Problems solved by technology
However, due to the fine particles of the product, mechanical fertilization cannot be applied, and the fertilization will be scattered with the wind, causing large losses, polluting the environment, and high labor intensity. Particles are more difficult to dissolve in water, so that they cannot be absorbed by plants

Embodiment 1
[0038] The preparation technology of the dispersed type silicon calcium magnesium potassium granular fertilizer that the embodiment of the present invention 1 provides comprises the following steps:
[0039] (1) The zeolite, activated carbon, ammonium sulfate, humate, papermaking liquid sediment, alkyl sulfonate, silicon calcium magnesium potassium fertilizer are subjected to crushing pretreatment respectively, and the crushed pretreated zeolite, activated carbon, ammonium sulfate, humic acid The particle size of acid salt, papermaking liquid sediment, alkyl sulfonate, silicon calcium magnesium potassium fertilizer is controlled at 80 mesh;
[0040] (2) The pretreated zeolite, activated carbon, ammonium sulfate, humate, papermaking liquid sediment, and alkylsulfonate were pulverized and pretreated respectively, and the weight ratio was 12:15:15:18:25:15 Mix to obtain a dispersant;
[0041](3) weighing and mixing the dispersant and the powdered silicon-calcium-magnesium-potass...

The invention discloses a dispersed silicon-calcium-magnesium-potassium granular fertilizer and a preparation process thereof, and belongs to the technical field of agricultural fertilizers. The granular fertilizer is mainly formed by mixing and processing a dispersing agent and a powdery silicon-calcium-magnesium-potassium fertilizer according to the weight ratio of (10-25): (75-90); wherein thedispersing agent is formed by mixing zeolite, activated carbon, ammonium sulfate, a humate, papermaking liquid precipitate and alkyl sulfonate after crushing pretreatment. The invention discloses thedispersed silicon-calcium-magnesium-potassium granular fertilizer. Environmental pollution and nutrient loss caused by the fact that a powdery silicon-calcium-magnesium-potassium fertilizer drifts away along with wind during application can be avoided; it is beneficial to mechanical fertilization, the production efficiency is increased, the labor cost is reduced, supplement of nutrient elements required by plant growth is realized, the crop yield is increased, the quality of agricultural products is improved, has the characteristics of short flow, low investment and good product effect, and the fertilizer is suitable for popularization and application.
Description
technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a dispersed silicon-calcium-magnesium-potassium granular fertilizer and a preparation process thereof. Background technique [0002] At present, silicon-calcium-magnesium-potassium fertilizers on the market are generally made of potassium feldspar with dolomite, additives, etc. as the main raw materials, and are prepared by high-temperature melting. The migration of the plant is very small, and it is generally applied in the form of a fine powder of more than 80 meshes to fully contact the roots of the plants. It is decomposed by the weak acid secreted by the roots of the plants, and its nutrients are then absorbed by the plants to promote plant growth. However, due to the fine particles of the product, mechanical fertilization is not possible, and the fertilization will be scattered by the wind, resulting in large losses, polluting the environment, and high labo...
