Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a biological compound fertilizer. Background technique [0002] China has a vast land and abundant resources, is a big agricultural country, and is also a big fertilizer user. According to the statistics of my country's Ministry of Agriculture, the annual use of chemical fertilizers in my country accounts for 35% of the world's total. In the prior art, the development from farmyard manure to chemical fertilizers, the application of chemical fertilizers has led to a rapid development of agricultural production, but chemical fertilizers pollute the environment, compact the soil, destroy the soil structure, and gradually reduce or even exterminate many beneficial microorganisms in the soil, thus making the soil fertility Defects such as decline in crop quality and poor crop quality pose a threat to the sustainable development of agriculture in our country and the living environment of hu...
