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, b

Embodiment 1

[0025] Embodiment 1: a cultivation plate, at least two cultivation units

[0026] Such as figure 1 Shown, comprise cultivation board 10 and two or more cultivation units 20, cultivation board 10 is provided with strip opening 11, each cultivation unit 20 is erected on the strip opening 11, and can move along strip opening 11 ( The small arrow in the figure indicates the moving direction) to adjust the distance d. The cultivating unit 20 is provided with a cultivating hole 21 for accommodating the plant 30, and the cultivating unit 20 is provided with a sponge block for fixing the plant (plant).

[0027] Among them, in order to make the combination of the cultivation unit 20 and the strip-shaped opening 11 relatively tight and firm, and to facilitate sliding, it is possible to increase the guide rail structure that cooperates with each other, such as figure 2 structure shown. Guide rails can be provided on the two edges of the strip-shaped opening 11, and the cultivation un...

Embodiment 2

[0028] Example 2: At least two growing plates

[0029] Such as image 3 As shown, there are at least two cultivation boards in this embodiment (two in the figure), and at least one additional cultivation board 40 for adjusting the distance between the cultivation boards is provided between the cultivation boards. During use, each cultivation unit moves along the strip-shaped opening of the cultivation board to adjust the plant spacing, and by adding or reducing additional cultivation boards, and correspondingly reducing or increasing the number of cultivation boards 10, to adjust the row spacing.

Embodiment 3

[0030] Example 3: A soilless cultivation device comprising a cultivation bed

[0031] Such as Figure 4 Shown is the soilless cultivation device with adjustable plant density of this embodiment, including a cultivation bed 50, the cultivation bed 50 is a square groove or a U-shaped groove, and its upper edge covers the cultivation board 10, The cultivation unit 20 and the additional cultivation board 40 . Covering the additional cultivation board 40 in the gap between the cultivation boards 10 can make the cultivation bed form a relatively airtight space and reduce the evaporation loss of the nutrient solution in the cultivation bed.

[0032] Such as Figure 4 As shown by the middle arrow, the cultivation board 10 can slide or move on the cultivation bed 50 in this embodiment, and the row spacing of plants can be adjusted by the movement of the cultivation board 10 . The movement of the cultivation board 10 in this embodiment can be used in conjunction with the additional c...

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...
