Description

technical field [0001] The invention relates to a nutrient solution technology specially used for hydroponics of glass lettuce, which belongs to the field of soilless cultivation. Background technique [0002] Hydroponics is a new type of soilless plant cultivation, also known as nutrient liquid culture. Its core is to fix the plant rhizomes in the planting basket and let the roots naturally hang into the plant nutrient solution. This nutrient solution can replace the natural soil to Plants provide growth factors such as water, nutrients, oxygen, and temperature, so that plants can grow normally and complete their entire life cycle. This kind of plant cultivation technology that reflects advanced productivity has the advantages of intensive, large-scale and precise production, and the hydroponic plants cultivated by this soilless cultivation technology are more famous for their cleanliness, elegant style, strong ornamental value, The advantages of environmental protection a...
