Description

Technical Field

[0001] This utility model relates to the field of plant domestication technology, and more specifically, to a plant seedling low-temperature domestication device. Background Technology

[0002] Plant domestication refers to the long-term process by which humans, through selection and cultivation, modify wild plants to meet human needs. This includes altering plant morphology, yield, nutritional composition, and environmental adaptability. Domestication is fundamental to agricultural development, enabling humans to obtain food sources more stably. However, the introduction and domestication of plants also faces challenges, such as the vulnerability of single varieties and declining environmental adaptability. These are significant issues in current agricultural development. Therefore, in current applications, technicians typically select introduction methods suitable for different types of plants and environmental conditions.

[0003] For low-temperature environments such as high altitudes, high latitudes, and severe winters, it is necessary to provide a low-temperature acclimatization environment during the introduction and cultivation cycle. For example, patent CN211353331U provides an intelligent low-temperature acclimatization device for plant seedlings, including an acclimatization chamber. A cool air fan is located on the right side of the acclimatization chamber, connected to a main ventilation pipe. The main ventilation pipe is located inside the acclimatization chamber and has branch pipes. A cultivation box is fixedly connected to the inner wall of the acclimatization chamber. The branch pipes pass through one side of the cultivation box and are located inside the cultivation box. An observation window is opened on the front of the cultivation box. A mounting plate is fixedly connected to the cultivation box, and a hydraulic cylinder is fixedly connected to the mounting plate. A baffle is fixedly connected to the piston end of the hydraulic cylinder. The cool air fan lowers the temperature inside the acclimatization chamber, and the main ventilation pipe and branch pipes allow cold air to be introduced into the cultivation boxes separately, enabling the classification and management of different plants and facilitating plant acclimatization.

[0004] However, existing plant seedling acclimatization devices, such as those mentioned above, have the following problems in practical applications: because the cold air blower in the device blows air towards the plant seedlings, and the seedlings themselves are relatively fragile, the plant seedlings near the cold air outlet are very prone to overheating and frost damage. Utility Model Content

[0005] The purpose of this invention is to solve the problem of concentrated cold air outlets in existing low-temperature plant acclimatization devices, which makes some seedlings highly susceptible to frost damage. This application provides a low-temperature acclimatization device for plant seedlings, in which the cold air outlet is oriented away from the seedlings, and a buffer component is sandwiched between the outlet and the seedlings, so that the cold air can slowly and evenly act on each seedling in the acclimatization box during its descent.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a plant seedling low-temperature acclimatization device, including an acclimatization box and a cold air box disposed on the top of the acclimatization box, and the cold air box is connected to the acclimatization box; the inner cavity of the cold air box is equipped with a cold air fan and a buffer assembly, the air outlet of the cold air fan is arranged in a horizontal direction or away from the acclimatization box, and the buffer assembly includes multiple buffer plates, and the multiple buffer plates are detachably connected to different side walls of the acclimatization box.

The horizontal strips and the vertical strips are arranged at different heights in the vertical direction.

[0009] Preferably, in the plurality of horizontal strips, the ends of two adjacent horizontal strips are respectively mounted on opposite inner walls of the air conditioning unit.
