Embodiment 1

[0021] A preparation method of slow-release compound fertilizer, comprising the following steps:

[0022] 1) Prepare materials according to the following ratio:

[0023] Urea 20~30 parts

[0024] 20~30 parts of fermented liquid

[0025] Potassium dihydrogen phosphate 40~55 parts

[0026] Surfactant 5~10 parts

[0027] Chelating agent 8~15 parts

[0028] Plant growth regulator 0.02~0.05 parts

[0029] Cetearyl alcohol 0.4~1.0 parts

[0030] 2) Add urea, potassium dihydrogen phosphate, surfactant, chelating agent, plant growth regulator and cetearyl alcohol into the fermentation broth, stir evenly and dry to obtain slow-release compound fertilizer. The slow-release compound fertilizer of the present invention not only contains nitrogen, phosphorus, and potassium three major elements, but also contains abundant weight elements, trace elements, and various amino acids, which can meet the needs of plant growth, and can increase the concentration of 5-aminoketone in leaf surfa...

Embodiment 2

[0036] A most preferred preparation method of slow-release compound fertilizer, comprises the following steps:

[0037] 1) Prepare materials according to the following ratio:

[0038] 28 parts of urea

[0039] 25 parts fermented liquid

[0040] Potassium dihydrogen phosphate 50 parts

[0041] Surfactant 8 parts

[0042] Chelating agent 12 parts

[0043] Plant growth regulator 0.04 part

[0044] 0.7 parts of cetearyl alcohol

[0045] 2) Add urea, potassium dihydrogen phosphate, surfactant, chelating agent, plant growth regulator and cetearyl alcohol into the fermentation broth, stir evenly and dry to obtain slow-release compound fertilizer. The slow-release compound fertilizer of the present invention not only contains nitrogen, phosphorus, and potassium three major elements, but also contains abundant weight elements, trace elements, and various amino acids, which can meet the needs of plant growth, and can increase the concentration of 5-aminoketone in leaf surface cells....

Embodiment 3

[0051] A preparation method of slow-release compound fertilizer, comprising the following steps:

[0052] 1) Prepare materials according to the following ratio:

[0053] 20 parts of urea

[0054] 20 parts fermented liquid

[0055] Potassium dihydrogen phosphate 55 parts

[0056] Surfactant 7 parts

[0057] Chelating agent 10 parts

[0058] Plant growth regulator 0.02 part

[0059] 0.8 parts of cetearyl alcohol

[0060] 2) Add urea, potassium dihydrogen phosphate, surfactant, chelating agent, plant growth regulator and cetearyl alcohol into the fermentation broth, stir evenly and dry to obtain slow-release compound fertilizer. The slow-release compound fertilizer of the present invention not only contains nitrogen, phosphorus, and potassium three major elements, but also contains abundant weight elements, trace elements, and various amino acids, which can meet the needs of plant growth, and can increase the concentration of 5-aminoketone in leaf surface cells.

Abstract

The invention discloses a preparation method of controlled-release compound fertilizer. The controlled-release compound fertilizer is prepared from, by weight, 20-30 parts of urea, 20-30 parts of fermentation liquid, 40-55 parts of monopotassium phosphate, 5-10 parts of surfactant, 8-15 parts of chelating agent, 0.02-0.05 part of plant growth regulator and 0.4-1.0 part of cetostearyl alcohol, wherein the fermentation liquid is obtained by linked glycolysis of an EM fungicide and neutral protease. The fertilizer has the advantages that the controlled-release compound fertilizer contains not only major elements including nitrogen, phosphorus and potassium but also abundant weight elements, trace elements and various amino acids, can meet the growth demands of plants, improves the activity of5-aminolevulinic acid dehydratase and uroporphyrinogen III synthase in leaf surface cells, increases the synthesis rate of chlorophyll, promotes photosynthesis and accelerates the growth of the plants.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a preparation method of slow-release compound fertilizer. Background technique [0002] Chemical fertilizers are fertilizers used in existing agriculture. Since the macronutrient elements nitrogen, phosphorus, and potassium in the soil usually cannot meet the needs of crop growth, it is necessary to use chemical fertilizers containing nitrogen, phosphorus, and potassium to supplement them. In the micronutrient elements, except chlorine, which is not lacking in the soil, other nutrients need to be applied with trace element fertilizers. Any chemical fertilizer that contains only one nutrient element that can indicate the content is called a unit fertilizer, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, etc. Any chemical fertilizer that contains two or more of the three nutritional elements nitrogen, phosphorus, and potassium and whose content can ...
