Natural light utilization type plant factory system for factory production of vegetables

Abstract

The invention relates to a natural light utilization type plant factory system for factory production of vegetables. The system is characterized by comprising a seedling culture part taking artificial light as a plant light source and a cultivation part taking natural light as a plant light source, wherein the seedling culture part comprises seedling culture beds arranged in closed space, a seedling culture part nutritional solution preparation and circulating system connected with the seedling culture beds as well as an environment control system, and the seedling culture part nutritional solution preparation and circulating system comprises a seedling culture part circulating box and a seedling culture part solution distribution box; the cultivation part comprises cultivation beds, a cultivation part nutritional solution circulating system connected with the cultivation beds, a nutritional solution temperature control system, a light supplementing device and a cultivation part solution distribution box connected with the cultivation part nutritional solution circulating system. The cultivation part taking the natural light as the main plant light source is used as a main body and combined with the seedling culture part taking the artificial light as the plant light source, and year-round factory production of the vegetables without natural condition restriction is realized.

Description

technical field [0001] The invention relates to a plant factory system, in particular to a natural light utilization type plant factory system used for industrialized vegetable production, and belongs to the field of agricultural technology. Background technique [0002] The term "Plant Factory" was first proposed in Japan. Its concept covers facility gardening in a broad sense, while in a narrow sense it refers to artificial light-based plant production systems. According to the current situation of Japanese plant factories, plant factories are the general term for artificial light utilization type and natural light utilization type nutrient solution cultivation system. [0003] There are two main types of existing plant factory systems. One is the fully artificial light utilization plant factory under fully enclosed conditions. This type of plant factory has high investment and operation costs and low output. It is a conceptual equipment and does not have the potential for...

Problems solved by technology

[0003] There are two main types of existing plant factory systems. One is the fully artificial light utilization plant factory under fully enclosed conditions. This type of plant factory has high investment and operation costs and low output. It is a conceptual equipment and does not have the potential for large-scale production. conditions, it can only be used as a concept display to meet the needs of a small number of people to eat high-end hydroponic vegetables; the other is the traditional hydroponic greenhouse for vegetable production in natural light greenhouses using pipeline cultivation, deep liquid flow floating plate cultivation, etc. Plant factory, the seedling raising process of this kind of plant factory still adopts matrix seedling raising, which makes the production environment not clean enough, and it is easy to damage the roots when transplanting seedlings

Its environmental control is relatively rough. Due to the use of dozens of tons of nutrient solution, it not only wastes resources and pollutes the environment, but also cannot achieve precise control of the temperature, pH, and EC of the nutrient solution at a low cost, which is prone to plant diseases and insect pests. Uneven, relatively low output, uncontrollable production cycle, unable to meet the factory production requirements of high-end vegetables
