Embodiment Construction

[0018] An organic-inorganic slow-release fertilizer comprising urea with a nitrogen content of more than 46%, monoammonium phosphate, potassium sulfate, and weathered coal, the monoammonium phosphate having a nitrogen content of more than 11%, P 2 o 5 The content exceeds 44%, the K in the potassium sulfate 2 O content exceeds 50%, nitrogen content in the weathered coal exceeds 11.57%, P 2 o 5 The content of more than 5.91%, K 2 The content of 0 exceeds 3.05% and the content of organic matter exceeds 55.42%.

[0019] A kind of manufacture method of organic-inorganic slow-release fertilizer, comprises the following steps:

[0020] (1) Crushing the raw materials;

[0021] (2) Mix the pulverized raw material with the ingredients;

[0022] (3) Granulate the material after mixing raw materials and ingredients, and use a disc granulator to granulate. The disc granulator rotates at a constant speed of 45r / min, and adjusts the inclination angle of the disc to make the material gr...

Abstract

The invention provides organic-inorganic slow release fertilizer and a production method thereof and belongs to the technical field of agricultural manufacturing. The organic-inorganic slow release fertilizer contains urea with the nitrogen content of more than 46 percent, monoammonium phosphate, potassium sulfate and weathered coal, wherein the nitrogen content of the monoammonium phosphate is greater than 11 percent and the content of P2O5 in the monoammonium phosphate is greater than 44 percent; the content of K2O in the potassium sulfate is greater than 50 percent; the nitrogen content inthe weathered coal is greater than 11.57 percent, the content of the P2O5 in the weathered coal is greater than 5.91 percent, the content of the K2O in the weathered coal is greater than 3.05 percentand the content of organic matters in the weathered coal is greater than 55.42 percent. By adopting the organic-inorganic slow release fertilizer, the utilization rate of the fertilizer can be increased and the environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural manufacturing, in particular to an organic-inorganic slow-release fertilizer and a manufacturing method thereof. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations (AFO), chemical fertilizers play a role of 40% to 60% in increasing crop yields. Increased fertilizer input is indispensable. However, a large number of studies have shown that the seasonal utilization rate of my country's farmland chemical fertilizers is only 3% to 35% for nitrogen fertilizers, 10% to 20% for phosphorus fertilizers, and 35% to 50% for potassium fertilizers, which are about 5 to 20 percentage points lower than similar foreign fertilizers. . Taking nitrogen fertilizer as an example, the annual loss of nitrogen is equivalent to more than 19 million tons of urea, equivalent to more than 38 billion yuan. [0003] It can be seen from the above that th...
