The potted white orchid, when placed in the north, may look beautiful at first, but after several years of growth, the lower parts of its main and side branches often become bare and leafless. This unattractive condition is known among gardeners as “going pants,†which not only looks unsightly but can also weaken the plant’s overall health. To address this issue, a full pruning is recommended, ideally during mid to late May. This process encourages the growth of new buds and lateral buds, helping to reshape the tree crown by reducing the dominance of older branches.
By cutting back all the branches, the orchid is stimulated to produce new foliage from the axillary buds. After pruning, the number of lateral branches can increase by 3 to 4 times, with each original branch potentially giving rise to 3 to 4 new side shoots. As a result, the canopy becomes more compact and lush, while also increasing the number of flowering sites, leading to a more vibrant and healthy plant.
When performing this type of crown renewal, it's essential to make the cut just above a lateral bud—ideally about 0.6 cm above the top bud—to avoid leaving a stub that could lead to rot or poor regrowth. Additionally, when selecting which buds to keep, it's important to choose those that are growing on the outer part of the tree. This ensures that the new branches grow outward, maintaining a balanced and attractive shape. If the selected buds are inside the canopy, the new growth may cross over, causing a messy appearance and disrupting the tree’s structure.
After pruning, it's advisable to protect the cut areas from drying out. One effective method is to cover the cuts with a small piece of plastic film or apply a layer of pruning paint. This helps prevent dry rot and promotes better healing, ensuring that the new buds have the best chance to sprout and thrive. With proper care and timing, this pruning technique can revitalize the orchid and restore its beauty for years to come.
Vtm Test Kit
The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.
The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
