Problems solved by technology

However, due to the high moisture content of the water hyacinth plant, it is not easy to dry, and the original carbon-nitrogen ratio is not reasonable enough, which limits its wide application in the cultivation of edible fungi as a culture material for edible fungi.

Embodiment 1

[0033] The water hyacinth is fully aired to reduce the water content of the plant to 10%. Cut off the petiole and fix the tissue cells, the method is as follows: put the petiole into 0.4% glacial acetic acid solution for pre-fixation, take it out after half an hour, put it in 95% ethanol solution for 2 hours, take it out, and then put it in 70% ethanol Fix in the liquid for half an hour, take out the petiole, and shake off the residual fixative in a ventilated place. Cut the petiole lengthwise into thin strips, and bundle several thin strips into a bundle. Then, put it into the biogas slurry pond of the pig farm and soak for 8 days, pick it up, dry it in the sun, and crush it, and then it can be used as a culture material for edible fungi. It was determined that the total nitrogen content of the compost was 4.42%, the total phosphorus content was 2.64%, and the crude ash content was 25.42%.

Abstract

The invention discloses a method for preparing the substrates of edible mushrooms of water hyacinth, comprising the following steps: the water hyacinth is air-cured so as to reduce the moisture content of the plant thereof to 8 present to 12 percent, the leafstalk is treated by adopting the method of plant tissue cell fixation, then the treated leafstalk is put into hoggery-pigsty washing liquor or Biogas Slurry to be soaked for 7 to 10 days, and then is taken out, dried and crushed, then the substrate of edible mushrooms which can replace the sawdust and improve the amino acid content is obtained. The invention has the advantages that the invention overcomes the original defective characteristic of the leafstalk of the water hyacinth, and provides a substrate of edible mushroom which can replace the sawdust and improve the amino acid content. While making the waste water hyacinth profitable, the invention reduces the dependence of the production of the edible mushrooms on the sawdust.

Description

technical field [0001] The invention relates to a method for preparing edible fungus culture material, in particular to a method for preparing edible fungus culture material by using water hyacinth. Background technique [0002] Edible fungus cultivation usually uses wood chips, rice straw, corn stalks, etc. as main materials to provide the cellulose and lignin required for edible fungus cultivation. Especially the large-scale use of sawdust requires the consumption of a large amount of wood. Therefore, while the production of edible fungi brings income to farmers, it also causes serious damage to the rural ecological environment. Water hyacinth plants are rich in crude fiber, which can theoretically be used as raw materials for cellulose and lignin in edible mushroom cultivation. However, due to the high water content of water hyacinth plants, it is not easy to dry in the sun, and the original carbon-to-nitrogen ratio is not reasonable enough, which limits its wide applica...
