Spring pomegranate tree pruning

A: Pomegranate tree spring pruning is carried out after germination to the bud stage before flowering, usually from mid-April to May. At this stage, the ratio of fruit branches is mainly adjusted: the excessive small fruit branches or the resulting mother branches are removed, so that the fruit branch ratio is reasonable. Sparse buds and thin flowers: From the bud to the full bloom period, the bell-shaped flowers are wiped off, leaving the tubular flowers and gourd-like normal flowers. Sparse the pests and branches: pruning the pomegranate in the spring, and also cutting the branches of the pests, which can be carried out simultaneously with the buds and thinning. Wiping and de-emergence: At the same time of buds and sparse flowers, the dense sprouts and stems of the dense buds and the stems and buds of the main branches are removed, which is conducive to ventilation and light transmission and saves nutrition.

Vtm Sampling Tube With Swab

[Sample requirements]
The collected nasopharyngeal swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.

[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.
3. The specific sampling methods are as follows:
a) Nasal swab: Gently insert the swab head into the nasal palate, stay for a while and then slowly turn to exit. Wipe the other nostril with another swab, immerse the swab head in the sampling solution, and discard the tail.

b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab, also immerse the swab head in the sampling solution, and discard the tail.

4. Quickly put the swab into the sampling tube.
5. Break the part of the sampling swab higher than the sampling tube, and tighten the tube cover.
6. Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 2°C to 8°C.

[Explanation of test results]
After the sample is collected, the sampling solution turns slightly yellow, which will not affect the nucleic acid test result.

[Limitations of the test method]
1. For samples that are seriously contaminated due to improper storage after collection, the final test results will be affected.
2. If the sample is not stored at the specified temperature, the final test result will be affected.
