Abstract

The invention discloses a compound fertilizer capable of increasing soil porosity and a preparation method thereof, and solves the technical problem that in the prior art, waste fly ash is not used for preparing a compound fertilizer which can well prevent soil hardening, improve soil air permeability and enhance soil fertilizer and water permeation. The fertilizer comprises the following components in percentage by mass: 40-60% of fly ash, 10-25% of desulfurized gypsum, 30-50% of air-dried cow dung, 5% of phosphate-solubilizing bacterial liquid and 5% of potassium-releasing bacterial liquid. The fly ash is adopted to prepare the compound fertilizer, solid waste is consumed, meanwhile, the soil structure can be effectively improved, soil hardening is broken, and the soil porosity is increased; meanwhile, Si, Ca, S, Fe, Mg and the like in the fly ash are well utilized by the compound fertilizer, wherein the elements belong to citric acid soluble and soluble elements and can be directly absorbed and utilized by crops, so that yield increase of the crops is facilitated, and the yield is generally improved by more than 10%.

Description

technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, in particular to a compound fertilizer for increasing soil porosity and a preparation method thereof. Background technique [0002] The comprehensive utilization of fly ash is an important closed loop of the entire industrial chain of coal resource recycling. With the in-depth advancement of the national ecological civilization construction, the implementation of the "Solid Waste Pollution Prevention and Control Law" and the implementation of the national carbon neutral strategy, the comprehensive utilization of fly ash will become my country's thermal power solid waste comprehensive utilization has entered an important part of the high-quality development stage. At the same time, the annual discharge of desulfurization gypsum in my country exceeds 70 million tons, and has a tendency to increase year by year, which not only occupies a large amount of land resources, but als...
