Classification of fertilizers in flower growth
The present invention provides a multifunctional pull faucet, comprising: a faucet body, a drawing part is provided at the water outlet port thereof, and the drawing part is connected to a main channel, wherein at least three are provided in the faucet body A branch channel, and the three branch channels are all connected to the main channel. A multifunctional pull faucet provided by the present invention, wherein the hot water channel, the cold water channel and the water purification channel (pure water channel) are all connected to the main channel , And the main channel is connected with the drawing part on the main body of the faucet, so that the drawing part can obtain the water quality (hot water, cold water, purified water or pure water) required by different users, thereby improving the user experience, and , By integrating the hot water channel, cold water channel and pure water channel (pure water channel) into the main channel, the internal structure of the faucet is simplified, and the production cost of the faucet is reduced..

According to the nature of fertilizer can be divided into:
Organic fertilizer: also known as farmyard fertilizer, natural fertilizer. Such as human excrement, livestock hooves, fish bones, circle fertilizer, river mud, green manure, decaying animal and plant residues. Generally, it is rich in nutrients, slow in fertilizer efficiency and long in fertilizer efficiency, so it is also called delayed fertilizer.
Inorganic fertilizer: Also known as chemical fertilizer, the nutrient content is high but the composition is relatively simple. Therefore, the combination with organic fertilizer is more effective. It is characterized by fast fertilizer efficiency, also known as quick-acting fertilizers, such as ammonia sulfate and urea.
According to the method of fertilization, it can be further divided into:
Base fertilizer: refers to the fertilizer applied to the soil before planting in the open field or before the potted pot. The base fertilizer generally uses solid granular fertilizers such as manure, manure, hoof, and superphosphate.
Top dressing: Fertilizer applied during flower growth and development. In order to supplement the deficiency of nutrients in the soil or the cultivation substrate, such as root dressing, liquid fertilizer is often used.
According to the nutrients contained in the fertilizer, there are mainly:
Nitrogen fertilizer: such as human excrement, manure, cake fertilizer, ammonium sulfate, urea and so on. Mainly promote the growth of flowers and trees.
Phosphate fertilizer: such as bone meal, surimi, superphosphate. The main function is to promote the flowering and fruiting of the flower, and to make it full of shape, bright colors and rich fruit.
Potassium fertilizer: such as grass ash, potassium nitrate. The main function is to promote the thick and solid flower stems, the developed root system and enhance the cold resistance.
At present, a slow-release fertilizer is vigorously developed in the United States, Japan, and Western Europe. Their solubility in water is small, so nutrients can be continuously released for flower absorption, and the fertilizer efficiency can be as long as 3.5 years, such as urea formaldehyde and isobutylidene diurea.
