Problems solved by technology

[0002] With the frequent and single use of chemical fertilizers, the soil environment is adversely affected. In the absence of sufficient organic matter, the soil aggregate structure is difficult to form, and the adhesion between soil particles is weakened. Water retention capacity, in general large-scale chicken farms, due to the considerable number of chickens, the treatment of cow dung has always been a problem that needs to be solved. Because of a relatively high-quality organic fertilizer, applying cow dung as organic fertilizer to plants will have great Good effect, but the effect of cow manure fertilizer is fast, the loss of nutrients is serious, and the nutrition is relatively simple
