Problems solved by technology

[0011] 1. Most of them are ordinary inorganic fertilizers. Long-term use will cause the soil to become compacted, the soil fertility will be weakened, and the aggregate structure of the soil will be seriously damaged;
[0012] 2. Uneven fertilizer nutrients;
[0013] 3. Insufficient nutrition, generally does not contain sulfur, magnesium, boron, iron, zinc, manganese, copper and other medium and trace elements that can significantly improve the yield and quality of sweet potatoes, resulting in low yield and quality decline of sweet potatoes;
[0014] 4. The ratio does not meet the law of fertilizer requirements of sweet potatoes;
[0015] 5. The humic acid added in the humic acid compound fertilizer has not been activated, so it cannot play a good role in soil improvement

Embodiment 1

[0062] Sprayed humic urea liquid: 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, 3 parts of EDTA chelated iron 2 parts, 2 parts of EDTA chelated manganese, 2 parts of EDTA chelated copper, 1 part of ammonium heptamolybdate.

[0064] Step 1: Melting urea. Open the steam valve of the main pipe, start the urea melting tank to stir, first add 50 kg of water to the urea-based tank, then add urea and ammonium sulfate in proportion, control the temperature of the urea-based tank at 115-125 ° C, after stirring completely melted, the urea liquid reaches overflow If there is liquid flowing out from the overflow pipe, stop dispensing urea.

[0065] Step 2: Prepare the saprope...

Embodiment 2

[0072] Sprayed humic urea liquid: 600 parts of urea, 100 parts of ammonium sulfate, 300 parts of humic acid, 50 parts of water.

[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: Melting urea. Open the steam valve of the main pipe, start the urea melting tank to stir, first add 50 kg of water to the urea-based tank, then add urea and ammonium sulfate in proportion, control the temperature of the urea-based tank at 115-125 ° C, after stirring completely melted, the urea liquid reaches overflow If there is liquid flowing out from the overflow pipe, stop dispensing urea.

[0075] Step 2: Prepare the sapropenic urea solution. When the liquid level in the urea melting tank reaches the position of the overflow pipe, stop batching. Turn on the heat preservation and steam valve of the reaction tank, turn on the stirring ...

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 ...
