Description

Technical Field

[0001] This utility model relates to the field of nutrient solution production technology, specifically to a nutrient solution mixing device for increasing the selenium content of agricultural products. Background Technology

[0002] Nutrient solutions are prepared solutions that provide nutrients for soilless cultivation crops. They are mainly composed of elements such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, as well as trace elements, with a total concentration typically not exceeding 0.4%. Differences in formulation mainly lie in the adjustment of the nitrogen-potassium ratio. Chemical fertilizers must be used in the preparation process. Calcium must be treated separately during preparation to prevent precipitation. The pH value should be controlled within the range of 5.5-8.5. The water hardness should be below 15°, and sodium and chloride ion levels should be kept within acceptable limits. Metal containers are prohibited, and inorganic salts must be dissolved in the correct order.

[0003] To improve the nutritional value of agricultural products, selenium compounds are sometimes added to the nutrient solution. The nutrient solution needs to be stirred during preparation. Existing stirring devices mainly consist of a stirring shaft and a stirring rod, which have low stirring and mixing efficiency and poor uniformity of nutrient solution mixing, and need to be improved.
