Sunlight-type multi-layer tidal green leafy vegetable factory production system

Abstract

The invention provides a sunlight multilayer tide-type factory production system for green-leaf vegetables. The system comprises multilayer three-dimensional growth shelves, tide-type water storage disks, hole disks, a water return pool, a water inlet pipeline and a water return pipeline. The multilayer three-dimensional growth shelves are arranged in multiple rows. The tide-type water storage disks and the hole disks are all arranged on the multilayer three-dimensional growth shelves. The multilayer three-dimensional growth shelves in the sunlight multilayer tide-type factory production system for the green-leaf vegetables are divided into multiple irrigation groups. The water return pool comprises a return water precipitation region, a mother liquid region and a filtering interlayer, wherein the filtering interlayer is located between the return water precipitation region and the mother liquid region. The sunlight multilayer tide-type factory production system for the green-leaf vegetables has the advantages that illumination distribution is more scientific, three-dimensional cultivation is realized, and light supplementation by LED lamps is not needed; the growth shelves are controlled in a layered mode, so the problem of non-uniformity of water and fertilizer on all layers is solved; since a tide irrigation automatic control system is researched and developed, the temperature and humidity environment, the illumination intensity, the temperature and humidity of soil, PH and EC of a nutrient solution and other parameters of a greenhouse can be monitored in real time.

Description

technical field [0001] The invention relates to a solar-type greenhouse green leafy vegetable growing system in the field of agricultural technology, in particular to the integration of technologies such as optimized parameter design of growing racks, multi-layer adjustable non-equidistant spacing, layered controllable tidal irrigation, and automatic software management of water and fertilizer. Green leafy vegetable factory production system. Background technique [0002] At present, tidal irrigation systems in Europe and the United States mostly adopt single-layer planting methods. Japanese plant factories adopt multi-layer cultivation methods, which increase the planting area and output to a certain extent, but require LED lights as light sources for production. [0003] In 2008, Shanghai Jiaotong University invented the "multi-layer tidal irrigation seedling device, CN200810033992.2" according to the production needs of flower and vegetable seedlings. For the seedling pro...

AI Technical Summary

Problems solved by technology

[0003] In 2008, Shanghai Jiaotong University invented the "multi-layer tidal irrigation seedling device, CN200810033992.2" according to the production needs of flower and vegetable seedlings. For the seedling production of the lower layer of the device, due to insufficient light, LED lights are needed to supplement light, which increases energy consumption. Consumption and other issues

[0005] (1) The lower layer is shaded and relies more on fill lights, which increases energy consumption and capital investment;

[0006] (2) The layered control of the growth frame is not flexible enough, and the environmental control is poor; the planting of the plants on the growth frame cannot be reasonably configured according to the growth habits of the crops, and then layered management;

[0007] (3) Water and fertilizer management and regulation cannot be carried out according to the growth needs of crops, and the control system is not accurate enough
