Background technique

Liquid fertilizer is a new type of fertilizer in China in recent years. With the continuous development of agricultural technology, liquid fertilizer is not an ordinary foliar fertilizer. Liquid fertilizer is a liquefaction of solid fertilizer, which is in line with the national development trend. Liquid fertilizer is not easy to damage roots and seedlings. Dissolving and dilution does not cool down, and it is easy to distribute evenly in the soil after application, unlike solid fertilizers that form concentrated fertilization with high local salinity, dilution and cooling, and damage to roots and seedlings; liquid fertilizers can reduce water infiltration and evaporation, and improve water utilization. Liquid fertilizer realizes balanced fertilization and centralized fertilization, reduces fertilizer volatilization and loss, and losses caused by excess nutrients, and has the advantages of simple fertilization, timely fertilizer supply, easy absorption by crops, and improved fertilizer utilization. Liquid fertilizer can improve the ecological environment, enhance the activity of microorganisms, promote the absorption of nutrients by crops, and increase the yield of crops. Therefore, liquid fertilizer has gradually developed, and the corresponding agricultural machinery has also been continuously upgraded and replaced, and various liquid fertilizer fertilization machinery should be born.
