Problems solved by technology

The slow-release chemical fertilizers have the following advantages: 1) reduce nutrient loss and increase the utilization rate of chemical fertilizers, 2) reduce the chemical and biological fixation in the soil that causes plants to be unusable, 3) reduce the denitrification and nitrogen nitrification caused by However, the existing slow-release chemical fertilizers have the following problems: 1) The film-forming materials of the coating layer are mostly synthetic polymers, which are not easy to biodegrade; 2) Direct use of pure starch or various plant straw powders plus chemical adhesives Mixture coating, short release period or difficult to control the release rate; 3) The coating materials used are expensive, such as coupling agents such as silane, titanate or aluminate, and the high cost is not conducive to large-scale application
Above two kinds of prior art, all have the shortcoming that preparation method is complicated, and raw material cost is higher, are not suitable for large-scale production

Abstract

The invention provides environment-friendly organic slow-release fertilizer and a preparation method thereof. The environment-friendly organic slow-release fertilizer is prepared from the following components: diatomite, an excrement fermented matter, composted fertilizer, an EM compound bacterium agent, a biological enzyme, chestnut shell powder, plant starch, zeolite powder, calcium superphosphate, potassium chloride, a natural polymer, calcium lignosulphonate, a microelement and water. The slow-release fertilizer prepared by the method has a relatively long release period and no pollution to soil; a preparation technology is simple and convenient to operate and a technological process has a short period; wastes are not generated so that the environment-friendly organic slow-release fertilizer meets an economical, green and environment-friendly concept and industrialized popularization and application are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an environment-friendly organic slow-release fertilizer and a preparation method thereof. Background technique [0002] Chemical fertilizers play a pivotal role in agricultural production. The demand for chemical fertilizers in agricultural production is very high. However, due to the nature of chemical fertilizers and the requirements for the soil environment, the physical properties of the soil continue to deteriorate, which not only affects the improvement of crops, but also causes huge pollution to the environment; therefore, Improving the utilization rate of chemical fertilizers, reducing excessive fertilization, and avoiding environmental pollution have become urgent problems to be solved in the development of sustainable agriculture. Slow-release fertilizers came into being. [0003] Continued overuse of chemical fertilizers has led to widesp...
