In early winter, laying ducks are prone to "reverse molting", so farmers should beware of a drop in egg production rate
"Reverse molting" in laying ducks refers to female ducks raised in spring that enter the laying period in November, when the temperature gradually turns colder, and the day-night temperature difference is too large or nutrition is insufficient, causing ducks that have just started laying to stop producing and go on "vacation". If laying ducks begin "reverse molting", they start to molt, and once molting begins they will not lay eggs again until the following spring. If duck "reverse molting" can be controlled during this period, the laying period can be greatly extended and the economic benefits of duck farming increased. When ducks show signs of "reverse molting" such as eggs becoming smaller, eggshells becoming thinner, delayed laying time, wet feathers after drinking water and coming ashore, and crowding into the duck house, measures should be taken promptly

How to prevent rice sheath blight? Beware of high temperature and high humidity weather
Sheath blight, also known as banded leaf blight, has a great impact on the growth and development of rice. It not only weakens the absorption capacity of the root system, but also affects the photosynthesis of leaves, resulting in an increase in empty and shriveled grains, a decrease in 1000-grain weight and a decline in yield. Therefore, attention should be paid to the prevention and control of sheath blight in production. The following introduces the main symptoms, occurrence characteristics and control methods of this disease for reference.

After the first harvest of oyster mushrooms, beware of bacterial diseases
During the fruiting stage, oyster mushrooms are susceptible to infection by harmful bacteria, so bacterial diseases such as soft rot and spot disease often occur. On December 13, the reporter saw in some mushroom sheds in Zhujiaya Village, Tianliu Town, Shouguang City that the two ends of some mushroom bags after the first harvest of oyster mushrooms showed dark brown watery rot, making it difficult for the second flush to fruit. The reporter's analysis suggests that this situation is soft rot caused by bacterial infection. When oyster mushroom soft rot occurs, the mycelium degenerates, the surface of the substrate bag darkens, softens, and becomes water-soaked and rotten, accompanied by a foul odor. To summarize the causes of the disease in their sheds
