A field automatic box-type passive heating device and test station

Abstract

The invention provides a field automatic box-type passive warming device and a test station, which are used for simulating the ambient temperature of a measured target object. Radiation passive temperature; a window is provided on the side wall of the incubator; an environmental monitoring system, at least including: a radiation sensor and a temperature sensor; The opening area is controlled to realize the automatic adjustment of the internal temperature of the incubator. The control system is connected to the environmental monitoring system in communication, and the opening area of ​​the window is controlled according to the monitoring information of the environmental monitoring system to realize the internal temperature adjustment of the incubator. Passive warming is carried out through sunlight radiation, and the opening area of ​​the window is controlled to realize the adjustable and controllable temperature inside the warming box, so that the internal temperature of the warming box is in line with the growth process of crops, which can truly simulate the atmospheric warming process.

Description

technical field [0001] The invention belongs to the technical field of plant field scientific experiments, in particular to a field automatic box-type passive warming device and a test station. Background technique [0002] Since the Industrial Revolution, the increase in the concentration of greenhouse gases in the atmosphere has caused the global average surface temperature to rise by about 0.74°C, and the global surface temperature will increase by 1.1 to 6.4°C by the end of the 21st century. Climate warming indirectly or directly affects the physiological and biochemical processes of plants in various ways, and further leads to changes in biomass accumulation and distribution patterns. Relevant research results show that global warming can not only indirectly affect plants by increasing the rate and availability of soil nitrogen mineralization, reducing soil moisture, and prolonging the growing season, but also directly by altering plant photosynthesis and respiration. ...

Problems solved by technology

[0004] For the research on the impact of climate warming on crops, a large number of warming simulation experiments have been carried out at home and abroad, and the impact and benefits caused by different heating devices are obviously different.

For example, White et al., Kimball et al., Wang Heling et al., Tan Kaiyan et al. selected an open infrared heating device to set a constant temperature and placed it above the crop canopy, and the internal temperature of the canopy was raised through downward infrared radiation heat, and then studied the effect of temperature rise on crops. However, the temperature increase of this device is maintained by electricity. The higher the temperature increase, the higher the cost of electricity consumption. In addition, the temperature gradient formed by this device at the top of the crop canopy may have an impact on the crops.
