Embodiment 1

[0019] A method for cultivating selenium-enriched wheat, the method is carried out as follows:

[0020] A, fertilizer making: take sugar beet pulp as main raw material, get sugar beet pulp 35kg, add sodium selenite 0.5kg, ammonium sulfate 2kg, lactic acid bacteria fermentation product 0.05kg, make fermented fertilizer after conventional mode fermentation;

[0021] B, fertilization: before wheat is planted, apply 10 kilograms of fertilizers that step a obtains per acre of wheat field according to conventional fertilization method;

[0022] C, be 1: 1: 1 sodium selenite, ammonium sulfate, potassium dihydrogen phosphate mix by weight, stir evenly, be prepared as the foliage fertilizer that concentration is 0.05% after adding water;

[0023] d. Spraying at the jointing stage, initial stage and mid-stage of grain filling of wheat, and after the wheat is mature and harvested, it will be a finished wheat product rich in selenium.

[0024] At this time, the common 2,3-aminonaphthalen...

Embodiment 2

[0026] A method for cultivating selenium-enriched wheat, the method is carried out as follows:

[0027] a. Manure making: use beet pulp as the main raw material, adjust its water content to 65%, take 38kg of beet pulp, add 0.7kg of sodium selenite, 2kg of ammonium sulfate, 0.08kg of lactic acid bacteria fermentation, and then use plastic film or airtight Cover it tightly to isolate the air, press heavy objects on it to make it in close contact, and remove the air. After 15 days of anaerobic fermentation, this selenium-enriched fermented fertilizer is obtained.

[0028] B, fertilization: before wheat planting, apply 10 kilograms of fertilizers obtained in step a per acre of wheat; and bury the selenium-enriched fertilizer deeply 20cm below the ground surface;

[0029] C, be 1: 1: 1 sodium selenite, ammonium sulfate, potassium dihydrogen phosphate mix by weight, stir evenly, be prepared as the foliage fertilizer that concentration is 0.05% after adding water;

[0030] d. Sprayi...

Embodiment 3

[0033] A method for cultivating selenium-enriched wheat, the method is carried out as follows:

[0034] a. Manure making: use beet pulp as the main raw material, adjust its water content to 68%, take 35kg of beet pulp, add 1kg of sodium selenite, 3kg of ammonium sulfate, 0.06kg of lactic acid bacteria fermentation, and then use plastic film or airtight The material is tightly covered to isolate the air, and a heavy object is pressed on it to make it closely contact, and the air is excluded. After 20 days of anaerobic fermentation, this selenium-enriched fermented fertilizer is obtained.

[0035] B, fertilization: before wheat planting, apply 13 kilograms of fertilizers obtained in step a per acre of wheat; and bury the selenium-enriched fertilizer 25 cm below the ground surface;

[0036] c, mix sodium selenite, ammonium sulfate, potassium dihydrogen phosphate, boric acid, and zinc sulfate in a weight ratio of 1:1:1:1:1, stir evenly, and prepare a 0.1% leaf surface after adding...

Abstract

The invention relates to a breeding method of a selenium rich crop, in particular to a breeding method of selenium rich wheat; the method comprises the following steps: bagasse is taken as major raw material, and added with sodium selenite, ammonium sulfate and lactobacillus fermented substance, the proportion by weight of the added raw materials is as follows: 35-50 parts of bagasse, 0.5-2 parts of sodium selenite, 2-5 parts of ammonium sulfate and 0.05-0.1 part of lactobacillus fermented substance; the selenium rich fermented fertilizer is produced by a fermentation method; before planting wheat, 10-20kg of fertilizer obtained from step a is fertilized on each mu of wheat field; the sodium selenite, the ammonium sulfate and potassium dihydrogen phosphate are mixed according to a weight ratio of 1:1:1, evenly stirred and added with water to be made into a foliar fertilizer with concentration of 0.05-0.2%; the foliar fertilizer is sprayed in the shooting stage, early grain filling stage and middle grain filling stage of wheat; after the wheat is ripe and harvested, the selenium rich wheat product is obtained. The breeding method solves the problem that the former selenium rich products are not ideal enough in selenium content, and increases the content of selenium in the wheat.

Description

Technical field: [0001] The invention relates to a method for cultivating selenium-enriched crops, in particular to a method for cultivating selenium-enriched wheat. Background technique: [0002] Selenium is an essential trace element for humans. Selenium participates in the formation of glutathione peroxidase (GSH-Ps) in the form of selenocysteine ​​(SeCys) in the human body, thereby removing excessive active oxygen in the body free radicals. Selenium is used by middle-aged and elderly people for anti-aging; anyone can take it to prevent cancer and detoxify, prevent cardiovascular disease, and maintain the normal operation of the heart. It has the functions of anti-oxidation and improving immunity. However, 72% of my country's regions are in selenium-deficient and low-selenium belts, and it is difficult to obtain enough trace element selenium necessary for the human body only from agricultural products that naturally contain organic selenium. The lack of selenium intake i...
