Water-soluble fertilizer synergistic composition as well as preparation method and application thereof

Abstract

The invention discloses a water-soluble fertilizer synergistic composition as well as a preparation method and application thereof. The water-soluble fertilizer synergistic composition takes yeast fermentation broth as a carrier, and comprises 300-350 parts of the yeast fermentation broth, 80-100 parts of humic acid , 65-80 parts of monoammonium phosphate, 70-80 parts of potassium sulfate, 130-140parts of urea and 10-15 parts of trace elements. The water-soluble fertilizer synergistic composition has the effects of balancing nutrition, effectively avoiding antagonism among elements and facilitating absorption and transportation of nutrient elements; and meanwhile, the composition has the effects of improving plant resistance, conditioning soil and improving the utilization rate of nitrogen, phosphorus and potassium. The water-soluble fertilizer synergistic composition is simple in production process, convenient to use, beneficial for large-scale popularization and application and favorable for root system development, promotes root system absorption and transferring of nutrient elements needed by plants, and remarkably promotes plant growth and development.

Description

technical field [0001] The invention relates to the technical field of water-soluble fertilizer synergism, in particular to a water-soluble fertilizer synergistic composition and its preparation method and application. Background technique [0002] Water-soluble fertilizer (Water Soluble Fertilizer, referred to as WSF), is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops. The key point is that it can be applied to facility agriculture such as drip irrigation, realize the integration of water and fertilizer, and achieve the efficiency of saving water, fertilizer and labor [0003] There are many defects in the existing water-soluble fertilizer technology: [0004] Water-soluble fertilizers have a short fertilizer effect period, which leads to frequent use. Ordinary water-soluble fertilizers are applied once every 7-10 days, about 3-10kg / mu each time. In such a short peri...

AI Technical Summary

Problems solved by technology

[0004] Water-soluble fertilizers have a short fertilizer effect period, which leads to frequent use. Ordinary water-soluble fertilizers are applied once every 7-10 days, about 3-10kg / mu each time. In such a short period of time, crop absorption is limited, resulting in a large accumulation of nitrogen, phosphorus, and potassium nutrients In the soil, problems such as secondary salinization, soil compaction, and soil acidification are becoming more and more serious, and even small old seedlings, dead sheds, and many diseases appear in some places.

2. The nutrient structure is unreasonable and cannot provide balanced nutrients for crops. After being applied to the soil, the active ingredients are unstable and easily leached or volatilized. The role of promoting crop growth and enhancing crop stress resistance is only to provide the necessary nutrients for crops, so that the utilization rate of water-soluble fertilizers cannot be improved as it should be

3. There are also many foreign and domestic studies on fertilizer synergists to improve fertilizer utilization, mainly from chemically synthesized nitrification inhibitors, urease inhibitors, and ammonia stabilizers, and plant growth regulators are also added to fertilizers. The ingredients are used as fertilizer synergists, but there are defects such as unstable effects, high toxicity, and great impact on crops, soil, and the environment.
