preparation example Construction

[0027] 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.

[0028] Wherein, the preparation method of the medium used in the organic selenium-enriched compound solution is as follows:

[0029] 1) Prepare enrichment medium:

[0030] 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;

[0031] 2) Prepare growth medium N...

Embodiment 1

[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 in the early stage of baby cabbage growth, and spray the organic selenium-enriched compound solution once 10 days before baby cabbage is harvested The compound solution, after harvesting, contains 145 μg of selenium per kilogram of selenium-enriched baby cabbage, and the yield of baby cabbage per mu increases by 15%.

Embodiment 2

[0040] Take the organic selenium-enriched compound solution and mix it with 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 in the early stage of mustard growth, and spray the organic selenium-enriched compound solution once 15 days before mustard harvest , after harvest, the selenium content per kilogram of selenium-enriched mustard is 155μg, and the yield per mu of mustard is increased by 17%.

Abstract

The invention provides a planting method of selenium-rich leafy vegetables. The selenium-rich leafy vegetables are planted according to the planting method of normal leafy vegetables. 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, spraying the organic selenium-rich composite solution once at the early stage of the growth of the leafy vegetable, and spraying the organic selenium-rich composite solution once 10-15 days before harvesting the leafy vegetables, wherein the content of organic selenium in each liter of the organic selenium-rich composite liquid is 200-240 mg. After the diluted organic selenium-rich composite liquid is sprayed, the yield of each mu of leafy vegetables can be increased by about 15%, and the content of selenium in each kilo of selenium-rich leafy vegetables is 145-155 micrograms and is increased by more than 10 times compared with common leafy vegetables.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a method for planting selenium-enriched leafy vegetables. 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...
