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.

Abstract

The invention discloses a planting method of selenium-rich paddy, which comprises the steps of applying compound fertilizer to the paddy at a pustulation period of the paddy, wherein the application amount of the compound fertilizer for each acre is 40 to 45kg, watering treatment is immediately carried out after each time of fertilizer application, the compound fertilizer is prepared from the following materials: selenium-rich fertilizer, a sodium nitroprusside solution, calcium chloride, multi-vitamin, compound amino acid and filler. According to the planting method provided by the invention,specific cultivation management is carried out on the paddy, during the period, topdressing is carried out by adopting the compound fertilizer prepared by multiple raw material ingredients, the selenium content of the paddy is effectively improved, meanwhile, the yield, taste, nutritive value and the like of the paddy are also improved, and the planting benefit is remarkably increased; the planting method has extremely high popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a method for planting selenium-enriched rice. 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, cataract, etc. The World Health O...
