Three-dimensional cultivation of Edible Fungi with Pure long crop Straw

For a long time, the culture media for the production of edible fungi in China are mainly sawdust and cottonseed hull, resulting in a shortage of forest resources due to excessive felling of wood, while cottonseed hull has a high price because of its wide range of uses and large dosage. Therefore, the price of raw materials used for the cultivation of edible fungi has increased greatly and the cost has increased. In this way, poor management often leads to poor efficiency or even losses. In view of this situation, the majority of edible mushroom workers in China, after years of exploration, finally selected crop straw for edible fungus cultivation. At that time, the methods of crushing and bagging cultivation and fermented material border bed field cultivation were adopted. The process of the former is cumbersome, while the latter covers a large area, the mushroom body is muddy, the quality is poor and the benefit is not ideal. In order to seek a more effective straw cultivation technology, Mr. Liang Renjun, based on many years of practical experience, combined with the characteristics of the cultivation technology of all kinds of edible fungi in the north and south of our country, creatively make use of straw (straw, wheat straw, etc.) without cutting and crushing, without special equipment, without shelves, without any auxiliary materials, three-dimensional cultivation of edible mushrooms such as Pleurotus ostreatus, Straw Mushroom and Coprinus comatus. And indoor and outdoor can be cultivated, outdoor cultivation does not need to build a shed, saving labor and materials. By using this method, Pleurotus ostreatus, Coprinus comatus and Straw Mushroom can be produced per 10,000 kg (covering an area of only 200m2). This unique cultivation and three-dimensional mushroom production method is more suitable for the requirements of the lateral growth of the mushroom body, makes the flower shape complete and good-looking, and solves the disadvantage of covering soil mushroom body with mud in the outdoor field. And good taste, more loved by consumers and suitable for processing salted mushroom export. At present, the technology has applied for a patent with the State intellectual property Office (Patent Application number: 0110664007).

I. benefit analysis

The three-dimensional cultivation of edible fungi with straw has the advantages of low investment and no risk. And the scale can be large or small, not only can produce 1m-20,000 kg of fresh local sales, but also can produce 100,000 kg, million kg of processed salted mushrooms for export or fresh packaging @ # @ 136 green packaging. Below, we analyze the benefits of single production of Pleurotus ostreatus (Pleurotus ostreatus, Pleurotus ostreatus) and multi-varieties with annual production mode:

1. Benefit analysis of straw three-dimensional cultivation of Pleurotus ostreatus (Pleurotus ostreatus, Pleurotus ostreatus). Among them, rice straw is 0.16 yuan / kg, rice (corn, etc.) is 0.80 yuan / kg, fresh mushrooms (Pleurotus ostreatus, Pleurotus ostreatus, Pleurotus ostreatus) is 1.2 yuan / kg.

2. Benefit Analysis of Annual production Mode of Straw cultivated Edible Fungi in order to meet the market demand, a multi-variety annual production mode can be set up according to the natural environmental conditions, so as to ensure the balanced supply of edible fungi in each period and obtain greater economic benefits. The model is as follows: Pleurotus ostreatus (Pleurotus ostreatus, Pleurotus ostreatus, Pleurotus ostreatus) planted in batches from October to December of that year-Flammulina velutipes planted by → in November-Coprinus comatus with 2000 kg material in → in February the following year-straw mushroom with 12000 kg material in September and tea mushroom with 2000 kg material in → in September.

According to this mode of production, more than 20,000 kilograms of mushrooms can be produced in the whole year, with an output value of more than 60,000 yuan, and a net profit of more than 40,000 yuan (the prices of fresh mushrooms, rice straw and rice are the same as the previous table). As the situation varies from place to place, the benefits are also different. Therefore, producers can formulate an annual production mode suitable for the local market according to the local natural and market conditions.

II. Main technical features

1. Scientific and rational use of straw (straw, wheat straw, etc.) as the culture medium is the key to this technology. anyone who has experience in cultivating edible fungi knows that under the premise of not affecting the mycelium growth of edible fungi, the higher the water content of the medium, the higher the yield. Straw (rice straw, wheat straw, etc.) has the characteristics of loose tissue structure, strong water absorption and good air permeability, and its water content is as high as 70% does not affect mycelium growth. This technology makes good use of this advantage of straw, and the yield of edible fungi is greatly improved.

2. Using grain as seed culture medium to make up for the lack of nitrogen in straw, so as to achieve the purpose of high yield production process (material treatment): heap (induced sterilization)-→ steam treatment (adding rice or corn or wheat before treatment)-→ bagging-→ sterilization-→ cooling-→ inoculation-→ sterilization-→ seed production.

3. Interlayer covering of bacteria is another key part of this technology, which can not only play the role of heat insulation, but also supplement nutrition and increase yield. The technological process of straw three-dimensional cultivation of edible fungi is as follows: material preparation-→ pretemperature-→ stack-→ steam treatment-→ bag-→ bacteria-→ wall mushroom-→ harvest.
