Management of Lentinus edodes growing in summer

The growing stage of Pleurotus ostreatus is in the season of high temperature, which is disadvantageous to the growth and development of fruiting body. Poor management is prone to wilting and rotten mushrooms. How to make use of cultivation and protection facilities and take corresponding measures to restrict the impact of adverse environment? This is the most important link in the management of mushroom cultivation in summer. According to the experience of the main producing areas, the main measures are as follows:

1. Thinning buds and digging plants

The first tide of buried mushroom is from late May to June, when the temperature is more suitable, mushroom buds emerge in clusters, if allowed to develop, it will make small meat thin, which does not meet the quality requirements of fresh-keeping export, so buds must be thinned. Specific operation: for the dense mushroom buds on the surface of the bacteria tube, 6-8 buds with full body, round body, short handle and reasonable distribution are selected for each bag; the excess mushroom buds are crippled by pressing their fingers to prevent them from developing, so as to make the mushroom production distribution reasonable and absorb nutrients and moisture evenly in the fungus bed. to ensure the quality of mushroom products.

2, shading and controlling light

When the temperature of the shed rises in summer, the shade shed should be covered with thatch and branches to avoid direct sunlight. The light source only depends on the weak light in the grass curtain around the shed wall, which is generally controlled in "one yin and nine yang", making the whole mushroom shed in a shady and bleak condition. The choice of mushroom shed sites in summer is suitable for mountain valleys and riversides, where the mountains depend on the water, the air is smooth, and the light is not strong. If the light intensity is too high, the temperature increases, the mushroom body becomes thinner, the color becomes yellow, and the quality is affected.

3. Humidification and cooling

Flow water is irrigated in the furrow during the day, discharged at night, and kept shallow to store water to cool down. But pay attention to the lower limit of the amount of water, which is 20 cm away from the bed surface to prevent water storage from eroding the bacterial cylinder. When the fungus tube is dry, it can be poured directly to the fungus tube with clear water, usually once a day, and can be watered more in sunny days. Remove stagnant water in furrows in time on rainy days. When high temperature can be used every morning and evening with spring water, well water and other lower temperature water, to the roof, around and space spray, so that the shed in a cool environment.

4. Strengthen ventilation

No matter what kind of cultivation. When Pleurotus ostreatus enters the fruiting body growth period, the cover film covering the border bed in the early stage should not be covered tightly, such as 1 bow and 1 shed or 2-3 bow 1 shed, the surrounding film must be rolled away from the border bed more than 30 cm, so that the air between the border bed is smooth. Muggy and dry weather, do not cover the film during the day. If the temperature of the tight film increases and the concentration of carbon dioxide increases, it will inevitably lead to wilting and rotting mushrooms. There are more thundershowers in summer, pay attention to strengthening ventilation and dehumidification, can open a vent for the shade around the mushroom shed, so that the air in the shed can be smooth; at the same time, pay attention to check whether the cover film is broken and leaked into Rain Water to avoid the phenomenon of rotten mushrooms caused by high temperature and rain.

5. Check frequently

Every day combined with mushroom picking, pay attention to observation, find diseases and insect pests or wilting buds, rotten mushrooms, should be removed in time, and the rotten roots should be eradicated, partially wiped with lime water to prevent the spread of pollution. Emphasis is placed on banning pesticides in the growing mushroom period to avoid pollution of the mushroom body.

6. Postharvest continuation

The growth rate of summer mushroom is faster, from mushroom bud to mature mushroom is generally 1-2 days, and it is completed in half a day when the temperature is high, so it is harvested once a day, once in the morning and evening in the peak period, and 4 times a day for fresh-keeping export mushrooms. if it is slightly delayed for a few hours, it does not meet the standard of fresh-keeping export, which is very different from the routine. After the first tide mushroom harvest, stop spraying water, prolong the ventilation time, let the bacterial tube recuperate and recuperate, at the same time, spray 100 times of the available mushroom with insufficient nutrition and stable enrichment to increase the mycelium vitality and increase the yield of regenerated mushroom. Wait for the white hyphae to grow again in the part of picking mushrooms before budding. During the period of high temperature from July to August, we should mainly cultivate bacteria and avoid re-pulling and stimulating mushrooms, otherwise it will damage the mycelium and easily cause rotten tubes.
