Problems solved by technology

However, sodium selenate is a highly toxic chemical, which can easily cause great harm to the health of operators during production
At the same time, the residual sodium selenate that has not been absorbed by plants will pose a great threat to the health of consumers
On the other hand, in the existing selenium-enriched fertilizers, except for the high content of selenium element, the remaining nutrient content is relatively small, and the function is relatively single. The single use of this type of selenium-enriched fertilizer will have a great impact on the yield and quality of agricultural products.

Abstract

The invention discloses a selenium-enriched organic fertilizer and a preparation method and application thereof, and belongs to the field of organic fertilizers. Raw materials include, by weight parts, 85-95 parts of chicken manure, 4-5 parts of animal meat powder, 10-15 parts of attapulgite, 1-3 parts of selenium-enriched egg and 2-4 parts of EM strains. The raw materials are easy to collect, thehumification degree is improved with the fermented chicken manure as the main raw material, and the physical properties of the soil are improved due to no root or seedling burning occurs, and the obtained selenium-enriched organic fertilizer has a sustained release effect and ion exchange capacity. The loss of nutrients is reduced, the fertilizer efficiency is improved, and the dry quality of agricultural products is improved. The preparation method is simple in process, low in cost and wide in application range.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and in particular relates to a selenium-enriched organic fertilizer, a preparation method and an application. Background technique [0002] Selenium is an indispensable trace element in the human body. It has anti-cancer and anti-oxidation effects, can antagonize harmful metals, can regulate the absorption and utilization of vitamin A, vitamin C, vitamin E, and vitamin K, and can regulate protein synthesis. There are no organs that store selenium for a long time in the body. The selenium needed by the collective should be continuously obtained from the diet in sufficient amounts. The balance of selenium concentration plays an important role in protecting and promoting the physiological functions of many organs and tissues. [0003] There are many ways to supplement selenium, but practice has proved that medicine supplement is not as good as food supplement. By applying selenium-enriched organi...
