Example Embodiment

[0027] Example 1

[0028] A method of matriculation to improve poor soil, the unfined mango pole (160-400 cm) is flattened under the forest with a well-opened groove, the thickness of the mango pole is 15 cm, the bottom of the mango pole is pressed against the top of the mango pole, paved first watered, and then inoculated with large bulbous cover mushrooms, the strains are about 140g per small piece, the spacing is 20 cm, the width is 20 cm, a total of two rows; after inoculation, the second layer of the mango stick is covered in the same way 15 cm, after watering, Cover the gravel soil with 0.8% organic matter content, the soil thickness is about 3 cm, and then water it thoroughly. Continue to water every day, carry out germination period management, mushroom production, mushroom picking and other operations. Bulbous mushrooms have been tested in line with GB 7096-2003 edible mushroom hygiene standards. After the mushroom picking, the incompletely decayed mango pole is built int...

[0029] Example 2

[0030] A method of matriculation to improve poor soil, the broken mango pole (5-80 cm) is flattened under the forest with a well-opened trench, the thickness of the mango pole is 15 cm, after laying, it is first watered, and then inoculated with large bulbous cover mushrooms, the strains are about 70g per small piece, the spacing is 20 cm, the width is 20 cm, a total of three rows; after inoculation, cover the second layer of mangoste 15 cm, after watering, cover the gravel soil with an organic matter content of 0.76%, the soil thickness is about 4 cm, and then watered. Germination period management, mushroom production, mushroom picking, large bulbous mushroom after testing in line with GB 7096-2003 edible mushroom hygiene standards. After the mushroom picking, the rotting mangospoon is fertilized in situ under the forest, and the organic matter content of the soil under the forest reaches 12%.

Example Embodiment

[0031] Example 3

[0032] A method of matriculation to improve poor soil, the crushed mango pole is built into a pile of water, and then add 1% (mass fraction) of quicklime water, stir evenly, until the temperature rises to 50 ° C or more to maintain 2-3 days of turning the pile, repeated 2 times, 15 days after the fermentation material is flattened under the forest of the open groove, the thickness of the manganese is 15cm, inoculated with large bulbous cover mushrooms, the strains are about 70g per piece, the spacing is 20cm, the width is 20cm, a total of three rows; after inoculation, cover the second layer of mangrove 15cm, after pouring, Cover the gravel soil with 0.95% organic matter content, cover the soil with a thickness of 3 cm, and then water. Germination period management, mushroom production, mushroom picking, large bulbous mushroom after testing in line with GB 7096-2003 edible mushroom hygiene standards. After the mushroom picking, the rotting mangosteen is fertiliz...

Abstract

The invention discloses a method for improving barren soil through awn stem matrix. According to the method, wild awn stems serve as main raw materials, the principle of taking materials nearby is adopted, the awn stems are adopted to cultivate stropharia rugoso-annulata in the barren soil under the forest, and the awn stems serve as organic fertilizer to be returned to the forest after mushroom planting so as to increase soil organic matter. The method comprises the following steps: (1) pretreating awn stems; (2) tiling the awn stems in the forest land after soil preparation; (3) sowing stropharia rugoso-annulata on the awn stem piles; (4) performing spawn running, fruiting and harvesting operation on the stropharia rugoso-annulata; (5) returning the miscanthus stems subjected to crushing pretreatment in the step (1) as an organic fertilizer to a forest, and improving forest land soil; or the miscanthus stems which are not subjected to crushing pretreatment in the step (1) are piled, fermented, returned to forest and fertilized, and soil is improved. According to the method, the wild awn stems are used as edible fungus cultivation raw materials to the maximum extent, meanwhile, the organic matter in the barren soil is increased, and after the awn stems are used for cultivating stropharia rugoso-annulata, the organic matter content of the barren soil is increased to 10%-16% from 1% or below.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and at the same time relates to the technical field of edible fungus cultivation, in particular to a method for improving barren soil by using wild stalks to cultivate stropharia stropharia and returning fungi residues to forest substrates. Background technique [0002] M.Scanthus sine sis, also known as Bamaogan, Wujiemang, etc., belongs to Poaceae (Poaceae), Agrostidoideae (Agrostidoideae), Miscanthus (Andropogoneae), perennial tall herb, mainly distributed in Northeast my country, East China, Central South and Southwest China. Grass has the characteristics of wide distribution, fast growth, high yield, regeneration, and fixation of atmospheric carbon dioxide, which provides a new solution to the problem of "global warming". [0003] The content of cellulose in miscanthus stalks (where leaves account for 30% of the total amount of stalks) is 30.36-48.23%, the content of hemicellulose i...
