Humic acid fertilizer composition and application thereof, and humic acid soluble fertilizer and application thereof

Abstract

The invention discloses a humic acid fertilizer composition and application thereof, and a humic acid soluble fertilizer and application thereof. The humic acid fertilizer composition comprises, by weight, 4-10 parts of potassium fulvic acid, 0.4-20 parts of sugar alcohol and 4-12 parts of organic potassium acid. The technical threshold of application of the humic acid fertilizer is reduced, fertilization mode is simplified, and safety and convenience in agricultural production are both guaranteed. With synergistic effect of the humic acid fertilizer composition, growth of plant roots is improved, content of vitamin C and soluble sugar is increased, yield and quality of plants are both increased, and yield increasing effect keeps stable.

Description

technical field [0001] The invention relates to the field of water-soluble fertilizers, in particular to a humic acid fertilizer composition, a humic acid water-soluble fertilizer and applications thereof. Background technique [0002] The utilization rate of chemical fertilizers in my country is low, only about 35%, the utilization rate of nitrogen fertilizer is about 30% to 35%, that of phosphorus fertilizer is 10% to 20%, and that of potassium fertilizer is about 35% to 50%. Excessive application of chemical fertilizers leads to unbalanced soil nutrients. After application, chemical fertilizers that are not absorbed by plants accumulate in the soil or flow into groundwater, which not only wastes resources, but also causes serious pollution to the environment. In recent years, in the process of agricultural production, the problem of environmental pollution caused by excessive application of chemical fertilizers has attracted widespread attention. [0003] The humic acid ...

Problems solved by technology

Although it helps to reduce sedimentation or flocculation, the amount of chelating agent added is large, the anti-flocculation effect is limited, and non-nutrient components are added to the nutrient solution, resulting in increased production costs and reduced effective components.

[0005] Moreover, different plants have different requirements for fertilizer concentrations, and the application of high-concentration humic acid fertilizers often causes fertilizer damage, which limits the use of humic acid fertilizers
