Woodland cultivation mushroom technology

There are two primary methods for producing conventional edible mushrooms. The first is factory-based production, which requires high-quality facilities and typically involves an investment of over ten million yuan. This makes it unsuitable for large-scale development due to the significant capital requirements. The second method is family-style production, often conducted in greenhouses or mushroom houses, with relatively simple infrastructure spread across suburban areas. However, this approach also faces limitations in achieving large-scale output, as each mu of land requires more than 50,000 yuan for mushroom sheds. Continuous use of fixed facilities can lead to environmental degradation, increased bacterial growth, and higher risks of disease, which may result in lower yields or even total loss. Additionally, the use of pesticides for disease control can lead to contamination and unsafe levels of chemicals in the final product. Beijing has approximately 10 million mu of forest land, with about 1.2 million mu suitable for cultivating edible fungi due to its fast-growing characteristics. Using woodland for mushroom cultivation offers great potential. First, the abundant forest resources allow for large-scale planting without competing with food crops, helping to ease the tension between agriculture and forestry. Second, the shaded canopy in forests reduces the need for artificial insulation, lowering facility costs. Third, the forest environment provides natural conditions—high humidity, moderate temperatures, and good air quality—that are ideal for mushroom growth, reducing the need for artificial climate control. Fourth, the clean air in forests ensures pollution-free production, resulting in high-quality, nutritious mushrooms. Finally, waste from mushroom production can be repurposed as fuel or organic fertilizer, promoting tree growth while minimizing waste, aligning with the principles of ecological agriculture. Cultivating edible mushrooms in the forest involves placing mycelium in open spaces to mimic natural growth. This method can generate higher income compared to traditional crops. A single mu of forest land can yield over 5,000 yuan, with some cases reaching up to 20,000 yuan. Due to its profitability, the area dedicated to forest mushroom cultivation has expanded rapidly in Beijing's suburbs. For example, Tongzhou has seen 10,000 mu of land used for this purpose, while Fangshan and Shunyi have over 1,000 mu each. The cultivation process involves selecting fast-growing forest land with a canopy cover of over 70%. If the trees are not dense enough, shade nets can be used to supplement. Ready-to-use mushroom sticks, either pre-inoculated or made from high-quality materials, should be placed in the forest between April and August. Different mushrooms have different optimal times for planting: Bailing mushrooms from late March to mid-April, shiitake mushrooms from mid-April to May, oyster mushrooms from early May to June, and double-bulge mushrooms from July to early August. Bailing mushrooms are planted by burying them in the soil, while shiitake and oyster mushrooms are often grown using hanging or frame methods, which can also support agritourism. Oyster mushrooms can be buried or grown on walls, and white button mushrooms thrive when planted directly in the ground. Once the mushroom sticks are placed in the forest, careful attention must be given to regulating temperature and humidity to meet the specific needs of each species, ensuring a successful harvest.

Aliphatic Polycarbonates APC

A polymer whose molecular backbone contains aliphatic esters. In other words, the parent nucleus R of the dihydroxyl compound HO -- R -- OH is polycarbonate of aliphatic group (CH2) M, (CH2)O(CH2), -- CH2 -- C(CH3)2 -- CH2 -- etc. It is characterized by low melting temperature, mostly below 60℃, and narrow melting range, greater solubility, low mechanical strength, hydrophilic, poor thermal stability, low glass transition temperature. Most aliphatic polycarbonate have low molecular weight and are mostly viscous liquid at room temperature or microcrystalline substance at low melting temperature. It can be prepared from aliphatic dihydroxyl compounds with dicarbonate or photogasification. Most of them have little industrial value, so their application is very limited.
