Abstract

The present invention provides slowly released organic and inorganic fertilizer, and belongs to the field of agricultural production technology. It consists of mainly slowly released organic mud fertilizer comprising pond sludge and clay, slowly released organic fertilizer powder, slowly released organic coating agent, slowly released organic bone-shell powder, anti-caking agent, nitrogen fertilizer, phosphate fertilizer and potash fertilizer. It is granular fertilizer produced through mixing, adsorption and coating. The nitrogen fertilizer, phosphate fertilizer and potash fertilizer are coated for slowly releasing. The fertilizer has raised utilization and soil improving effect.

Description

Technical field: [0001] The invention relates to a slow-release organic powder and slow-release organic and inorganic fertilizers, belonging to the field of agricultural production materials. Background technique: [0002] With the change of modern agricultural production methods, in order to greatly increase the yield, people's habitual practice is to rely on the application of a large amount of chemical fertilizers, and it has indeed been proved that the yield per acre of crops can be greatly increased. But now when people apply chemical fertilizers in the field, they generally adopt the methods of spreading, hole application and strip application, and the chemical fertilizers are directly applied to the farmland. However, the utilization rate of chemical fertilizers directly applied to farmland is low, and most of the fertilizers are consumed due to volatilization, penetration and loss. For example, the utilization rate of nitrogen fertilizer is about 33%, the utilizatio...
