Abstract

The invention discloses a multifunctional organic-inorganic insecticide fertilizer and a preparation method thereof. The insecticide fertilizer is prepared from, by weight, 30-40% of camellia oleiferameal, 5-10% of urea, 5-10% of formaldehyde, 15-25% of calcium magnesium phosphate, 10-20% of potassium chloride, 5-15% of attapulgite and 5-15% of kaolin to finally obtain a finished product of the granulated multifunctional organic-inorganic insecticide fertilizer. The multifunctional organic-inorganic insecticide fertilizer has a function of providing nutrients such as organic matters, nitrogen, phosphorus and potassium and further has functions of bacteria killing, heavy metal ion adsorption, acid soil acidity regulation and soil structural improvement.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a multifunctional organic and inorganic medicinal fertilizer and a preparation method thereof. Background technique [0002] Camellia oleifera is a unique woody oil crop in my country. At present, there are about 4 million hectares of camellia oleifera forests in my country, mainly distributed in southern provinces of China. Camellia oleifera meal is the residue left after camellia oleifera oil is pressed, containing protein, oil, tea saponin, crude fiber, sugar, tannin, caffeine and other substances. The output of Camellia oleifera meal is very high in my country. Because Camellia oleifera meal is bitter and poisonous, it cannot be directly used as feed. Therefore, most of the meal is burned or discarded as fuel, and part of it is used as fertilizer after fermentation. The bactericidal effect of tea saponin is one of the main advantages of camellia ...
