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.

Embodiment 1

[0017] 1. Soak the seeds in clean water for 3 hours, remove and air-dry the surface water, then soak the seeds in 1000 times carbendazim solution for 10 hours, turn over every 2 hours for disinfection.

[0018] 2. Take 1000kg of water, 8kg of selenium powder and 0.5kg of sodium nitrophenolate to prepare a selenium-enriched aqueous solution for later use.

[0019] 3. Soak the sterilized seeds in the selenium-enriched aqueous solution, cover the seeds with the solution, soak at a constant temperature of 20°C for 36 hours, and turn it every 2 hours.

[0020] 4. Take out the soaked seeds and drain them, put them in a constant temperature box at 30°C to accelerate germination, and after 3 days, the germination is successful. After the germination, spread the seeds thinly on the indoor ground, and carry out germination for 10 days before transplanting.

[0021] 5. Transplant when the seedlings are 25 days old, transplant 15,000 holes per mu, 2 seedlings per hole, and apply 0.2 kg of...

Embodiment 2

[0028] 1. Soak the seeds in clean water for 4 hours, remove and air-dry the surface water, then soak the seeds in 1000 times carbendazim solution for 12 hours, turn over every 2 hours for disinfection.

[0029] 2. Take 1000kg of water, 10kg of selenium powder and 0.5kg of sodium nitrophenolate to prepare a selenium-enriched aqueous solution for future use.

[0030] 3. Soak the sterilized seeds in the selenium-enriched aqueous solution, cover the seeds with the solution, soak at a constant temperature of 20°C for 48 hours, and turn it every 3 hours.

[0031] 4. Take out the soaked seeds and drain them, put them in a constant temperature box at 30°C to accelerate germination, and after 4 days, the germination is successful. After the germination, spread the seeds thinly on the indoor ground, and smelt them for 7 days before transplanting.

[0032] 5. Transplant when the seedlings are 30 days old, transplant 16,000 holes per mu, 3 seedlings per hole, and apply 0.3 kg of selenium-...

Embodiment 3

[0039] 1. Soak the seeds in clean water for 4 hours, remove and air-dry the surface water, then soak the seeds in 1000 times carbendazim solution for 10 hours, turn over every 2 hours for disinfection.

[0040] 2. Take 1000kg of water, 9kg of selenium powder and 0.5 part of sodium nitrophenolate to prepare a selenium-enriched aqueous solution for later use.

[0041] 3. Soak the sterilized seeds in the selenium-enriched aqueous solution, cover the seeds with the solution, soak at a constant temperature of 20°C for 40 hours, and turn it every 3 hours.

[0042] 4. Take out the soaked seeds and drain them, put them in a 30°C incubator to accelerate germination, and after 4 days, the germination is successful. After the germination, spread the seeds thinly on the indoor ground, and carry out germination for 8 days before transplanting.

[0043] 5. Transplant when the seedlings are 28 days old, transplant 15,000 holes per mu, 3 seedlings per hole, and apply 0.3 kg of selenium-enrich...

Abstract

The invention relates to a selenium-rich rice growing method. The method comprises the steps of 1, seed breeding; 2, plant transplanting; 3, field management; 4, crop harvesting. By the rice growing method, selenium-rich cultivation is initiated at the time of seed soaking and plant transplanting, so that the riping of rice is supplemented with selenium elements from the origin; at the same time reinforced selenium supplementation is conducted once before the crop harvesting, the selenium content of the rice at post-harvest time is effectively increased, and the selenium content of the polished rice further reaches the standard of selenium nationwide. The selenium-rich rice growing method is higher in utilization rate, in comparison to the methods of foliage dressing or selenium-rich cultivation through substrate, the replenishment of the mineral selenium is made a fact of the planted selenium-rich polished rice by the daily meals consumed by people, and the method addressing the selenium deficiency trouble of people is of great significance.

Description

technical field [0001] The invention relates to the field of planting, in particular to a method for planting selenium-enriched rice. Background technique [0002] Selenium is honored as "the tinder of life" by domestic and foreign medical and nutritional circles. The content of selenium in human tissue is one ten millionth, but it determines the existence of life. Its great effect on human health cannot be replaced by other substances of. 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. [0003] Rice is the staple food of our country, and the level of its selenium content is closely related to the nutritional status of human selenium. Rice is easy to store, can be sold for a long time, and consumers can also eat organic...
