The invention relates to the technical field of organic fertilizers, in particular to a needle
mushroom residue-based fermented
organic fertilizer for watermelon planting and a preparation method thereof, the needle
mushroom residue-based fermented
organic fertilizer comprises needle
mushroom residues, modified
vegetable oil residues, compound bacterial
powder, functional auxiliary materials,
humic acid and
inorganic nutrient elements; through reasonable proportioning of the components and
process optimization, multiple effects are realized: on one hand, agricultural wastes such as the needle mushroom dregs and the
pleurotus eryngii dregs are used as raw materials, so that resource recycling is realized, and the production cost of the
fertilizer is reduced; on the other hand, through the synergistic effect of all the components, comprehensive
nutrient supply needed by watermelon growth is guaranteed, the
fertilizer utilization rate is increased, the
soil structure can be improved, the soil micro-
ecological environment can be adjusted, and the
soil fertility can be enhanced; meanwhile, the use of chemical fertilizers is reduced, the risk of environmental
pollution is reduced, the planted watermelon fruits are excellent in quality and good in taste, and an
effective solution is provided for green planting of watermelons.
