Technical Field
The invention relates to the technical field of fertilizer production, in particular to a special organic fertilizer for selenium-rich vegetables and a preparation method thereof.
Background
Selenium, called as 'fire of life', 'king of cancer' and 'heart guarding spirit' and 'natural antidote', is a trace element essential for human and animals, and has biological properties of scavenging free radicals, resisting oxidation, delaying aging, resisting cancer, enhancing immunity, antagonizing heavy metals, etc. Although the selenium-rich land area in China is large, one problem which always exists in the field of selenium-rich agricultural products is that natural selenium-rich agricultural products cannot be produced by selenium-rich soil, and the content of effective selenium and the form of selenium in the soil are two keys.
At present, with the continuous improvement of living standard of people, people are more urgent to pursue health, and the demand for selenium-rich food is more and more increased. Biological selenium enrichment is an effective way for obtaining organic selenium, and the method for taking selenium-enriched foods such as fruits and vegetables is the most important way for obtaining organic selenium for human bodies. Selenium-rich vegetables are vegetables with high organic selenium content, which are produced by organically introducing selenium into plants in the natural growth stage of the plants through a biotransformation method. Most of the land in China is not rich in selenium, and only a small amount of areas can cultivate selenium-rich vegetables. With the increase of the demand of people on the selenium-rich vegetables, most of the selenium-rich vegetables are obtained by applying selenium fertilizer in the planting process.
However, most selenium fertilizers in the prior art are obtained by adding chemical selenium salt or selenium ore into common fertilizers, the selenium salt or selenium ore is easy to obtain, but has certain toxicity, the soil is polluted due to improper use, the selenium in the selenium ore and selenium salt is not easy to be absorbed and utilized by plants, and the using amount of the fertilizers must be increased for obtaining vegetables with high selenium content, so that the cost is increased, and the problems of excessive fertilization and hardening of the soil are caused.
