Quick-dissolving fertilizer and preparation method thereof

Abstract

The invention relates to an organic and inorganic compound fertilizer applied to vegetable production, in particular to a quick-dissolving fertilizer and a preparation method thereof, wherein the quick-dissolving fertilizer comprises the following components in content by weight: 10-50 percent of ammonium nitro-humate, 0-40 percent of urea, 0-10 percent of ammonium nitrate or ammonium sulfate, 0-35 percent of monoammonium phosphate, 0-20 percent of potassium sulfate, 0-5 percent of magnesium sulfate, 0.5-1 percent of zinc sulfate and 0.3-0.8 percent of borax. The fertilizer disclosed by the invention has the effects of improving the structure and texture of soil, improving the soil fertility, improving the ventilation property and the water-retaining property, promoting the propagation and the growth of beneficial microorganisms, improving the stress resistance of crops and enhancing the drought-resisting (water-logging-resisting), cold-resisting and disease-resisting capabilities; and the quick-dissolving fertilizer is an ideal fertilizer for the production base of pollution-free foods.

Description

technical field

[0001] The invention relates to an organic-inorganic compound fertilizer used in vegetable production, in particular to an instant fertilizer and a preparation method thereof. Background technique

[0002] In vegetable production, due to the short growth time of vegetables, and at the same time, in order to obtain high yields, farmers put too much chemical fertilizers into the vegetable fields, accumulating throughout the year, the land is hardened, and various diseases are aggravated. Pollution of ground water.

[0003] In the prior art, conventional chemical nitrogen fertilizers have good water solubility and are easily lost after being applied to the soil. Ineffective state (especially in calcareous soil); therefore, it is necessary to develop and produce slow and controlled release fertilizers that can maintain the long-term effect of nitrogen fertilizer and reduce the fixation of phosphorus fertilizer.
