If the selection of the mushroom breeding site is selected in a dark, poorly ventilated or unsanitary place, the contamination of the bacteria is serious, and the mushroom cannot fail to grow normally; some are not strong, but the air circulation is poor due to the mushrooming period. The carbon dioxide content is too high and the poisoning is affected. It is impossible to produce mushrooms or form deformed mushrooms. Therefore, planting oyster mushrooms should first choose a place with good ventilation and scattered light, and keep it clean and hygienic. For the first time to plant mushrooms, the limestone should be painted with walls and the lime should be scattered on the ground for disinfection. The quicklime scattered on the ground should be cleaned up the next day; the old mushroom field can be fumigated with potassium permanganate and formalin; Pests in the mushroom field first spray insecticide to eliminate pests, and then disinfect.
Selection or preparation of culture materials Pleurotus ostreatus is planted with contaminated and agglomerated raw materials, which may cause large-area pollution or no bacteria. When the culture material is prepared, nitrogen fertilizer such as urea is excessively added to the material, and the nitrogen fertilizer is easily decomposed and released to release ammonia gas after inoculation, so that the mycelium is poisoned and cannot be normally infected. Therefore, we must close the good materials and ingredients. To clean the raw materials, and do a good job of disinfection, chemical fertilizers should not be added at the time of dosing. Only when the oyster mushrooms are fermented in the pile, can the urea be supplemented with nitrogen. At the same time, in the process of compounding, special attention should be paid to the humidity of the culture material, and the moisture content should not be too high or too low, otherwise it will be unfavorable to the bacteria.
For the selection of strains, high-temperature varieties are used in winter, low-temperature varieties are used in spring, or strains that have been aging or contaminated are soaked, which are easy to cause slow or no bacteria, and late or not. Therefore, when planting oyster mushrooms, the appropriate strains should be selected according to the local climatic conditions at that time, and no aging or contaminated strains should be used.
Strengthen management of oyster mushrooms under natural temperature conditions, the management of the mushrooming period is light, moisture and ventilation. During the mushrooming period, one can rely on the scattered light to meet the needs. In the mushroom house, the mushroom is not well illuminated, the mushroom is slowly, and it can be supplemented with electric light to induce the mushroom. Air humidity is an important condition for the mushrooming period. In order to increase the humidity and blindly increase the amount of water sprayed, even directly spray water on the mushroom body, some small mushrooms will be suffocated, and some grown mushrooms will also be festered by water stains. black. Therefore, during the mushroom feeding, attention should be paid to the hydration method to spray to the air as well, and at the same time, attention should be paid to ventilation and ventilation to avoid excessive accumulation of carbon dioxide, resulting in the formation of fruiting bodies or the formation of deformed mushrooms. In addition, unreasonable harvesting also affects the increase in yield. Some mushroom farmers are large and small, and they want to keep the small mushroom body growing. As a result, they can not only grow up, but also prolong the mushrooming period and affect the yield of the mushroom.
