A plant microenvironment control device and method

Abstract

The invention provides a plant population microenvironment control device and method. The plant population microenvironment control device includes a box body, a first sensor box, and a dehumidification and cooling device vent. Through sensors in the first sensor box, a morphological structure of the plant population and environmental parameters in the box body are detected. Based on detection results, the light intensity, temperature and humidity in the box body are adjusted by using the functions of an electrochromic material covering the surface of the box body and a dehumidifier or an air-conditioning fan. The plant population microenvironment control device can achieve the precise control of the microenvironment of the plant population to be measured under the premise of ensuring thenatural growth of the crop population to be measured during the non-measurement, including light environment, temperature and humidity, etc., and at the same time, realize the measurement of the morphological structure, assimilation rate, light distribution and the like of the crop population.

Description

technical field [0001] The present invention relates to the technical field of agricultural informatization, and more specifically, to a device and method for controlling the microenvironment of plant populations. Background technique [0002] Environmental factors for plant growth include light, temperature, moisture, heat, nutrients and air, which are indispensable in plant life activities. In agricultural production and scientific research, high-yield and efficient production of agricultural crops is often achieved through the regulation of the above-mentioned environmental factors. Taking light as an example, the light environment is one of the important physical environmental factors that are indispensable to the growth and development of plants. It is an important technology in the field of agricultural informatization to control plant morphology through light quality adjustment; sunlight cannot be controlled, so artificial Supplementary lighting has been increasingly...

AI Technical Summary

Problems solved by technology

[0004] The artificial climate incubator is an indoor controllable light environment device, which is only suitable for experiments on tiny plants or early plant growth, and there is a certain difference from the actual growth conditions of crops in the field; the growth conditions of crops in the facility environment are still different from those of field crops. Large environmental differences, and due to the large environment of the facility, it is difficult to achieve high-precision environmental control of a certain micro-environment; a vertically open automatic canopy assimilation box can only realize the assimilation rate measurement of the plant population at a specified location, and its effect on light The environment cannot be controlled independently, and depends on the light transmission of the box material and the change of the natural light environment

Although there is a ventilation device on the upper part of the assimilation box, and the material of the box has high light transmittance, the plants in the box are still different from those in the natural environment in terms of light, temperature, moisture, ventilation, etc., and grow in the box for a long time The growth and development state will be affected to a certain extent, and there are certain differences from the growth of crops in the natural environment
