Problems solved by technology

[0004] The embodiment of the present invention provides a downward liquid supply bucket type fogging cultivation device, which aims to solve the problem that the existing bucket type fogging cultivation device supplies the nutrient solution to the plants through the upward pipeline, the downward pipeline returns the nutrient solution, and the upward supply The liquid pipeline is distributed above the cultivation bed. Due to the complicated distribution of supply pipelines in the space above the cultivation bed in the greenhouse, the sunlight is easily blocked by the pipeline, which in turn affects the healthy growth of plants.

Embodiment 1

[0033] Such as figure 1 with figure 2 As shown, a downward liquid supply barrel type fogging cultivation device includes a cultivation bed 1, a cultivation bed support base 2, a liquid supply system, and a return system. The cultivation bed 1 includes a plurality of side cultivation plates 11 and a lower bearing positioning plate 12. Such as image 3 with Figure 4 As shown, the lower load-bearing positioning plate 12 is provided with a fixing hole 121 and a configuration hole 122. The fixing hole 121 is set at the center of the lower load-bearing positioning plate 12, and the upper surface of the lower load-bearing positioning plate 12 is provided with fixed eaves 123; the cultivation bed supports The base 2 includes a support tube 21; the liquid supply system includes a liquid supply tube 31 and a spray device 32 that uniformly sprays the roots of plants on the cultivation bed 1. The spray device 32 is in communication with the liquid supply tube 31; the return system includes...

Embodiment 2

[0039] The technical solution is basically the same as that of the first embodiment, but the difference lies in: figure 1 As shown, the cultivation bed support base 2 also includes a circular bottom plate 22. The bottom plate 22 and the support tube 21 are integrally formed. The support tube 21 is fixedly connected to the middle of the bottom plate 22. The bottom plate 22 is provided with an extension to facilitate the extension of the return tube 42. In the hole 221, the return pipe 42 passes through the extension hole 221 to communicate with the return hole 433, and the lower surface of the return fluid transition tank 43 is connected to the upper surface of the bottom plate 22. The cultivating bed support base 2 is placed on the ground, the cultivating bed 1 is placed on it, and the branch liquid supply pipe 312 leading from the main liquid supply pipe 311 is placed in the support pipe 21. The support pipe 21 is the center of rotation of the cultivation bed 1.

Abstract

The invention belongs to the technical field of soilless culture, and particularly relates to a downgoing liquid supply bucket type aerial fog cultivation device. The downgoing liquid supply bucket type aerial fog cultivation device comprises a culture bed, a culture bed support base, a liquid supply system and a reverse-flow system. By arranging the liquid supply system at the downgoing position of the bucket type aerial fog cultivation device, and laying a liquid supply pipe and a reverse-flow pipe underground, firstly, a greenhouse utilizable space is enlarged, the area of perpendicular cultivation is further increased, a pipeline is effectively prevented from blocking sunlight, it is guaranteed that an liquid supply pipeline and an reverse-flow pipeline of an culture bed in a greenhouse are neatly laid, uniformity of illumination in the greenhouse is improved, and conditions are provided for optimization and improvement of an aerial fog cultivation pattern.

Description

Technical field [0001] The invention belongs to the technical field of soilless cultivation, and particularly relates to a downward liquid supply barrel type fogging cultivation device. Background technique [0002] Aerosol cultivation is a new type of cultivation method. It is a soilless cultivation technique that uses a spray device to atomize the nutrient solution into small droplets and spray it directly onto the roots of plants to provide the water and nutrients needed for plant growth. The crops are hung in a closed cultivation device, and the roots are exposed inside the cultivation device. The nutrient solution is atomized by the spray device and sprayed onto the root surface to reduce the nitrate content of cultivated plants. It can double the yield of crops. It is an agricultural high-tech that does not use soil or substrate to cultivate plants. Because it replaces the soil environment with the artificially created crop root environment, it can effectively solve the dif...
