As the previous period consumes more nutrients, it is necessary to work on water and fertilizers, ie, watering once every 5 days, chasing dilute manure or diammonium (15 mus per mu), or applying dipping sauce cake (100 kilos per mu) to the ridges. . The medium-term can be used for quick-acting fertilizers, such as sulfo-ammonium (25 kg per mu) or ammonium nitrate (1.25 kg per mu), combined with foliar spray fertilizer. First, the mid-term farming. In the first time the third spike stays one gong (small frame variety). If the wolfberry produces strong growth, it will affect the pollination and fruit setting at the flowering stage. The growing point must be removed to promote the normal growth of the flower. The middle and large varieties remain in the 4-5 ear, the same management. Second, stay late. The emergence of small twigs in the adventitious section at the late growth stage of tomato. At this time, strong growth, dark green color, short internodes, and obvious flower buds can be selected for cultivation and other removal. Third, go to plant new. The original strain will be cut off with scissors at a distance of 5 cm from the ground, and then top-dressing (12.5 kg of mu with urea). In 5 days or so, a small sister-in-law grew up, and the selection was excellent. Disclaimer: Some articles in this website have been transferred from the Internet.

[Sample requirements] Vtm Sampling Tube With Swab,Disposable Collection Tube Of Virus Samples,Hi Media Vtm Kit,Amylase Sample Collection Tube Jilin Sinoscience Technology Co. LTD , https://www.contoryinstruments.com
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.
