Inappropriate use of chicken manure as a base fertilizer can lead to root damage. Some greenhouses experienced root burning due to the presence of flaming alkali in the manure. Additionally, excessive application of chemical fertilizers can also cause root burn. After some cucumber plants were damaged, the seedlings began to grow unevenly. To manage this issue, it is recommended to apply well-composted organic fertilizers early and in appropriate amounts. During the growth period of cucumbers, it's beneficial to flush in biological bacterial fertilizers such as Jianzhibao or Haozhen series products to support healthy development.
Uneven ground in the greenhouse can result in inconsistent water distribution. Areas that are higher tend to receive less water, while lower areas may become overly saturated. Moreover, many farmers add fertilizer during watering, which can further intensify uneven growth. To address this, the ground should be leveled properly, and watering should be done carefully to ensure all seedlings receive equal amounts. It’s also important to prevent excessive water accumulation in the greenhouse to avoid root suffocation, which can lead to stunted or uneven growth.
Root-knot nematodes are another common problem in greenhouses. These pests affect the roots differently, with some plants suffering more severe damage than others, leading to uneven growth in cucumber crops. A recommended control method is to apply 1.8% abamectin diluted at 2000–3000 times, with about 200 ml of solution per plant, directly to the root zone.
During planting, seedlings of different sizes can sometimes occur. This often happens when vegetable growers have spare seedlings available from earlier stages. However, if serious diseases occur at the seedling stage, there might not be enough healthy replacements, and using subpar seedlings could worsen the problem. To avoid this, seedlings should be selected and planted evenly. Spraying a diluted solution of Naphthalene Acetic Acid (No. 1) at 800 times can help promote uniform growth and reduce disparities among the plants.
Mini Locking Plate
The mini locking system can be used for the fixation of ossicles and small bone fragments, osteotomy, arthrodesis, and replantation and reconstruction of ossicles and small bone fragments.
It is composed of micro locking plate 1.5mm/2.0mm/2.4mm/2.7mm series, covering a variety of plate types and a wide range of indications. The plates are all anatomical design, which reduces the need for shaping and helps to reduce the workload of surgeons. Low profile and countersunk screw design can reduce soft tissue injury. Matching orthopedic screws self-tapping design, convenient implantation, screw plum design, reduce screw hexagonal sliding teeth. The composite hole design can not only realize the compression of the fracture end, but also can be used as a locking internal orthopedic fixation frame. Part of the reconstruction structure is convenient for the surgeon to tailor the implant according to the actual situation in the reoperation, and increase the flexibility of the operation. Its indications are mainly phalanx, metacarpal, scaphoid and other carpal bones, ulnar styloid process and capitulum, radial head and styloid process fracture fixation. The 1.5mm orthopedic implants titanium system is mainly used for the middle and proximal phalanx, the 2.0mm orthopedic plates system for the metacarpal bones, the 2.4mm implant locking plate system for the first metacarpal bones and carpal bones, and the 2.7mm mini plate system is mainly used for the distal ulna and radius. According to the clinical research, the micro-locking plate internal fixation in the treatment of multiple comminuted metacarpal fractures can effectively achieve the anatomical reduction and healing required by the clinic. The patients have good postoperative healing, and the functional recovery of the affected limb is good during the postoperative follow-up. It has good clinical effect and can be further promoted and applied.
