Device and method for regulating and controlling density of soilless cultured plants of plant factory

Abstract

The invention relates to a device and a method for regulating and controlling the density of soilless cultured plants of a plant factory. The device comprises at least one culturing plate and at least two culturing units, wherein each culturing unit is provided with a culturing hole; each culturing plate is provided with a strip-shaped opening; the culturing units are erected on the strip-shaped openings and can move along the strip-shaped openings so as to regulate the interval; at least one additional culturing plate for regulating the interval between the culturing plates is arranged between the culturing plates; the culturing plates and the culturing units can be provided with matched guide rails for providing convenience for sliding. According to the device disclosed by the invention, each culturing unit moves along the strip-shaped opening of each culturing plate so as to regulate the planting distance; line spacing can be regulated by adding or reducing the additional culturing plates, so that the distance between the soilless cultured plants can be conveniently regulated; a culturing space can be saved; the utilization rate of electric energy of a light source can be increased.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation of plants, and in particular relates to a plant density control device and method for soilless cultivation in a plant factory. Background technique [0002] The plant factory is a highly intensive annual production facility. Through multi-stubble cultivation and three-dimensional multi-layer cultivation, the output is large and the quality is controllable. It is an effective production method to solve the effective supply of facility plant products such as facility vegetables and medicinal plants in my country. [0003] At present, plant factories usually adopt cultivation bed hydroponics cultivation. The position of the cultivation bed is relatively fixed, and the structure is U-shaped groove. The groove is covered with a light cover plate. The cultivation hole is customized on the cover plate, and the plant is fixed with a sponge block to make the roots go deep. Growth and productio...

AI Technical Summary

Problems solved by technology

Due to the fixed cultivation holes, in order to ensure that the plants have sufficient growth space in the later stage of growth, enough space must be reserved at the seedling stage, resulting in too large distance between plants at the seedling stage, which cannot be dynamically adjusted, and the space is seriously wasted.

Causes waste of valuable cultivation space in natural light plant factories and reduces production efficiency

In the artificial light plant factory, not only the cultivation space is wasted, but also due to the waste of light in the large area without seedlings, the utilization rate of artificial light source power is low, which does not meet the development goals of high-efficiency and energy-saving production in plant factories, and urgently needs to be improved.

However, if the distance between plants is adjusted by replacing the cover plates with different planting hole spacing, all plants need to be transplanted and replanted, which is a huge workload and difficult to implement in a plant factory.
