Problems solved by technology

[0002] Compound fertilizers are made by chemical methods and contain two or more nutrients. The compound fertilizers currently on the market use nitrogen, phosphorus, and potassium as the main raw materials, and some of them also add some phosphogypsum. Such filling materials are used to increase the weight. After applying these compound fertilizers, the initial growth effect of the crops is good, but in the mid-term, when the crops are flowering and pollinating, filling and graining, and late grain maturity, the fertilizer effect cannot keep up. The main reason is that Nitrogen, phosphorus, and potassium nutrients in chemical fertilizers are quickly decomposed and released after being soaked in water and soil solution, while compound fertilizers with high nutrient element content are too costly, and organic farmyard manure with long fertilizer efficiency is due to various The reason is that it is difficult to stack and use in rural areas. Therefore, fertilizer sources with long fertilizer efficiency and low cost are urgently needed for agricultural development and grain production.

Abstract

The invention provides a method for producing a long-acting compound fertilizer by utilizing waste resources. The raw materials comprise the following components by weight percent: 48% of yellow phosphorus slag, 32% of waste edible mushroom bag material, 14% of humic acid and 6% of caustic soda. The method comprises the following steps: 1) grinding the yellow phosphorus slag with a ball mill to 200 meshes; 2) grinding the waste edible mushroom bag material to 100 meshes; 3) mixing humic acid and caustic soda, adding clean water of which the addition amount is twice the mixed total amount in the mixture, stirring, heating to 95 DEG C to obtain paste for later use; 4) stirring the materials evenly; 5) placing the mixed materials in a granulating disc to granulate; 6) screening the particles, re-granulating the particles of which the particle size is more than 4.5mm; and 7) drying the particles to obtain the finished product. The method uses the waste resources as raw materials; as the yellow phosphorus slag contains active silica, the photosynthesis and bacteria resistance of the crop can be effectively increased and the nitrogen and phosphorus nutrients can be fully utilized; and as the waste edible mushroom bag material contains rich organic matters and various nutrient elements, the produced compound fertilizer has high fertilizer efficiency, the soil can be improved effectively, the cost is low and the long-acting compound fertilizer provided by the invention is a low-investment long-acting compound fertilizer.
