Selenium-rich and chromium-rich peanut culture formulated fertilizer

Abstract

The invention discloses a selenium-rich and chromium-rich peanut culture formulated fertilizer, prepared from the following raw materials in parts by weight: 400-600 parts of urea, 100-200 parts of ammonium sulfate, 250-300 parts of monoammonium phosphate, 100-150 parts of potassium chloride, 20-50 parts of humic acid, 5-10 parts of compound trace elements, 40-60 parts of bentonite, 1-2 parts of inorganic selenium salt and 0.01-0.05 part of chromium trichloride. An application method of the selenium-rich and chromium-rich peanut culture formulated fertilizer comprises the steps of selecting clay land with a deep soil layer and without fertilizer leakage, and performing basal application in one step by taking brown coal and turf as carriers, and separating seeds from the fertilizer. According to the compound fertilizer and the application method, the advantages of high peanut yield, strong plant disease resistance and suitability for large-area application are achieved, fruited peanut ears are bigger and heavy, and good in quality, and selenium-rich and chromium-rich peanuts contain a selenium element and a trivalent chromium element necessary for human bodies and animals, and are high in nutrition value and beneficial to health.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a formula fertilizer rich in selenium and rich in chromium for peanut cultivation. 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, hypertension, ischemic h...

Problems solved by technology

In the prior art, there are very few studies on selenium-enriched and chromium-enriched peanuts. Most of them are sprayed with selenium- and chromium-containing inorganic salts on the peanut leaves at the early stage of flowering and flowering of peanuts, or soaking peanut seeds with inorganic selenium and chromium solutions. With this method of foliar spraying and seed soaking, it is difficult for selenium and chromium to be fully absorbed, and the effect of enriching selenium and chromium cannot be achieved
