二、营养液的组成与配制生长在水培环境中的植物,所需的营养元素是从人工施入水中的营养元素化合物吸取的。含有从种类、形态、比例、数量、浓度、酸碱反应等都适合植物正常生长发育需要的营养元素化合物的水溶液,称为营养液或培养液。 1.营养液的组成。从种类上说,营养液必须含有植物吸取的全部营养元素,这就是氢、氧、氮、磷、钾、钙、镁、硫、铁、硼、锰、铜、锌、钼、氯。从形态上说,这些必需的营养元素,主要是以能溶于水的无机盐形态供应。氢和氧就是
Second, the composition and preparation of nutrient solution Growing hydrophytes in the environment of plants, the nutrients required from the artificial application of water into the nutrient elements of the compound. Contains from the species, morphology, proportion, quantity, concentration, acid-base reaction and so on are suitable for the normal growth and development of plant nutrients required for the aqueous solution, known as the nutrient solution or culture solution. 1. Nutritional fluid composition. By type, the nutrient solution must contain all the nutrients that the plant takes in, which is hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, iron, boron, manganese, copper, zinc, molybdenum, and chlorine. Morphologically, these essential nutrients are supplied mainly in the form of inorganic salts that dissolve in water. Hydrogen and oxygen are
