The invention relates to the technical field of
biomass fertilizers, and particularly relates to a potato growing
biomass organic fertilizer and a preparation method thereof. The potato growing
biomass organic fertilizer comprises the following components in parts by weight: 80-100 parts of animal excrement, 60-80 parts of
straw, 90-120 parts of water
hyacinth, 10-20 parts of
vinasse, 30-50 partsof swill, 75-90 parts of bean pulp, 10-15 parts of an
organic phosphorus agent and 0.5-2 parts of a
fermentation agent. The potato growing biomass
organic fertilizer provided by the invention has thebeneficial effects that sufficient organic nutrients can be provided for potatoes, and through the absorption and utilization of the microbial
decomposition products and metabolites by the roots of the potatoes, the growth of the potatoes is stimulated and promoted, the amount of the potatoes is large, the growth is uniform, the surface is smooth, the potatoes are plentiful and beautiful, and drought and flood resistance and cold and
heat resistance are achieved. Through
mass propagation of beneficial microorganisms in soil, the organic
nitrogen content of the soil can be increased, the activity and the effectiveness of
phosphorus and
potassium in the soil are promoted, and effects of
nitrogen fixation,
phosphorus dissolving and
potassium dissolving can be exerted, so that the utilizationrate of
fertilizer is improved, and the produced potatoes can be more plentiful in
nutrient.
