The invention discloses a
controlled release fertilizer with a natural insecticide
efficacy. The
controlled release fertilizer takes chemical
fertilizer as
controlled release fertilizer core, and the controlled release fertilizer core is wrapped by
coating material into micro capsules, the micro capsules are wrapped by natural
plant decomposed materials and processed into granular controlled release fertilizer with the natural insecticide
efficacy and the particle size of 1-4.75 mm or 3.35-5.60 mm after being dried; the natural
plant decomposed materials comprise
powder material after being crushed, decomposed and dried, wherein the
powder material is tea seed residue after oil squeezing and / or tobacco waste after cigarette
processing, and the amount of the natural
plant decomposed material in weight percentage is 5-68.9%; according to the controlled release fertilizer with the natural insecticide
efficacy, the active ingredients in the fertilizer are continuously and slowly released to the environment; and the purposes of fertilization and insecticide are realized through one-time application, the fertilizer not only has the property of controlled release, but also has insecticide material with natural efficacy, and the problem of resistance of chemical
pesticide cannot be caused easily. The controlled release fertilizer is nontoxic for human and
livestock and has no residue. Finally, the plant source waste can additionally provide organic
nitrogen and
potassium fertilizer for crops, waste is trolley converted into useful things, and the
pollution to the environment is greatly reduced.
