Description

Technical Field

[0001] The invention relates to the technical field of red pine mushroom cultivation, and in particular to a method for cultivating red pine mushroom in the open air by using cotton stalks. Background Art

[0002] Red pine mushroom is a kind of edible fungus. It has delicate meat, fresh and delicious taste. It can prevent heart diseases, help the digestive system, relieve mental stress, fight cancer cells, etc. Edible fungi contain biologically active substances, such as high molecular weight polysaccharides, β-glucose and RNA complexes, natural organic germanium, nucleic acid degradation products, cAMP and triterpenoid compounds, which are of great value in maintaining human health. Therefore, edible fungi have high medicinal value. The main materials of edible fungi culture materials are mainly divided into two categories: woody materials and herbal materials, which are suitable for different cultivation types.

[0003] The main raw materials used for cultivating red pine mushrooms at home and abroad are wheat straw, rice straw, corn stalks, corn cores, cottonseed husks, sugarcane bagasse, waste cotton and mushroom chaff, etc. Some of them also use cotton stalks to be crushed into powder with a particle size of 1-3mm through mechanical processing as a culture medium. Among the above raw materials, the labor intensity of cultivating red pine mushrooms using cottonseed husks and waste cotton as the main materials is relatively low, but the resources are relatively small and the cost is relatively high; using wheat, corn and other straws to cultivate edible fungi has also caused problems in recent years due to the direct return of straws to the fields when crops are harvested, which has led to the difficulty in collecting raw materials, a relative shortage of resources, rising prices, increased production costs, and increased labor intensity. Especially in cotton-growing areas, on the one hand, cotton stalks are relatively hard to use and are burned on a large scale, causing serious pollution. On the other hand, the problem of insufficient raw materials for red pine mushrooms is very prominent, and it is urgent to find a way to effectively utilize cotton stalks and solve the problem of insufficient raw materials for edible fungi. Summary of the invention

[0004] The present invention aims to solve the above technical problems and provides a method for planting Agaricus tinctorius in the open air using cotton stalks.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] A method for planting Agaricus arborvitae in the open air using cotton stalks comprises the following steps:

[0007] S1. Select cotton straw:

[0008] Choose fresh cotton stalks that are free of mold and have been dried, and then break them into pieces of 2-3 cm in length. Use a multifunctional crusher to process the cotton stalks into cottonwood powder with a length of ≤3 mm, dry them in the sun, and store them for later use.

[0009] S2. Processing of cotton straw:

[0010] Add bran, dry chicken manure, sawdust, complete nutrient of oyster mushroom, mushroom growth hormone, lime, calcium, urea and water and mix well. Finally, add magnesium sulfate and mix for 3-5 minutes. After soaking and fermentation, when the straw is covered with snowflake-like substances, it can be used for cultivation.

[0011] S3, bagging:

[0012] The fermented material is put into a polyethylene bag with a diameter of 30x50cm to obtain a fungus bag;

[0013] S4. Sterilization:

[0014] Put the bagged mushroom bags into the sterilization autoclave quickly and keep them for 2-3 hours.

[0015] S4. Mycelium inoculation:

[0016] When inoculating, take the fungus bag and place it, use a knife to cut open the outer bag of the bag-type fungus bag, take a punching stick with your left hand and dip it in 75% alcohol to punch holes in the fungus bag, and quickly squeeze the fungus into the inoculation hole with an inoculator or manually, so that the fungus hole and the fungus are closely matched without leaving any gaps, and the fungus is slightly raised on the hole surface. Transfer the fungus bag to the sterilized cotton field, and control the temperature at 22-25℃. After the mycelium grows and spreads, the mycelium will generate fermentation heat due to its respiration, which is 3-4℃ higher than the room temperature, so the room temperature can be 3-4℃ lower than the suitable temperature for mycelium growth;

[0017] S5. Mycelium culture:

[0018] After 5-7 days, check whether the mycelium has eaten the material. Turn the pile every 5-7 days. If the infection is found, it should be handled or picked out in time to prevent the spread. After 30-40 days of cultivation in the bag, the mycelium is mature, the mycelium in the bag is wavy or forms a few primordia, and brown water drops appear around the inoculation block. When there are sporadic primordia on the surface of the tube, the bag can be removed and the color can be changed. It can be moved into the cotton field for cultivation about 15 days after the bag is removed and the color is changed.

[0019] S6. Fruiting:

[0020] After the mushroom bags are fully grown for 5-7 days, water is exuded and mushroom buds are visible, untie the two ends of the bag. The relative humidity of the cotton field should be maintained at 85%-95%. The optimum temperature for fruiting mushrooms is 10-25℃. When the mushroom leaves are >3cm, heavy water can be sprayed to promote the growth of the mushroom body.

[0021] S7. Harvesting:

[0022] When the flocculent white hairs on the mushroom top are thicker than the stem or longer than the processing requirements, they are harvested and sold or processed.

[0023] Preferably, the mass ratio of cotton straw, bran, dry chicken manure and sawdust in step 2 is 50-100: 0.5-2: 0.5-2: 0.5-2: 0.5-2.

[0024] Preferably, the moisture content of the fungus bag in step 3 is 50-65%.

[0025] Preferably, the pressure of the high pressure sterilizer is 0.1-0.15 MPa.

[0026] Preferably, the cotton field is covered with a film, and the new soil compacts the film to prevent the disinfectant gas from leaking out, and fumigation and sterilization are performed. 210 ml of formalin stock solution, 210 g of quicklime, and 21 ml of concentrated sulfuric acid are used per 10 square meters. After addition, they are immediately vaporized and injected into the film to disinfect the cotton field.

[0027] Preferably, the order of fumigation and sterilization is to add lime, formalin in sequence, and finally add concentrated sulfuric acid.

[0028] After adopting the above structure, the present invention has the following advantages:

[0029] The invention uses crushed cotton stalks to cultivate edible fungi, which has the advantages of easy raw material acquisition, simple processing, labor-saving and time-saving cultivation, low labor intensity, short production cycle, low cost and high output efficiency. It can not only provide a variety of nutrients required by edible fungi, conform to the production concept of low-carbon environmental protection, but also solve the problem of cotton stalk management difficulties, reduce the burden of relevant planting personnel, and solve the problem that the edible fungi culture material is mainly wood chips, which is not conducive to environmental protection and does not conform to low-carbon environmental protection, so as to achieve the purpose of saving production costs, low-carbon environmental protection, and reducing the difficulty of corn and other stalks. In particular, the culture medium is rich in nutrients, ferments quickly, germinates quickly, mushrooms quickly, grows vigorously, has sufficient stamina, has a short cycle (tight crop), has a large output, high benefits, a wide range of applications, and low labor intensity. At the same time, it can extend the cotton industry chain, reduce cotton planting risks, and reduce environmental pollution. The planting cost can be reduced by 15-40%, the labor intensity can be reduced by 30-50%, the output is increased by 20-60% compared with other stalks, and it is more than 10 times higher than the cottonseed skin produced by the same area of ​​cotton.
