Compound fertilizer for selenium-enriched and chromium-enriched wheat and application method

Abstract

The invention discloses a compound fertilizer for selenium-enriched and chromium-enriched wheat. The compound fertilizer is prepared from the following raw materials in parts by weight: 400 to 600 parts of urea, 100 to 200 parts of ammonium sulfate, 250 to 300 parts of monoammonium phosphate, 100 to 150 parts of potassium chloride, 20 to 50 parts of humic acid, 5 to 10 parts of compound microelements, 40 to 60 parts of bentonite, 1 to 2 parts of inorganic selenium salt and 0.01 to 0.05 part of chromium trichloride. An application method of the compound fertilizer for the selenium-enriched and chromium-enriched wheat, provided by the invention, comprises the following steps: selecting a land with a deep and thick soil layer and without fertilizer leakage; taking lignite and turf as carriers and carrying out basal application in one step; separating seeds from the fertilizer. The compound fertilizer and the application method have the advantages of high wheat yield, high plant disease resistance and applicability to large-area application; fruited wheatears are relatively large and heavy and have good quality; the selenium-enriched and chromium-enriched wheat contains selenium and trivalent chromium elements required by human bodies and animals, is high in nutritional value and is good for health.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a selenium-rich and chromium-rich wheat compound fertilizer and an application method thereof. 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,...

AI Technical Summary

Problems solved by technology

The existing selenium-enriched and chromium-enriched wheat is mostly sprayed with selenium-containing inorganic salt on the wheat leaf surface at the early stage of wheat earing and flowering, or soaking wheat seeds with inorganic chromium solution. This foliar spraying and seed soaking 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.
