Description

High-flux culture device for identifying plant root system penetration capacity Technical Field The utility model relates to the technical field of plant root box test equipment, in particular to a high-throughput culture device for identifying plant root system penetration capacity. Background In recent years, with the popularization and application of few and no-tillage technologies, the improvement of agricultural mechanization level, the increase of the number of agricultural machinery and the load, the compaction of farmland soil is becoming larger and larger, and the phenomenon of soil hardening is becoming more and more common. Compaction affects the soil structure, increases the mechanical resistance of the soil, prevents root system growth, reduces the number of root systems, changes the shape and growth direction of the root systems, and limits the acquisition of the root systems to soil moisture and nutrients. Penetration capacity is an indicator of the ability of a plant root system to penetrate soil, with penetration decreasing with increasing compaction of the soil. Numerous studies have shown that crop varieties with different root traits have different adaptability to environmental stress. Therefore, optimizing the root system character and function, and breeding excellent crop varieties with different root system penetration capacities is important to adapt to the actual demands of the current agricultural production. The traditional root system research method, such as an excavating method, a root drilling method, a root window method and the like, is time-consuming and labor-consuming, and can greatly damage the structure, the form and the like of the root system in the root system sample treatment process, so that a large error is easy to appear in a research result, and a complete plant root system sample cannot be obtained, thereby greatly limiting the development of root system research work. In the indoor research work, a water culture method, a mist culture method, a mesh bag method and the like are mostly adopted to develop root system research work. Although compared with the traditional field research method, the method can obtain a complete root system sample, the morphological configuration characteristics of the plant root system grown under the conditions of the methods are greatly different from the growth conditions of the plant root system in soil, and the growth conditions of the plant in the soil cannot be truly reflected, so that the research result has a certain deviation from actual field measurement and application. Disclosure of utility model The utility model provides a high-flux culture device for identifying the plant root system penetration capacity, which solves the defects in the prior art, can quickly obtain a complete root system sample on the basis of ensuring the true growth of plants, can accurately determine the plant root system penetration capacity, and is suitable for batch screening of multiple varieties of crops. Meanwhile, the high-flux culture device can also be used for researching adverse stress reactions of root systems on soil mechanical compaction, moisture, nutrients and the like, meets and adapts to the operation requirements of agricultural production, and achieves the purposes of scientific planting and crop yield assurance.
