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, which then dry out, curl, become brittle, and fall off easily. Additionally, the tips of the branches may appear scorched, with the leaves turning brown and dying. This disease can interfere with flowering and fruit set during the blooming stage, resulting in small, thin dates and premature fruit drop during the early fruit development phase. In severe cases, the entire tree may lose all its leaves, which weakens the tree's vitality and significantly reduces the yield.
The occurrence of this disease is often linked to weakened tree health after pruning or improper care, leading to poor resistance and increased susceptibility to infection. Moreover, the recent combination of moderate temperatures and high humidity has created ideal conditions for the disease to spread rapidly.
To manage the disease effectively, it is recommended to start spraying treatments from early July. A solution of 500 times diluted Fungin (anti-fukuning) mixed with 100-140 units of agricultural streptomycin should be applied every 10 days. Alternatively, a mixture of 15% bacterial agent WP at 800 times dilution and 3% polyoxin (1000 times dilution) can also be used. In severe cases, spraying three times may be necessary to control the disease.
In addition to chemical treatments, it's important to improve overall orchard management. Ensuring proper fertilization and irrigation, avoiding waterlogging during the rainy season, and maintaining good air circulation around the roots can further help reduce the risk of disease occurrence. By combining these preventive measures with timely spraying, farmers can better protect their jujube trees and ensure healthier harvests.
Lower limb Locking Plate
Lower Limb Locking plate is a kind of implant fracture orthopedics with locking thread holes.
The lower limb locking plate allows the bone to bind to the plate more firmly, so that the reduced limb is more stable. Locking plates were first used in spine and maxillofacial surgery 20 years ago to stabilize fractures while reducing extensive dissection and damage to soft tissues. When the threaded hole in the locking plate is screwed in by a screw with a threaded head, the plate becomes an Angle fixing device. It can have both locking and non-locking holes for different screws to be screwed in. Any plate that can be screwed into an Angle fixed (stable) screw or bolt is essentially a locking plate.
Locking plate system does not rely on bone friction to achieve connection, but completely depends on the interlocking structure of the plate itself. A certain gap between the plate and the bone surface can be left, which can eliminate the adverse effect of heavy pressure contact between the plate and bone, and greatly improve the blood supply and the growth and recovery of the periosteum. The main biomechanical difference from conventional plates is that the latter relies on friction at the bone-plate interface to accomplish plate compression on bone. Stability is maintained by an angularly stable interface between the screw and the plate. Because the locking internal fixator has a stable integrity, the pull-out force of the locking screw is much higher than that of the ordinary screw. It is difficult for a single screw to be pulled out or broken unless all the surrounding screws are pulled out or broken.
