Ecological functional compound fertilizer and preparation method thereof

Abstract

The invention belongs to the field of fertilizers for crops and particularly relates to an ecological functional compound fertilizer and a preparation method thereof. The ecological functional compound fertilizer is prepared from the following main components: sludge, a compound fertilizer, a microbial agent, an organic waste, a soil heating agent and an oxygen supplier. The sludge obtained from the treatment of municipal domestic wastewater and the organic waste serve as organic matters, contain multiple nutrients and can be combined with the compound fertilizer to increase the utilization rate of the compound fertilizer and increase the content of organic matters in soil; the added soil heating agent can preserve the temperature around the roots of crops in deep soil and prevent crops from being frostbitten and frozen to death; the added oxygen supplier can supply oxygen to microorganisms in soil and cells in crop roots to increase the activity of the microorganisms in soil and the crop roots, accelerate the absorption of the ecological compound fertilizer, enhance the adversity, disease and cold resistance of crops, improve the structure and fertility of soil and promote the growth of crops; the pollution of sludge to environment can be reduced, and the sludge can be reutilized; and the ecological compound fertilizer is safe to people, animals and environment and is natural, innoxious and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of crop fertilizers, and more precisely relates to an ecologically functional compound fertilizer and a preparation method thereof. Background technique [0002] Ecological fertilizer is an environmentally friendly fertilizer, which contains a large amount of organic matter. Applying it to the soil can promote the activity of microorganisms in the soil, enhance the ability of crops to resist stress and disease, reduce crop repeated cropping, and apply it year after year. It can greatly alleviate the obstacles of continuous cropping and improve agricultural products. Quality; it can also improve the soil structure, increase the porosity of the soil, improve the permeability of the soil, prevent soil compaction, enhance the respiration of microorganisms and crop roots in the soil, promote crop growth, and improve soil fertility; at the same time, it can reduce water loss and evaporation , Relieve the pressure of drought...

Problems solved by technology

[0005] According to the above, my country's current thermal insulation fertilizers are mainly covered with sand, inorganic minerals or agricultural waste, while oxygen supply fertilizers mainly improve soil permeability and oxygen supply by adding inorganic minerals, but increasing permeability While increasing the oxygen supply, the water in the soil evaporates faster, taking away part of the heat in the soil, resulting in a sudden drop in temperature
