Small-site organic fertilizer preparation method

Abstract

The invention discloses a small-site organic fertilizer preparation method. The small-site organic fertilizer preparation method mainly includes the steps of (1), mixing animal dung with straw and / or wheat straw uniformly; (2), adding a phosphate fertilizer or powdered rock phosphate into a mixed material obtained from the step (1), and regulating the moisture content of the mixture; (3) adding facultative anaerobes into the mixture and transferring the mixture into a horizontal pulverizer to make all the materials mixed sufficiently; (4), stacking the mixed materials and conducting heat release, oxygenating, turning and fermenting so as to obtain organic fertilizer. The small-site organic fertilizer preparation method is saving in space and applicable to small sites. The organic fertilizer prepared by the method is high in organic matter content, free of stink and capable of decreasing occurrence rate of pest and disease damage after application and improving soil properties.

Description

technical field [0001] The technical field of biological fermentation of the present invention particularly relates to a method for preparing organic fertilizer in a small field. Background technique [0002] In 1937, Soviet microbiologists Krashnikov and Missuskin developed a "nitrogen-fixing bacteria agent", which created a precedent for bacterial fertilizers. Since the 1980s, humans have begun to pay attention to biological fertilizers for the environment and crops. The purpose is to seek environmentally friendly alternatives to chemical fertilizers on the one hand, and to realize waste treatment and resource reuse on the other hand. At present, commonly used fertilizers include inorganic fertilizers and organic fertilizers. Inorganic fertilizers damage the soil. After application, it is easy to lead to a decrease in organic matter content, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and the result is a reduction in water...

Problems solved by technology

At present, the commonly used fertilizers include inorganic fertilizer and organic fertilizer. Inorganic fertilizer damages the soil. After application, it will easily lead to a decrease in organic matter content, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and the result is a reduction in water retention, fertilizer retention and air permeability of the soil.

However, the organic fertilizer preparation process requires space. For small-scale production, the space has become the main factor limiting the production of organic fertilizers.
