A wheat field simulated comprehensive temperature increase test device

Abstract

The invention relates to a comprehensive wheat field simulation temperature increasing test apparatus. The comprehensive wheat field simulation temperature increasing test apparatus comprises a temperature increasing box with the top and the bottom being opened, wherein water route backflow heating sheet units are arranged on the wall of the temperature increasing box, the water route backflow heating sheet units (20) are communicated with one another in an end-to-end manner and are distributed along the circumferential direction of the temperature increasing box (10), a hot water inlet of the water route backflow heating sheet (20) disposed on the head end is communicated with a hot water outlet of a heat exchanging unit arranged in a splitting manner, a hot water outlet of the water route backflow heating sheet (20) disposed on the tail end is communicated with a water returning opening of the heat exchanging unit. By adopting the temperature increasing box, the atmosphere temperature increase can be truly simulated; the temperature increasing box increases the temperature by virtue of the water route backflow heating sheets, and the temperature of a growth environment of a plant to be tested can be accurately controlled, so that the accuracy of test data can be improved, and an energy-saving purpose can be achieved.

Description

technical field [0001] The invention relates to the technical field of research engineering equipment such as environment and soil temperature, in particular to a field simulation comprehensive temperature increase test device with energy saving, high work efficiency, small occupied space and stable temperature increase. Background technique [0002] With the increase of greenhouse gases in the global environment, the ambient temperature is gradually increasing. According to the 2007 report of the United Nations Intergovernmental Panel on Climate Change (IPCC), the global average temperature has increased by 0.56-0.92°C in the past 100 years. It is expected that in the 21st century It will still rise by 1.4-5.8°C. China's land temperature will increase by 2.5°C every 100 years. In the past 50 years, the average surface temperature in my country has increased by 1.11°C, which is higher than the global level in the same period. The increase in temperature in winter and spring...

Problems solved by technology

Due to the commonly used heating devices on the market, some are closed heating devices, which cannot simulate the real atmospheric environment well; some devices are single heating sources, such as far infrared heating, blackbody lamp heating, and resistance wire heating , due to the whole growth period temperature increase or periodic long-term temperature increase, the energy consumption is too high, and the temperature increase is not uniform enough, and the temperature cannot be increased slowly; Due to its own limitations, it cannot guarantee the uniformity of temperature increase among different devices; the separate electric heating and solar heating sources can be managed in a closed manner to prevent the unsafe use of electricity for outdoor heating

Imported products are expensive and cannot be widely promoted in the country, thus reducing the popularity of the product. At the same time, in terms of product maintenance, it is not easy to manage and negotiate with manufacturers.
