Problems solved by technology

[0005] The disadvantage of drip irrigation and fertilization is that the drippers are easy to scale and block, so the water source should be strictly filtered, so the requirements for water-soluble fertilizers are also relatively high
However, the existing water-soluble fertilizers contain more water-insoluble residues, which are easy to cause blockage and directly affect the use of the entire drip irrigation system.
Moreover, the nutrients are not balanced, and several kinds of fertilizers are often used in combination, which is inconvenient to apply, and leads to slow or incomplete dissolution of water-soluble fertilizers, which directly affects the use of water-soluble fertilizers and the effectiveness of fertilizers.

Abstract

The invention provides organic granular water-soluble fertilizer and a preparation method thereof, and relates to the field of fertilizer. The organic granular water-soluble fertilizer comprises the following components in parts by weight: 65 to 70 percent of ammonium sulfate, 9 to 14 percent of urea, 5 to 10 percent of potassium nitrate, 5 to 6 percent of monoammonium phosphate, 2.5 to 5 percentof potassium fulvic acid, 3 to 4.5 percent of magnesium sulfate, 1.5 to 2 percent of molasses liquid, 0.2 to 1.2 percent of trace element, 0.5 to 5 percent of tripotassium phosphate and 0.5 to 2 percent of ethanediamine sodium dio-phenyl acetate. The organic granular water-soluble fertilizer has rich and balanced nutrition, and can effectively reduce the water-insoluble matter content, rapidly increase the dissolution speed, increase the utilization rate of the fertilizer and avoid blockage of a drop irrigation pipeline.

Description

technical field [0001] The invention relates to the field of planting agricultural and forestry crops, in particular to an organic granular water-soluble fertilizer and a preparation method thereof. Background technique [0002] With the rapid development of my country's agriculture, the consumption of water and fertilizer resources is becoming more and more serious, which also has an impact on the environment. Therefore, saving water and fertilizer is of great significance to the sustainable development of my country's agriculture. The current water and fertilizer integration fundamentally solves this problem. It not only realizes high-efficiency agriculture, but also saves water resources, improves the utilization rate of chemical fertilizers, and reduces the pollution of chemical fertilizers to water. [0003] Water-soluble fertilizer is a new type of high-efficiency fertilizer that can be completely dissolved in water. Because it can be quickly dissolved in water, it i...
