Selenium-rich and chromium-rich wheat compound fertilizer and application method

Abstract

The invention discloses selenium-rich and chromium-rich wheat compound fertilizer and an application method. The compound fertilizer is prepared from raw materials in parts by weight as follows: 400-600 parts of compound fertilizer, 100-200 parts of ammonium sulfate, 250-300 parts of manure, 100-150 parts of boron fulvate, 20-50 parts of humic acid, 5-10 parts of compound microelements, 40-60 parts of bagasse, 1-2 parts of inorganic selenium salt and 0.01-0.05 parts of chromium trichloride. The application method of the selenium-rich and chromium-rich wheat compound fertilizer comprises the steps as follows: soil land which has deep soil layers and does not leak fertilizer is selected, lignite and turf are used as carriers, one-time basal application is performed, and seeds and fertilizerare isolated. The compound fertilizer and the application method have the advantages that the wheat yield is high, the disease resistance of plants is high and the compound fertilizer is suitable forlarge-area application. Besides, fruited wheatears are larger, heavy and good in quality, and selenium-rich and chromium-rich wheat contains the selenium and trivalent chromium elements essential to the human body and animals, has high nutrient value and is beneficial to health.

Description

technical field [0001] The invention relates to the field of agricultural technology, 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). It has also been proved that it has a therapeutic effect on children who are malnourished due to lack of protein. 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, hypertensi...

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.
