The invention relates to the technical field of organic fertilizers, and discloses a
eucalyptus extract-containing multifunctional bactericidal
fertilizer and a preparation method thereof, and the microcapsule-shaped multifunctional bactericidal
fertilizer is prepared by
coating an
organic fertilizer core material with a
coating layer, the
coating layer is divided into an inner layer and an outer layer, the inner layer is a slow-release antibacterial layer, and the outer layer is a microbial response layer; the
organic fertilizer core material is prepared from the following raw materials in parts by
mass: 40 to 60 parts of decomposed
organic matter, 10 to 20 parts of
urea, 8 to 15 parts of
monopotassium phosphate, 5 to 10 parts of diatomite and 10 to 15 parts of deionized water. The problems that a traditional product is low in
utilization rate and pollutes the environment are effectively solved, the
fertilizer efficiency and the antibacterial
time efficiency are prolonged through a slow release structure, the
utilization rate of active ingredients is increased by means of a
dual response mechanism, a practical solution is provided for green prevention and control of agricultural diseases and efficient fertilization, and remarkable technical advantages and application value are achieved.
