Description

Technical Field

[0001] The invention belongs to the technical field of sugarcane cultivation, and particularly relates to a device for treating sugarcane drought stress. Background Art

[0002] Sugarcane can be used for a variety of purposes, including sugar, energy, and feed. Its high photosynthetic capacity, adaptability, and high biomass make it a key cash crop in my country. Guangxi is my country's leading sugarcane-producing region, but 90% of the crop is grown on hilly, dry land without irrigation. Due to uneven rainfall and poor soil water retention, droughts of varying degrees occur annually. Consequently, drought has become a major limiting factor in increasing sugarcane production in Guangxi and across my country. Drought resistance testing in sugarcane is closely linked to sugarcane yield. Breeding drought-resistant sugarcane varieties and screening and identifying drought-resistant breeding materials are key approaches to addressing or mitigating the impact of drought on sugarcane production.

[0003] Sugarcane drought resistance testing usually uses barrel cultivation and water control as technical means, which can keep the test materials under the same soil and water conditions to carry out relevant index measurements. However, the traditional barrel cultivation device has the following defects: on the one hand, the roots between sugarcane varieties spread and become entangled, affecting the subsequent root data detection; on the other hand, the water replenishment and control are relatively rough and inaccurate, resulting in inconsistent water stress, affecting the accuracy of drought resistance evaluation. Therefore, based on the above defects, it is necessary to propose a better technical solution to solve the above technical problems.
