In the process of plant growth, there is no need for nutrients. There are large and micronutrient elements. At the same time, some plants also need some regulators to promote growth. What things contain nitrogen, phosphorus and potassium?
Effects of phosphorus, potassium and nitrogen on plants
1. Nitrogen fertilizer: Nitrogen in the material is the function of nitrogen element, which can promote the lush growth of plant stems and leaves, and the leaves are dark green. The effect is obvious in the early stage of plant growth, which is why many plants apply nitrogen fertilizer heavily in the early stage of flower, and nitrogen element accounts for a large proportion in the whole growth period.
2. The role of phosphorus fertilizer: The role of phosphorus in the process of plant growth is mainly to promote plant branching, more flowering and fruiting, and improve the fruiting rate. That is, in the middle period of plant growth, phosphorus is relatively needed, and the main use time is before flower.
3. Effect of potassium fertilizer: Among the three elements, nitrogen fertilizer is used in the first place, followed by potassium fertilizer, which mostly plays a role in the later stage of plant growth, such as the fruiting stage. Topdressing potassium fertilizer can promote fruit expansion, coloring and ripening, and can help some stem plants resist lodging, drought and disease resistance.
Through the understanding of the three elements needed in the process of plant growth, can be a good combination of their own plant growth to appropriate supplement, can be configured, you can also go to the flower market to buy some different content of nutrient fertilizer for topdressing.
