Description

Technical Field

[0001] This utility model relates to the technical field of seedling raising devices, specifically a seedling raising device that uses circulating water heating to shorten the seedling raising time. Background Technology

[0002] Temperature is a key factor affecting seedling growth and development in agricultural seedling cultivation, persisting throughout the entire seedling growth cycle and playing a decisive role in its physiological activities, growth rate, and final quality. From the moment seeds germinate, temperature profoundly influences the germination process. Different crop seeds have specific temperature requirements for germination. For example, the suitable germination temperature for solanaceous crops (tomatoes, peppers, etc.) is mostly between 25-30℃. Within this range, seed enzyme activity is high, metabolism is vigorous, and the processes of water absorption, swelling, and breaking through the seed coat are more efficient. If the temperature is too low, seed physiological activities are inhibited, germination is delayed or even dormant, and the germination rate is sharply reduced; if the temperature is too high, it may damage the seed protein structure, causing it to become inactive and unable to germinate. However, current seedling cultivation devices often lack efficient and uniform heating systems, and temperature control is not precise enough, resulting in long seedling cultivation times. Therefore, we propose a seedling cultivation device that uses circulating water heating to shorten the seedling cultivation time. Utility Model Content
