Cucumber "return to melon" refers to the melon of the main cranberry at the end of harvest and knots on the side branches of the plant. The correct identification and use of the “keep melon†feature of cucumber in production can promote vine-side nectar, which can increase yield and increase yield. How to promote "return"?
After the cucumber enters the result period, the fertilizer should be replenished timely to keep the plant robust. During the growth of the main melon, the leaves were sprayed with fertilizer, 0.2% urea plus 0.3% potassium dihydrogen phosphate, and sprayed once every 5-7 days. This is the key to promoting "returning melon."
When the number of main vines is reduced, the amount of watering is reduced. Generally, water is poured once every 10-15 days to promote the growth of "melon". During the expansion of "returning melons", fertilizer and watering should be promptly applied to promote the growth of "returning melons" and increase production. After sitting in the “returned melonâ€, 20 kg of urea was applied per acre, and water was poured every 3-4 days. In the early stage of cucumber, the main vines are mainly guarana. For the melons on the upper side of the plants, the melons on the side vines should be left after two leaves are left on the melons. When the main vine reaches the top of the shed, the main vines will be picked in time to promote the melons. "Growth.
[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.
