preparation example Construction

[0025] The preparation method of the organic selenium-enriched compound liquid described in the embodiment of the present invention comprises the following steps: take 95 kg of pure water, put 3.5 kg of culture medium, 1 kg of strain, and 100 g of selenium source into a container, shake and fuse at 25-30°C, After that, shake for 10 minutes every 6 hours, and the finished product of the organic selenium-enriched compound liquid can be obtained in 7 to 8 days, and the color of the finished product is orange-red.

[0026] Wherein, the preparation method of the medium used in the organic selenium-enriched compound solution is as follows:

[0027] 1) Prepare enrichment medium:

[0028] To 10 L of distilled water with a pH value of 7.0, add NH 4 Cl: 100.00g; NaHCO 3 : 10.00g; KH 2 PO 4 : 2.00g; CH 3 COONa: 25.00g; MgSO 4 ·7H 2 O: 2.00g; NaCl: 10.00g; three growth factors: 100ml; trace element solution 100ml to obtain the enrichment medium;

[0029] 2) Prepare growth medium N...

Embodiment 1

[0036] Take the organic selenium-enriched compound solution and mix it with clear water at a mass volume ratio of 1:50 to obtain an organic selenium-enriched compound solution. Spray the organic selenium-enriched compound solution once each at the tillering stage, booting stage, and pre-filling stage during the growth and cultivation of rice. solution, all the other are the same as the conventional planting method of rice. After the harvest, the selenium content in every kilogram of selenium-enriched rice is 200 μg, and the rice yield per mu is 1240 jin.

Embodiment 2

[0038] Take the organic selenium-enriched compound solution and mix it with clear water at a mass volume ratio of 1:50 to obtain an organic selenium-enriched compound solution. Spray the organic selenium-enriched compound solution once each at the tillering stage, booting stage, and pre-filling stage during the growth and cultivation of rice. solution, all the other are the same as the conventional planting method of rice. After the harvest, the selenium content in every kilogram of selenium-enriched rice is 205 μg, and the rice output per mu is 1230 jin.

Abstract

The invention relates to a planting method of selenium-rich rice. The selenium-rich rice is planted according to a breeding method of normal rice. The planting method further comprises the following steps: taking an organic selenium-rich composite liquid, mixing the organic selenium-rich composite liquid with clean water in the mass volume ratio of 1: 50 so as to obtain an organic selenium-rich composite solution, and spraying the organic selenium-rich composite solution once at the tillering stage, the booting stage and the early stage of grouting in the process of growing and breeding the rice, wherein the content of organic selenium in each liter of the organic selenium-rich composite liquid is 200-240 mg. In the process of planting the rice, after the diluted organic selenium-rich composite liquid is sprayed, the yield of each mu of rice can reach more than 1200 jin, and the content of selenium in each kilo of rice is greater than or equal to 200 micrograms and is increased by more than 10 times compared with common rice.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a method for planting selenium-enriched rice. Background technique [0002] Selenium is a chemical element with the chemical symbol Se. It is a nutrient element beneficial to plants and an essential trace element for the human body. Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. Selenium, vitamin E, allicin, linoleic acid, germanium, zinc and other nutrients have synergistic antioxidant effects and increase antioxidant activity. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals. [0003] Selenium deficiency in the human b...
