Water-culture potting bucket for analyzing influence of temperature increase on distribution state of wheat roots

Abstract

The invention provides a water-culture potting bucket for analyzing the influence of temperature increase on the distribution state of wheat roots. A multi-layer and porous interlayer stainless steelplate for positioning the growth of the wheat roots is arranged at the bottom of each layer of a wheat potting bucket with the opened upper part, a slicer is arranged in an inner layer of the interlayer stainless steel plate, and a culture water body on each layer can be blocked after the wheat roots are cut off; a controllable faucet is further communicated to the bottom of each layer of the potting bucket and can be used for collecting root exudates; and a visual tank body is used for cultivating a gel matrix and is provided with (longitudinal and transverse) gel culture observation rules for measuring the space distribution of the wheat roots in situ. Disc-shaped waterway reflux heating pipe units are arranged on the peripheral side walls of each layer of the potting bucket. By arranging the wheat potting bucket, the water-culture temperature of a growth environment of to-be-tested plants can be accurately controlled, the root exudates on the different layers can be collected, and in-situ observation of the root distribution can be realized; and the accuracy of test data is increased, and the intensive space and the convenient and rapid operation can be realized.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a hydroponic pot planting device used for researching and analyzing the influence of warming on the growth and distribution of wheat roots. Background technique [0002] With the change of global climate, global warming has become an increasingly serious problem. According to the fourth assessment report of IPCC (2007), the global average temperature has increased by 0.56℃-0.92℃ in the past 100 years, and the global temperature will increase by 1.8℃-4.0℃ by the end of the 21st century (IPCC, 2007). The National Assessment Report on Climate Change pointed out that in the past 100 years, China's annual average surface temperature has increased significantly, with a temperature increase of about 0.5-0.8°C, slightly higher than the average global warming rate (0.6±0.2°C) over the same period. The global temperature increase in recent years has brought new challenges and opportunities...

Problems solved by technology

Since most of the warming devices commonly used in the market are for warming the air, there are few mature products for warming hydroponics. Even with simple hydroponics warming equipment, it is impossible to truly simulate the temperature rise of hydroponics. High spatial differences; almost all heating devices are heated independently. Due to the limitation of the temperature control unit, it is impossible to ensure that the temperature rise between differe
