Method and system for imitating luminous environment

Abstract

The invention discloses a method for imitating luminous environment. The method comprises the following steps: respectively confirming the light intensity of the light which influences the growth of crops in the spectrum of the actual luminous environment of the crops, and according to the corresponding relationship between the output power of a lamp and the light intensity, adjusting the output power of the lamp which can emit the light influencing the growth of crops. According to the method for imitating luminous environment provided by the invention, the lamp which can emit the light influencing the growth of crops is used as a light source, the light intensity of the light which influences the growth of crops is confirmed according to the spectrum of the actual luminous environment of the crops, and the output power of the lamp is adjusted based on the light intensity, thereby ensuring that the intensity of the light emitted by the lamp is accordant with the intensity of the light in the actual luminous environment and realizing the accurate imitation for the luminous environment. The invention also discloses a system for imitating luminous environment.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method and system for simulating a light environment. Background technique [0002] Intercropping is a planting method that uses the principle of biodiversity to plant two or more crops in the field at the same time. my country has a large population, the area of ​​cultivated land per capita is constantly decreasing, and intercropping is common, with an annual area of ​​more than 28 million hectares, which plays a key role in improving land utilization and increasing grain sowing area and output. A large number of studies have shown that intercropping of different types of crops not only improves the structure of crop groups, increases resource utilization, and enhances group stress resistance, but also reduces the amount of chemical fertilizers and pesticides used, while ensuring national food security and improving agricultural products. Its market competitiveness ...

Problems solved by technology

[0004] The traditional method of simulating the internal light environment of crop groups is to add one or more layers of green filter paper or shade nets under the fluorescent lamp. Although this method can change the spectral composition, it cannot adjust the light according to the actual spectral composition of different crop intercropping fields. Accurate simulation of the environment is difficult to meet the needs of intercropping intercropping physiological and biochemical mechanism and molecular mechanism research
