Embodiment 1

[0023] 1) Take bean cake and rapeseed cake and grind them to 20 mesh fine powder, put them in a reaction tank, add 60% sulfuric acid (volume concentration: 12%) and hydrolyze at 80°C for 8 hours. During the hydrolysis of sulfuric acid, every Stir every 1 hour for 5 minutes each time. After hydrolysis, add ammonium bicarbonate while stirring to adjust the pH to 4.5, discharge the material, and dry until the particles with a water content of <3% are obtained as organic fertilizers.

[0024] 2) Weigh 22.5kg of urea, 15kg of diammonium phosphate, 25kg of potassium nitrate, 0.1kg of boric acid, 0.1kg of zinc sulfate, 0.1kg of manganese sulfate and 80kg of organic fertilizer, mix and granulate (φ is 1mm).

Embodiment 2

[0026] 1) Take bean cake and rapeseed cake and crush them to 60 mesh fine powder, put them in a reaction tank, add 80% sulfuric acid (volume concentration: 18%) and hydrolyze at 100°C for 24 hours. During the sulfuric acid hydrolysis process, every Stir once every 2 hours for 15 minutes each time. After hydrolysis, add ammonium bicarbonate while stirring to adjust the pH to 5.5, discharge the material, and dry until the particles with a water content of <3% are obtained as organic fertilizers.

[0027] 2) Weigh 27kg of urea, 18kg of diammonium phosphate, 30kg of potassium nitrate, 0.5kg of boric acid, 0.4kg of zinc sulfate, 0.4kg of manganese sulfate and 120kg of organic fertilizer, mix and granulate (φ=5.5mm) to get ready.

Embodiment 3

[0029] 1) Take bean cake and rapeseed cake and crush them to 40 mesh fine powder, put them in a reaction tank, add 70% sulfuric acid (volume concentration: 16%) to hydrolyze at 90°C for 16 hours, during the hydrolysis of sulfuric acid, every Stir once every 1.5 hours, and stir for 10 minutes each time. After the hydrolysis, add ammonium bicarbonate while stirring to adjust the pH to 5, discharge the material, and dry until the particles with a water content of <3% are obtained as organic fertilizers.

[0030] 2) Weigh 25kg of urea, 16kg of diammonium phosphate, 27kg of potassium nitrate, 0.2kg of boric acid, 0.2kg of zinc sulfate, 0.2kg of manganese sulfate and 100kg of organic fertilizer, mix and granulate (φ is 3mm).

Abstract

The invention discloses a special allium sativum L. fertilizer and a preparation method thereof. The special allium sativum L. fertilizer comprises urea, diammonium phosphate, potassium nitrate, boric acid, zinc sulfate, manganese sulfate and an organic fertilizer. The preparation method comprises the following steps: 1) taking a bean cake and a rape seed cake to be crushed, and putting the crushed cakes into a reaction tank, adding sulfuric acid of which amount is 60%-80% that of the feed material, performing hydrolysis for 8-24 hours at 80-100 DEG C, adding ammonium bicarbonate while stirring after the hydrolysis to regulate the pH to 4.5-5.5, discharging, drying to get particles of which water content is less than 3% to obtain the organic fertilizer; 2) mixing the urea, the diammonium phosphate, the potassium nitrate, the boric acid, the zinc sulfate, the manganese sulfate and the organic fertilizer to be and granulated to obtain the special garlic fertilizer. The fertilizer prepared through the method can provide all nutrients for the growth of allium sativum L., in addition, the organic fertilizer and the inorganic fertilizers are reasonably proportioned, so that the soil fertility and the utilization rate of the fertilizers are remarkably increased, and the planted garlic is high in quality and yield.

Description

technical field [0001] The invention relates to a crop fertilizer, in particular to a special fertilizer for garlic and a preparation method thereof. Background technique [0002] Garlic (Allium Sativum L.) is a biennial herb of the genus Allium in the family Liliaceae. Garlic seedlings (garlic seedlings), flower stems (garlic moss) and bulbs (garlic head), as well as the green garlic and garlic yellow produced can be eaten. The content of phosphorus, sulfur, iron and other minerals and vitamin C is high. It is a vegetable that people often eat and daily life. One of the important condiments needed in the diet is a famous and special vegetable variety in our country. Tissues such as bulbs and lower leaf epidermis contain volatile propylene sulfide (commonly known as allicin), which has the functions of increasing appetite, appetizing and eliminating food, antibacterial and anti-inflammatory, anti-cancer, anti-cancer, and cardiovascular and other diseases. Garlic has been c...
