Fertilizer is an important factor in determining crop yield and quality. Fertilizers are generally divided into organic fertilizers (farm fertilizers), inorganic fertilizers (fertilizers) and microbial fertilizers, ie, fungus fertilizers. Fertilizer is a fertilizer made by artificially cultivating certain beneficial microorganisms. It is a product of microbial life activities to increase soil fertility, stimulate plant growth, or inhibit the activities of harmful microorganisms, increase crop resistance to disease and stress resistance, and promote crop absorption of nutrients. It acts as a "factory" between other fertilizers and crops. It is a transformation and synergistic effect on other fertilizers, but it is not sufficient to replace other fertilizers. Organic fertilizer, also known as farmyard fertilizer. Such as human excrement, livestock and poultry excrement, etc., contain various nutrients and rich organic substances required by the crop, which is a complete fertilizer. However, most of their nutrients are in the form of organic compounds and must be decomposed by microbial fermentation before they can be used by crops. In general, decomposition is slow and the fertilizer is long and it is a chronic fertilizer. It can improve soil structure, provide energy and nutrients for microbial life activities, and promote the activity of soil microorganisms, which can effectively regulate water, fertilizer, gas, and heat in the soil, thereby improving soil fertility. It can be seen that the bacterial fertilizer and the organic fertilizer have complementary effects, and if the two organically and reasonably combine and develop into a biological organic fertilizer, its efficacy will be more significant. Shijiazhuang Oasis Bio-organic Fertilizer Plant uses ZJS multi-dimensional complex bacteria to treat bio-organic fertilizer made from fresh chicken manure, which realizes the organic combination of bacterial fertilizer and organic fertilizer. It is a high-tech modern bio-engineering technology. Fermentation process is unique, the method is simple, easy to promote, low cost, no pollution, sustained release, high efficiency, pollution-free, significant effect. Compared with fresh chicken droppings: 1. It is conducive to ecological and environmental protection. Firstly, the foul odor of fresh chicken manure seriously pollutes the surrounding environment, and secondly, the fresh chicken manure contains a large number of harmful eggs and harmful bacteria, such as salmonella typhi, pyogenic bacteria, E. coli, fly lice, roundworm eggs, hookworm eggs, etc. After the application, the source of infection was expanded and chicken diseases occurred frequently. At the same time, harmful bacteria and harmful eggs directly threatened the growth of crops. With this bio-organic fertilizer, deodorization and fermentation of fresh chicken manure are first performed. The fermentation temperature of 60-70 °C can effectively kill a large number of pathogens and harmful eggs in chicken manure, reduce the spread of germs and chicken disease, reduce the incidence of crop diseases and insect pests, and help protect the ecological environment. 2, full nutrition, high efficiency. The bio-organic fertilizer is based on chicken manure as a carrier of bacteria, not only nutritious, and contains a large number of beneficial bacteria. After application, not only chicken manure can be rapidly decomposed into nutrients that can be directly absorbed by crops, but also decomposition of decomposition of farmland straw and other organic matter can be accelerated, and dead potassium in the soil can be transformed into crops that can be absorbed and utilized by dead plants. The soluble live phosphorus potassium, compared to the use of fresh chicken manure, the fertilizer effect is fast, high efficiency. The amount of chemical fertilizers can be greatly reduced, which is of great significance for improving the quality and yield of fruits and vegetables. 3, easy to use. The fertilizer is dark brown granular, and it is very convenient for transportation, storage and use. Fresh chicken manure is mostly viscous, dirty, odorous and sticky. It is quite inconvenient to use.
