Plant factory system

Abstract

The invention relates to a plant factory system. The plant factory system comprises a plurality of cultivating planting brackets which are arranged in a clean room, wherein each cultivating planting bracket comprises a cultivating frame (1) which is arranged in a multilayer architecture manner; each layer of each cultivating frame (1) is provided with a grooved cultivation structure (2); every two vertically adjacent grooved cultivation structures (2) are communicated through a water falling structure (4); the water falling structure (4) is alternately positioned at the left end and the right end of the every two vertically adjacent grooved cultivation structures (2); the lowermost grooved cultivation structure (2) is communicated with a liquid storage pond (5.1), which is positioned below the lowermost grooved cultivation structure, through the water falling structure (4); the liquid storage pond (5.1) is communicated with the uppermost grooved cultivation structure (2) through a circulating pump. The plant factory system provided by the invention has the advantages that the occupied area is small, the water consumption is less, the filtering is timely, liquid is fed in a flowing manner, air is supplied by the system, and the lighting is sufficient.

Description

Technical field [0001] The invention relates to a factory system, in particular to a factory system for planting plants using soilless culture technology, and belongs to the technical field of plant soilless culture. Background technique [0002] At present, with the reduction of land resources, the decrease of arable land area, and the long-term pressure of population increase, the planting industry is under increasing pressure, which forces agricultural technicians to study soilless cultivation techniques to reduce the demand for land For this reason, some companies have developed "a plant factory" disclosed in Chinese patent 201210158630.2, "resource intensive utilization plant factory" disclosed in 201210592579.6 and "a smart miniature sterile plant factory" disclosed in 201410607569.4; these technologies The use of soilless culture to plant plants (grain, vegetables, flowers, etc.) in factory, thereby reducing dependence on land, and helping to solve the huge demand for food...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many deficiencies in the operation of the above-mentioned plant factories: 1) the space utilization rate is not high, and a large floor area is still required; Consumption of water resources, and more water increases the weight of the cultivation tank structure, so that the supporting platform needs to have higher strength and load-bearing capacity, which invisibly increases the input cost; 3) Lack of effective and reliable Impurities and waste generated during the cultivation process cannot be filtered out in time, thereby reducing the absorption of nutrient solution by plants, and after a long period of operation, it needs to be shut down regularly for comprehensive cleaning, which is time-consuming and labor-intensive; 4) For cultivation tanks The liquid supply is directly pumped in, lacking water flow, which is not conducive to the absorption of nutrient solution by plants; 5) The lighting system adopts direct irradiation, and a large amount of light is scattered to the outside, so that the utilization rate of light is low, and the light height, The angle cannot be adjusted, which makes it impossible to create the most suitable lighting conditions when planting different plants; 6) The lack of a corresponding wind circulation system cannot simulate the wind blowing effect in nature, so that the leaves will not grow during the growth of the plants. Shaking, affecting its transpiration effect, is not conducive to its growth; therefore, the industry urgently needs a plant factory system that can solve the above problems, so as to facilitate large-scale and industrialized planting of plants, so as to relieve the pressure on the land
