preparation example Construction

[0036] The present invention provides a method for preparing the selenium nutrient matrix described in the above technical solution, comprising the following steps: mixing selenium nutrient, organic silicon and water to obtain a selenium nutrient solution; soaking wheat grains in the selenium nutrient solution until the wheat grains are blotted dry until the selenium nutrient solution; the wheat grains that have absorbed the selenium nutrient solution are stacked and germinated as the selenium nutrient matrix.

[0037] The invention mixes selenium nutrition, organic silicon and water to obtain selenium nutrition solution. The present invention has no special requirements on the mixing method, and conventional mixing methods in the art can be used.

[0038] After obtaining the selenium nutrient solution, the present invention soaks the wheat grains in the selenium nutrient solution until the wheat grains absorb the selenium nutrient solution. The present invention has no speci...

Embodiment 1

[0047] A kind of selenium nutrition matrix, is made up of the raw material of following quality:

[0048] Main ingredients: 50g of sodium selenite, 10g of organic silicon, 68Kg of water and 100Kg of wheat grains.

[0049] Accessories: 20Kg corn cob, 30Kg rice husk, 10Kg sawdust, 5Kg soybean powder, 1.5Kg calcium carbonate, 1.5Kg calcium sulfate, 1.0Kg potassium dihydrogen phosphate, 0.4Kg magnesium sulfate and 65Kg water.

[0050] Preparation:

[0051] 1) Mix sodium selenite, organic silicon and water to prepare a selenium nutrient solution, then soak the wheat grains with the selenium nutrient solution until it is blotted dry. The water content of the wheat reaches 46wt.%. Germinate and activate in a dark place, and use it when 80% of the wheat germinates.

[0052] 2) Mix the raw materials of the auxiliary materials, dissolve them and mix them with germinated wheat grains, adjust the water content to 63wt.%, and the pH to 7.0.

[0053] 3) Put the above-mentioned mixture in...

Embodiment 2

[0061] A kind of selenium nutrition matrix, is made up of the raw material of following quality:

[0062] Main ingredients: 60g of L-selenium-methylselenocysteine, 10g of organic silicon, 68Kg of water and 100Kg of wheat grains.

[0063] Accessories: 20Kg corn cob, 30Kg rice husk, 10Kg sawdust, 5Kg soybean powder, 1.5Kg calcium carbonate, 1.5Kg calcium sulfate, 1.0Kg potassium dihydrogen phosphate, 0.4Kg magnesium sulfate and 65Kg water.

[0064] The preparation method is the same as in Example 1.

[0065]The method for selenium-enriched cultivation of hickory chick is the same as that of embodiment 1, except that the selenium nutrient matrix of embodiment 2 is used.

[0066] Mycelia collection and sample preparation are the same as in Example 1, and the detection results of the selenium content of mycelia are as follows: No. 1, 30.5 mg / Kg; No. 2, 25.7 mg / Kg; No. 3, 23.4 mg / Kg.

[0067] Morchella field cultivation:

[0068] Liu XX, under the shade of alpine trees in Qingjia...

Abstract

The invention provides a selenium nutrition medium, a preparation method, a morchella selenium-rich culture method and application, and belongs to the technical field of agriculture. The selenium nutrition medium provided by the invention is prepared from the following raw materials in parts by mass: 50 to 60 parts of selenium nutrition, 6 to 15 parts of organic silicon, 68000 parts of water and 1000000 parts of wheat grains. According to the invention, the selenium nutrition is absorbed into the wheat grains under the assistance of permeability of organic silicon, capture failure of other elements in the culture medium on selenium is avoided, the decomposition and utilization rate of morchella hyphae on the wheat grains is high, the absorption and utilization rate of selenium is increased, and the selenium content of morchella products is increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a selenium nutrient substrate, a preparation method, a selenium-enriched culture method of hickory chick and its application. Background technique [0002] Morchella is a rare species of edible fungus, named for its uneven surface and shape like morel. It is a precious edible fungus and medicinal fungus. It is often used for stagnation of Qi due to food accumulation, abdominal fullness, phlegm congestion, adverse Qi, and wheezing and coughing. [0003] Morchella is very nutritious, rich in protein, fat, carbohydrates, etc., and also contains a variety of amino acids, especially glutamic acid. In addition, it has been determined that Morchella contains at least 8 kinds of vitamins: vitamin B1, vitamin B2, vitamin B12, niacin, pantothenic acid, pyridoxine, biotin, folic acid, etc. Moreover, hickory chick contains tumor-inhibiting polysaccharides and antibacterial ...
