Intensive resource recovering plant factory

Abstract

The invention discloses an intensive resource recovering plant factory, comprising an envelope structure and a purity of indoor plant cultivation units surrounded by the envelope structure. Each of the plant cultivation unit is in closed-end structure, is provided with a light source apparatus independently, and is communicates to a gas-liquid shared pipeline system respectively. The intensive resource recovering plant factory has the advantages that the resource utilization is improved significantly, the plant yield per unit area is increased, the product cost is lowered and the popularization and application of plant factory is promoted in a wide range through innovative improvements on the structure of the plant factory.

Description

Technical field [0001] The invention relates to a plant factory, in particular to a resource intensive use type plant factory. Background technique [0002] As an important way of producing fruits, vegetables and food in the future, plant factories have received widespread attention. With the continuous advancement of related technologies, innovations from multiple angles in the industry continue to promote the development and improvement of plant factories. At present, plant factories The innovations of the company mainly include several major development trends, such as: CN101057550A announced a "closed environment-controlled plant factory that fully utilizes artificial light". The main problem to be solved is to use the control system of network technology to automatically adjust the temperature of the plant factory. , Humidity, CO 2 Concentration, sunlight, wind direction, wind speed, etc.; CN1977586A announced a "mobile plant factory" that can be transported to different reg...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the above-mentioned development trend of plant factories pays more attention to automation, continuous production throughout the year and provision of green vegetables, space occupation, and convenience of use, etc., and has not been developed and improved to reduce costs and increase production. For a long time, due to Constrained by factors such as the application of artificial light, the dependence on the air conditioning system, and the construction of structural equipment, the construction and operation costs of plant factories have always been high, and the cost of products has been high and difficult. It is difficult to compete with traditional cultivation models, which is not conducive to the development of plant factories. Large-scale promotion and application

Although some technologies have played a role in energy saving to a certain extent, they are far from meeting the cost requirements for large-scale artificial light vegetable production in the future

[0004] The above-mentioned restrictive factors include, for example: most of the current plant factories are equipped with several cultivation racks, and the plants on the cultivation racks are exposed to the entire cultivation room surrounded by the enclosure structure. The cultivation space, temperature, CO 2 The utilization rate is very low, and the output per unit area is difficult to increase significantly. In order to increase the output, the only way to increase CO 2 Such a solution increases the production cost further:

[0005] Specifically, for space factors, in order to meet the needs of air flow, cooling and personnel operation, large gaps have to be left when arranging the cultivation racks, which wastes valuable cultivation area; for temperature factors, in order to control the suitable high-power air-conditioning device, which greatly increases the cost, and the indoor temperature changes drastically, which is not suitable for plant growth; for CO 2 Factors, in order to make the uppermost plant canopy can also achieve a more suitable CO 2 concentration, it is often necessary to apply a large amount of CO 2 , until the entire plant factory is filled, while CO 2 is denser than air, after a while CO 2 will gradually deposit below, and CO 2 The uneven concentration is not suitable for the consistent growth of plants. At the same time, the CO absorbed by plants 2 Also limited to the surrounding area of ​​the plant body, a large amount of unabsorbed CO 2 It is discharged into the air during cooling and ventilation, which not only wastes resources, but also causes a large amount of greenhouse gases to cause harm to the external environment of the plant factory.
