Problems solved by technology

[0002] At present, potassium sulfate compound fertilizers do not contain organic matter, and the utilization rate of fertilizer efficiency is low. Long-term use may easily cause soil compaction.
Some potassium sulfate-type compound fertilizers containing organic matter use humic acid but have not been activated. The organic matter is insoluble in water and has poor activity and cannot be absorbed by plants.

Embodiment 1

[0024] A kind of nutritious fertilizer for fruit trees of the present invention is characterized in that comprising the proportioning of following parts by weight:

[0025] Weathered coal 30, sulfuric acid 24, ammonia gas 8, monoammonium phosphate 20, urea 5, potassium chloride 14, seaweed extract 3, zinc sulfate 5, borax 5; the sulfuric acid is industrial concentrated sulfuric acid with a concentration of 98%.

[0026] The seaweed is a mixture of one or more of kelp, sargassum, and Ascophyllum nodosum, and the seaweed extract is prepared by the following method. After the above seaweed is crushed, it is immersed in 1-2 times the weight of clear water, and the temperature is raised to 70-80°C, use potassium hydroxide to adjust the pH value to 8-8.5, keep warm and stir for 30 minutes, cool to room temperature and filter through a 200-mesh silk sieve to obtain the primary filtrate and primary filter residue; take the primary filtrate equal weight of water and inject the primary f...

Embodiment 2

[0033] In step D), the secondary filter residue obtained by preparing the seaweed extract is first dried and pulverized, and the remaining weathered coal, remaining monoammonium phosphate and urea are pulverized, and then the pulverized secondary filter residue, weathered coal, and monoammonium phosphate Put into the mixer together with urea, borax, and zinc sulfate for mixing, and after mixing evenly, send it to the granulator through a belt conveyor to roll and agglomerate the granulation slurry produced in step C) to form granules, and the granulated granular materials After drying, cooling, screening, measuring and packaging, the nutrient fertilizer for fruit trees is formed. All the other are with embodiment 1.

Embodiment 3

[0035] The ratio of parts by weight of the raw materials of the product is: 35 parts by weight of weathered coal, 25 parts sulfuric acid, 30 parts ammonia 10 monoammonium phosphate, 15 parts urea, 16 parts potassium chloride, 5 parts seaweed extract, 8 parts zinc sulfate and 3 parts borax. All the other are the same as embodiment 1 and embodiment 2.

Abstract

The invention belongs to the technical field of compound fertilizer production, and relates to a seaweed composition containing specific fertilizer for fruit trees and a preparation method thereof. The specific fertilizer is prepared by reasonably proportioning weathered coal, sulfuric acid, gasified ammonia, monoammonium phosphate, urea, potassium chloride, seaweed extract, zinc sulfate and borax, and granulating the obtained mixture by using a special process. The specific fertilizer is rich in organic matters and various trace elements, and has the characteristics of high utilization rate of fertilizer efficiency, long duration of fertilizer efficiency, and capability of facilitating the improvement of soil.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, and relates to a special fertilizer for fruit trees containing seaweed components and a preparation method thereof. Background technique [0002] At present, potassium sulfate-type compound fertilizers do not contain organic matter, and the utilization rate of fertilizer efficiency is low, and long-term use is likely to cause soil compaction. Some potassium sulfate-type compound fertilizers containing organic matter use humic acid but have not been activated. The organic matter is insoluble in water, has poor activity, and cannot be absorbed by plants. [0003] Weathered coal is a coal seam that is exposed on the surface or buried in the shallow part. It has been in contact with water and air for a long time, and has undergone long-term oxidation and hydrolysis weathering, making the coal loose and brittle, with light color and increased humidity. Great changes have taken ...
