Embodiment 1

[0018] Embodiment one: a kind of mushroom cultivation substrate

[0019] A mushroom cultivation substrate is composed of solid materials and water, and the percentages of each solid material in the total weight of the solid materials are as follows: 80% of broad-leaved wood chips; 16% of bran; 1% of sucrose; 1% of gypsum powder; 1% of calcium magnesium phosphate fertilizer; 1% compound fertilizer; the content of water in the mushroom cultivation substrate accounts for 60% of the total weight of solid materials.

Embodiment 2

[0020] Embodiment two: a kind of mushroom cultivation substrate

[0021] A kind of mushroom culture medium, is made up of solid material and water, and the weight of each solid material is as follows: 40kg of broad-leaved wood chips, 8kg of bran, 0.5kg of sucrose, 0.5kg of gypsum powder, 0.5kg of calcium magnesium phosphate fertilizer, 0.5kg of compound fertilizer; The water content in the matrix was 30 kg.

Embodiment 3

[0023] A mushroom cultivation substrate is composed of solid materials and water, and the percentages of each solid material in the total weight of the solid materials are as follows: 79% of broad-leaved wood chips; 16.3% of bran; 1.2% of sucrose; 1.2% of gypsum powder; 1.5% of calcium magnesium phosphate fertilizer; The compound fertilizer is 0.8%; the water content in the mushroom cultivation medium accounts for 62% of the total weight of the solid material.

Abstract

The invention relates to a mushroom cultivation substrate, which consists of solid materials and water. The mushroom cultivation substrate is characterized in that the solid materials comprise by weight 78-82% of broad-leaf tree sawdust, 14-20% of wheat bran, 0.8-1.2% of sucrose, 0.7-1.2% of gypsum powder, 0.8-1.5% of fused calcium-magnesium phosphate fertilizer, and 0.8-1.5% of a compound fertilizer, and that water in the mushroom cultivation substrate accounts for 58-62% of the total weight of the solid materials. According to the mushroom cultivation substrate, fused calcium-magnesium phosphate fertilizer and the compound fertilizer serving as mushroom heavy metal modifying agents are added in the conventional cultivation substrate of the mushroom, the addition amount of fused calcium-magnesium phosphate fertilizer and the compound fertilizer is within the range of 0.8-1.5%, so that the cadmium content in the mushroom is reduced by 18-39.6%, and the mercury content is reduced by 19.9-29%; moreover, the accumulation function of the heavy metals can be reduced to the largest degree, and the adverse effects on important agronomic characteristics such as mycelium spreading speed, yields and the like are avoided.

Description

technical field [0001] The invention relates to an edible fungus cultivation substrate, in particular to a shiitake mushroom cultivation substrate. Background technique [0002] Edible fungi is a characteristic and advantageous industry in Fujian. In 2009, the total output of edible fungi in the province was 1.9698 million tons (fresh products), an increase of 2.77%; the output value was 8.682 billion yuan, an increase of 9.52%. The output and output value of rare edible fungi in the province are 545,200 tons and 2.544 billion yuan respectively, accounting for 27.68% of the total output of edible fungi, and the output value accounts for 29.30%. new contribution. Under the background that the overall situation of the edible fungi industry in our province is good, there are still hidden dangers and problems in the safe production of edible fungi and the export of edible fungi. [0003] In view of the current situation of heavy metal pollution in soil and water, the problem o...
