Embodiment 1

[0017] The production method of SOD selenium-enriched rice comprises the following steps: soaking seeds, accelerating germination, raising seedlings, and transplanting rice seedlings. Rice seeds of Nanjing 46 were used, and the rice seeds were soaked for 24 hours, removed and drained. According to the SOD activity is 6000u / mg lauric acid modified copper-containing zinc superoxide dismutase lyophilized powder 1g, 0.1g trehalose and the ratio of 200g water configuration superoxide dismutase solution, placed in the sprayer and sprayed before draining Germinate on the rice seeds, put the rice seeds in the seedling field when the germs of the rice seeds are white, and spray again when the seedlings emerge 3 to 5 cm, and spray 7 to 7.5 kg seeds: 200 g superoxide dismutase solution for each spraying .

[0018] After the seedlings cultivated by planting 7-7.5kg seeds per mu of paddy field are transplanted into the paddy field, a bacillus solution with a weight ratio of 45g bacillus: ...

Embodiment 2

[0020] The production method of SOD selenium-enriched rice comprises the following steps: soaking seeds, accelerating germination, raising seedlings, and transplanting rice seedlings. Rice seeds of Nanjing 46 were used, and the rice seeds were soaked for 24 hours, removed and drained. Be the manganese-containing superoxide dismutase freeze-dried powder 1g of the lauric acid modification of SOD activity 3000u / mg, the ratio configuration superoxide dismutase solution of 0.15g mannitol and 100g water, place in the sprayer and spray on the drained Accelerate the germination on the rice seeds, place the rice seeds in the seedling field when the embryos of the rice seeds are white, and spray again when the seedlings emerge 3 to 5 cm, each spraying is carried out with 7 to 7.5 kg of seeds: 100 g of superoxide dismutase solution.

Embodiment 3

[0023] The production method of SOD selenium-enriched rice comprises the following steps: soaking seeds, accelerating germination, raising seedlings, and transplanting rice seedlings. Rice seeds of Nanjing 46 were used, and the rice seeds were soaked for 24 hours, removed and drained. According to the ratio of SOD activity of 8000u / mg lauric acid-modified iron-containing superoxide dismutase freeze-dried powder 1g, 0.1g maltose and 300g water to configure superoxide dismutase solution, place it in the sprayer and spray it on the drained rice Accelerate the germination on the seeds, place the rice seeds in the seedling field when the embryos of the rice seeds are white, and spray again when the seedlings emerge 3 to 5 cm, each spraying is carried out with 7 to 7.5 kg of seeds: 300 g of superoxide dismutase solution.

Abstract

The invention discloses a production method of SOD selenium-enriched rice. The production method comprises the following steps: seed soaking, germination acceleration, seedling cultivation and rice seedling transplanting; during germination acceleration, a superoxide dismutase solution is prepared from water and lauric-acid-modified superoxide dismutase in the weight ratio of (100-300g):1g, and then, the superoxide dismutase solution is sprayed on seeds in a germination acceleration period according to the weight ratio of (100-300g):(7-7.5kg); during seedling cultivation, the superoxide dismutase solution is sprayed on rice seedlings corresponding to the seeds according to the weight ratio of (100-300g):(7-7.5kg); after rice seedling transplanting is finished, a Bacillus solution is prepared from Bacillus and water in the weight ratio of (45-50g):25kg and is mixed with 100ml of liquid selenium fertilizer in a selenate complex form to obtain an SOD selenium-enriched solution, and 20-30kg of SOD selenium-enriched solution is sprayed on leaf surfaces of per mu of rice respectively in a heading period, a flowering period and a filling period. By using the method disclosed by the invention, the problems of high selenium content in plants and low plant yield are solved, the rice is made to be rich in selenium and SOD, and the yield is increased.

Description

technical field [0001] The invention relates to a method for producing rice, in particular to a method for producing SOD selenium-enriched rice, and belongs to the technical field of crop planting and production. Background technique [0002] Superoxide dismutase, or SOD, is an active substance derived from life. SOD can specifically remove harmful free radicals in the body, so as to relieve the damage to the body caused by free radicals oxidizing certain components in the body. Diseases such as oxygen poisoning, acute inflammation, edema, autoimmune diseases, and radiation sickness are all related to the toxicity of reactive oxygen species. Experiments have proved that SOD can scavenge free radicals, so it can eliminate the cause of the above diseases. SOD is the nemesis of free radicals and the scavenger of the human body. Its content in the body is an intuitive indicator of biological aging and death. It has anti-aging, anti-oxidation, anti-radiation, anti-inflammation, ...
