Embodiment 1

[0018] The natural keratin compound fertilizer comprises: natural keratin raw materials, sulfate inorganic compounds, complexing agent, and its weight ratio is 75-85 parts of natural keratin raw materials, 12-20 parts of sulfate inorganic compounds part, 2-4 parts of complexing agent.

[0019] In the natural keratin compound fertilizer, the natural keratin raw materials include 20-22 parts by weight of pig hair, 15-20 parts of chicken feather, 5-8 parts of pig's hooves, and 15-20 parts of pig blood powder , 20-22 parts of pork bone meal.

[0020] In the natural keratin compound fertilizer, the sulfate inorganic compound comprises 4-6 parts by weight of copper sulfate, 4-6 parts of ferrous sulfate, 2-4 parts of manganese sulfate, and 1-3 parts of magnesium sulfate. share.

[0021] In the natural keratin compound fertilizer, the complexing agent comprises 2-4 parts of nitrogen, 1-3 parts of phosphorus and 2-4 parts of potassium in parts by weight.

Embodiment 2

[0023] The preparation method of natural keratin compound fertilizer is to ferment and modify the natural keratin raw materials according to the ratio of parts by weight in Example 1 to generate animal amino acids, and mix animal amino acids and the described copper sulfate and ferrous sulfate , manganese sulfate, and magnesium sulfate are put into a chelating tank for chelating, and then the chelate and the nitrogen, phosphorus, and potassium are put into a chelating tank for complexing to form liquid natural keratin compound fertilizer.

[0024] The preparation method of the natural keratin compound fertilizer, the fermentation modification adopts a 5000 liter fermenter, and in the temperature range of 30-35 ℃, lasts for 168 hours to generate animal amino acids; the chelation adopts 5000 Liter chelation tanks, in the temperature range of 80-110°C, continue for 12 hours to form chelates; the complexation uses a 5000-liter complexation tank, in the temperature range of 45-60°C,...

Embodiment 3

[0026] The preparation method of natural keratin compound fertilizer is to take 21 parts of pig hairs, 18 parts of chicken feathers, 6 parts of trotter shells, 18 parts of pig blood powder and 21 parts of pig bone powder according to the ratio of parts by weight to carry out fermentation and modification to generate animal amino acids, and then Animal amino acids and 5 parts of copper sulfate, 5 parts of ferrous sulfate, 3 parts of manganese sulfate, and 2 parts of magnesium sulfate are put into the chelation tank for chelation, and then the chelate and nitrogen 3 parts, phosphorus 2 parts, and potassium 3 parts Put it into a complexing tank for complexation to form a liquid natural keratin compound fertilizer.

[0027] The preparation method of the natural keratin compound fertilizer, the fermentation modification adopts a 5000 liter fermenter, and in the temperature range of 30-35 ℃, lasts for 168 hours to generate animal amino acids; the chelation adopts 5000 Liter chelatio...

Abstract

The invention relates to a natural keratin composite fertilizer and a method for preparing the same. The paddy seedling raising farming fertilizer at present has unqualified product quality and cannot be applied widely. The natural keratin composite fertilizer comprises the following components in portion by weight: 75 to 85 portions of natural keratin raw material, 12 to 20 portions of sulphate inorganic compound, and 2 to 4 portions of complexing agent. The natural keratin composite fertilizer is applied to paddy seedling raising farming fertilizer and the method for preparing the same.

Description

Technical field: [0001] The invention relates to an agricultural fertilizer for rice seedling raising and a preparation method thereof, in particular to a natural keratin compound fertilizer and a preparation method thereof. Background technique: [0002] The current agricultural fertilizer for rice seedling raising is not easy to adjust acidity, the production process is complicated, the production cost is high, the bioavailability is low, the chemical structure is unstable, the absorption is slow, and the product quality does not meet the requirements, so it cannot be widely used. Invention content: [0003] The purpose of the present invention is to provide a natural keratin compound fertilizer with short process line, high bioavailability and low cost and its preparation method. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] The natural keratin compound fertilizer comprises: natural keratin raw materials, sulfate inorganic compounds,...
