Description

Technical Field

[0001] The utility model relates to the technical field of potato breeding, in particular to an adjustable seedbed for potato breeding. Background Art

[0002] Potatoes are the world's fourth-largest food crop, boasting both high nutritional and economic value. They are a crucial agricultural product for ensuring food security and increasing farmers' incomes. High-quality varieties are the core driving force behind the development of the potato industry, and efficient and precise breeding techniques are crucial for selecting superior varieties. In recent years, soilless cultivation techniques, such as hydroponics and substrate culture, have gained application in breeding research due to their advantages, including environmental control, space savings, and ease of refined management.

[0003] The authorization announcement number is: CN217986276U, which announced an adjustable seedling bed for potato breeding. The seedling bed uses a motor to drive the screw to rotate to achieve the left and right movement of the mixing plate, while driving the culture medium liquid in the liquid hopper to perform preliminary rotation and mixing to prevent the insufficiently mixed culture medium liquid from directly entering the box body and causing uneven reaction. The reciprocating motion of the mixing plate cooperates with the drainage holes on its surface to tumble and mix the culture medium liquid and water mixture in the box body. However, when used, this design fails to effectively solve the problem of the ideal immersion depth of the potato root system in the nutrient solution. The root system may be completely immersed for a long time due to the high liquid level, resulting in lack of oxygen and rot; or because the liquid level is too low, only part of the root tip contacts the nutrient solution, resulting in serious uneven nutrient absorption of the entire root system, affecting the balanced growth of the seedlings. The stirring blades installed in the box are very likely to physically collide or entangle with the fragile roots of the potato seedlings during continuous operation, causing mechanical damage or even breakage of the roots. This damage not only directly hinders the root absorption function, but also creates an entry point for pathogens to invade, significantly increasing the risk of seedling disease and death.

[0004] Based on this, an adjustable potato breeding seedbed is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
