Problems solved by technology

Acidification not only leads to the loss of potassium, calcium, magnesium, molybdenum, boron and other nutrient elements in the soil, resulting in poor crop growth, yield and quality decline, but also causes frequent occurrence of soil-borne diseases, resulting in increased pesticide application, reducing the safety of agricultural products

Abstract

The invention discloses multifunctional carbon-based organic-inorganic compound fertilizer and a preparation method thereof. The compound fertilizer is prepared from the following components in percentage by weight: 5 to 10 percent of urea, 5 to 10 percent of formaldehyde, 25 to 35 percent of mushroom dregs or lotus leaf black charcoal, 20 to 30 percent of calcium magnesium phosphate, 10 to 20 percent of potassium sulfate, 5 to 15 percent of attapulgite and 5 to 15 percent of kaolin; finally, a finished product of granulated multifunctional carbon-based organic-inorganic compound fertilizer isprepared. A compound fertilizer formula disclosed by the invention has the functions of providing nutrients and regulating acidity; the problem of soil degradation brought by an existing fertilizingformula is solved; the multifunctional carbon-based organic-inorganic compound fertilizer has the functions of improving soil, increasing yield and quality of crops and improving the quality of the crops.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a multifunctional carbon-based organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] my country is a big producer of edible fungi, with a total national production of more than 2.57×1.07 million tons, accounting for about 70% of the world’s output; but at the same time, more than 3.68×1.07 million tons of fungal residue waste is produced every year. At present, only a small part of the fungus residue is used as organic fertilizer, and most of them are discarded or burned at will, which seriously pollutes the rural ecological environment. Mushroom residue contains a large amount of nutrients such as organic matter, nitrogen, phosphorus, and potassium, as well as other nutrients such as cellulose, lignin, antibiotics, and mineral elements. How to reuse it has become an important issue facing the edible fungus industry....
