Hydroponics (Hydroponics) is a novel soilless culture mode of plants, also called nutrient solution culture, and is characterized in that root systems of the plants are directly soaked in nutrient solution, and the nutrient solution can replace soil and provide growth factors such as water, nutrients, oxygen and the like for the plants, so that the plants can normally grow. The growth speed of the crops produced by water culture is high, the growth condition is not influenced by factors such as regions, seasons and the like in the external environment, so that the economic benefit of the crops cultured by water is quite high, the industrial production and the automatic production of the crops are convenient to realize by water culture, and the water culture is vigorously applied and popularized. The nutrient solution proportion is crucial to the water culture production and is a source of energy and energy required by the growth and development of crops. If the nutrient solution is excessive and causes root rot due to burning, the eutrophic circulating water system breeds algae to grow, and the dissolved oxygen in the water drops suddenly. If the nutrient solution is insufficient, the growth, development and flowering of plants are influenced; if nutrients are not available for a long time, it can also lead to death. Different proportions of various nutrient elements (nitrogen, phosphorus, potassium and trace elements) in the nutrient solution can also influence the growth of crops. Therefore, the selection and the configuration of the nutrient solution are key technologies of aquatic cultivation, and the quality and the yield of the water culture production are directly determined.
