â‘ Sparse branches Cut branches or branches from the base of the branches. Over-dense auxiliary branches can be strong and weak; upright branches on the back of the main and auxiliary branches; strong branches at the top of the canopy are too strong, or too many branches when the crown is shaped, etc. for thinning.
â‘¡Short cut some branches from the middle of the branches. The purpose is to promote multiple shoots, renew the fruiting branches, and rejuvenate the weakened trees.
â‘¢Pulling branches Pull the branches horizontally. The purpose is to allow the canopy to open, the sunlight is transparent, the tree vigor is relaxed, the flower bud differentiation is promoted, the fruiting rate is increased, and the fruiting is early.
â‘£ Ring cutting Use a knife to cut the branches on a certain part in a circle, reaching the xylem. The purpose is to allow the young and middle-grown young bayberry trees that grow too vigorously and do not easily form flower buds. After ring cutting, the photosynthesis products can be retained in the upper part to promote the formation of flower buds and improve the fruiting rate and yield. Therefore, its time is suitable for June.
1. Pruning time Summer pruning time is from June to July. This stage can prun off large branches and strong branches that disturb the tree shape.
2. Reasonable load will be reasonably thinned according to the situation of the fruiting branches of bayberry. Generally, there are 2 long fruit branches, 1-2 medium fruit branches, 1 short fruit branch, and 1 weak fruit branch. Each fruit, to ensure the appropriate amount of fruit.
3. Plant conditioning agent to prevent fruit fall 30-15 days before fruit picking, foliar spray the relevant agent 1-2 times, every 15 days interval, inhibit the formation of abscisic acid, effectively reduce fruit fall.
4. Pruning after picking The bayberry is pruned reasonably after picking to avoid shading in the orchard, poor ventilation and light transmission, sawing off some of the middle upright large branches, dwarf plants, and cutting off the cross branches, dense branches, disease and insect branches, etc.

â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
