Problems solved by technology

For the extremely important water supplement (irrigation) control in soilless cultivation, the existing systems mostly use fixed or rotating nozzles on the top of the operating room for humidity control. Although the cost is small, the control fineness is poor, and there are still some systems Set up a dense pipeline network and nozzles, and install nozzles on the upper end of each culture pot. This operation method is not conducive to installation and wiring, and the maintenance and use costs are high. Therefore, an intelligent and convenient soilless cultivation is required.

Embodiment 1

[0028] see Figure 1~3 , in an embodiment of the present invention, an intelligent soilless cultivation greenhouse system includes a sealed operation greenhouse 1 with a rectangular section, in which several groups of soilless cultivation units are arranged at intervals along the vertical direction, and the cultivation The unit includes a number of fixed mounting plates 7 and water tanks 2 arranged above the fixed mounting plates 7 for mobile water replenishment. The fixed mounting plates 7 are fixed and fixed in the operating greenhouse 1 at equal intervals horizontally. For the cultivation pot 5 for soil cultivation, a moving part 21 is installed above the fixed mounting plate 7, and both ends of the moving part 21 are slidably installed on the chute 3, and the chute 3 is fixed on the inner side wall of the operating greenhouse 1, so that The moving part 21 is also provided with an electric moving structure, the electric moving structure includes a motor, a transmission belt...

Embodiment 2

[0037] A control method based on the intelligent soilless cultivation greenhouse system of embodiment 1, comprising the following steps:

[0038] 1. Carry out the preparation of culture medium in culture pot 5 (its preparation is different according to the characteristics of different soilless culture plants, and it is mostly formed by mixed fermentation of raw materials such as animal manure and probiotics);

[0039] 2. Plant the plants into the corresponding cultivation pots 5, install the sliding door 8 and the slide plate 12 into the operating greenhouse 1, and set the corresponding humidity, light and temperature in the controller;

[0040] 3. Monitor the adjustment of intelligent water supply, nutrient solution, light and temperature in the intelligent soilless cultivation greenhouse system at the control end, and judge the maturity of the plants according to the pictures of the plants taken;

[0041] 4. Move the mature plants out of the operating greenhouse 1, and fill ...

Embodiment 3

[0043] see Figure 4 , on the basis of Embodiment 1, the embodiment of the present invention upgrades the functions of an intelligent soilless cultivation greenhouse system and its control method, specifically:

[0044] One side of the water tank 2 is also connected to an electrolyzed water device 19 through a connecting pipe 18. The electrolyzed water device 19 is provided with a water storage chamber and an electrode connected to a power supply. Hydrogen gas is generated by point decomposing water, and the hydrogen passes through the upper end of the electrolyzed water device 19. The exhaust port enters the operating greenhouse 1, forming a hydrogen-rich environment in the operating greenhouse 1, significantly increasing the plant growth rate and vitamin content, and improving the efficiency of soilless cultivation.

[0045] It should be noted that the power supply of the electrolyzed water device 19 and other electrical components can be a mobile storage battery. When the w...

Abstract

The invention discloses an intelligent soilless culture greenhouse system and a control method thereof. The intelligent soilless culture greenhouse system comprises a rectangular-section closed operating greenhouse; a plurality of groups of soilless culture units are arranged in the operating greenhouse at intervals vertically; each culture unit comprises a plurality of fixed mounting plates and awater tank arranged above the fixed mounting plates for replenishing water movably, the fixed mounting plates are fixedly arranged in the operating greenhouse at equal intervals horizontally, a plurality of culture pots are placed on the fixed mounting plates, moving members are arranged above the fixed mounting plates, the water tank is mounted at the upper end of the moving members, and the lower end of the water tank is provided with water outlets in the number equal to that of the culture pots on the fixed mounting plates. On the basis of the conventional system, the intelligent soillessculture greenhouse system completes humidity control for soilless culture intelligently and accurately, work of spraying water in large scope or laying of a great number of water pipes and nozzles inthe prior art is avoided, individual requirement from each cultured plant can be met by the same system, and soilless culture is developed to the higher intelligent stage.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to an intelligent soilless cultivation greenhouse system and a control method thereof. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the plant can directly contact the nutrient solution. The composition of nutrient solution in soilless culture is easy to control and can be adjusted at any time. Soilless cultivation is a new technology of crop cultivation developed in recent decades. The characteristic of soilless cultivation is to replace the soil environment with the artificially created crop root growth environment. It can not only meet the conditions of crops for nutrients, water, air, etc. The needs of these conditions should be controlled and adjusted to promot...
