Embodiment 1

[0037] Take wheat straw fragments, the length of the wheat straw fragments is 0.5-1cm, and the width is 3-4mm, soak them in lime water with a concentration of 10%, wherein the lime water is prepared by adding quicklime and tap water, and soak at room temperature for 20 days, And turning it once every 1-2 days, so that the wheat straw fragments are completely soaked in the lime water, and finally the soaked straw fragments are obtained; the soaked straw fragments are dried at 75°C to obtain the morel cultivar culture material.

Embodiment 2

[0039] Take barley straw fragments, the length of the barley straw fragments is 1-1.5cm, and the width is 2-3mm, soak them in lime water with a concentration of 20%, wherein the lime water is prepared by adding quicklime and tap water, soak at room temperature for 29- 30 days, and turned once every 2 days, so that the barley straw fragments are completely soaked in lime water, and finally soaked straw fragments are obtained; the soaked straw fragments are dried at 80° C. to obtain morel cultivar culture materials.

Embodiment 3

[0041] Take oat straw fragments, the length of the oat straw fragments is 1.5-2cm, and the width is 2-3mm, soak them in lime water with a concentration of 12%, wherein the lime water is prepared by adding quicklime and clean machine well water, and soak at room temperature 21-23 days, and turned once every 1-2 days, so that the oat straw fragments are completely soaked in lime water, and finally soaked straw fragments are obtained; the soaked straw fragments are dried at 78°C to obtain morel cultivars.

Abstract

The invention discloses a preparation method of a culture material of a Morchella genus cultivar and a method for cultivating the Morchella genus cultivar by using the culture material. The preparation method comprises the steps: (1), taking crop straw pieces, performing soaking in limewater of a concentration of 10-20%, and conducting soaking at room temperature for 20-30 days so as to obtain soaked straw pieces; and (2), drying the soaked straw pieces obtained in the step (1) at 75-80 DEG C so as to obtain the culture material which is alkaline. The prepared culture material has certain ability of microbial pollution resistance, so that the effects of time and labor saving are achieved at the key step of production of the Morchella genus cultivar; and no sterilization operation is neededin the preparation process of the culture material and the corresponding strain production step, so that the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of hickory chick cultivation; in particular, it relates to a preparation method of hickory chick cultivar culture material; Background technique [0002] Morchella is a precious and rare edible fungus, which belongs to the fungus phylum Ascomycetes, class Panmycetes, Morchella genus (Morchella genus). Morchella is delicious, has high nutritional value, is rich in essential amino acids, polysaccharides and antioxidant substances, and is expensive. Gathering wild morels has been unable to meet the needs of the consumer market. In recent years, breakthroughs have been made in the artificial cultivation of morels, and there are three species: M.importuna, M.sextelata, and M.exima. Mature and stable commercial field cultivation. The cultivation area in China expanded from less than 1,000 mu in 2011 to nearly 70,000 mu in 2017. The rapidly expanding hickory chick cultivation area means the demand for a huge am...
