High yield of Pleurotus ostreatus: cut into pieces and stand up and cover soil

Through many years of cultivation practice of Pleurotus ostreatus in Dongkan Town, Binhai County, Jiangsu Province, the six-character classics of "slicing, standing up and covering soil" for the high yield of Pleurotus ostreatus were found, which increased the yield of Pleurotus ostreatus by more than 2000 jin per mu compared with the past, and increased production by about 30%. At the same time, the production cost has been greatly reduced. The experience of high yield is mainly three links: "cutting, standing and covering soil".

The so-called "slicing" means that at the end of the harvest of the second tide mushroom cultivated in the border bed, clean up the residual dead mushrooms and fungal stalks on the bed, and use a sharp knife to cut the cultivated material into several bacterial lumps of about 50 cm × 20 cm. Then use a shovel to insert and swing a few times from under the culture material to pick up the fungus block. The requirement of slicing is that the sharp knife must be cut off perpendicular to the cultivated material, and the fungus should be cut smooth and shaped around it. Be careful not to break the fungus at the end of the shovel.

The so-called "stand up" is to shovel up the bacteria one by one. The requirement to stand up is to clean the bed or border surface, sprinkle a layer of dry lime, and then line up the bacteria. The line spacing is 30 cm, facing the vent. If the old fungus skin is cut open with a sharp knife on the bottom of the fungus, the mildew and rot should be dug out and sprinkled with dry lime; when the mildew of individual clots is serious, the clots can be transported to other places for isolation treatment; when some clots lose water seriously, they can be immersed in water. After slicing and standing, the management method is the same as the general management of border bed cultivation.

After the third harvest of Pleurotus ostreatus, the material surface was cleaned, and then the above 50 cm × 20 cm bacterial mass was subdivided into 4-6 small bacterial clumps by the same method for the management of the fourth Pleurotus ostreatus.

The so-called "covering the soil" means that after the fourth tide mushroom harvest is finished, the small bacteria are set up and buried in the winter idle rice fields or vegetable fields and open spaces. The distance between the bacterial clumps is 8 cm, and the soil water content of the covered soil is 70% 75%, and the pH value is 7% 7.5. The thickness of the covered soil should be 2cm to 3cm, and the soil on the surface should be loose. Strengthen the management after covering the soil, keep the soil surface moist, externally use the support for arch, cover the film, and shade. After the mycelium grows all over the soil for one month, increase the ventilation rate to ensure that the fruiting body can be unearthed smoothly. Its management method is the same as that of border bed cultivation. If well managed, you can also receive 1 / 2 tide mushrooms.

This method has many advantages. First, it has the advantages of large mushroom area, high yield and good quality. The effective mushroom area is 3-5 times higher than the original. Second, disease prevention is good. The seedling does not accumulate water or rot when spraying water. The upright bacterial masses have good ventilation with each other, and it is not easy for miscellaneous bacteria to grow. Third, covering soil can keep heat, moisturize, add nutrients, and the mushroom quality is good. Fourth, with little or no increase in investment, the mushroom area can be increased and the output can be increased. However, it must be organically combined with supplementary nutrients in practice.
