Abstract

The invention discloses an environment-friendly fertilizer and a preparation method thereof, and belongs to the technical field of fertilizers. The environment-friendly fertilizer comprises the following raw materials in parts by weight: 50-80 parts of river bottom mud, 10-15 parts of straw, 15-25 parts of activated carbon, 20-30 parts of coal slag, 3-6 parts of earthworms, 25-35 parts of pig manure, 10-15 parts of fish bone and 0.1-0.5 part of lactic acid bacteria. According to the invention, the earthworms are added into the coal slag and the pig manure, and the ground fish bone and straw powder are added into the coal slag and the pig manure. The fish bone and the straw provide a good living environment for the earthworms, so that the growth of the earthworms is facilitated. The coal slag contains certain nutrient elements, but certain heavy metals exist in the coal slag, and heavy metals such as Cu, Zn, Cd, Ni and the like are promoted to be converted to an exchange state and a water-soluble state through the effect of the earthworms. The comprehensive effect of influence of the earthworms on the stage of the heavy metals is relatively remarkable, so that harmless use of the coal slag is realized, the waste is changed into wealth, and nutrients are provided for the growth of plants. In addition, a certain capability of fertilizer retention and water retention is achieved, and the long-time fertility-increasing effect of the fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to an environment-friendly fertilizer and a preparation method thereof. Background technique [0002] Fertilizer refers to a class of substances that provide one or more essential nutrient elements for plants, improve soil properties, and increase soil fertility levels. It is one of the material bases of agricultural production. [0003] Bottom mud is the sediment of rivers and lakes, and is an important part of natural waters. When waters are polluted, some pollutants in the water can be stored in the bottom mud through sedimentation or particle adsorption, and released under appropriate conditions, becoming a secondary pollution source. , This kind of pollution is called sediment pollution, but there are a lot of nutrients in the river sediment. If it can be used as plant fertilizer under harmless conditions, it is the resource utilization of waste. [0004] Coal slag, a kind...
