Abstract

The present invention relates to an organic ecological controlled-release fertilizer and a preparation process thereof. According to the present invention, the three fertilizer varieties such as the organic fertilizer, the inorganic fertilizer and the microorganism fertilizer are integrally fused by using the multi-stage layering granulation process to form the granular fertilizer, and then the coating agent is used to coat a layer of the natural polymer adhesion film on the particle surface, such that the nutrient release is gradually controlled according to the crop fertilizer requirement rule so as to meet the crop requirement; and the fertilizer is the novel multi-dimensional structure green fertilizer with characteristics of biological phase, biochemical characteristics, plant stability, high efficiency, high quality and no pollution, and further integrates the stable effect of the long-lasting microorganism organic fertilizer of the microorganism compound bacterial fertilizer and the rapid effect and the synergy of the inorganic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of organic chemical industry, and in particular relates to an organic ecological controlled-release fertilizer and a preparation process thereof. Background technique [0002] The existing fertilizer varieties can be divided into three series: one is organic fertilizer, the oldest and most primitive fertilizer, such as pig manure. The second is inorganic fertilizer, which is a kind of chemical fertilizer synthesized by artificial processing with the development of modern science, such as phosphate fertilizer, potash fertilizer, urea, ammonium sulfate, etc. The third is microbial fertilizer. Modern science refers to bioengineering technology, uses organic fertilizer as a culture substrate, and researches and develops various soil microorganisms that are beneficial to plant growth, such as nitrogen-fixing bacteria and rhizobia. Let it be cultivated in a factory to form a product. [0003] With the developmen...
