Description

A drawer-type potting bucket for analyzing the effect of increasing temperature on the distribution state of wheat roots

technical field

The invention relates to the field of crop cultivation, in particular to a potted device for researching and analyzing the influence of temperature increase on the growth and distribution state of wheat roots.

Background technique

As the global climate changes, global warming has become an increasingly serious problem. The fourth assessment report of IPCC (2007) shows that the global average temperature has increased by 0.56°C-0.92°C in the past 100 years, and the global temperature will increase by 1.8°C-4.0°C by the end of the 21st century (IPCC, 2007). The "National Assessment Report on Climate Change" pointed out that China's annual average surface temperature has increased significantly in the past 100 years, with a temperature rise of about 0.5-0.8°C, which is slightly higher than the global average temperature increase (0.6±0.2°C) during the same period. The increase in global temperature in recent years has brought new challenges and opportunities to scientific research. The growth of wheat requires a suitable temperature. As the global climate warms, the yield of wheat will be greatly affected. Various studies have inconsistent results on whether wheat yield increases under warming, especially less research on soil warming. How to study the root growth of wheat under soil warming and high temperature environment has always been a difficult problem in this field. In the process of scientific research, how to solve soil warming in a real and energy-saving manner, using simplified and precise tools has received more and more attention. more attention. Existing warming devices only increase the air temperature, and cannot study the influence of warming on the root system of wheat well. The growth of the root system will also greatly affect the growth of wheat, so the experimental data obtained are not accurate enough. There are very few experiments on soil warming, but the equipment is relatively simple, and there is no special soil warming equipment. In view of the particularity of wheat as a close-planted crop, and the root environment has a great impact on wheat, it is necessary to develop a device specifically for wheat soil warming. Since most of the commonly used warming devices on the market heat the air, there are few mature products that heat the soil. Even with simple soil warming equipment, it is impossible to truly simulate the space for soil temperature rise. 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 soil warming 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. Various problems will arise in the management and negotiation with manufacturers of products.
