Selenium-enriched and chromium-enriched taro compound fertilizer

Abstract

The invention provides a selenium-enriched and chromium-enriched taro compound fertilizer. The selenium-enriched and chromium-enriched taro compound fertilizer is prepared from the following raw materials in parts by weight: 400-600 parts of nitrogen fertilizer, 800-1000 parts of potassium fulvic acid, 200-400 parts of coal residue powder, 50-100 parts of bagasse powder, 50-80 parts of silicon fertilizer, 30-40 parts of carbon enzyme, 50-70 parts of nitrohumic acid, 2-8 parts of organic trace elements, 3-7 parts of inorganic trace elements, 10-20 parts of biomass ash residue, 1-2 parts of inorganic selenium salt and 0.01-0.03 part of chromium trichloride. The organic trace elements comprise a saccharose complex and a humic acid complex. The selenium-enriched and chromium-enriched taro compound fertilizer has the advantages of high taro yield, high plant disease resistance and suitability for large-area application; the fruited taros are large and heavy, and are high in quality; the selenium-enriched and chromium-enriched taros contain selenium and chromium essential to human bodies and animals, are high in nutritive value and are beneficial to health.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-rich and chromium-rich taro compound fertilizer. Background technique [0002] Selenium is an indispensable trace element in the human body. Selenium and vitamin E are both anti-peroxidation substances (peroxides are harmful to the human body). Carcinogens are resistant. The main manifestations of selenium deficiency in the human body are hair loss and nail loss. Some patients have skin symptoms, and a small number of patients may have neurological symptoms and tooth damage. People with mild or moderate selenium deficiency have no obvious signs or symptoms. Possible diseases caused by selenium deficiency in human body: energy deficiency malnutrition, hemolytic anemia, Keshan disease, Kashin-Beck disease, hypertension, ischemic heart disease, liver cirrhosis, pancreatitis, fibroid, cancer, fibroid, infertility disease, diabetes, cataract, etc. The World Health O...

Problems solved by technology

Most of the existing selenium-enriched and chromium-enriched taros are supplemented with selenium and chromium elements by spraying taro leaves or soaking seeds in the early stage of taro flowering and flowering. This method of foliar spraying and seed soaking, It is difficult for selenium and chromium to be completely absorbed, and the effect of enriching selenium and chromium cannot be achieved
