Problems solved by technology

Due to the coexistence of a large amount of heavy metal ions and selenium ions in the soil, there is a competitive relationship between the absorption of selenium ions in rice, which affects the absorption of selenium ions, and the absorption of heavy metal ions also affects the quality of rice.

Abstract

The invention discloses a planting method of selenium-enriched organic rice. The method comprises the steps of 1, field management, wherein a heavy metal adsorbing material with a thickness of 5-10 cm is laid after rice field soil is deeply plowed by 55-70 cm, then soil refilling is carried out, next, underground water is poured to soak the rice field for 20-30 days, again, the soil is exposed under the sun for 3-5 days after the water is drained, the heavy metal adsorbing material is taken out, and finally, an inorganic fertilizer with a thickness of 2-4 cm is buried at the 10-15 cm position of the soil; 2, transplanting management; 3, fertilization management, wherein firstly an active material is sprayed 1-3 hours before a selenium-rich leaf force fertilizer is sprayed, and the spraying quantity of the active material is 10-20 kg / mu. The selenium-rich organic rice planted through the planting method is fine and long in granule, crystal, transparent, soft and non-stick, the content of organic selenium is high, the incidence of diseases and insect pests is low, the content of heavy metal is low, and the selenium-rich organic rice has market competitiveness.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of rice planting, in particular to a method for planting selenium-enriched organic rice. [0003] 【Background technique】 [0004] Selenium is an indispensable trace element to maintain the normal functions of the human body. Selenium deficiency in the human body can lead to various diseases. Modern scientific research has proved that selenium has the functions of anti-oxidation, enhancing human immunity, effectively removing harmful waste from the human body, promoting human health, and delaying aging. Usually, the normal intake of selenium per person per day should not be less than 50 micrograms, and the selenium content of ordinary rice is extremely low, which cannot meet the normal needs of the human body. my country's "Journal of Nutrition" once reported that 72% of the country's regions belong to selenium-deficient or low-selenium regions, and more than 2 / 3 of the population have insufficient selenium in...
