Automatic box-type passive temperature increasing device for field and test station

Abstract

The invention provides an automatic box-type passive temperature increasing device for a field and a test station. The device is used for simulating the environment temperature of a tested target object, and comprises a temperature increasing box, an environment monitoring system and a control system, wherein the temperature increasing box covers the tested target object and radiates the passive temperature through sunlight; a window body is arranged on the side wall of the temperature increasing box; the environment monitoring system at least comprises a radiation sensor and a temperature sensor; the control system is in communication connection with the environment monitoring system, controls the opening area of the window body according to monitoring data of the environment monitoring system so as to achieve automatic adjustment of the temperature in the temperature increasing box. Passive temperature increasing is carried out through solar radiation, the opening area of the window body is controlled, so that the internal temperature of the temperature increasing box is adjustable and controllable, the internal temperature of the temperature increasing box conforms to the growth process of crops, and the atmospheric temperature increasing process can be truly simulated.

Description

technical field [0001] The invention belongs to the technical field of plant field scientific experiments, and in particular relates 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 atmospheric greenhouse gases has caused the global average surface temperature to rise by about 0.74°C, and the global surface temperature will rise by 1.1-6.4°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 have an indirect impact on plants by increasing the mineralization rate and availability of soil nitrogen, reducing soil moisture and prolonging the growing season, but also directly change the plant's growth rate by changing t...

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.
