Plant growing rack with large planting space and high light energy utilization rate and application method of plant growing rack

Abstract

The invention relates to a plant growing rack with a large planting space and high light energy utilization rate and an application method of the plant growing rack. The plant growing rack comprises rack bodies and is characterized in that each rack body is transversely provided with a first growing area, a second growing area, a third growing area and a fourth growing area which are arranged at intervals, each growing area is provided with a culture mechanism inside, each culture mechanism is provided with a plurality of detachable planting strips or planting blocks which are arranged at intervals, and the intervals among the planting strips or the planting blocks increase gradually along with the growth of plants to maximize the space utilization rate during plant growth. An LED light source is correspondingly arranged above each culture mechanism, the illumination range of the LED light source is consistent to a plant leaf expansion range, and the light intensity, light quality, illumination time and heights between lamp beads and plant canopies of the LED light source are adjustable. The plant growing rack is simple in structure and beneficial to the increasing of the planting space and the light energy utilization rate.

Description

Technical field [0001] The invention belongs to the field of facility agriculture, and particularly relates to a plant growth frame with high planting space and light energy utilization rate and a use method thereof. Background technique [0002] Plant factory technology based on artificial light has developed rapidly in my country and has achieved remarkable results, and has gradually moved from laboratory to market-based production. On the one hand, plant factories can ease the tension on agricultural land, and at the same time reduce the input of chemical fertilizers, avoid the abuse of pesticides and plant hormones, and increase food safety; on the other hand, relying on advanced industrial design concepts and recognition of plant growth laws It is known that while improving plant production efficiency, it can also ensure the excellent quality of agricultural products. The light cultivation system is the main facility for plant factory production, and integrates a controllab...

AI Technical Summary

Problems solved by technology

[0004] First, the planting space is seriously wasted

The interval between the plants in the existing plant growth frame is all invariable from the seedling stage to the mature stage. This interval is often the required interval between two plants when the plant is mature, but this interval is too large for the seedling stage plants. , Excessive spacing causes a waste of planting space, and because most of the existing light panels are uniform light panels with evenly distributed light sources or uniformly arranged light strips, the planting space is wasted and light energy is also greatly wasted

[0005] Second, the waste of light energy is serious

When plants are in the seedling stage, the height of the plants is low, the volume is small, the required light intensity is low, and the light area is small. According to the arrangement of the existing light panels, the actual light receiving area of ​​the plants will be much smaller than the area covered by the light source, thus cause a lot of waste of light energy

[0006] Third, the existing plant light source layout is seriously homogeneous, and the light quality cannot be adjusted according to different stages of plant growth.

Different growth stages of plant cultivation have different requirements for light quality, and the homogeneous light source arrangement cannot give full play to the best effect of light, resulting in unnecessary waste of light energy and increased production costs
