plant biological
organic fertilizer. The
plant biological
organic fertilizer comprises, by weight, the following components: 10 to 20 parts of bean pulp, 7.5 to 15 parts of
bone meal, 40 to 60 of turfy soil, 30 to 50 parts of
fungus planting abandoned soil and 0.2 to 0.4 part of biological
bacteria (such as fast brown decay fungi and
saccharomycetes). A preparation method comprises airing and smashing, wherein the bean pulp, the turfy soil and the
bone meal are respectively smashed to 40 meshes to 60 meshes;
fermentation, wherein 5wt% to 10wt% of water is added to the smashed bean pulp, the smashed bone seal and the smashed turfy soil,
fermentation is conducted for 60 hours to 90 hours, and the temperature is controlled to be between 45 DEG C and 53 DEG C; and mixing according to proportion, wherein the raw materials are poured into a mixer. The mixed raw materials are prilled in a
machine, dried, dehumidified and packaged after being sufficiently stirred by adding 5wt% to 10wt% of water. The
plant biological
organic fertilizer has the advantages of replacing various types of chemical
fertilizer and compound
fertilizer effectively, improving the
soil structure, enabling the soil to recover to original
ecology and being capable of achieving a yield stabling and increasing effect.
