The leaf vegetables are vegetables taking fat and tender leaves and petioles of plants as edible parts, and account for 1/3-2/3 of vegetable biomass. Common leafy vegetables include rape, leek, lettuce, celery, spinach, amaranth, endive, cabbage, garland chrysanthemum, agaric, and the like.
Soilless culture is a modern seedling culture technology which takes grass carbon or light materials such as forest leaf mold, expanded vermiculite and the like as seedling culture substrates to fix plants, enables plant roots to directly contact nutrient solution and adopts mechanical precision seeding to grow seedlings once. The nutrient solution artificially prepared in the soilless culture is used for providing mineral nutrition for plants, and the culture technology is a culture technology which does not use natural soil but adopts the nutrient solution containing essential elements for plant growth and development to provide nutrition so that the plants normally complete the whole life cycle. The key to the success of water culture is the preparation and use of nutrient solution.
