Problems solved by technology

[0004] Although traditional farm organic fertilizers do not have the disadvantages of inorganic fertilizers, they are piled up in front of and behind houses or on both sides of roads for a long time. The natural fermentation time is long, and it affects environmental sanitation, pollutes the air, causes harmful bacteria to multiply, and is harmful to the health of humans and animals. In addition, farmyard manure is time-consuming and labor-intensive when accumulating manure and fertilizing, and the amount is large, and the variety is single and the nutrients are not complete.

Abstract

The invention relates to an organic fertilizer and a preparation method. The fertilizer is prepared from the ingredients in parts by weight: 30-45 parts of chicken manure, 15-25 parts of cattle manure, 12-25 parts of pig manure, 10-13 parts of peat soil, 15-20 parts of straw ash, 15-20 parts of peat, 10-15 parts of oil cakes, 5-8 parts of animal bone meal, 6-8 parts of egg-shell meal, 3-5 parts of gypsum powder, 2-4 parts of dicalcium phosphate and 0.5-0.8 part of EM microbial agent. According to the fertilizer, the heavy-metal index is far lower than that of national standards, the nutrient requirements of crops can be met, meanwhile, slightly acidic and hardening phenomena of soil caused by long-term application of inorganic-salt fertilizers can be improved, and the pollution to environments due to the fact that the inorganic-salt fertilizers cannot be absorbed by the crops in the hardened soil, are lost and enter a groundwater zone can be avoided.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers, or chemical fertilizers for short. It has the characteristics of simple ingredients, high content of active ingredients, easily soluble in water, fast decomposition, and easy absorption by roots, so it is called "quick-acting fertilizer". Inorganic fertilizers and chemical fertilizers are widely used by farmers because of their high nutrient content and rapid fertilizer efficiency. However, long-term and large-scale application of chemical fertilizers often leads to environmental pollution. Due to the long-term application of inorganic salt compound fertilizers, the soil is...
