Method for improving soil through awn stem matrix

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...

[0005] Chinese Patent Application No. 202010730697.3 provides an organic cultivation method of Stropharia stropharis using wild miscanthus as the main ingredient. Although this method has its advantages, it needs to select fertile soil with a pH of 6.5-7.5, and the fermented material must be fermented with wild miscanthus In addition, it is also necessary to add rice bran, rice husk or miscellaneous wood chips, fermented organic fertilizer, three-element compound fertilizer, gypsum, etc., resulting in certain limitations in the operation of this method in the wild.
