Problems solved by technology

Most of the existing selenium-enriched rice is sprayed with selenium-containing inorganic salt on the rice leaf surface at the early stage of rice flowering and flowering. In this way of foliar spraying, it is difficult for all selenium elements to be absorbed, and the selenium-enriched effect cannot be achieved.

Abstract

The present invention provides a selenium-rich rice compound fertilizer. The compound fertilizer comprises the following raw materials in parts by weight: 400-600 parts of a nitrogen-phosphorus-potassium fertilizer, 50-70 parts of nitro humic acid, 2-8 parts of organic trace elements, 3-7 parts of inorganic trace elements, 10-20 parts of biomass slag, and 1-2 parts of inorganic selenium salt. The organic trace elements comprise a sucrose sugar complex and a humic acid complex. The selenium-rich rice compound fertilizer provided by the present invention has the advantages that the selenium-rich rice compound fertilizer is high in rice yield, high in plant disease resistance and suitable to be applied in large area; rice ears are relatively large and heavy; and because selenium-rich rice contains selenium that is essential for human bodies and animals, the selenium-rich rice is high in nutritional value and beneficial for health.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a selenium-enriched 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). 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 heart disease, liver cirrhosis, panc...
