Embodiment 1

[0042] In this embodiment, the method for cultivating Agaricus blazei to purify paddy field soil cadmium by using edible fungus residues is to cultivate Agaricus blazei in paddy fields for purification. The present embodiment time is summer.

[0043] This embodiment specifically includes the following steps:

[0044] (1) Preparation of compost:

[0045] The culture material includes the following raw materials in weight percentage: 60% of fungus residue, 25% of rice straw powder, 12% of bran, 1% of gypsum, and 2% of lime.

[0046] The fungus residue is Flammulina velutipes mushroom residue. Use after crushing the fungus residue.

[0047] Firstly, various raw materials are weighed according to the proportion of the formula, firstly the dry materials are mixed and mixed thoroughly, and then water is added to mix until the water content is 60wt%.

[0048] (2) Bagging:

[0049] The size of the plastic bag used for bagging is (2l~22cm)×(42cm). The mushrooms are produced by ho...

Abstract

Provided is a method for cultivating agaricus blazei murill to purify soil cadmium in paddy fields by utilizing edible fungi residues. The method comprises the following steps: (1) preparation of culture materials; (2) bagging; (3) sterilization, inoculation of agaricus blazei murill strains for culture; (4) bag removal and soil burying; (5) fruiting management; (6) harvesting. The method for cultivating agaricus blazei murill to purify soil cadmium in paddy fields by utilizing edible fungi residues has the following beneficial effects: contaminated paddy fields and water ponds can be purified so that cost is reduced; agaricus blazei murill is planted in soil polluted by heavy metal cadmium so that content of cadmium in soil is reduced; large-scale soil polluted by heavy metal cadmium is purified; and the finding makes it possible for low-cost and large-scale purification of soil polluted by cadmium.

Description

technical field [0001] The invention relates to a method for purifying paddy field soil cadmium, in particular to a method for cultivating agaricus blazei with edible fungus residue to purify paddy field soil cadmium. Background technique [0002] Cadmium is a dangerous environmental pollution element, it has only two valence states, namely 0 valence and + 2 valence, and 0 valence cadmium cannot exist stably in soil, so cadmium in soil mainly refers to divalent cadmium and its compounds. Cadmium-containing pollutants enter the soil through various channels, reducing the yield and quality of crops, and endangering human health through the food chain, and leading to further deterioration of the quality of the atmosphere and water environment. Therefore, it has attracted extensive attention from all over the world. At present, there are varying degrees of cadmium pollution in the soil of countries all over the world. The world's average annual discharge of cadmium is 1 millio...
