Multi-linkage roller type center light supplementing nutrient solution cultivation device for plant factory

Abstract

The invention discloses a multi-linkage roller type center light supplementing nutrient solution cultivation device for a plant factory. The multi-linkage roller type center light supplementing nutrient solution cultivation device comprises a mounting frame body, a controller for controlling operation of electronic devices in the cultivation device and nutrient solution adding equipment. According to the multi-linkage roller type center light supplementing nutrient solution cultivation device for the plant factory, the roller planting device is adopted to replace a cultivation tray, the space utilization rate is greatly increased, the light source assembly is located in the roller planting device and can supplement light to all plants on the roller planting device at the same time, light energy is fully utilized, and the light utilization rate is increased. The system is more energy-saving and environment-friendly, meets the requirements of plants, avoids the influence of excessive nutrient solution on the plants, makes full use of the nutrient solution, can realize automatic addition of the nutrient solution, automatic light supplement and automatic immersion of the plants into the nutrient solution, does not need a large amount of labor in the whole process, saves manpower, and is high in input-output ratio. And a better use prospect is brought.

Description

Technical field [0001] The invention relates to the field of plant planting, and in particular to a multi-linkage roller-type central light-filling nutrient solution cultivation device for plant factories. Background technique [0002] Traditional plant factories all use a shelf structure. Culture trays are placed on the shelf structure, and light-emitting components are installed above the culture trays. This device has obvious defects when used; [0003] 1. Due to the limited space for plant development, only a small number of plants can be planted on each tray, and the overall space ratio is relatively low; [0004] 2. Light shines from above to promote photosynthesis of plants. Each layer of the shelf structure needs to be installed with lights, resulting in a large loss of lighting consumables and electricity consumption; [0005] 3. There is a nutrient solution tray at the bottom of each tray. The plant roots are constantly soaked, which wastes nutrient solution. More...

AI Technical Summary

Problems solved by technology

[0003] 1. Affected by the plant development space, only a small amount of plants can be planted on each tray, and the overall space rate is relatively low;

[0004] 2. The light is illuminated from above to promote the photosynthesis of plants, and each layer of the frame structure needs to be installed with lights, resulting in a large loss of lighting consumables and electricity consumption;

[0005] 3. There is a nutrient solution tray at the bottom of each tray. The plant root system is soaked from time to time, which wastes the nutrient solution, and the nutrient solution soaking time is too long to affect the respiration of the plant root system, which will have a negative impact on the plant;

[0006] 4. The fertilizer addition and light supplement in the process of plant cultivation all need to be manually operated, which wastes a lot of manpower and has a low input-output ratio;
