Problems solved by technology

[0003] As the leading product of my country's agriculture, cotton has a large cultivation area. According to relevant statistics, the cotton cultivation area in my country is about 76.5 million mu, and it can produce about 23 million tons of cotton stalks every year. This is a large biological resource. Its nutritional content It is not much lower than cotton seed hulls. For a long time, except for a small number of cotton straws used as industrial raw materials, most of them are burned or discarded as fuel, resulting in waste of resources and environmental pollution, and their application value has not been fully utilized.
In July 2000, Chinese patent CN1260945A disclosed the technical scheme of Wuhan Chen Yongxiang's "New Technology and Formula for Cultivating Edible Fungi Using Cotton Stalks", which used 70-96% cotton stalk powder to add mixture to cultivate edible fungi, because the proportion of cotton stalks was too high. It is easy to cause nutritional deficiencies to affect the yield. At the same time, the mixture used in the scheme does not disclose the essential content, and those skilled in the art cannot apply it; in April 2005, Chinese patent CN1608410A disclosed the technology of Fu Zhenqiang in Shijiazhuang, Hebei using cotton stalks to cultivate edible fungi scheme, which processes cotton stalks into 1-8cm filaments, and uses fermented materials to cultivate mushrooms, Coprinus comatus and other edible fungi. However, since the proportion of cotton stalks used is as high as 75-90%, nutrients such as bran and corn flour If the amount of material used is too small, it is easy to cause nutritional deficiency and affect the output; the technical plan does not involve the cultivation of Flammulina velutipes

Embodiment 1

[0015] 1. Select compost: choose cotton stalks as compost for Flammulina velutipes;

[0016] 2. Collection and crushing of compost: in the cotton harvest season, dry the fresh cotton stalks in time, control the moisture content at 12-16%, and remove the root soil; then use a pulverizer to crush the dried cotton stalks , form cotton straw powder, and the crushed particle size is less than 6mm.

[0017] 3. Packaging of compost: the crushed cotton straw powder is packed quantitatively in plastic woven bags, each bag weighing 50kg.

[0018] 4. The preferred medium formula is: 55% cotton stalks, 24% rice bran, 10% corn flour, 10% sawdust, 1% light calcium carbonate; water content 63%.

[0019] 5. The preparation method of the culture medium is: weigh the crushed cotton stalks and other raw materials according to the formula ratio, first put the dry materials of cotton stalks, sawdust and rice bran into the mixer and stir for 5 minutes, add water with a water content of 50% and the...

Embodiment 2

[0021] 1. Select compost: choose cotton stalks as compost for Flammulina velutipes;

[0022] 2. Collection and crushing of compost: During the cotton harvest season, dry the fresh cotton stalks in time, control the moisture content at about 15%, and remove the root soil; then use a pulverizer to crush the dried cotton stalks. Cotton straw powder is formed, and the crushed particle size is about 4mm.

[0023] 3. Packaging of compost: Pack the pulverized cotton straw powder quantitatively in plastic woven bags, each bag weighing 30kg.

[0024] 4. The preferred medium formula is: 50% cotton stalks, 25% rice bran, 14% corn flour, 10% sawdust, 1% light calcium carbonate; water content is about 60%.

[0025] 5. The preparation method of the culture medium is: weigh the crushed cotton stalks and other raw materials according to the formula ratio, first put the dry materials of cotton stalks, sawdust and rice bran into the mixer and stir for 10 minutes, then add water with a water co...

Abstract

The invention belongs to the field of edible mushroom production and discloses a needle mushroom culturing material and a method for preparing a needle mushroom culture medium by using the same. The culturing material mainly comprises the following components: 36%-55% of pulverized cotton straws with the pulverized grain size of 0.1-6 mm, 26%-33% of rice bran, 8%-13% of corn flour, 8%-13% of sawdust and 0.8%-1.8% of light calcium carbonate with the water content of 58%-65%. The method for preparing the culture medium comprises the following steps of: stirring dry materials comprising the cotton straws, the sawdust and the like for 5-10 minutes by the proportions in a formula, adding a proper amount of water and then stirring for 15-20 minutes; adding the corn flour and the light calcium carbonat and stirring for 10-15 minutes; adding the water until the water accounts for 58%-65% and then stirring for 15-20 minutes so that various raw materials and the water are fully and uniformly stirred. The cotton straws utilized in the method has abundant nutriment and low prices, the nutrient components of the cotton straws are not lower than those of cotton seed hulls, and the price of the cotton straws is only 1 / 4-1 / 2 of the price of the cotton seed hulls, thereby the production cost of the needle mushroom can be reduced by using the cotton straws for replacing the cotton seed hulls toculture the needle mushroom.

Description

technical field [0001] The invention relates to a culture material of Flammulina velutipes and a method for preparing a medium for Flammulina velutipes by using the culture material, in particular to a method for using cotton stalks and preparing a culture medium for cotton stalks, which belongs to the field of edible fungus production. Background technique [0002] Flammulina velutipes contains a lot of amino acids, especially lysine and arginine. Eating more Flammulina velutipes can promote the growth and development of children and enhance memory. Improve intelligence, so Japan and other countries call Flammulina velutipes "wisdom-enhancing mushrooms". In my country, Flammulina velutipes is also one of the four main edible fungus varieties with large production and consumption. Because Flammulina velutipes is a low-temperature edible fungus, the suitable temperature for the growth of its fruiting bodies is 3-15°C. Therefore, conventional production can only be cultivated...
