The study looked at how growing tobacco seedlings in shallow water trays can benefit their growth. Compared to traditional floating seedlings, the shallow water method resulted in higher temperatures, better seedling emergence rates, and improved growth characteristics like age, weight, and root system. These tobacco seedlings showed faster growth after planting, leading to higher leaf yield and quality. Additionally, using less water in this method can help reduce costs and water use pressure in dry regions. Overall, the shallow water tray method combines the advantages of floating and tray seedling techniques, making it a promising option for tobacco seedling growth.
