Description

Technical Field

[0001] The present invention relates to the technical field of agricultural seedling cultivation, and more specifically, to a sweet potato seedling hydroponic rapid propagation device and a use method thereof. Background Art

[0002] Sweet potato is a raw material crop rich in processed products, especially suitable for industrial development, and provides sufficient raw materials for the development of starch, food, fermentation and other processing industries. The moderate development of the sweet potato industry is conducive to ensuring national food security and improving people's health. Every 100g of fresh potato contains 29.5g of carbohydrates, 0.2g of fat, 20mg of phosphorus, 18mg of calcium and 0.4g of iron. In addition, sweet potatoes are rich in dietary fiber, vitamin C, B vitamins and antioxidant ingredients, which help promote intestinal peristalsis, prevent constipation and improve digestive function. At the same time, the rich antioxidants in sweet potatoes, such as β-carotene and polyphenol compounds, help to remove free radicals, delay aging and reduce the risk of chronic diseases. Its low fat and high nutritional characteristics also make it an ideal food for cardiovascular health, helping to control cholesterol levels and protect blood vessel health. Eating sweet potatoes in moderation can not only supplement the various nutrients needed by the human body, but also enhance immune function and improve disease resistance, which is of great significance to modern people's pursuit of a healthy lifestyle.

[0003] In the breeding of sweet potato seedlings, the cultivation of excellent seedlings has a vital impact on the final yield and quality. Therefore, the efficient cultivation of healthy seedlings is of great significance. As a modern seedling technology, hydroponic seedling cultivation has significant advantages. Through hydroponic seedling cultivation, precise control of nutrient supply can be achieved, avoiding the risk of soil-borne diseases. At the same time, the seedling growth environment is clean and tidy, reducing the occurrence of diseases and insect pests. In addition, hydroponic seedlings do not require large areas of arable land, and have a higher utilization rate of resources, which is more in line with the requirements of modern agricultural conservation and efficiency.

[0004] However, despite the many advantages of hydroponic seedling cultivation, it also faces certain problems and challenges in practical applications. First, during the hydroponic process, it is necessary to monitor the changes in environmental parameters such as temperature and humidity in real time, which makes management difficult. Secondly, debris and decomposition products are easily left on the water surface in the hydroponic system. If these impurities are not cleaned up in time, they will not only hinder the exchange of oxygen, but also breed microorganisms, causing water quality deterioration, and thus affecting the healthy growth of seedlings. In addition, water needs to be frequently replenished during the hydroponic process, but under the existing technical conditions, decomposition products and waste in the water body are difficult to completely remove by simply replacing the water, and long-term accumulation may have an adverse effect on plant growth. These problems indicate that in order to further promote and optimize hydroponic seedling technology, improvements need to be made in system design, management methods and water purification technology to fully tap its potential and promote the development of the sweet potato industry.
