Common problems in the cultivation of Pleurotus eryngii

Pleurotus eryngii is a kind of edible mushroom which has been famous in the world for a long time. Pleurotus eryngii, edible and medicinal, its meat is compact, thick, fresh and delicious. It has rich nutritional value, and more than 40-50 different dishes can be made in our country, which can reduce blood lipids, cholesterol, promote digestion and other effects. There are a wide range of cultivated areas in our country, but there are many common problems in the process of cultivating Pleurotus eryngii.

1. Bacterial bag pollution

Bacterial bag pollution is one of the most common problems in Pleurotus eryngii cultivation. Bacterial bag pollution will cause Pleurotus eryngii to be disturbed by miscellaneous bacteria, affect the normal growth, and lead to the decline of planting efficiency. The main cause of bacteria bag pollution is that the sterilization work is not in place, the material is not watered enough, which leads to the heart in the material, and then the air is not discharged during sterilization, which leads to the existence of air conditioning in the sterilizer and the obstruction of the thermal cycle. Or the lack of sterilization time will lead to bacterial bag contamination.

2. The mycelium grows slowly.

The slow growth of mycelium will prolong the growth cycle of Pleurotus eryngii, lead to the decrease of yield and affect the planting benefit. The slow growth of mycelium may be due to the poor viability of the strain, so we must pay attention to the selection of strains when planting. Then pay attention to the tightness and water content of the bacterial bag during cultivation to ensure that there is sufficient oxygen, and the lack of oxygen is also the main reason for the slow growth of mycelium. Finally, when sending bacteria, we should pay attention to the temperature, keep it above 20 degrees, poor permeability or discomfort of PH value are the reasons for the slow growth of hyphae.

3. Deformed mushroom

Deformed mushroom is also a common problem, abnormal mushroom will seriously affect the appearance of Pleurotus eryngii, reduce or even cause Pleurotus eryngii to lose its commercial value. It is mainly due to the extrusion of the bacterial bag during sterilization, resulting in the deformation of the bacterial bag, resulting in gaps, and then due to temperature discomfort, too much light and various man-made reasons lead to the formation of lateral hyphae to form primordia and develop into fruiting bodies. After finding deformed mushrooms, it is necessary to squeeze the mushroom buds in time to prevent continued growth and avoid consuming more nutrients.

4. The fruiting body is too small

The small fruiting body of Pleurotus eryngii will seriously reduce the yield and affect the planting benefit, which is mainly due to the lack of timely bud thinning. After the primordium differentiation of Pleurotus eryngii, mushroom buds will grow on the side of the bag, but these buds can not continue to grow because of insufficient nutrition and growth space. However, it will continue to consume nutrients, resulting in insufficient nutrition of the fruiting body and unable to expand. Therefore, we must timely thinning buds in cultivation to prevent excessive consumption of nutrients, affecting the growth of fruiting bodies.

5. The mycelium grows vigorously.

The growth of mycelium will cause great harm to Pleurotus eryngii and affect the growth of fruiting body. after the growth of mycelium, the fruiting body will gradually shrink, and in serious cases, the fruiting body will yellowing and die. The exuberant growth of mycelium is mainly caused by the temperature discomfort during mushroom production, and the sudden increase in temperature makes Pleurotus eryngii unable to adapt in time, which provides conditions for mycelial growth. Then in the case of sufficient nutrients, the nutrient water absorption of the mycelium will increase, and even lead to the nutrient flow of the fruiting body to the hyphae, resulting in the vigorous growth of the mycelium and the death of the fruiting body, so we should control the temperature of the mushroom shed to prevent the mycelium from growing.

The above is a brief introduction to the common problems in the cultivation of Pleurotus eryngii. The cultivation of Pleurotus eryngii needs our careful management. Only by doing a good job in all aspects of management can we ensure the normal growth of Pleurotus eryngii, increase the yield of Pleurotus eryngii and expand its own planting efficiency. That's all for today's introduction. This article is for reference only. I hope it can help you all.
