Method for preparing cucumber soilless culture substrate based on shiitake mushroom bran

Abstract

The invention discloses a method for preparing a cucumber soilless culture substrate based on shiitake mushroom bran. The method comprises the following steps that the shiitake mushroom bran which is complete, free of contamination and left after five times of fruiting is chosen and dried in the sun or dried through baking; impurities are removed; the shiitake mushroom bran is crushed by a crusher to have the grain diameter within the range of 1-5mm; lime water is used for regulating the pH to be 7.0, and then water is added for regulating the humidity to be 60%; the shiitake mushroom bran is placed in a closed container and sealed for fermentation at the room temperature; 30 days later, the shiitake mushroom bran is taken out and dried in the sun or dried through baking to be used; the shiitake mushroom bran and peat are mixed according to the weight ratio within the range of 7:3-6:4; after the shiitake mushroom bran and the peat are mixed uniformly, the lime water is used for regulating the pH to be 6.5, and then the mixture can be used; the water content of the mixture ranges from 20% to 30%, and the cucumber soilless culture substrate is obtained. The method for preparing the cucumber soilless culture substrate based on the shiitake mushroom bran has the advantages of being practical, low in preparing cost, simple in preparing method, and convenient to popularize and apply, utilizing the shiitake mushroom bran effectively and reasonably, reducing the waste of the shiitake mushroom bran, lowering the risk caused by the situation that the shiitake mushroom bran is directly thrown in the environment, and increasing the use value of the shiitake mushroom bran.

Description

technical field [0001] The invention relates, in particular, to a preparation method of a cucumber soilless culture substrate based on mushroom chaff. Background technique [0002] More than 800 years ago, China began the semi-artificial cultivation of shiitake mushrooms. At present, China has become the world's largest producer of shiitake mushrooms, with an annual output of 1.68×10 dried mushrooms. 7 kg. While the mushroom industry brings economic benefits, it also brings resource waste and environmental pollution. After harvesting 100kg of fresh mushrooms, 60kg of mushroom chaff will be produced, and the annual output of mushroom chaff in Sichuan Province alone is about 4.81×10 8 kg, these fungus chaffs are rich in nutrients and are easy to spoil and deteriorate, which will cause serious environmental problems and waste of resources. Lentinus edodes is a kind of wood rot edible fungus which mainly uses wood segments, cottonseed shells, sawdust, etc. as carbon nutrients...
