How to ensure that Pleurotus ostreatus produces good mushrooms in the later stage

There are many varieties of Pleurotus ostreatus, which can be divided into four categories according to the temperature of mushroom production, namely, high temperature type, wide temperature type, medium temperature type and low temperature type. The Pleurotus ostreatus cultivated in spring is generally wide-temperature type and high-temperature type. The temperature of wide-temperature type is 2 ℃ 30 ℃, and that of high-temperature type 10 Mel 32 min. In production, although the temperature meets the requirements of mushroom production, Pleurotus ostreatus generally produces less mushroom in the later stage, and the quality is not good. In fact, if we can strengthen the late management of spring planting Pleurotus ostreatus, we can still produce more mushrooms and produce good mushrooms as in the early stage.

First, soak in water. The bags of Pleurotus ostreatus planted in spring could not produce mushrooms or only a small amount of small mushrooms could not grow up because of the loss of water in the bags and the dry shrinkage of the family after 3 batches of mushrooms were produced. At this time, immersion treatment can be carried out, and a mud puddle can be dug next to the mushroom farm, which is filled with a 4-layer bacterial bag, covered with wood or bamboo board, and then filled with water after pressing the heavy material, so that the bacterial bag can be immersed in water for 2 times, and a small amount of compound fertilizer can be added to the water to increase the nutrition in the bacterial bag. With the supplement of water and nutrition, Pleurotus ostreatus can continue to produce good mushrooms in the later stage.

Second, cover the soil. As the temperature rises gradually, even higher than the high temperature limit of Pleurotus ostreatus, it often occurs that it can not produce mushrooms or dead mushrooms. At this time, soil treatment can be carried out to reduce the temperature and ensure the emergence of mushrooms. The temperature of the soil is generally 5 ℃ 10 cm lower than the air temperature, and the film can be removed from the mushroom bag and neatly discharged in the border bed, which is covered with soil of 5 cm and 8 cm. Pay attention to the first 3 days of soil mulching, watering 3 times a day, each time thoroughly.

Third, prevention and control of diseases and pests. With the increase of air temperature, the harm of the disease is aggravated, so it is necessary to carry out comprehensive control in time. 1. Clean up the environmental hygiene inside and outside the mushroom farm in time. 2. Every other week, 800 times trichlorfon was sprayed on the periphery of the mushroom farm to reduce the source of insects. 3. In the mushroom farm without mushroom body, 800-fold dichlorvos and 500-fold carbendazim solution are sprayed, but no drugs can be used when there are mushroom buds and mushroom body.
