Abstract

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.

Description

technical field [0001] The invention relates to the field of natural plant sources and fertilizers with insecticidal effect, in particular to a slow-release fertilizer with natural insecticidal effect. technical background [0002] It has been recognized that chemical fertilizers play a pivotal role in increasing the yield of crops. At present, the utilization rate of chemical fertilizers is less than 30%, and the rest is lost with water and soil. The application of chemical fertilizers not only causes great waste, but also pollutes soil and groundwater resources. Therefore, the development of slow and controlled release fertilizers has been listed as a key development support project by the state. At present, fertilizers with slow and controlled release functions can only play a role in rational use of fertilizers and reduction of environmental pollution, but cannot be applied at one time. They can not only provide fertilizers for crops, but also serve the purpose of contr...
