A sweet pepper farmer from Li Er Village, Shengcheng Street, Shouguang City asked: "My family's sweet peppers are showing red leaves, and even the small fruits that have just set are starting to turn dark red. What kind of disease is this, and what should I do?"
According to the information, the farmer has been growing sweet peppers for many years in an old greenhouse. The symptoms described are likely due to low temperatures inside the greenhouse. When peppers are exposed to cold conditions, anthocyanins—natural pigments found in plants—can accumulate more quickly in young leaves and fruits, causing them to appear red or purple. This is a common physiological response to temperature stress.
In addition, the low temperature can also reduce root activity, leading to poor nutrient uptake, especially phosphorus deficiency. This further contributes to the discoloration and stunted growth observed in the plants.
To address the issue, it's recommended to spray the plants with a foliar fertilizer such as "Harvest Number One" diluted at 800 times. Apply this solution every 5 to 7 days. At the same time, it's important to raise the temperature inside the greenhouse, particularly the soil temperature. Covering the ground with a plastic film or mulch can help retain heat and improve root function.
By taking these steps, the farmer can help the plants recover and prevent further damage caused by the cold environment. It’s also advisable to monitor the temperature regularly and adjust greenhouse conditions accordingly to ensure optimal growing conditions for the sweet peppers.
Pelvic External Fixation
There are two kinds of external fixations for pelvic fractures, namely temporary fixation and therapeutic fixation.
Temporary fixation depends on on-site assistance. Assuming that the patient has serious open injury, severe hemorrhagic shock, and serious fracture dislocation, the rescue personnel will provide temporary external fixation support to maintain the stability of the pelvis, reduce secondary injuries, and correct the continuous aggravation of hemorrhagic loss on the scene. The therapeutic external fixation stent is used to correct the dislocation of the fracture through routine examination after admission, evaluation of the injury, and external fixation installation through treatment, maintain the relative stability of the fracture, create a very quiet environment for the fracture healing, and lay the foundation for the healing of the fracture. External fixation is an important method for pelvic fractures.
