Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.

How do you deal with a lack of water in the substrate during the later stage of oyster mushroom cultivation?
The first flush of oyster mushrooms accounts for about 40% of the total yield. Generally, after the second flush is harvested, because the water in the substrate is almost used up, even if mushrooms can still come out they are sparse, with thin and weak fruiting bodies, loose and dry flesh, and poor taste. To increase the yield, the following methods can be used to supplement water and nutrient solution: (1) The upright bag hole-irrigation method: the soaking method requires a water-holding container, but in some cases a small container or other reasons make it inconvenient, so this method can be used. Stand the fungus bags upright on the floor of the mushroom house, pull up the edges of the plastic bag so that water can be retained after watering, then

What to Do When the Surface of Oyster Mushroom Substrate Turns Black? Cause Analysis and Control Methods
The main causes of blackening on the substrate surface and the control methods are: (1) Oyster mushroom mycelium soaked in water for a long time causes rot and blackening. In this case, the condensation water on the substrate surface should be absorbed and dried promptly. If it is grown on beds, excess water at the bottom should also be absorbed and dried promptly. (2) Contamination by foreign microorganisms and breeding of insect pests cause blackening. When blackening occurs, pests must be controlled or the affected part dug out promptly to prevent it from spreading.

Detailed Explanation of Key Techniques for Oyster Mushroom Cultivation on Sterilized Substrate
1. Preparation of the culture substrate: Select fresh materials free from mold, uniform in coarseness, and remove impurities. Mix the raw materials together in proportion until evenly blended, then add water and stir; control the moisture content at 60%, so that when squeezed into a ball in the hand, slight moisture appears between the fingers but no water drips out. Then fill into bags. 2. Sterilization: Use the high-pressure cabinet sterilization method, holding at 120°C under stable pressure for 2-3 hours; or the steam sterilization method, steaming thoroughly at 100°C and holding for 4-6 hours. A steamer pot can also be used for sterilization: first add water to the pot, attach a steaming rack on top, and cover tightly with pressure. After steam rises from the top layer, sterilize for 10-15 hours.

How to remedy the lack of water in the substrate in the late stage of oyster mushroom production
The yield of the first flush of oyster mushrooms accounts for about 40% of the total yield. Generally, after harvesting the second flush, because the water in the substrate is almost used up, even if mushrooms can still appear, they are few, the fruiting bodies are thin and weak, the flesh is loose and dry, and the taste is poor. To increase the yield, the following methods can be used to replenish water and nutrient solution: (1) Standing-bag hole irrigation method: the soaking method requires a water container, but sometimes because the container is small or for other reasons it is inconvenient, so this method can be used. Stand the fungus bags upright on the floor of the mushroom house, pull up the edges of the plastic bags so that water can be retained after adding it, then

Occurrence Patterns and Integrated Control Methods of Pests and Diseases in Goji Berry
Goji berry is a deciduous shrub of the genus Lycium in the Solanaceae family. Its fruit is called goji berry (Lycii Fructus), and its root bark is called Digupi (Lycii Cortex); both can be used as medicine. The tender stems and leaves are eaten as vegetables. It is distributed throughout China, mostly in the wild. The related species Lycium barbarum (Ningxia goji) is mostly cultivated; its fruit is called Xi goji or Gan goji and is used medicinally, mainly produced in Ningxia, Gansu and Inner Mongolia. Goji berry suffers from pests and diseases at every stage of growth, causing great economic losses to production. The occurrence and control methods of goji berry pests and diseases are introduced as follows: 1 Diseases 1.1 Black fruit disease (anthracnose) Main

What should you do if herbicide is accidentally mixed into oyster mushroom (Pleurotus ostreatus) substrate?
Herbicide should never be mixed into the substrate when growing oyster mushrooms. As for what adverse effects mixing herbicide into the substrate may have on the growth of oyster mushroom mycelium, we have not yet carried out experiments in this area. I think that mixing 50 grams of herbicide into 2000 jin of substrate is not a low concentration; even if it does not affect mycelial growth, at the very least herbicide residues will accumulate in the oyster mushroom fruiting bodies, making it very difficult to guarantee the safety and hygiene of the product. The solution is to repeatedly rinse the herbicide-containing substrate with water (5-6 times), then drain off some of the excess water, add an appropriate amount of carbendazim (reduced by about 20% from the original amount), pile it up for fermentation, and then use the original method for inoculation and cultivation.

Adding table salt to oyster mushroom substrate can increase yields
In oyster mushroom cultivation, using carbendazim to control contamination by foreign fungi is effective, but pesticide residues remain in the mushrooms, which is harmful to human health, and the cost is relatively high. According to experiments: when cultivating oyster mushrooms on raw substrate, adding 1.5 kg of table salt per 100 kg of dry substrate (dissolved in advance in a measured amount of water) and mixing thoroughly can prevent infection by foreign fungi and also bring mushrooms out 5-7 days earlier. At the same time, because table salt is rich in sodium, calcium, magnesium and other metal ions needed for oyster mushroom growth, if a 10% salt solution is sprayed in the early stage of fruiting body differentiation and after each flush is harvested, the mushrooms can be free of pesticide residues and their quality
