Abstract

The invention discloses a suspension type liquid fertilizer and a preparation method thereof. The suspension type liquid fertilizer comprises a dispersing agent, wherein the dispersing agent comprisesthe following components in percentage by mass: 80% of guar gum, 15% of xanthan gum and 5% of glucose, and the mass percentage content of the dispersing agent in the suspension type liquid fertilizeris 0.1-0.5%. The preparation method of the suspension type liquid fertilizer provided by the invention comprises the following steps: S1, according to the proportion of each component, adding a corresponding amount of water into a combined stirrer reaction kettle, and controlling the temperature to be 30-60 DEG C, the stirring speed to be 15-90 revolutions per minute, and the shear speed to be 1500-4500 revolutions per minute; S2, according to the proportion of each component, sequentially adding other raw materials into the combined stirrer reaction kettle spoon by spoon uniformly and dispersedly; and S3, after the feeding is finished, carrying out stirring for shearing for 25-35 minutes while carrying out cooling. According to the suspension type liquid fertilizer provided by the invention, 80% of guar gum, 15% of xanthan gum and 5% of glucose are used as the dispersing agent, strong emulsification stability and high suspension capability are achieved, and when the suspension type liquid fertilizer is placed at room temperature for 18 months, no solid sinking or caking occurs in the dispersion system, and the dispersion system is still in a stable state.

Description

technical field [0001] The invention relates to the technical field of liquid fertilizers, in particular to a suspension type liquid fertilizer and a preparation method thereof. Background technique [0002] Reasonable fertilization and integration of water and fertilizer are the general trend. With the promotion of water and fertilizer integration, traditional compound fertilizers can no longer meet the needs of modern agricultural production due to their slow dissolution rate, high insoluble matter and harmful ions, and water-soluble fertilizers have emerged as the times require. During the production process of powdered water-soluble fertilizer, nutrients are easy to be mixed and uneven, easy to segregate during transportation, resulting in nutritional imbalance, and easy to absorb moisture and agglomerate during production, transportation and storage. However, liquid fertilizer has high nutrient content, uniform concentration, and perfect docking with the integration of...
