Abstract

The invention discloses humic acid benefiting and swelling compound fertilizer. The humic acid benefiting and swelling compound fertilizer is prepared from, by weight, 200-220 of urea, 40-60 parts ofammonium chloride, 400-450 parts of potassium chloride, 200-240 parts of monoammonium phosphate, 5-12 parts of humic acid, 5-10 parts of magnesium sulfate, 5-10 parts of chelated calcium, 3-5 parts ofchelated zinc, 3-5 parts of chelated iron, 3-5 parts of chelated manganese, 25-29 parts of a molecular sieve and 22-28 parts of activated carbon. After the compound fertilizer is applied to soil, humic acid and other trace elements can be released to the soil slowly, sustainably and stably, and utilization rate of the fertilizer is increased.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer preparation, and in particular relates to a humic acid-stimulated fruit-expanding compound fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizer is a very important part of agricultural production. The quality of chemical fertilizer can determine the yield of crops and affect the economic income of farmers. Compound fertilizer is the amount of at least two of the three nutrients nitrogen, phosphorus and potassium. Fertilizers made only by chemical methods are a kind of compound fertilizers. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It plays a very important role in balancing fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. [0003] Humic acid is the remains of animals and plants, mainly the remains of plants, which i...
