What is the time when the maximum number of inorganic salts is needed
Plant inorganic salts are the most nitrogen, phosphorus and potassium containing inorganic salts, if any lack of plant will affect the normal growth.
The content of phosphorus in plants is lower than that of nitrogen and potassium, and is generally higher in seeds. Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis in plants , Respiration, energy storage and delivery, cell division, cell enlargement and other processes.
Potassium is ion-soluble in plant juice, and its main function is related to the metabolism of plants.
Nitrogen is the basis of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll, enzymes, vitamins, alkaloids and some hormones, etc. Nitrogen is also the basis of genetic material. In all organisms, the protein is most important, it is Often at the center of metabolic activity, which is the primary factor limiting plant growth and yield, and has a significant effect on improving product quality.
Seedling stage requires the largest amount of inorganic salts, because the seedling period is to lay the foundation for the growth period, in the strong growth period is mainly composed of synthetic organic matter.
