Abstract

The invention relates to a log cultivation method of edible mushrooms rich in selenium and other trace elements. The raw materials of the edible mushrooms rich in selenium and other trace elements not only comprise pines, China firs, cypress trees and other coniferous trees which do not contain bactericidal matters such as rosin, essential oil, alcohol, ether, and the like, but also comprises fagaceae logs, betulaceae logs and other logs on which general deciduous trees can grow, sodium selenite, potassium iodide, copper sulfate, zinc sulfate, ferric sulfate, and the like. The method comprises the steps of log drilling, immersion, inoculation, covering, and the like. The produced edible mushrooms have the advantages of high yield, stable trace element content, simple process and convenient industrial production.

Description

The segment wood cultivated method of rich in selenium and other trace elements edible mushroom

Technical field

The present invention relates to the cultivation method of rich in selenium and other trace elements edible mushroom on Duan Mu

Background technology

Trace element is meant that quantity is few in human body, but has certain physiological function and must be by the element of food intake.The World Health Organization and FAO (Food and Agriculture Organization of the United Nation) have confirmed as in ten in 1997 to essential trace element: copper, cobalt, chromium, iron, fluorine, iodine, manganese, molybdenum, selenium, zinc, wherein zinc, iron, selenium, iodine, copper are five kinds of important trace elements.Trace element is the nutrient that can not synthesize voluntarily in human body, and why ill the people is, and the disease of particularly metabolism aspect all causes owing to the element imbalance.Edible mushroom has the ability of stronger gathering trace element, in the process that edible mushroom is cultivated, add trace element, can promote mycelial growth, improve the edible mushroom quality, make the inorganic microelement of toxic side effect be converted into organic trace element by edible mushroom, help absorption of human body and utilization, accomplish " integration of drinking and medicinal herbs ", " Diet cures more than the doctors " utilizes dietotherapy to reach the dynamic equilibrium of nutrient, to prevent and cure diseases, to have good health and a long life.The edible mushroom micronutrient levels that this method is produced meets state health standards.

Summary of the invention

The rich in selenium and other trace elements culturing edible fungi

1. selection: except that coniferous tree such as the pine that contains bactericidal properties materials such as rosin, essential oil, alcohol, ether, China fir, cypress, the Fagaceae that general broad-leaved can both be grown, the broad-leaved tree of Betulaceae.

2. section wood is prepared: the general grasp of the felling of trees was advisable at 2 the end of month of December to next year, the diameter of a cross-section of a tree trunk 1.3 meters above the ground is 8-12 centimetre, being sawn into the long Duan Mu of 0.2-1.5 rice (deciding on the edible mushroom kind) groined type piles, every turning in 10-15 days once, make Duan Mu have 7-8 to become to do, then Duan Mu is put into tank and add sodium selenite water, make water not have Duan Mu.The content of sodium selenite is that per 100 kg of water add the 0.1-10 gram, soaks and pulls out after 36-48 hour, and excessive moisture is removed in control, when moisture content reaches 50-60%, with diameter is 1.5-2.0 centimetre punching pin punching, and hole depth is that 1.5-2.0 centimetre, pitch-row are 5-7 centimetre, arranges in a triangle.In the hole, insert edible fungus species, cover wooden cover then.

3. play heap and send out bacterium: the section headblock that connects bacterial classification is played liftoff 10-15 centimetre, section wood groined type has been piled plastic covering cloth, and add a cover the straw screen or mat insulation.Every turning in 7-8 days once, Duan Mu is transposed up and down, impel a bacterium even.

4. grand style: play heap after 30 days, mycelia is covered with substantially, the Duan Muyi headrest can be risen, and spacing 7-10 centimetre, can spray water after edible mushroom sprouts.Timely collecting, dry.

Claims (2)

1. Duan Mu is selected in the cultivation of rich in selenium and other trace elements edible mushroom for use, with punching behind sodium selenite or (potassium iodide, copper sulphate, zinc sulphate, iron sulfate etc.) water logging bubble, inserts edible fungus species, has passed through heap then and has sent out bacterium, timely collecting after edible mushroom grows up.

2. described by right one, culturing edible fungus Duan Muwei does not contain deciduous species beyond the coniferous tree such as the pine, China fir, cypress of bactericidal properties materials such as rosin, essential oil, alcohol, ether.Broad-leaved trees such as Fagaceae commonly used, Ulmaceae, Moraceae, Betulaceae.It is 10-12 centimetre that Duan Mu selects the diameter of a cross-section of a tree trunk 1.3 meters above the ground for use, length is 1.5-2.0 centimetre for 0.2-1.5 rice punching diameter, hole depth is 1-2 centimetre, pitch-row is 5-7 centimetre and arranges in a triangle, the sodium selenite of 0.1g-10g/kg, potassium iodide, copper sulphate, zinc sulphate, iron sulfate etc. are put into iron case thin up, add section wood and soaked 36-48 hour, take out the dried excessive moisture of control, making moisture is 50-60%.Sodium selenite, potassium iodide, copper sulphate, zinc sulphate, iron sulfate can use in proportion simultaneously, also can use respectively.The indication edible mushroom is the edible mushroom that can grow on Duan Mu, for example: woodear, Uricularia polytricha, glossy ganoderma, flat mushroom, the yellow mushroom of elm, the brown bacterium of birch, Phellinus, hedgehog hydnum mushroom, mushroom, white fungus, circle mushroom.
