Embodiment 1

[0022] Embodiment 1: (shortening the method 1 of Pleurotus eryngii fruiting bag mycelia growth cycle and improving output)

[0023] 1) Preparation and bagging of cultivar culture medium: prepare cultivar culture medium in July to August under natural climate conditions, with a width, thickness, and length of 0.4cm × 0.4cm × 16cm with a total weight of 240g wooden strips, 200g of wheat grains, 50g of cottonseed hulls and 60% of the total weight of the medium are mixed to form a cultivar culture medium, which is put into a polyethylene plastic bag for subsequent use;

[0024] 2) Preparation and bagging of compost for fruiting bags: under natural climate conditions, in August to September, 26% of cottonseed hulls by weight percentage, 9% of mulberry branches sieved through a 30-mesh sieve, 10% of bran, and corn flour 2%, 0.5% lime, 0.5% gypsum, 52% water, mix evenly, and prepare mushroom bag compost; put the compost into polypropylene plastic bags of 17cm×36cm×0.005cm to the heig...

Embodiment 2

[0031] Embodiment 2: (shortening the method 2 of Pleurotus eryngii fruiting bag mycelia growth cycle and improving output)

[0032] In this example, step 1) preparation and bagging of the cultivar culture medium: by 200g of wood strips, 120g of wheat grains, 120g of cottonseed hulls, accounting for 60% of the total weight of the culture medium, mixing and mixing to prepare the cultivar culture medium; 2) Preparation and bagging of compost for fruiting bags: 16% of cottonseed hulls, 19% of mulberry branches passed through a 30-mesh sieve, 10% of bran, 2% of corn flour, 0.5% of lime, 0.5% of gypsum, and 52% of water. %, mixed evenly, and made into fruiting bag compost; step 5) inoculation and cultivation of fruiting bag compost: after inoculation, put it into the bacteria room, at room temperature 25~26°C, relative air humidity 60%, and cultivate in the dark for 30 days; Step 7) Bud-inducing: culture at 13-14° C. for 7-10 days; other steps and processes are the same as in Exampl...

Embodiment 3

[0033] Embodiment 3: (industrialization shortens the method 3 of Pleurotus eryngii fruiting bag mycelia growth cycle and improves output)

[0034] In this example, step 1) preparation and bagging of cultivar culture medium: industrial facility production can prepare cultivar culture medium according to the annual needs, and the width, thickness and length are 220g wooden strips with dimensions of 0.4cm×0.4cm×15cm , 150g of wheat grains, 100g of cottonseed husks, and 60% of the total weight of water, mixed evenly to make a culture medium; step 2) preparation and bagging of the culture material for fruiting bags: factory facilities can prepare mushrooms according to the needs of the year. Bag compost, 17.5% of cottonseed hulls, 17.5% of mulberry twigs passed through a 30-mesh sieve, 10% of bran, 2% of corn flour, 0.5% of lime, 0.5% of gypsum, and 52% of water, mixed evenly to form a fruiting bag Compost; step 5) inoculation and cultivation of fruiting bag compost: after inoculatio...

Abstract

The invention discloses a method for shortening the hypha growth cycle of a pleurotus eryngii fruiting bag and improving yield, which belongs to the technical field of edible mushroom culture. The method comprises the following steps of: the preparation and bagging of a cultivated species culture medium, the preparation and bagging of fruiting bag compost, sterilization, the inoculation and culture of the cultivated species culture medium, the inoculation and culture of the fruiting bag compost, inducement to primordium, mushroom culture, harvesting and the like. Compared with the conventional methods, the method shortens the spawn runing cycle by 20 to 30 days, improves the spawn runing success rate, increases the ratio of high-quality mushrooms as nutrients are completely decomposed and accumulated, improves the biological efficiency to over 70 percent from 35 to 50 percent, shortens the culture cycle to 48 days from about 88 days and remarkably improves economic benefits in the cultivation of pleurotus eryngii, and can be popularized and applied in edible mushroom culture areas.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for shortening the mycelia growth period of Pleurotus eryngii mushroom bag and improving yield. Background technique [0002] Pleurotus eryngii is a large-scale toadstool with good quality. It is native to southern Europe, northern Africa, and Central Asia in alpine, grassland, and desert areas. It is also distributed in Sichuan, Qinghai, and Xinjiang in my country. Pleurotus eryngii has been extensively cultivated because of its thick meat and rich nutrition, and its domestic consumption and export demand are large. Generally, cottonseed hulls, corn cobs, wood chips or wheat straw, bean stalks, bagasse and their compositions are used as the culture substrate, and the production is carried out through the process steps of material preparation → medium preparation → bagging → sterilization → cooling → inoculation → cultivation . Among them, some have a...
