Mushroom cover soil material in autumn and winter season
Alumina preparation: The primary materials used are rice husks and river mud, with a weight ratio of approximately 1:10. For every 100 square meters of cultivation area, about 4,000 kg of river mud and 500 kg of rice husks are prepared along with additional ingredients. The river mud is first dried and crushed to ensure proper consistency, while the rice husks are soaked in a 4% lime water solution for roughly 20 hours to enhance decomposition. After soaking, the supplementary materials are fermented to enrich their nutrient content. Once ready, the two components are thoroughly mixed, and water is added to achieve a moisture level of around 20%. The mixture is then sprayed evenly, stirred well, and covered with a plastic film. It is turned every 2 to 4 days, typically 3 to 4 times, until the odor diminishes, indicating that the material is ready for use.
Humus preparation: The ingredients include 600–1,000 kg of cow dung powder, 100 kg of bean cake, 80 kg of calcium magnesium phosphate, 40 kg of urea, 60 kg of lime powder, and 30 kg of gypsum powder. The process begins by selecting a location near a water source, ideally around 25 square meters (sufficient for covering 100 square meters of greenhouse space). The surrounding soil should be at least 10 cm deep to allow for proper layering. All materials are crushed and thoroughly mixed before being spread evenly on the ground. The mixture is then turned over to a depth of more than 20 cm, and the surface is slightly leveled. Water is added to maintain a level of about 5–10 cm above the soil. After approximately 10 days, the watering process is repeated, and the water level is kept consistent. When temperatures rise, especially above 30°C, gas bubbles may appear on the water surface after 7–10 days. If the temperature remains high, turning the pile 3–4 times will result in numerous smelly bubbles forming. Once this stage is complete, the water is drained, and the material is left to air dry naturally. When the surface shows extensive cracks, the top 20 cm of soil is removed and placed on a hardened road to dry. After crushing, the material is treated with the same "cover material treatment agent" solution mentioned earlier. After about 7 days, the humus is ready for use under a plastic film.
