Problems solved by technology

[0002] Now the long-term excessive and single use of chemical fertilizers and pesticides in agricultural planting has led to soil nutrient imbalance, acidification, hardening, and salinization, especially the accumulation of nitrate in crops and vegetables, resulting in a decline in the quality of crop products
Moreover, the nitrogen and nitrate brought into the surface water by farmland runoff lead to serious eutrophication of the water and cause groundwater pollution.

Abstract

The invention discloses a composite ecological fertilizer which comprises the following raw materials: urea, monoammonium phosphate, potassic fertilizer, multi-composite mineral fertilizer, activated humic acid, plant ash and compound microbial fertilizer. According to the composite ecological fertilizer, nitrogen, phosphorus and potassium fertilizer, humic acid fertilizer, the multi-composite mineral fertilizer and the compound microbial fertilizer are combined into one; during application, time and labor can be saved; furthermore, the soil can be improved, the utilization rate of the fertilizer can be further increased, and the quality of agricultural products can be improved. The invention further discloses a preparation method of the composite ecological fertilizer.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a compound ecological fertilizer and a production method thereof. Background technique [0002] The long-term excessive and single use of chemical fertilizers and pesticides in agricultural planting has led to soil nutrient imbalance, acidification, compaction, and salinization, especially the accumulation of nitrate in crops and vegetables, resulting in a decline in the quality of crop products. Moreover, the nitrogen and nitrate brought into the surface water by farmland runoff lead to serious eutrophication of the water and cause groundwater pollution. In recent years, the majority of farmers urgently need to use diversified fertilizers to improve the quality of agricultural products, improve the soil and improve the utilization rate of fertilizers, especially the combined application of inorganic and organic fertilizers, which is of great signific...
