Problems solved by technology

Among the above raw materials, using cottonseed husks and waste cotton as main materials to cultivate edible fungi is relatively less labor-intensive, but the resources are few and the cost is high; straws such as wheat and corn are used to cultivate edible fungi. Returning directly to the field from time to time has resulted in problems such as difficulty in collecting raw materials, relative shortage of resources, rising prices, increased production costs, and increased labor intensity.
Especially in the cotton area, on the one hand, cotton stalks are hard to use and are burned in large areas, causing serious pollution. On the other hand, the problem of insufficient raw materials for the production of edible fungi such as Agaricus bisporus is very prominent. A way to effectively utilize cotton stalks and solve the shortage of raw materials for edible fungi

Embodiment 1

[0033] Cultivation technology of Agaricus bisporus in rapid fermentation bed using crushed cotton stalks:

[0034] Liu Xiuyun, a senior agronomist in Xishiyangu, Qiu County, Hebei Province, prepared 20,000 catties of cotton stalks in February and March 2003. In May, the cotton stalks were crushed according to the technical requirements of the bed-type fermentation cultivation process, and then stacked with a film to prevent rain and humidity. Pre-wet on July 25, build piles and ferment on July 30, finish fermentation on August 20, sow 500 square meters on August 23, cover soil on September 8, enter the mushrooming management period after September 23, 2003 Four crops of autumn mushrooms were harvested, with a yield of 18 catties per square meter. In 2004, three crops of spring mushrooms were harvested, with a yield of 7 catties per square meter and an income of more than 23,000 yuan.

Embodiment 2

[0036] The technology of using pulverized cotton stalks to quickly ferment bag-type cultivation of Coprinus comatus:

[0037]The cotton stalks are crushed and processed into 1-2 cm long finely crushed cotton stalks (slivers), and the ingredients are formulated according to the formula, that is, 85% cotton stalks, 7% chicken manure, 3% cake fertilizer, 1.5% lime, 1% urea, and gypsum 1%, 1% superphosphate, 0.5% ammonium carbonate, when building the heap, add water and mix it with a total material weight of 1.5‰ of Gufengling bacteria liquid, and ferment by turning the heap three times in 8-10 days in summer and 15-10 in autumn. After 20 days of fermentation by turning the pile three times, the rest will be managed according to conventional bag cultivation.

Embodiment 3

[0039] Cultivation of Straw Mushroom in Rapid Fermentation Bed Using Crushed Cotton Stalks

[0040] The cotton stalks are crushed and processed into 4-8 cm long finely broken cotton stalks (slivers), and the ingredients are formulated according to the formula, namely 80.6% of cotton stalks, 11.3% of chicken manure, and 8.1% of white ash. When building a heap, add water and mix it with a total material weight of 1‰ of the mushroom liquid, and after 8-10 days, the fermentation process of turning the heap three times, after that, it will be managed according to the conventional bed cultivation method.

Abstract

The new technology of utilizing crushed cotton stalk in cultivating edible fungi includes crushing cotton stalk into filament, utilizing the filament as main material for the edible fungus culture medium, and spraying Gufengling bacterial liquid in proper amount. The edible fungus culture medium has the composition of cotton stalk 75-90 wt%, supplementary material 10-25 wt% and Gufengling bacterial liquid 0.01-0.05 wt%. The edible fungus culture medium of the present invention has the features of easy-to-obtain material, rich nutrients, low cost, high edible fungus yield, etc.

Description

technical field [0001] The invention relates to the technical field of biophysics and chemistry, in particular to a high-yield and stable-yield technology for cultivating edible fungi using cotton stalks. Background technique [0002] At present, the main raw materials used to cultivate edible fungi at home and abroad are wheat straw, rice straw, corn stalks, corn stamens, cottonseed husks, bagasse, cow dung, horse manure, chicken manure, waste cotton and fungus chaff, etc. It is machined and crushed into a powder with a particle size of 1-3mm as a culture medium. Among the above raw materials, using cottonseed husks and waste cotton as main materials to cultivate edible fungi is relatively less labor-intensive, but the resources are few and the cost is high; straws such as wheat and corn are used to cultivate edible fungi. When returning to the field directly, the problems of difficulty in collecting raw materials, relative shortage of resources, rising prices, increased p...
