Embodiment 1

[0027] A method for cultivating selenium-enriched rice, comprising the following steps:

[0028] (1) Variety selection: choose a hybrid two-line rice variety with moderate maturity, wide adaptability, good disease resistance and stability;

[0029] (2) Seed treatment: choose sunny weather before soaking the seeds, place the seeds in a sunny and dry place to dry for 1 day, soak the sun-dried seeds with 0.5% potassium permanganate solution for 20 minutes, remove and dry them, and place the seeds on Soak in magnetized water at 40°C for 2 hours, remove and place in a magnetic field generator, control the magnetic field strength to 100mT, and process for 6 minutes, then continue to soak in selenium-enriched nutrient solution at a material-to-liquid ratio of 1:3 for 15 hours, then remove with a wet paper towel Wrap for 1 day and set aside;

[0030]The selenium-enriched nutrient solution is prepared as follows: crush 200 parts of selenium-containing rapeseed cake to 20 mesh, add 600...

Abstract

The invention belongs to the technical field of paddy rice cultivation. A cultivation method of selenium-enriched rice comprises the following steps: (1) selecting a variety; (2) treating seeds; (3) sowing the seeds and cultivating seedlings; (4) transplanting the rice seedlings; (5) reasonably applying fertilizer; (6) irrigating. By adopting the cultivation method of the selenium-enriched rice, provided by the invention, the problem that the content of selenium in rice produced by a traditional paddy rice planting method is not enough is solved; inorganic selenium is biologically transformedinto organic selenium, which is easily absorbed by human bodies, through paddy rice and the selenium content of the rice is improved.

Description

technical field [0001] The invention belongs to the technical field of rice cultivation, and in particular relates to a method for cultivating selenium-enriched rice. Background technique [0002] Selenium is one of the essential trace elements for the human body. It is the active center of glutathione peroxidase, which has the functions of eliminating free radicals and anti-aging. In addition, selenium can improve human immunity and has an antagonistic effect on heavy metals. The content of selenium in human tissue is 1 / 10000000, but it determines the existence of life, and its great effect on human health is irreplaceable by other substances. Selenium deficiency will directly lead to the decline of human immunity. Clinical medicine has proved that more than 40 kinds of diseases that threaten human health and life are related to human selenium deficiency, such as cancer, cardiovascular disease, liver disease, cataract, endocrine and metabolic diseases, and pancreatic diseas...
