It is a kind of complete fertilizer, also known as farmyard fertilizer in China. The natural organic matter is decomposed or fermented by microorganisms. For example, green manure, human manure, manure, compost, retting, biogas fertilizer and waste fertilizer.
It not only contains nitrogen, phosphorus and three important elements, but also microelements and growth stimulants, which have the most demand for flower growth. It also has an important role in promoting its growth. The application of organic fertilizer can improve the soil structure and increase the soil water holding capacity. Therefore, more organic fertilizer should be applied.
It is mineral fertilizer, also known as chemical fertilizer, which is made by chemical synthesis or natural ore processing. Fertilizer mainly in the form of inorganic salt.
The nitrogen, phosphorus, potassium and other nutrients are all in the form of inorganic compounds, which are used as foliar spray fertilizer.
In the growth period, the fertilizer mainly composed of nitrogen should be applied 1-2 times.
For ornamental flowers, nitrogen fertilizer should be applied once every ten days when the branches and leaves grow. When the flower buds differentiate and form to the growth stage before flowering, nitrogen and phosphorus fertilizer should be applied once or twice.
Organic fertilizer, bone meal, superphosphate and so on are directly mixed into the culture soil. This method is called base fertilizer. The amount of organic fertilizer should not exceed 10% of the culture soil, and the amount of inorganic fertilizer should not exceed 1%.
In the growth and development period of flowers, the fertilizer applied according to different needs is called top dressing. Its concentration is very low, such as urea, diamine, etc. need to add water 100-1000 times to dissolve. Add more than 10 times of water to dilute the clear liquid of organic fertilizer, and then use it again.
It's also called root topdressing. Spray is used to spray liquid fertilizer on the leaf surface, and the fertilizer dissolved in water directly enters the plant through the leaf stomata and stratum corneum, and is called foliar top dressing.
