Embodiment Construction

[0006] The environment-friendly organic ecological controlled-release fertilizer of the present invention includes organic fertilizer and inorganic fertilizer. It is composed of three kinds of fertilizers: microbial fertilizer, organic fertilizer and inorganic fertilizer. According to weight percentage, the composition of each component is as follows: microbial fertilizer 10%, Organic fertilizer 20%, inorganic fertilizer 70%.

[0007] The said microbial fertilizer is composed of nitrogen-fixing bacteria, phosphate-dissolving bacteria, potassium-dissolving bacteria and rhizobia. According to weight percentages, the composition of each component is as follows: nitrogen-fixing bacteria 40%, phosphate-dissolving bacteria 15%, potassium-dissolving bacteria 25%, root nodules Bacteria 20%.

[0008] Organic fertilizer: After factory production, commercial organic fertilizer that does not contain microorganisms with specific fertilizer effects, to provide organic matter and a small amount o...

Abstract

The invention relates to an organic ecological controlled-release fertilizer and a preparation process thereof. According to the method, three series of varieties of fertilizers, such as organic fertilizers, inorganic fertilizers and microbial fertilizers are fused together by adopting a multi-stage layered granulation process to form granules, and then the surfaces of the granules are coated witha layer of natural polymer colloidal film by utilizing a coating agent, so that the purposes of gradually controlling the release of nutrients and providing the nutrients for crops according to the fertilizer requirement rule of the crops are achieved. The fertilizer is an efficient high-quality pollution-free green fertilizer with a novel multi-dimensional structure, biochemical characteristicsof a biological phase system and plant stability characteristics. The fertilizer integrates the long-acting effect of a microbial composite bacterial fertilizer, the stable effect of a microbial organic fertilizer and the quick effect and synergism of the inorganic fertilizer.

Description

Technical field [0001] The invention belongs to the technical field of organic chemical engineering, and specifically 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. The development of modern science, artificial processing, synthetic chemical fertilizer, such as phosphate fertilizer, potash fertilizer, urea, ammonium sulfate and so on. The third is microbial fertilizer. Modern science refers to bioengineering technology and uses organic fertilizer as a culture medium to research and develop various soil microorganisms useful for plant growth, such as nitrogen-fixing bacteria and rhizobia. Let it be cultivated as a factory to form a product. [0003] With the development of science, research on crop fertilizati...
