Description

technical field

[0001] The invention relates to the technical field of plant factory vegetables, in particular to a nutrient solution suitable for growing vegetable seedlings in a plant factory and a method for cultivating seedlings. Background technique

[0002] At present, almost all plant factories adopt the nutrient solution cultivation mode. The nutrient solution is the material basis for plant growth under the condition of nutrient solution cultivation. The composition and concentration of the nutrient solution directly affect the speed of crop growth and development, and are related to crop yield, quality and Economic benefits, by adjusting the nutrient solution, the plants can grow normally, and finally high-yield and high-quality vegetables can be obtained. However, the nutrient solutions on the market are not completely suitable for sesame leaves, Jingshui vegetables, collard greens and mustard vegetables, especially in the stage of hydroculture seedlings, which ha...
