The invention relates to a long-acting synergistic multifunctional stable green
fertilizer, in particular to a green
fertilizer which is prepared by using
polyaspartic acid, compound
selenium nucleic acid, compound
sodium nitrophenolate, medium trace elements and an
organic matter as raw materials, and is subjected to mixing, co-crystallizing and granulating, belonging to the field of agricultural
fertilizer. The long-acting synergistic multifunctional stable green fertilizer is prepared by proportioning the
polyaspartic acid, the compound
selenium nucleic acid, the compound
sodium nitrophenolate, the medium trace elements and the
organic matter in percentage terms, mixing, stirring, granulating,
drying, cooling, sieving, metering and packaging. The long-acting synergistic multifunctional stable green fertilizer has the advantages of
long acting,
synergy, quick acting, green, high yield and high quality. The medium trace elements in the fertilizer provided by the invention are used for adjusting the balance relation of elements in soils so that the pests and diseases are reduced effectively and the use amount of the pesticides and fungicides is reduced greatly. The
organic matter in the fertilizer has the
efficacy of activating the soil, improving the water and fertilizer retention of soils, promoting the growth of crops, enhancing the
disease resistance of the crops and improving the quality of the crops and is green and environment-friendly.
