Novel method for artificially simulating crop growth shade and humidity environment

Abstract

The invention discloses a method of a novel technology for artificially simulating a crop growth shade and humidity environment and particularly relates to a novel method for artificially simulating the crop growth shade and humidity environment. According to the method, on the basis of a steel frame greenhouse, power-driven sunshade nets are installed at the top and on the two sides of the greenhouse for controlling illumination in the greenhouse, a spraying system composed of a PPR pipe and a spray nozzle is erected inside the greenhouse for controlling humidity and temperature in the greenhouse, ventilation systems composed of gauzes and power-driven exhaust fans are installed in the middle portions of the two sides of the greenhouse and used for controlling the temperature and the carbon dioxide concentration in the greenhouse, and according to comparison of temperature, humidity and other meteorological data on agricultural environment monitors installed inside and outside the greenhouse, light controlling, humidifying, cooling and ventilating measures are taken, so that the shade and humidity environment which is remarkably different relative to local natural environment conditions is formed. The step that according to the comparison of the temperature, humidity and other meteorological data on the two agricultural environment monitors inside and outside the greenhouse, the corresponding light controlling, humidifying, cooling and ventilating procedures are adopted is the key. The shade and humidity environment is simulated through the method, and the method has the advantages of being wide in geographical adaptability and suitable for different types of crops needing shade-tolerance and humidity-resistance screening and improving shade-tolerance and humidity-resistance breeding efficiency.

Description

technical field [0001] The method relates to the simulation of the crop growth environment, that is, by artificially controlling environmental factors such as temperature, humidity and light for crop growth, a simulation method of a stressful environment for crop growth is formed. Background technique [0002] Southwest my country is located in the confluence zone of cold air from the north and warm and humid air from the southwest. It is hot and humid in summer and cloudy and foggy in spring and autumn. It is the area with the shortest sunshine hours and the worst light intensity in China. According to relevant meteorological data statistics, the annual sunshine hours in East China such as Beijing are about 2500h, and the annual average relative humidity is 50%; The annual sunshine hours are as long as 1700-2200 hours, and the annual average relative humidity in Guangzhou is about 77%. Guilin, Guangxi, which is located in the southwestern region, has an annual sunshine hour...
