Preparation method of soil-loosening gas-permeable edible mushrooms water-retaining agent

Abstract

The invention discloses a preparation method of a soil-loosening gas-permeable edible mushrooms water-retaining agent and belongs to the technical field of preparation of agricultural materials. The preparation method comprises the following steps: firstly, promoting mosses to grow on surfaces of sepiolite by utilizing peat mosses; carrying out micro-corrosion treatment on the surfaces of the sepiolite by utilizing moss root secreted fluid, so as to increase the quantity of active groups on the surfaces and provide attachment sites for hydrophilic groups; carrying out secondary modification on the sepiolite under the action of microorganisms through utilizing seaweeds and fruit plants, which contain rich hydrophilic carboxyl groups and amino groups, so as to enable the sepiolite has extremely good hydrophilic property; combining extremely high adsorbability and water absorption property of the sepiolite so as to realize a water-retaining aim. Furthermore, the sepiolite is expanded when absorbing water and the volume becomes large so that soil can be supported and the effects of loosening the soil and ventilating are realized. The edible mushroom water-retaining agent disclosed by the invention has an extremely good utilization prospect.

Description

technical field [0001] The invention discloses a method for preparing a water-retaining agent for edible fungus with loose soil and permeable water, and belongs to the technical field of agricultural material preparation. Background technique [0002] Edible mushrooms are edible mushrooms. Mushroom is a general term for higher fungi that can form large fleshy (or gelatinous) fruiting bodies or sclerotia. At present, more than 120,000 species of fungi have been described in the world, more than 6,000 species can form large fruiting bodies or sclerotia, and more than 2,000 species can be eaten. Among them, there are only 40 to 50 species that can be artificially cultivated in a large area. At present, my country mainly uses the form of "mushroom sticks" to carry out artificial mass cultivation of edible fungi. [0003] In the traditional edible fungus production process, the edible fungus culture medium loses water seriously in the later stage, often because the culture mate...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention: Aiming at the defects that most common water-retaining agents for edible fungi are mainly high-molecular polymers, which are not easy to biodegrade, pollute the environment and have poor air permeability, resulting in moldy and rotten fungus sticks, it provides a first-use The method of treating sepiolite with moss, and then using seaweed and fruits and plants rich in hydrophilic groups to carry out secondary modification on the treated sepiolite to finally obtain a water-retaining agent. The present invention first uses peat moss to promote sea foam Moss grows on the surface of the sepiolite, and the moss rhizosphere exudate is used to slightly rot the surface of the sepiolite to increase the number of surface active groups and provide attachment sites for the hydrophilic groups. Seaweed and fruit plants, under the action of microorganisms, the sepiolite is modified twice to increase the number of hydrophilic groups on the surface of the sepiolite, so that it has excellent hydrophilicity, and combined with the sepiolite itself is extremely Strong adsorption and water absorption to achieve the purpose of water retention. In addition, sepiolite will expand after absorbing water, and at the same time it can prop up the soil when its volume becomes larger, which can loosen the soil and breathe. The edible fungus water retention agent of the present invention has good biodegradability , not easy to cause environmental pollution, has excellent application prospects
