Fertilizer synergistic agent and preparation method thereof

Abstract

The invention discloses a fertilizer synergistic agent. The fertilizer synergistic agent is composed of the following components in percentages by mass: 30 to 50% of an organic carbon source, 3 to 5%of an organic nitrogen source, and 3 to 5% of beneficial microorganisms, with the balance being mineral trace elements. The fertilizer synergistic agent provided by the invention improves the utilization rate of a fertilizer, purifies soil, guarantees a good environment for the growth of a root system, and achieves a novel environment-friendly, fertilizer-decreasing and synergistic planting idea.The invention also discloses a preparation method for the fertilizer synergistic agent. The preparation method comprises the following steps: subjecting the organic carbon source, the organic nitrogensource, the beneficial microorganisms and the mineral trace elements to fermentation at a normal temperature for 7 to 15 days, then carrying out aging for 45 days, and carrying out fertilization treatment for 15 days. The preparation method provided by the invention is simple, easy and highly-efficient; meanwhile, the fertilizer synergistic agent prepared by using the preparation method providedby the invention overcomes the disadvantages of a chemical fertilizer; and a novel path with science, safety, high efficiency, environmental protection, low investment and high benefits is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemicals, and in particular relates to a fertilizer synergist, and also relates to a preparation method of the fertilizer synergist. Background technique [0002] In recent years, the use of chemical fertilizers has been increasing, soil fixation and water-soluble loss are serious, resulting in serious soil compaction and river eutrophication, large soil fertilizer storage, low utilization rate, weakened plant root system, poor resistance, low yield and poor quality. Water gathers in rivers and fertilizes water quality, which brings health risks to human drinking water. [0003] The following are several low-efficiency fertilizer usage conditions that often appear: Nitrogen fertilizer is applied, and 30% of nutrients are volatilized; water-soluble nutrients are watered after fertilization, and more than 30% of nutrients are infiltrated; phosphorus and potassium fertilizers are used alone, an...
