Pleurotus ostreatus imitation wild cultivation techniques
In recent years, diseases have occurred frequently during the cultivation of oyster mushrooms. This is mainly due to the fact that the whole production process is under protection conditions from beginning to end, and the vibrancy and disease resistance of the mycelium are continuously reduced. Using the imitation of wild cultivation techniques can better solve this problem. First, the base material preparation, bacteria bags are routinely carried out. Second, code building code wall. When the individual bacteria bags show their original base, they can build a wall of bacteria. The fungus wall is generally 0.8 meters wide and 15 meters long; the gap at the end of the mushroom stump is muddy and wiped with mud, and other voids are filled with manure and watered to make it sink. The top of the wall was covered with a thick soil of about 8 cm, and a water tank was built. The groove was about 50 cm wide. The path between the two bacteria walls is 1.5 meters wide for easy operation. Third, set up a protective shed. After the bacterium wall is built, it must be erected with a shed to protect it. The arch shed is about 1.8 meters high. The method is: insert one end of the bamboo into the edge of the top of the bacteria wall, and insert the other end into the edge of the water storage tank adjacent to the scum wall, and cover the plastic film. That is, a small shed is set up between the adjacent two vegetative walls, and the two ends are plastic. Membrane seals, one of which is provided with a flap to facilitate access. Points to note: First, the arch piece should be inserted deep so that the arch is firm; second, the cover used on the arch should be easy to expose, cover the grass and other objects, such as in March, November, often need to expose the temperature, During April-May and August-October, it is necessary to tightly cover the grass. When the temperature is high, grasshoppers should be thickened to avoid excessive heating in the arch. Fourth, management. (1) Water management. First of all, it is necessary to maintain a certain amount of water in the water storage tank so as to make it infiltrate slowly. Generally, the air humidity in the arch shed can be maintained at about 85%. No water spray is needed to humidify the water. However, when the spring is dry, the air humidity in the shed is not easy to maintain. Therefore, in addition to the enhancement of water storage tanks, a water ditching trench about 15 cm wide can be dug in front of the tunnel inside the shed, and water can be poured to make the water slower. Slowly seep into the ground to maintain the humidity in the shed. In addition, when the outside air temperature is relatively high, water spray on grasshoppers and other coverings can often play a significant cooling effect. (2) Pest control. The cultivation method is more likely to invade pests than greenhouse or indoor cultivation, so pest control can not be ignored. In the wild, the special odor of mycelium can easily induce pests such as mushroom mosquito, mushroom fly, and springtail to taste. The prevention and control measures include: bury the stump completely in the soil and cover the soil with a thickness of 8 cm; the ends of the wall must also be filled with 3 cm thick soil, and try not to make it dry; the entire open-air vegetative wall is completely surrounded by mud and covered. Make pests accessible without holes. When entering the shed, it should be observed at any time whether harmful insects enter. When pests are found at the initial stage, they are sprayed immediately to kill harmful spirits, and the enemy kills them to kill them, leaving no trouble. (3) temperature management. First, the strain should be selected correctly. Secondly, the thickening of the covering, such as covering the double layer of grasshoppers, can effectively prevent temperature exchanges inside and outside the shed, so as to achieve a relatively stable shelf temperature. When the temperature is low in March and November, the grassland is properly uncovered and the temperature of the greenhouse is raised. In April and October, the temperature is extremely beneficial to the growth of the oyster mushroom, and a layer of grasshopper can be covered to allow natural growth; When it is too high, spray water on the grass while thickening the cover. Thirdly, when the light is strong and the temperature is too high, a shade net can be placed over the cultivation ground so that the arch shed and the bacterium wall are in a half-negative and half-yang environment. In addition, every shade, fog and light rain, the shed film can be removed, only covered with a layer of grasshopper, so that the fruiting body in the wild, so that its shape, color and other more wild mushroom quality.
