Recently, he has been receiving continuous consultations from young farmers regarding the issue of jujube trees losing their leaves. After conducting an on-site investigation, it was determined that the problem is caused by jujube charred leaf disease. The main symptoms include water-soaked leaves, dryness, curled and brittle foliage, premature yellowing, and easy leaf drop. Additionally, the tips of the branches may appear scorched, with the upper parts of the tree turning dry and dead. This disease can interfere with flowering and fruit set during the blooming stage, resulting in small, thin dates and fruit drop during the early fruit development phase. In severe cases, the entire tree may lose all its leaves, which negatively affects the tree's overall health and yield.
The occurrence of this disease is often linked to weak tree vitality after pruning, poor resistance, and increased susceptibility to infection. Moreover, the recent moderate temperatures combined with high humidity have created favorable conditions for the disease to spread. To manage the condition effectively, it is recommended to begin spraying treatments starting from early July. A solution of 500 times diluted "Fukuning" mixed with 100-140 units of agricultural streptomycin should be applied every 10 days. Alternatively, a mixture of 15% bacterial agent WP diluted at 800 times and 3% polyoxin (diluted at 1000 times) can also be used. In severe cases, three applications may be necessary to control the disease effectively.
In addition to chemical treatments, it is important to improve overall orchard management. Proper fertilization and irrigation practices should be maintained. During the rainy season, care should be taken to prevent waterlogging, ensuring good root aeration and ventilation. These measures can significantly reduce the likelihood of disease occurrence and help maintain the long-term health of the jujube trees.
Knee Joint
Total knee replacement is for patients with severe pain and/or severe joint disability due to osteoarthritis, post-traumatic arthritis, rheumatoid arthritis, or previous implant failure.
The total knee joint system consists of femoral condylar , tibial tray,tibial insert and patella.The femoral condylar and tibia tray are made of Co-Cr-Mo in accordance with the quality standards.Tibial insert and patella are made of UHMWPE containing PBHP antioxidants.
The revision knee system is suitable for cemented total knee replacement in patients with severe joint pain or severe disability due to osteoarthritis, post-traumatic arthritis, or rheumatoid arthritis, moderate knee varus, varus, or flexion deformity of the knee, avascular necrosis of the femoral condyle, previous failed knee replacement, osteotomy, or other knee surgery.
Total knee arthroplasty (TKA) is a practical and effective method for the treatment of serious knee arthropathy. However, attention should be paid to the selection of indications, the correction of joint internal and external inversion and flexion deformity, and the correct placement of tibial prosthesis to reduce the loosening of tibial prosthesis. At the same time, early functional exercise should be carried out to reduce postoperative complications. Total knee arthroplasty (TKR) provides an effective treatment for patients with severe knee arthrosis.
