[0002] Agricultural technology extension refers to the activities of popularizing agricultural technology and applying it to the entire process of agricultural production, including pre-production, production, and post-production, through means such as experimentation, demonstration, training, guidance, and consulting services. Its purpose is to promote scientific and technological achievements and practical technologies applied to planting, forestry, animal husbandry, and fishery to the vast number of farmers, thereby improving agricultural production efficiency and benefits.

[0003] For example, Chinese utility model patent CN219812700U discloses a three-dimensional multi-layer seedling rack based on agricultural technology extension. This rack includes several cultivation boxes, each with four cultivation chambers at its upper end. A support rod is fixedly mounted on each cultivation box, and several lighting components are fixedly mounted on the outer surface of the support rod. Four first connecting blocks are fixedly connected to the outer surface of the lowest cultivation box. A fixing frame is fixedly connected to the end of each of the four first connecting blocks away from the cultivation box. A sliding groove is formed at the end of each of the four fixing frames near the cultivation box, and a water spray component is slidably installed within each of the four sliding grooves. This three-dimensional multi-layer seedling rack based on agricultural technology extension, by incorporating the water spray components, reduces the labor burden on workers and facilitates the cultivation of higher-level crops; by incorporating the lighting components, it improves crop cultivation efficiency and saves manpower and resources.

[0004] In agricultural technology extension activities, multi-layer seedling racks are needed for seedling cultivation. However, in the use of existing multi-layer seedling racks, the cultivation boxes are fixedly installed on the support rods, resulting in a fixed distance between two adjacent cultivation boxes. Since the height of the seedlings gradually increases, the multi-layer seedling rack will hinder the growth of the seedlings when they reach a certain height, thus affecting the effectiveness of the multi-layer seedling rack.
