Mushroom spraying control method, device and system

Abstract

The invention provides a mushroom spraying control method, device and system, and the method comprises the steps: determining the growth projection area of each collection position according to a visible light image; determining the surface average temperature of the growth projection area in combination with the thermal infrared image and the growth projection area; determining a transpiration diffusion coefficient at the acquisition position according to the surface average temperature of the growth projection area and the environment temperature; according to the transpiration and diffusion coefficients at all the collection positions, the average transpiration speed of the to-be-operated fungus room is determined; and according to the average transpiration speed, a spraying strategy for all mushrooms in the to-be-operated mushroom room is formulated. According to the invention, physiological response is incorporated into a greenhouse control system, the spatial diversity of the transpiration rate of mushrooms in the space is fully considered, the transpiration rate of each collection position in the room is comprehensively considered, the determined average transpiration rate is used to carry out humidification regulation and control, and a humidification strategy based on the combination of the greenhouse environment and the growth and development law of mushrooms is constructed. And accurate and effective technical support is provided for spraying and water replenishing of mushrooms.

Description

technical field [0001] The invention relates to the technical field of crop environment automatic regulation, in particular to a mushroom spraying control method, device and system. Background technique [0002] Edible mushroom entities have the characteristics of crisp tissue and high water content. Because the surface layer does not have enough effective external structure to prevent water loss, a large amount of water will be lost due to transpiration. [0003] Mushrooms consume a lot of water resources during the fruiting stage. During the fruiting stage of mushrooms, especially after budding, if the air humidity is low at this time, the small mushrooms will wither and die due to the rapid evaporation of a large amount of water in the mushroom body; The flow and transport of nutrients are blocked, which will cause metabolic disorders, dysplasia, edema, yellowing and ulceration of the mushroom body. [0004] Most of the existing mushroom spraying strategies are based on...

Problems solved by technology

During the fruiting stage of mushrooms, especially after budding, if the air humidity is low at this time, the small mushrooms will wither and die due to the rapid evaporation of a large amount of water in the mushroom body; The flow and transport of nutrients are blocked, which will cause metabolic disorders, dysplasia, edema, yellowing and ulceration of the mushroom body

[0004] Existing mushroom spraying strategies are mostly based on methods such as timed spraying or setting the upper and lower thresholds of sensors. Such methods are relatively extensive and do not consider the water demand of mushrooms situation, it is impossible to fine-tune the spraying

[0005] In addition, in the existing methods of irrigation based on crop transpiration, there is a crop coefficient method for calculating the transpiration of vegetables, fields and other crops, but the determination of the crop coefficient is subject to Influenced by crop growth status and meteorological factors, and many years of experiments and verifications are required, resulting in large errors in estimation results

In addition, the photosynthetic system tester method commonly used on vegetables can only directly measure the transpiration of photosynthetic crops, but it cannot be applied to mushrooms.
