Aphid killing and inhibiting bio-fertilizer and preparation method of bio-fertilizer

Abstract

The invention belongs to the technical field of biological organic fertilizer, and specifically relates to an aphid killing and inhibiting bio-fertilizer which has inhibiting and killing effects on aphids of crops and a preparation method of the bio-fertilizer. The aphid killing and inhibiting bio-fertilizer provided by the invention is prepared by the following method: (1) crushing ailanthus altissima leaves and ailanthus altissima root barks in any proportion into power to form a component one; (2) crushing sunflower cakes, flax cakes, ailanthus altissima seed cakes, corncobs, bean dregs, starch residue and vinasse into powder to form a component two; (3) crushing sheep manure and chicken manure into powder to form a component three for standby; (4) mixing and stirring the component one, the component two and the component three to form a raw material mixture, then adding a biological fermentation agent into the raw material mixture, and performing uniform stirring to form a fermentation raw material; (5) adding urea, diammonium phosphate and potassium sulfate, performing uniform stirring and then performing granulation; and (6) drying the granules obtained by the granulation, and performing packaging to obtain the bio-fertilizer.

Description

technical field [0001] The invention belongs to the technical field of biological organic fertilizers, and in particular relates to an aphid-killing biological fertilizer capable of inhibiting and killing crop aphids and a preparation method thereof. Background technique [0002] Aphids, also known as greasy insects and honey insects, are a type of herbivorous insects. There are about 4,700 species of aphids in 10 families that have been discovered so far. Although aphids are small and soft, they are very fecund and harmful. Adult peach aphids suck fresh food 79 times their body weight within 24 hours; one adult aphid can produce 70 small aphids per generation, and can reproduce more than ten or even dozens of generations in a year. [0003] Aphids are one of the most destructive pests on earth. Aphid damage includes almost all plants of angiosperm and gymnosperm coniferae, even mosses and ferns; it is divided into winged and wingless types, with heterogeneous hosts, wide d...

Problems solved by technology

Among them, agricultural control mainly includes crop rotation, scientific use of organic fertilizers, scientific management, and suitable cultivation methods, etc.; physical control uses yellow boards, black light, sweet and sour liquid to lure and kill, etc.; biological control mainly uses natural enemies to prey, such as Predatory ladybugs, lacewings, spiders, hoverflies, aphids, etc. These methods have the advantage of reducing chemical pesticides and are conducive to protecting the environment, but they are time-consuming, labor-intensive, inefficient, and require high control technology. The effect is slow, and it is not easy to completely eliminate insect pests and other shortcomings
