Agricultural suggestions on edible fungi in September, prevention and control of diseases and insect pests of edible fungi

Pleurotus ostreatus: for the farmers who are cultivated in early autumn, most of the edible fungi enter the cultivation period, some farmers come out of the mushroom bag and enter the fungus generation period, and some have entered the mushroom production management. At this time, the cultivation of bacteria should be kept dry and ventilated as far as possible, and the pollution of Alternaria, Mucor and other miscellaneous bacteria should be strictly controlled and prevented; the occurrence of "burning bacteria" should be strictly prevented when the bacteria come out of the mushroom bag. 100,150 times mushroom disinfestation king solution can be sprayed on the space and wall of the fungus room (shed) every 3-5 days. Those who enter the management of mushroom production should pay attention to pest control, and the most harmful ones are jumping insects, mushroom mosquitoes and nematodes. Aluminum phosphide can be used to kill thoroughly before or during the tide.

Flammulina velutipes: cultivated in ordinary houses and plastic greenhouses. According to the market supply plan, cultivated or original species can be produced this month. It is necessary to reduce the C / N (C / N ratio) of the cultivation base material properly. The basic formula is: cottonseed hull 70 kg, sawdust (or corncob) 20 kg, wheat bran 10 kg, on this basis, we can appropriately increase the amount of wheat bran and increase the proportion of organic nitrogen in the base material, so as to improve the speed of bacteria formation. Pleurotus ostreatus and Coprinus comatus should be managed during the germicidal period, and pay attention to insect control and miscellaneous elimination.

Pleurotus ostreatus: sowing in the first ten days, note: the fermentation maturity of the base material, it is strictly forbidden to bring miscellaneous bacteria into the shed; strictly check the bacteria, do not use bundles, aging, water-collapsing bacteria; bacteria after long-distance transportation should also be checked to see if they carry (mites) worms; those with acid and odor in wheat grain matrix should be eliminated; pay attention to ventilation after sowing for 3 days, and so on.

When producing hericium Erinaceus, it should be noted that the pH value of matrix should not be too high, it is appropriate to maintain it at a medium level, and drugs such as carbendazim or lime should not be added.

The fungus generation of Lentinus edodes bag is coming to an end, and the temperature difference in early autumn is large, so pay attention to prevent some insects from entering the culture room at night. Moreover, under the condition that grain production is still an important part of the busy agricultural season, we should pay attention to the reasonable arrangement of edible fungus production and field labor, so as not to make them conflict in time and labor.
