spinach is also known as bracken, it is native to East Asia, and is now widely cultivated as a vegetable, when cultivating water spinach, the temperature of the environment needs to be controlled at about 15-25 degrees, which is conducive to better growth of plants.

2. Lettuce. Soilless cultivation can grow lettuce, lettuce is an annual or biennial herb plant, its leaves are obovate, can be eaten raw directly after washing, lettuce likes to be cool and cold, it is best to put it in a cool environment when breeding.

3. Celery burns hail.

Soilless cultivation can grow celery, celery belongs to the Apiaceae family, it is one of the vegetables commonly eaten in our country, so it has a long history of planting, if you want to grow celery, it is best to choose the autumn from September to October.
