Example Embodiment

[0061] Example 1:

[0062] Sprayed humor solution: 600 parts of urea, 100 parts of ammonium sulfate, 300 parts of humic acid, 50 parts of water.

[0063] Solid granulation raw materials: 230 parts of urea, 193 parts of industrial monoammonium phosphate, 480 parts of potassium sulfate, 30 parts of ammonium bicarbonate, 5 parts of anhydrous magnesium sulfate, 5 parts of boric acid, 4 parts of EDTA chelated zinc, EDTA chelated iron 3 Parts, 2 parts EDTA chelated manganese, 2 parts EDTA chelated copper, 1 part ammonium heptamolybdate.

[0064] Step 1: Urea melting. Open the steam valve of the main pipe, open the urea melting tank and stir. First add 50 kg of water to the urea-based tank, then add urea and ammonium sulfate in proportion, and control the temperature of the urea-based tank at 115-125°C. After the stirring is completely melted, the urea solution reaches overflow. Flow liquid level, the overflow pipe has liquid flowing out, stop the urea dispensing.

[0065] Step 2: Prepara...

[0073] Solid granulation raw materials: 230 parts of urea, 193 parts of industrial monoammonium phosphate, 480 parts of potassium sulfate, 30 parts of ammonium bicarbonate, 22 parts of bentonite.

[0074] Step 1: Urea melting. Open the steam valve of the main pipe, open the urea melting tank and stir. First add 50 kg of water to the urea-based tank, then add urea and ammonium sulfate in proportion, and control the temperature of the urea-based tank at 115-125°C. After the stirring is completely melted, the urea solution reaches overflow. Flow liquid level, the overflow pipe has liquid flowing out, stop the urea dispensing.

[0075] Step 2: Preparation of fudiamide solution. When the liquid level in the urea melting tank reaches the position of the overflow pipe, the batching is stopped. Turn on the temperature of the reaction tank, heat...

Abstract

The invention discloses an activated humic acid formulated fertilizer special for sweet potatoes, and relates to the technical field of a formulated fertilizer special for crops. The activated humic acid formulated fertilizer is prepared from a raw material of a urea melt liquid for spraying activated humic acid and a raw material for solid granulation, wherein the urea melt liquid comprises urea, ammonium sulfate, humic acid, and water, and the raw material for solid granulation comprises urea, industrial monoammonium phosphate, potassium sulfate, ammonium bicarbonate, anhydrous magnesium sulfate, boric acid, ZnEDTA, FeEDTA, MnEDTA, CuEDTA, and ammonium heptamolybdate. According to the invention, the formulated fertilizer special for sweet potatoes is scientific in formula and comprehensive in nutrition. On the one hand, the added activated humic acid can buffer change of water, fertilizer, air, and heat in soil, and can reduce harmful effects on growth of sweet potatoes, so that the stress resistance of sweet potatoes is enhanced, on the other hand, the added activated humic acid contains a fulvic acid component, which can stimulate growth of sweet potatoes and enhance resistibility of sweet potatoes.

Description

technical field [0001] The invention belongs to the technical field of fertilizers specially formulated for crops, and in particular relates to a fertilizer specially formulated for sweet potatoes. Background technique [0002] Sweet potato, also known as sweet potato, white potato, sweet potato, sweet potato, sweet potato, etc., has the characteristics of wide adaptability, strong stress resistance, high yield, strong regeneration ability, and resistance to barrenness. Rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals, it has the reputation of "longevity food". The sugar content reaches 15%-20%. It has anti-cancer, heart protection, prevention of emphysema, diabetes, weight loss and other effects. Also commonly known as sweet potato, sweet potato. Li Shizhen's "Compendium of Materia Medica" in the Ming Dynasty records that "sweet potatoes tonic, invigorate the spleen and appetizers, strengthen the kidney yin", and said that people in ...
