Embodiment 1

[0020] 1) Weigh 100kg of urea, 210kg of potassium sulfate, 160kg of acid hydrolyzed amino acid solution, 230kg of superphosphate, 260kg of organic matter after harmless treatment, and 40kg of bentonite;

[0021] The organic matter after the above-mentioned harmless treatment is obtained by crushing animal manure such as chicken manure, horse manure, sheep manure, pig manure, etc., and fermenting for 15 days in a strip-type composting fermentation method. The first time is 6 days after stacking. Turn the pile, and then turn the pile once every 4 days, and air-dry the fermented organic matter until the water is 34% for later use;

[0022] The above-mentioned acid hydrolyzed amino acid solution is obtained in this way: adding H2 concentration of 2mol / L to feather powder and hair 2 SO 4 , so that the mass ratio of the material to the acid solution is 1.8: 1, and after acting for 70 hours at 70°C, add ammonia water to neutralize until the pH value is 4.0 and set aside;

Embodiment 2

[0025] 1) Weigh 110kg of urea, 200kg of potassium sulfate, 165kg of acid hydrolyzed amino acid solution, 220kg of superphosphate, 220kg of organic matter after harmless treatment, and 30kg of bentonite;

[0026] The organic matter after the above-mentioned harmless treatment is obtained in the following way: crush the straw and ferment it for 17 days in a warehouse-style composting fermentation method. For the first time, turn the pile 6 days after stacking, and then turn it every 4.5 days. The organic matter is dried until the moisture is 30% for later use;

[0027] The above-mentioned acid-hydrolyzed amino acid solution is obtained in the following way: the H concentration of 2mol / L is added to animal keratin proteins such as poultry feathers and feather stems. 2 SO 4 , make the mass ratio of material and acid solution be 1.9: 1, act at 75 DEG C for 65 hours, add ammonia water and neutralize until the pH value is 4.2 and set aside;

[0028] 2) First mix the weighed urea, o...

Embodiment 3

[0030] 1) Take 115kg of urea, 215kg of potassium sulfate, 170kg of acid hydrolyzed amino acid solution, 235kg of superphosphate, 240kg of organic matter after harmless treatment, and 35kg of bentonite;

[0031] The organic matter after the above-mentioned harmless treatment is obtained in the following way: crush chicken manure, pig manure, and straw, and ferment for 18 days in a strip-type composting fermentation method. Turn the pile once, and dry the fermented organic matter until the moisture is 25% for later use;

[0032]The above-mentioned acid hydrolyzed amino acid solution is obtained in this way: adding keratin proteins such as feather powder, hair, and animal hoof shells into H2O with a concentration of 2mol / L 2 SO 4 , make the mass ratio of material and acid solution be 2: 1, act under the condition of 85 ℃ for 60 hours, add ammonia water and neutralize until the pH value is 4.5 and set aside;

Abstract

The invention relates to an amino acid organic and inorganic special compound fertilizer for potatoes and a manufacturing method thereof. The compound fertilizer comprises the following components in percentage by mass: 10 to 13 percent of urea, 20 to 23 percent of potassium sulfate, 22 to 25 percent of calcium superphosphate, 22 to 28 percent of harmlessly treated organic substance, 16 to 18 percent of acid decomposed amino acid solution and 3 to 4 percent of bentonite. The compound fertilizer can meet the physiological demands of potato growth, provides nitrogen, phosphorus and potassium inappropriate proportion for the potato growth, and promotes the development of potato root systems by using amino acid, so that the potato roots fully absorb nutrition, the potato tubers are promoted to expand and the yield of the potatoes is improved; the used raw materials do not contain the components harmful for the growth and development of plants, the organic nutrients and the inorganic nutrients are combined reasonably, the slow-release period of the nutrients is increased, the utilization rate of the fertilizer is greatly improved, and the soil structure is improved, so the compound fertilizer is particularly suitable for one-time fertilization requirement of the potatoes; and in the manufacturing method, the raw material sources are wide, the manufacturing process is simple, the equipment is easily obtained, and the investment is low.

Description

technical field [0001] The invention relates to a fertilizer mixture, in particular to a potato amino acid organic and inorganic special compound fertilizer and a manufacturing method thereof. Background technique [0002] Potato is a herbaceous plant of the family Solanaceae, whose tubers are edible, and are important food and vegetable crops. Potatoes are currently the most important food crops used as human staple food in the world besides cereals. It is very adaptable to soil and is widely grown throughout the world. At present, nearly 5 million hectares of potatoes are planted in my country, but the yield per unit area is very low, with an average yield of less than 3,000 kilograms per hectare. This is not only related to potato cultivars and soil fertility, but also related to the current level of fertilization during potato planting. At present, in the process of planting potatoes, many farmers do not fertilize or use traditional phosphate fertilizer, common compoun...
