Problems solved by technology

But, the output of existing Dictyophora cultivation method is still far from satisfactory
At the same time, the fruiting bodies of Dictyophora have a certain enrichment effect on selenium, but the selenium content of Dictyophora that grows naturally in nature is unstable.
At present, artificial selenium-enriched cultivation of Dictyophora is still rarely carried out. The existing selenium-enriched cultivation techniques of Dictyophora mainly use special selenium-enriched substrate materials or apply special fertilizers for inorganic selenium supplements when sowing. These methods are limited to Dictyophora mycelium The selenium source is applied during the growth stage, and the selenium content of the fruiting body varies with the different production stages (that is, different tides), resulting in the instability of the total selenium content of Dictyophora

Embodiment 1

[0041] Embodiment 1 A kind of selenium-enriched bamboo fungus cultivation soil

[0042]Take clean and non-polluting vermicompost and miscellaneous wood chips at a volume ratio of 1:1, add organic selenium source aqueous solution, mix well to form a selenium-containing substrate with a moisture content of about 60%, and stack and ferment the selenium-containing substrate for 12 days. keep its water content about 60%, and the pH value is about 6.5, and make the selenium-containing organic matter whose fresh base selenium content is 3mg / kg;

[0043] Take the clean yellow heart soil, air-dry, smash, sieve and purify, remove impurities and soil clods with a diameter greater than 3cm, and mix the selenium-containing organic matter with the purified yellow heart soil evenly at a volume ratio of 1:1 to obtain clean selenium-enriched bamboo fungus cultivation soil ( Such as figure 1 shown). The prepared selenium-enriched bamboo fungus cultivation soil is suitable for use in the selen...

Embodiment 2

[0045] Take clean and non-polluting vermicompost and miscellaneous wood chips at a volume ratio of 1:1, add organic selenium source aqueous solution, mix well to form a selenium-containing substrate with a moisture content of about 60%, and stack and ferment the selenium-containing substrate for 10 days. keep its water content about 60%, and the pH value is about 6.5, and make the selenium-containing organic matter whose fresh base selenium content is 3mg / kg;

[0046] The clean yellow heart soil was air-dried, crushed, sieved and purified to remove impurities and soil clods with a diameter greater than 3 cm, and the selenium-containing organic matter was mixed with the purified yellow heart soil evenly at a volume ratio of 1:2 to obtain clean selenium-enriched bamboo fungus cultivation soil. The prepared selenium-enriched bamboo fungus cultivation soil is suitable for use in the selenium-enriched cultivation of bamboo fungus. It contains organic matter and organic selenium, is ...

Embodiment 3

[0048] Take clean and non-polluting vermicompost and miscellaneous wood chips at a volume ratio of 1:1, add organic selenium source aqueous solution, mix well to form a selenium-containing substrate with a moisture content of about 60%, and stack and ferment the selenium-containing substrate for 15 days. keep its water content about 60%, and the pH value is about 6.5, and make the selenium-containing organic matter whose fresh base selenium content is 3mg / kg;

[0049] The clean yellow heart soil was air-dried, crushed, sieved and purified to remove impurities and soil clods with a diameter larger than 3 cm, and the selenium-containing organic matter was mixed with the purified yellow heart soil evenly at a volume ratio of 2:1 to obtain clean selenium-enriched bamboo fungus cultivation soil. The prepared selenium-enriched bamboo fungus cultivation soil is suitable for use in the selenium-enriched cultivation of bamboo fungus. It contains organic matter and organic selenium, is r...

Abstract

The invention relates to selenium-rich cultivation soil and application thereof. The selenium-rich cultivation soil comprises selenium-containing organic matter and soil. The selenium-containing organic matter is prepared from raw materials including wormcast, sawdust and a selenium source. When the selenium-rich cultivation soil is used for dictyophora cultivation, the yield and the selenium content of dictyophora can be remarkably improved.

Description

technical field [0001] The invention relates to planting technology, in particular to selenium-enriched cultivation soil and its application. Background technique [0002] Selenium (Se) is a high-efficiency antioxidant in the human body and an essential trace element for the human body. It has various biological functions such as improving the body's immunity, anti-tumor, and anti-aging. The patron saint of the human body", "natural antidote", and the Chinese Nutrition Society also lists selenium as one of the 15 essential nutrients for the human body. There are nearly 50 countries and regions in the world with selenium deficiency problems. With the continuous improvement of people's requirements for healthy food, the development of selenium-enriched edible mushroom products has become a new hot spot in research and development. [0003] Dictyophora Desv, also known as bamboo fungus and bamboo ginseng, has a dark green cap, a snow-white cylindrical stipe, a pink or brown eg...
