Abstract

The invention discloses a selenium-enriched coating agent. The selenium-enriched coating agent comprises the following components in parts by weight: 0.1 part of a selenium source, 20-60 parts of an adhesive, and 40 parts of water. The invention also discloses selenium-enriched coated corn seeds produced by using the selenium-enriched coating agent and a preparation method of the corn seeds. The selenium-enriched coating agent disclosed by the invention is relatively inexpensive and environmentally friendly, has very high efficiency for biological enhancement of selenium of crops, can effectively prevent seed pests and diseases, greatly reduce a using amount of a selenium fertilizer and improve a utilization rate of the selenium fertilizer; and the selenium-enriched coating agent realizesprecision enhancement, and has lower costs, thereby being very suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of seed coating, in particular to a selenium-enriched coating agent, selenium-coated corn seeds, and a preparation method of the coated corn seeds. Background technique [0002] As one of the three major food crops in my country, the planting area of ​​corn has reached 30 million hectares. It has various uses and plays an important role in animal husbandry and industry. Therefore, corn planting has far-reaching significance and influence on national grain production and national economic development. [0003] In recent years, more and more people pay attention to the trace element selenium. On the one hand, selenium is an essential mineral element for the human body; on the other hand, Chinese residents generally have the problem of insufficient selenium intake. Selenium deficiency will lead to a decline in human immunity, and severe cases will suffer from Keshan disease, arrhythmia, tachycardia or bradycar...
