Whether or not the flower grows long is closely related to the proper application of fertilization. Fertilizer is one of the material bases for the growth of a class of grass flower that provides one or more essential nutrients for grass flower, or can improve the soil properties and increase the level of soil fertility.
Fertilizers are usually divided into two categories: organic fertilizers and inorganic fertilizers. Fertilizer is the source of grass nutrients. Rationality of fertilization directly affects the growth and development of grass flowers, and relates to the yield and quality of flowers. Grass plants need more elements for growth and development. The main components are the "three elements" of nitrogen, phosphorus and potassium, followed by calcium, iron, sulfur, magnesium, boron, manganese, copper, zinc, cobalt, carbon, hydrogen and oxygen. The carbon, hydrogen and oxygen can be obtained from water and air, and the remaining elements need to be absorbed from the soil. Nitrogen, phosphorus, and potassium are not sufficient because of the supply of culture soil. Therefore, it is necessary to supplement them with fertilization.
Fertilization is divided into two categories: base fertilizer and top dressing. Basal fertilizer refers to the fertilizer applied to the soil before planting the flowers. The grass is planted in the open field. The base fertilizer is mixed in the soil first, and then the soil is replanted; the potted flowers in the indoor pot can be used in the basin. The bottom layer of soil is put into basal fertilizer, such as bean cake and fish bone powder.
Topdressing refers to fertilizers that are applied in the growing season of grass seedlings. Open field grass flowers can be dried around the flower seedlings, and then watered, can also be directly shed manure. Potted grass flowers can be sprinkled with dried fertilizer on the surface of potted soil, then loosened and watered.
