Abstract

The invention discloses an efficient multifunctional selenium-rich fertilizer and a production process thereof and relates to the technical field of functional fertilizers. The process comprises the steps of taking a 3% chitosan coated compound fertilizer, a 4% chitosan coated compound fertilizer, a 5% chitosan coated compound fertilizer, sulphur coated urea, potassium sulfate, diammonium phosphate, sodium selenite, zinc sulfate and borax as raw materials, mixing materials according to the specified mixture ratio, and obtaining a finished product after stirring uniformly through a mixer, metering and packing. The efficient multifunctional selenium-rich fertilizer is reasonable in nutrient mixture ratio, high in use ratio and significant in effect of production increase of crops and quality improvement.

Description

technical field [0001] The invention relates to the technical field of functional fertilizers, in particular to an efficient and multifunctional selenium-enriched fertilizer. Background technique [0002] At present, some emerging technologies such as biotechnology, polymer material technology, and industrial biotechnology are being widely used in the field of fertilizer research and development and production, promoting the transformation and upgrading of my country's fertilizer industry. my country's traditional fertilizer products focus on the development of nutrient functions, but the application of fertilizers with a single nutrient function is difficult to overcome a series of problems such as soil continuous cropping obstacles, low water production efficiency, and environmental pollution under the current intensive agricultural conditions. [0003] Therefore, the development of fertilizers with additional functions in addition to nutritional functions has become an ...
