Embodiment 1

[0032] A method for cultivating selenium-enriched and high-yield rice, comprising the steps of:

[0033] (1) Seed selection

[0034] After spreading the rice seeds, dry them for 1-2 days, and remove the grass seeds, impurities, and diseased grains mixed in the rice seeds; then select the seeds with salt water, pour the seeds into the salt water for rinsing, and remove the floating scorpions. particles, impurities, and then rinse with water 2-3 times.

[0035] (2) Soaking seeds

[0036] Soak the selected seeds in lime water for 8-10 hours, then rinse them with clean water, and then soak them in a circulating water bath with a constant temperature of 37°C for 2-3 days, and set up an ozone generator that releases ozone into the water bath. When it turns white, remove it and drain off excess water;

[0037] (3) Germination

[0038] The soaked seeds were placed in an environment of 25-28°C, and the air humidity was kept at 75%; aeration every 2-4h for 8-10min; ozone treatment f...

Abstract

The invention discloses a cultivation method of selenium-enriched high-yielding rice. The method is characterized by comprising the steps of selecting seeds, soaking the seeds, accelerating germination, sowing, performing field management, performing fertilization management and the like. The steps of soaking the seeds and accelerating germination can improve a germination rate and a survival rate after direct seeding, and reduce the use amount of the seeds; as for selenium-enriching, a rice base fertilizer is prepared by using an unique fermentation process; in the base fertilizer, inorganic selenium is combined with organic selenium in straws, so that selenium is slowly released at a low concentration; rice plants can be promoted to absorb selenium permanently and effectively, the inhibiting effect, on rice growth, caused by excessive concentration of selenium or applying selenium for several times also can be avoided, and therefore the yield of the rice is influenced.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a selenium-enriched and high-yield rice cultivation method. Background technique [0002] Selenium is an essential trace element for the human body. The Chinese Nutrition Society also lists selenium as one of the 15 essential nutrients for the human body. A large number of clinical experiments at home and abroad have shown that selenium deficiency in the human body can cause dysfunction of some important organs, leading to the occurrence of many serious diseases. In selenium-deficient areas, hundreds of millions of people in 22 provinces in China are in selenium-deficient or low-selenium areas, and the population in these areas has a high incidence of tumors, liver diseases, and cardiovascular diseases. [0003] In parts of China's 22 provinces and cities, about 700 million people live in low selenium areas. The content of selenium in food in most areas is below 0.02mg...
