What are the common soilless plants?

Soilless cultivation is a modern seedling raising technology, which can make plant roots come into contact with nutrient solution directly. at present, it can cultivate both vegetables and flowers, but at present, soilless cultivation technology has not been fully popularized. What are the common soilless cultivation plants?

Common soilless plants

1. Common soilless vegetables are lettuce, chicory, kale, cabbage, rape, Chinese cabbage, bolting, big leaf mustard, kale, purple sunflower, watercress, celery, clover, amaranth, chives, potatoes and so on.

two。 Common soilless cultivation of flowers are: lily, tortoise back bamboo, Milan, gentleman orchid, camellia, rose, jasmine, rhododendron, kumquat, evergreen, violet, Phalaenopsis, inverted Admiralty, five-needle pine, Camptotheca, rubber banyan, Brazilian iron, begonia, ferns, palms and so on.

2. What are the categories of soilless cultivation?

Soilless cultivation has many advantages compared with soilless culture. at present, the area of soilless cultivation is increasing in a straight line, and soilless cultivation is becoming more and more extensive. at present, soilless cultivation can be divided into three types: water culture, rock wool culture and substrate culture.

1. Hydroponic culture: hydroponic culture is a method in which plant roots are in direct contact with nutrient solution and do not use substrate. The current hydroponic culture uses a very thin nutrient solution. It circulates through the plant roots. Ensure a continuous supply of crop water and nutrients, but also provide sufficient oxygen to the root system. The isolation of roots and soil can effectively avoid soil-borne diseases and do not need to carry out soil disinfection.

two。 Fog culture: spray culture is to compress the nutrient solution into an aerosol and spray directly onto the root system of the crop, which is suspended in the space of the container, usually with polypropylene foam board, which is drilled at a certain distance to cultivate crops in the hole. The two foam plates are diagonally set up into a triangle to form a space, and the liquid supply pipeline passes through the triangular space. Spray every 2 to 3 minutes, and the nutrient solution is recycled. However, the equipment requirements are very high, but also to consume a lot of electricity, can not be produced in a large area.

3. Substrate cultivation: substrate cultivation is the largest way to promote soilless cultivation, which is to fix crop roots in organic or inorganic substrate and supply nutrient solution through drip irrigation or trickle irrigation. The matrix can be packed into a plastic bag or laid in a trough, and the nutrient solution is not recycled, which is called an open-circuit system.

What are the advantages of soilless cultivation?

1. Because water can evaporate freely, it plays a more obvious role in regulating air humidity than plants cultivated in pot soil in the same environment.

two。 Water-raised plants can omit some management work of basin soil, clean and hygienic, and easy to maintain.

3. Such as the selection of some roots can be exposed to the light of the plant, coupled with a suitable container, the whole plant can be ornamental, with higher ornamental value.

At present, soilless cultivation is more and more widely used, and the price of soilless vegetables and flowers in the market is higher than ordinary ones. If there are conditions, you can try soilless cultivation.
