Today organic fertilizer has replaced chemical fertilizers, due to shortage of places both have now to develop eco-organic fertilizer, organic eco-fertilizer into the soil, to go through microbial decomposition into inorganic forms, can be absorbed by plants. Changzhou ecological advantages of bio-organic fertilizer plant: 1. bio-organic fertilizer compared with chemical fertilizers: (1) complete bio-organic fertilizer nutrients; fertilizer nutrients only one or several. (2) bio-organic fertilizer can improve soil; frequent use of fertilizers can cause soil compaction. (3) bio-organic fertilizer can improve product quality; fertilizer overuse leads to poor product quality. (4) biological organic fertilizer to improve crop rhizosphere microorganisms, improve resistance to diseases and pests of plants; fertilizer microbial population is single crop, pest and disease prone. (5) promote the use of bio-organic fertilizer fertilizer can improve the utilization of fertilizers; fertilizer alone could easily lead to the loss of fixed and nutrients. 2. bio-organic fertilizer and organic fertilizer compared to refined: refined organic fertilizer is manure after drying, after crushing packaged goods sold organic fertilizer. (1) bio-organic fertilizer full maturity, do not burn the roots, not bad seedlings; refined organic fertilizer without maturity, directly after use composting in the soil will cause burn seedlings phenomenon. (2) high temperature composting of bio-organic fertilizer, killing most of the pathogen and eggs, reduce pests and diseases; refined organic fertilizer without maturity, at maturity will lead to soil pests in the soil. (3) bio-organic fertilizer added to bacteria, due to mass effect flora and reduce the occurrence of disease; refined organic fertilizer due to high temperature drying, kills all microorganisms inside. (4) bio-organic fertilizer nutrient content; refined organic fertilizer because of high temperature, resulting in the loss of nutrients. (5) bio-organic fertilizer by the odor, the smell of light, almost odorless; refined organic fertilizer without deodorant, damp stench appears. 3. bio-organic fertilizer and manure (organic fertilizer traditional) differences: (1) bio-organic fertilizer full maturity, egg mortality rate of more than 95%; manure pile simple egg mortality is low. (2) bio-organic fertilizer odorless; stench of manure. (3) facilitate the bio-organic fertilizer evenly; manure application inconvenient, fertilizer uneven. 4, the difference between bio-organic fertilizer and bio-fertilizer: (1) bio-organic fertilizer cheap, about 1,000 yuan per ton; bio-fertilizer is expensive, the yuan per ton. (2) bio-organic fertilizer containing functional bacteria and organic matter, soil can promote the release of fixed soil nutrients; bio-fertilizer containing only bacteria function to promote the use of fertilizers by fixing soil bacteria function. (3) bio-organic fertilizer organic matter itself is functional bacteria living environment, soil fertilized likely to survive; and the function of biological fertilizer bacteria may not be suitable for some of the soil environment.
