Plant factory and plant culture method

Abstract

The invention relates to a plant factory and a plant cultivation method. The plant factory at least comprises a cultivation device configured to carry plants for plant cultivation, the cultivation device comprises at least one first track and a plurality of second tracks which are coaxially configured, the at least one first track is configured to be formed in a surrounding mode along a shaft body of the cultivation device, the curve surrounding radius of the first track in the extending direction from the remote end of the shaft body to the near end of the shaft body or the distance between the first track and the shaft body is continuously changed; the plurality of second tracks are configured to be distributed on the radial outer side face of the shaft body in a staggered mode based on arrangement in the first direction and / or the second direction, and the lengths of the plurality of second tracks distributed in the axial direction of the shaft body are different from one another when observed in the first direction; wherein the first track and the second tracks intersect with each other to form a plurality of staggered and adjacent planting parts for plant cultivation.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a plant factory and a plant cultivation method. Background technique [0002] Today, according to the conditions of the facilities and the control level of environmental factors in the facilities, the types of horticultural facilities mainly include plastic greenhouses, solar greenhouses, multi-span greenhouses and plant factories. The artificial light plant factory is internationally recognized as the highest stage of facility agriculture. It is a form of technology-intensive facility, and its core technologies include soilless cultivation technology, LED lighting technology and intelligent control technology. The artificial light plant factory has the advantages of being fully enclosed, having low requirements on the surrounding environment, shortening the plant harvest period, saving water and fertilizer, no agricultural production, and no waste discharge outside. ...

AI Technical Summary

Problems solved by technology

[0006]In existing plant factories, when cultivating plants, the plant cultivation frame often adopts a planar structure and a three-dimensional structure. The space makes the effective space above it unable to be fully utilized. At the same time, based on the planar structure, there are often a large number of supplementary light equipment used to assist plant growth. A large number of supplementary light equipment will undoubtedly increase the production cost. In order to solve this problem, existing technologies use When it comes to mobile light supplement equipment, mobile light supplement equipment cannot ensure that plants at various planting points in the planting area can receive light with appropriate proportions, appropriate intensity, and uniform illumination; as for the three-dimensional structure, although it can effectively increase the space utilization, but when irradiating with the corresponding supplementary light equipment, it is nothing more than to use the means of arranging light sources on each planting layer or setting up mobile supplementary light equipment that can move in the vertical direction based on the three-dimensional structure, but this is also the same There is a problem that there is a blind area in the light irradiation, and the light irradiation it can provide is not uniform

Secondly, when using supplementary light equipment to grow and irradiate plants, the design of the light source often adopts the method of combining light sources with different emission wavelengths or light colors according to a certain gap and independently driven by electricity, but it ignores the In actual irradiation, when light sources with different emission wavelengths are combined for irradiation, based on the distance difference between each planting point and the light source, the actual light that each planting point can receive is different, so a similar equidistant The method of arranging light sources in a different way cannot meet the light requirements of plants in different positions, that is, it cannot make each planting point receive effective and uniform light with appropriate intensity and reasonable proportion.
