肥料是花卉养料的来源,施肥的合理与否,直接影响到花卉的生长和发育,关系到花卉的产量和质量。植物生长发育需要的元素比较多,主要成分为氮、磷、钾“三要素”,其次是钙、铁、硫、镁、硼、锰、铜、锌、钴、碳、氢、氧,其中的碳、氢、氧,可以从水和空气中得到,其余元素则需要从土壤中吸收。氮、磷、钾,单纯靠培养土供给是不够的,因此,需要通过施肥来补充。
Fertilizer is the source of flower nourishment, fertilization is reasonable or not, directly affect the flower growth and development, related to the yield and quality of flowers. Plant growth and development needs more elements, the main components of nitrogen, phosphorus and potassium “three elements”, followed by calcium, iron, sulfur, magnesium, boron, manganese, copper, zinc, cobalt, carbon, hydrogen, oxygen, which Carbon, hydrogen, oxygen, can be obtained from water and air, the rest of the elements need to be absorbed from the soil. Nitrogen, phosphorus and potassium are not enough to supply pure culture soil, therefore, they need to be supplemented by fertilization.
