Embodiment 1

[0018] First, fully mix 2kg of polyaspartic acid with 325kg of urea, 240kg of monoammonium phosphate, 305kg of potassium chloride, 85kg of sulfur, 3kg of filler, etc., then pulverize and stir. Then add urea-formaldehyde solution spray (first inject the formaldehyde solution into the urea-formaldehyde preparation tank through the formaldehyde solution pump, after stirring, inject the molten urea with a concentration of 96.5% through the molten urine pump to fully mix it with the formaldehyde solution, and then add the concentration 50% NaOH solution, adjust the pH value of the mixture to 7.2; finally inject steam to raise the final temperature to 75°C. After 30-45 minutes of reaction, a urea-formaldehyde solution will be generated, of which 40kg of urea-formaldehyde), the material Mix and granulate in a drum granulator, dry through a drum dryer, and then pass through sieving and packaging to produce finished products. The product has a particle size (3.35mm-5.60mm) of 92%, smoo...

Embodiment 2

[0029] First, fully mix 4kg of polyaspartic acid with 339kg of urea, 227kg of monoammonium phosphate, 300kg of potassium chloride, 74kg of sulfur, and 6kg of filler, then pulverize and stir. Then add urea-formaldehyde solution spray (first inject the formaldehyde solution into the urine formaldehyde preparation tank through the formaldehyde solution pump, after stirring, inject the molten urea with a concentration of 96.5% through the molten urine pump to fully mix it with the formaldehyde solution, and then add the concentration 50% NaOH solution, adjust the pH value of the mixture to 7.2; finally inject steam to raise the final temperature to 75°C. After 30-45 minutes of reaction, a urea-formaldehyde solution will be generated (50kg of urea-formaldehyde). Mix and granulate in a drum granulator, dry through a drum dryer, and then pass through sieving and packaging to produce finished products. The product has a particle size (3.35mm-5.60mm) of 92%, smooth particles, strong cr...

Embodiment 3

[0032] Firstly mix 6kg polyaspartic acid with 356kg urea, 215kg monoammonium phosphate, 290kg potassium chloride, 64kg sulfur, etc., then pulverize and stir. Then add urea-formaldehyde solution spray (first inject the formaldehyde solution into the urine formaldehyde preparation tank through the formaldehyde solution pump, after stirring, inject the molten urea with a concentration of 96.5% through the molten urine pump to fully mix it with the formaldehyde solution, and then add the concentration It is 50% NaOH solution, adjust the pH value of the mixture to 7.2; finally inject steam to raise the final temperature to 75°C. After 30-45 minutes of reaction, a urea-formaldehyde solution will be generated, of which 60kg of urea-formaldehyde), the material Mix and granulate in a drum granulator, dry through a drum dryer, and then pass through sieving and packaging to produce finished products. The product has a particle size (3.35mm-5.60mm) of 92%, smooth particles, strong crush r...

Abstract

The invention belongs to the technical field of fertilizer production and in particular relates to a special functional urea formaldehyde fertilizer for garlic and a preparation method thereof. Each ton of the fertilizer is prepared from the following raw materials: 5kg-15kg of polyaspartic acid, 40kg-60kg of urea formaldehyde, 325kg-356kg of urea, 215kg-240kg of monoammonium phosphate, 290kg-305kg of potassium chloride and 64kg-85kg of sulfur. The fertilizer is rich in nutritional elements such as nitrogen, phosphorus, potassium, sulfur and the like necessary for the garlic and meets the growth and development needs of the garlic, and the yields of young garlic shoots and garlic bulbs are increased by 19% and 16% respectively in comparison with reference yields; the utilization rate of the fertilizer can be increased, and the utilization rates of nitrogen, phosphorus and potassium are increased by 18.0%, 15.7% and 13.7% respectively in comparison with those of nitrogen, phosphorus, potassium in a general fertilizer, so that the fertilizer consumption is reduced and the fertilizer effect is lasting; the disease resistance of the garlic is improved, and the diseased plant rate is reduced by 73.7% in comparison with that of reference garlic; the fertilizer is nontoxic, pollution-free and free of ecological environment damage.

Description

(1) Technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a special fertilizer with urea-formaldehyde functional garlic and a preparation method thereof. (2) Background technology [0002] Shandong Province is a large garlic-producing province, not only the production base of the domestic garlic market, but also the world garlic base. The purpose of garlic fertilization is to improve the yield and quality of garlic. In the current main cultivation system, fertilization not only determines the yield of garlic, but also affects the quality and yield of garlic sprouts. In recent years, garlic producing areas such as Cangshan and Jinxiang have invested a large amount of chemical fertilizers to increase the yield of garlic in order to pursue high yield and high efficiency. Traditional fertilizer types and fertilization methods have caused waste of fertilizer resources; soil compaction and deterioration of physic...
