Abstract

The invention provides selenium and chromium rich compound fertilizer for black rice, prepared from the following raw materials in parts by weight: 400-600 parts of nitrogen fertilizer, 800-1000 parts of phosphogypsum, 200-400 parts of potassium fertilizer, 50-100 parts of manganese fertilizer, 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, 1-2 parts of inorganic selenium salt and 0.01-0.03 part of chromium trichloride, wherein the organic trace elements comprise a sucrose complex and a humic acid complex. The selenium and chromium rich compound fertilizer for black rice provided by the invention has the advantages of high yield quantity of black rice, strong disease resistance of plants and adaptability to large-area application, the ears of grains are large and heavy and fine in quality, and the selenium and chromium rich black rice contains selenium and chromium elements essential to human bodies and animals as well as high nutrient value and benefit to health.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-rich and chromium-rich black rice 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 He...

Problems solved by technology

Most of the existing selenium-rich and chromium-rich black rice supplements selenium and chromium elements by spraying the leaves of the black rice or soaking the seeds in the early stage of black rice flowering and flowering. In this way, it is difficult for selenium and chromium to be completely absorbed, and the effect of enriching selenium and chromium cannot be achieved.
