Description

Crop phenotyping is an emerging interdisciplinary field. The genome of crops is the internal cause, and the external environment during the growth process is the external cause. The interaction of internal and external factors together determines the appearance of the crop, that is, the phenotype. With the improvement of the efficiency of sequencing technology and the reduction of cost, crop genome data has been continuously improved, and the technology of automatic and intelligent regulation of the uniform distribution of different environmental elements in the process of crop growth is lagging behind, timely adjustment and uniform control of the temperature and irrigation in the greenhouse Environmental factors such as wind and wind can help us understand the growth status of experimental plants under controllable conditions, so as to screen and cultivate fine varieties and realize precision agricultural management.

At present, there are many equipment and devices that can be adjusted based on the growth environment of crops under greenhouse or closed conditions at home and abroad. European facility agriculture, represented by the Netherlands, mainly cultivates ornamental plants such as flowers and installs automation such as temperature, water vapor, and light. The control system, the device structure is complex, and the uniformity of temperature and light distribution is low. This mode cannot meet the requirements of crop growth in a scientific experimental environment. Most domestic plants adopt simple arch sheds for crop growth management and production. The adjustment of temperature or irrigation is mainly through pure manual labor. The degree of automation and intelligent control is low, and the uniform growth environment required by experimental plants cannot be achieved.

In summary, the existing greenhouse-based crop growth environment regulation system cannot satisfy the uniform control of multiple environments at the same time, and it is difficult to achieve a comprehensive and even distribution of environmental elements such as temperature, water, air, wind, and light in the greenhouse.
