Technical Field
The invention relates to the field of fertilizers, in particular to a fertilizer synergist and an organic fertilizer using the fertilizer synergist.
Background
The fertilizer is an important agricultural production data, and plays a significant role in promoting grain production and agricultural development. However, due to the deficiency of advanced technology, the traditional fertilizer in China is transformed too fast in soil and is easy to be lost into air and water body through volatilization, runoff, permeation and other modes, so that not only is the utilization rate low, but also a series of environmental problems such as environmental pollution, ecological balance damage and the like are brought, and the agricultural ecological environment safety in China is seriously threatened.
The organic fertilizer has the advantages of improving soil, improving crop quality and the like, and becomes the development direction of the current fertilizer. However, the traditional organic fertilizer has the limiting factors of slow fertilizer efficiency, large application amount (>1 ton/mu), high cost (>500 yuan/mu) and the like, and is difficult to popularize in a large area. Therefore, the existing organic fertilizer is urgently upgraded and modified, and the application-reducing and efficiency-improving technology is developed to enhance the fertilizer efficiency, reduce the using amount, save the cost, promote the agricultural ecological and organic aspects and ensure the national food and environment safety.
