A kind of leek aerosol cultivation device

Abstract

The invention discloses an aerosol cultivation device for leek, which comprises a bottom plate (1), and a first side plate (2) and a second side plate (3) are respectively fixed by vertical welding at the two edges of the bottom plate (1). , the bottom plate (1) is welded with the first side plate (2) and the second side plate (3) to form a cultivation pool with an opening on the top surface, and the height of the second side plate (3) is slightly higher than The height of the first side plate (2), a positioning strip (4) arranged along the length of the first side plate (2) and the inner side surface of the top of the second side plate (3) is welded respectively. Above the cultivating pond, several cultivating boxes (5) are arranged side by side, and the cultivating boxes (5) are filled with a cultivating substrate mainly composed of vermiculite and river sand for cultivating leeks. The invention has a simple structure, is especially suitable for the planting of chives after annual growth, prevents the phenomenon of poor growth and rotten roots during the alternation of new and old root systems, and improves the economic benefit of planting chives.

Description

Technical field [0001] The present invention relates to the technical field of vegetable planting equipment, and is specifically involved in a leek gas mist cultivation apparatus. Background technique [0002] As a new type of cultivation, although it is very good to solve the problem of local diseases such as the, due to the low oxygen in the hydroponic nutrient, the temperature in spring, summer, autumn is higher than 15 ° C. The season, it is easy to cause hypoxia, and the phenomenon of weak leek is weak, the rotten root is caused, causing hydroponic leeks to death; aerosol cultivation, can be placed in an air fog environment, plant directly absorbed Atomized nutrient particles on the roots to meet growth, effectively solve the contradiction between water culture, air, nutrient supply, but in the actual application process, the roots of leeks will have a certain degree of corruption, the main reason It is the root of the leek, which is the string of the string, and the main ro...

AI Technical Summary

Problems solved by technology

Generally, the average physiological lifespan of leek roots is 1.5 years. It is not difficult to see that the roots of leeks have the characteristics of wide distribution, dense interweaving, and alternate growth and death of roots. The main reason for the poor growth is that the old root system has reached a height of 30-50cm at this time, and the new root system has just begun to grow, and the dense old root system will block the contact of the nutrient solution with the new root system. The applicant once tried to increase the growth rate. The pressure of the pump and the uninterrupted spray make the nutrient solution contact with the new leek root system, so as not to affect the growth of the leek during the root replacement period. However, after a period of experimentation, the students found that the leek began to have a large area of ​​rotten roots. The main reason is that the uninterrupted contact of the old roots with the nutrient water mist and the normal death of the old roots accelerated the decay of the old root system. After a large number of intertwined old root systems decayed, the fungus infected the new root system, and a series of chain reactions appeared.
