Hydroponic potted bucket for analyzing the effect of warming on the distribution of wheat roots

Abstract

The invention provides a hydroponic potted plant bucket for analyzing the influence of temperature increase on the distribution state of wheat roots. The bottom of each layer of the wheat planting bucket with an upper opening is provided with a multi-layer porous interlayer stainless steel plate for the growth and positioning of the wheat root system. The interlayer stainless steel plate The inner layer of the board is equipped with a cutter, which can block the culture water body of each layer after cutting off the wheat root system; the bottom of each layer of the potted barrel is also connected with a faucet, and the controllable faucet can be used for the collection of root exudates; the visible box body It can be used for gel matrix cultivation, and is equipped with a gel cultivation observation ruler (longitudinal and transverse), which can measure the spatial distribution of wheat roots in situ. A disc-shaped water circuit return heating pipe unit is arranged on each layer of the circumferential side wall of the potted plant bucket. The invention can accurately control the hydroponic temperature of the growth environment of the plant to be tested, collect root exudates from different layers, and observe the root distribution in situ by setting the wheat potted barrel. Improve the accuracy of test data, and achieve the purpose of space-intensive and convenient operation.

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 increasing global temperature in recent years has brought new challenges and opportuniti...

AI Technical Summary

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 different heating devices reaches a consistent level

At the same time, no suitable hydroponic heating equipment has been found in the world. Even if there is, the high price of imported products from abroad cannot be widely promoted and applied in China. Therefore, the popularity of the product cannot be improved, and the maintenance of the product is also inconvenient. Various problems will arise in the management and negotiation with manufacturers of foreign products
