Technical Field

The invention belongs to the technical field of soilless culture seedling raising methods, and particularly relates to an intelligent soilless culture seedling raising method for plants.

Background

Soilless culture refers to a culture method in which water, grass carbon or forest leaf mold, vermiculite and other media are used as substrates for fixing plants, and the plant roots can directly contact with nutrient solution. The components of the nutrient solution in the soilless culture are easy to control and can be adjusted at any time. In places with proper illumination and temperature and no soil, such as deserts, beaches and barren islands, the method can be carried out as long as a certain amount of fresh water is supplied. Soilless culture is divided into hydroponic culture, fog (air) culture and matrix culture according to the difference of culture media. Hydroponics is a cultivation method in which the root system of a plant is directly contacted with a nutrient solution without using a substrate. The earliest hydroponics was to immerse the plant roots in nutrient solution for growth, which resulted in oxygen deficiency and death of the roots in severe cases. The water culture method of a nutrient solution membrane method is usually adopted, even if a layer of very thin nutrient solution layer continuously and circularly flows through the root system of the crop, the water and nutrient of the crop are continuously supplied, and the fresh oxygen of the root system is continuously supplied.

When the seedlings are cultivated by the conventional soilless culture seedling cultivation method, the solute of the nutrient solution is easy to deposit because the nutrient solution does not flow in the cultivation pot, bacteria are easy to breed, the growth of the seedlings is influenced, and the growth of the seedlings is influenced because the moisture of the seedling leaves cannot be preserved.
