Embodiment 1

[0022] For the ecological organic compound fertilizer used in lawn, nursery and forest trees, it is made according to the following weight ratio:

[0023] 132kg of urea, 177kg of monoammonium phosphate, 135kg of potassium chloride, 464kg of lignite, 100kg of trace elements, 1kg of probiotics and 1kg of probiotic liquid culture medium.

[0024] The preparation technology of ecological organic compound fertilizer comprises the following steps:

[0025] a. Use steam to heat urea, heat at 105°C for 5 minutes, add lignite to molten urea, react for 1 minute, then add monoammonium phosphate, potassium chloride, and trace elements to mix to obtain a mixed melt;

[0026] b. Pour the mixed melt into a granulator for granulation, and then naturally cool to 20°C;

[0027] c. Screening the obtained materials, the materials with a particle size of 2 to 4 mm are used as semi-finished products for standby, and the operation of step b is repeated for the remaining materials;

[0028] d. Pour...

Embodiment 2

[0031] For the ecological organic compound fertilizer that wheat, corn, paddy rice, sorghum are used, it is made according to the following weight ratio:

[0032] 248kg of urea, 309kg of monoammonium phosphate, 165kg of potassium chloride, 256kg of lignite, 30kg of trace elements, 1kg of probiotics, and 1kg of probiotic liquid culture medium.

[0033] The preparation technology of ecological organic compound fertilizer comprises the following steps:

[0034] a. First pulverize the lignite to 60 mesh, dry it at 100°C for 1 min, then pulverize the obtained lignite again until the particle size is 200 mesh,

[0035] Then put the urea in the container, heat the urea with a heating wire, heat at 140°C for 1 minute, add 200 mesh lignite into the molten urea, react for 15 minutes, and then add monoammonium phosphate, potassium chloride, and trace elements to mix;

[0036] b. Add the obtained mixed molten material into the high tower granulator for granulation, the molten material is...

Embodiment 3

[0041] The ecological organic compound fertilizer used for fruit trees and economic crops is made according to the following weight ratio:

[0042] 230kg of urea, 170kg of monoammonium phosphate, 120kg of potassium chloride, 80kg of potassium sulfate, 373kg of lignite, 30kg of trace elements, 1kg of probiotics, and 1kg of probiotic liquid culture medium.

[0043] The preparation technology of ecological organic compound fertilizer comprises the following steps:

[0044] a. First pulverize the lignite to 40 mesh, dry it at 60°C for 3 minutes, and pulverize the obtained lignite again until the particle size is 80 mesh,

[0045] Then put the urea in a container, heat the urea with steam, heat at 130°C for 2 minutes, add 80-mesh lignite into the molten urea, react for 10 minutes, and then add monoammonium phosphate, potassium chloride, potassium sulfate, trace elements mix;

[0046] b. Add the obtained mixed melt into the high tower granulator for granulation, the molten materia...

Abstract

The invention provides ecological organic composite fertilizer, which relates to the technical field of fertilizer. The ecological organic composite fertilizer is prepared by mixing and granulating molten nitrogenous fertilizer and other raw materials. The ecological organic composite fertilizer comprises the following components in parts by weight: 130 to 385 parts of nitrogenous fertilizer, other raw materials mainly comprise 120 to 330 parts of phosphorous fertilizer, 90 to 330 parts of potassium fertilizer and 230 to 470 parts of lignite, and the nitrogenous fertilizer is urea or ammonium nitrate nitrogenous fertilizer. The ecological organic composite fertilizer is less in moisture, high in finished product strength and good in application effect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to ecological organic compound fertilizers. Background technique [0002] Humic acid fertilizer is a kind of organic fertilizer used as crop base fertilizer or topdressing fertilizer. It plays an important role in improving soil structure and physical and chemical properties, improving soil fertilizer and water retention capacity, and activating the activity of probiotics in soil. It can chelate heavy metals in the soil, block the absorption of heavy metals by crops, and prevent heavy metals from entering the human food chain. It can promote plant growth, improve plant disease resistance, and improve crop yield and quality. It is an important part of modern ecological agriculture. . [0003] Therefore, in the existing industry, humic acid is often used to make fertilizers, and among the various forms of compound fertilizers made of humic acid, farmers prefer to use granular com...
