　　Organic fertilizer,commonly known as farmyard fertilizer,refers to a large amount of biomass,animal and plant residues,excreta,biological waste and other substances of slow-release fertilizer.Organic fertilizer contains not only large amounts of elements and trace elements required by plants,but also organic fertilizer is rich in organic nutrients.The main role of organic fertilizer in agricultural production is shown in the following aspects:

　　1：Soil improvement and fertility improvement After applying organic fertilizer into the soil,organic matter can effectively improve the soil physical and chemical conditions and biological characteristics,ripen the soil,enhance the ability of soil to maintain and supply fertilizer and buffer,and create good soil conditions for crop growth.

　　2：Increase production and improve quality.Organic fertilizer is rich in organic matter and various nutrients,providing nutrients for agricultural crops.After decomposition of organic fertilizer,it provides energy and nutrients for soil microbial activities,promotes microbial activities,accelerates decomposition of organic matter,and produces active substances that can promote crop growth and improve agricultural products

　　3：Improve fertilizer utilization rate.Organic fertilizer contains a variety of nutrients,but its relative content is low,and its release is slow,while chemical fertilizer has high nutrient content per unit,low composition,and fast release.The two can be reasonably applied and complement each other to decompose organic matter.The organic acid produced can also promote the dissolution of mineral nutrients in soil and fertilizer.Chemical fertilizer and organic fertilizer promote each other,which is beneficial to crop absorption and improve fertilizer utilization rate.
