Nitrogen is one of the most needed elements for ordinary crops, and nitrogen fertilizer is the most widely used chemical fertilizer in China. Nitrogen fertilizer can obviously promote crop growth, quickly improve leaf color, get immediate results from fertilization, and obviously increase crop yield, which has the function of low input and high output, so it is well received by users. Nitrogen fertilizer is the main fertilizer to promote the growth of roots, stems and leaves of flowers. Those inedible oils such as beans, peanuts, melon seeds, hemp seeds and small hemp seeds are all good nitrogen fertilizer raw materials. If these things are fermented and decomposed, diluted with water and poured into the soil, flowers will thrive.

◆ Phosphate fertilizer

Phosphate fertilizer, like nitrogen fertilizer, is an essential fertilizer for agriculture in China. At present, the most commonly used phosphate fertilizer is superphosphate. Phosphate fertilizer can improve the drought resistance, cold resistance and salt resistance of crops, and has the functions of early maturity, yield increase and quality improvement. However, due to the slow dissolution of phosphate fertilizer in soil, the utilization rate of phosphate fertilizer by crops is much lower than that of nitrogen fertilizer and potassium fertilizer. Phosphate fertilizers commonly used in China include superphosphate, superphosphate, calcium magnesium phosphate and ammonium phosphate. Ammonium phosphate is mainly used to produce various compound fertilizers because of its good particle shape, while other phosphate fertilizers are usually used for direct application. The raw materials of phosphate fertilizer are fish bones, bones, eggshells, freshwater fish scales, cut hair, nails and so on. Mix these impurities evenly in the flower soil, or after fermentation, dilute them with water and pour them into the pot soil, which will make the flowers bright and colorful and the fruits full.

◆ Potash fertilizer

After nearly 20 years of application practice, the Canadian-produced red potash fertilizer has been widely accepted and used since it entered the China market. For example, in Guangdong banana producing areas, banana growers clearly know that potassium fertilizer can obviously increase the yield, especially the yield per ear of bananas. Larger ears usually cost more, so growers get higher planting income. Applying potassium fertilizer can increase the ability of flowers to resist lodging and control diseases and pests. Taomi water, leftover tea and bottle washing water are good potash fertilizers, and also contain certain nitrogen and phosphorus components.
