Method for planting se-enriched rice

Abstract

The invention discloses a method for planting se-enriched rice. The method comprises the following steps of land selection and preparation; seeding; seedling culturing; transplanting; field management: intertillage, weeding, topdressing and insect pest prevention; and harvesting. The selenium content of rice planted by using the method is high, and the yield of the rice is also high. Testing confirms that the yield of the se-enriched rice is 620-650kg per acre, and the selenium content of the rice ranges from 0.1 mg / kg to 0.3mg / kg.

Description

technical field [0001] The invention relates to the field of plant planting, in particular to a method for planting selenium-enriched rice. Background technique [0002] Selenium is an indispensable trace element in the human body. Both selenium and vitamin E are anti-peroxidation substances (peroxides are harmful to the human body), and it has also been proved that it has a therapeutic effect on malnourished children caused by 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, pancreatitis, ...

Problems solved by technology

However, 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. This method of page spraying makes it difficult for all selenium to be absorbed, and the selenium-enriched effect cannot be achieved.
