specific Embodiment

[0008] Below is a kind of specific embodiment of the present invention: the formula of the compost used as the main raw material of rice straw or Cassia rotundum and cottonseed hulls used in the present invention is (taking the preparation of 100kg dry compost as example, and should select the low cadmium content as far as possible Raw materials): 41kg of straw or Cassia round leaves, etc., 36kg of cottonseed hulls, 11kg of cow dung, 9kg of wheat husks, CaCO 3 1.1kg, CaSO 4 1.1 kg, 0.8 kg of white sugar, adding 5.7 grams of sodium selenite and 5.7 grams of lanthanum chloride to form a selenium-lanthanum pollution reducer composition as a decontamination aid.

[0009] The concrete processing step of the present invention indoor cultivation is as follows:

[0010] One is to choose culture materials and mushroom houses. Prepare auxiliary materials according to the above formula and select fresh straw, cottonseed hulls, and cow dung to dry and store for later use. The mushroo...

Abstract

The invention provides a cultivation method for high-quality agaricus blazei by using selenium and lanthanum as a dirt reducing agent. Raw materials and auxiliary materials commonly used for the cultivation of the existing agaricus blazei are adopted as cultivation materials. The method comprises the following steps: selecting fresh raw materials and drying the raw materials for standby; selecting a mushroom house or a cultivation room; uniformly mixing the raw materials and the auxiliary materials; sterilizing and packaging the raw materials and the auxiliary materials in bags; sterilizing and inoculating the materials; transferring the bags to a bed in the cultivation room for cultivation; and managing the bags as well as picking and harvesting the agaricus blazei before and after the fruiting. The method is characterized in that a selenium-lanthanum dirt reducing agent composition containing the selenium and the lanthanum (rare earth element) is added in every 100kg of dry cultivation materials as a dirt removing auxiliary agent, and the selenium-lanthanum dirt reducing agent composition consists of 4-10g of sodium selenite and 3-10g of lanthanum chloride. In the invention, the content of various heavy metals in agaricus blazei fruiting bodies can be reduced, wherein the content of cadmium is reduced to less than 5mg / kg; and the content of beneficial elements is also increased; therefore, the nutritional quality of the agaricus blazei can be obviously improved.

Description

(1) Technical field [0001] The invention relates to a cultivation technology of edible fungi, specifically a method for cultivating high-quality Agaricus blazei using selenium and lanthanum as a pollution reducing agent (also known as a decontamination aid) (that is, a method for cultivating high-quality Agaricus blazei selenium lanthanum pollution reducer or decontamination aid). (two), background technology [0002] Agaricus blazei (also known as Brazil mushroom) has higher nutritional value and medicinal value than most other mushrooms, and is widely used in the fields of food and medicine. It has a unique flavor and a good taste. , is also an important foreign exchange earning product for export in Fujian Province. However, the current sampling test results often find that the cadmium content of Agaricus blazei products exceeds the standard. The cadmium content is usually 6-15 mg / kg, and sometimes even as high as 35.2-100 mg / kg, which seriously affects its quality and h...
