Abstract

The invention discloses a soil improvement type selenium-enriched slow release fertilizer special for vegetables. The slow release fertilizer is prepared from urea, urea phosphate, ammonium chloride, potassium chloride, diammonium phosphate, potassium nitrate, calcium humate, magnesium humate, boric acid, ammonium molybdate, zinc carbonate, sodium humate, manganese chloride, citric acid, a slow release agent and a selenium-enriched additive. The invention further provides a preparation method of the soil improvement type selenium-enriched slow release fertilizer special for the vegetables. By conducting slow release agent enveloping, the release efficiency and quality of fertilizer nutrients are improved, the vegetable yield is increased, the vegetable quality is improved, and the added selenium-enriched additive can provide rich selenium elements for growth of the vegetables, so that the quality of the vegetables is improved.

Description

technical field [0001] The invention relates to a slow-release fertilizer, in particular to a soil-improving type slow-release fertilizer special for selenium-enriched vegetables and a preparation method thereof. Background technique [0002] Selenium is an essential life element for the human body, and has been designated by the World Health Organization and the Chinese Medical Association as the third largest micronutrient health care element after iodine and zinc. Selenium is a component of human and animal glutathione peroxidase and a prosthetic group of the active site of the enzyme family. Selenium can participate in various metabolic processes of human tissues. Every important organ needs a certain amount of selenium to maintain normal functions. The human body has many functions such as anti-oxidation, preventing cancer, detoxification, enhancing human physical strength, and improving immunity. [0003] Vegetables in the prior art have single nutrients, low yield, a...
