Apricot tree autumn caught two items
The nutrients required for the formation of apricot flower organisers were completed by the accumulation of tree bodies in the autumn of the previous year. Therefore, the autumn management plays a decisive role in the flowering and fruit setting of Hunchun. Autumn tube of apricot should grasp the following two items:
First, thinning and short apricot trees are strong and happy trees. Their growth is very strong, it is easy to form a competitive growth and the resulting parts are shifted outwards. This is very unfavorable for the formation of strong flowers and results, so it should be in the autumn The result tree is mainly sparse, and the pruning method based on short stabs is adopted for pumping large branches and depressing tree heights to promote new branches from the lower part and the introverts to form short fruit branches and bouquet-like fruit branches. Of course, attention should be paid to maintaining the main branches of the reserved branches to open the light path evenly, and the individual branches that can be left standing upright can be pulled, dropped, or otherwise supported and changed. Skirts, sick branches, and dense branches can be removed together.
Second, fertilization and irrigation in the fall of apricot garden can be quickly applied 50-100 kg of nitrogen fertilizer or 30-50 kg of urea, and apply phosphorus, potash appropriate amount, the planting of trees, trees can be applied around the nitrogen, phosphorus, potassium three Mixed fertilizer 3-5 kilograms per plant, after the application of rain is good, if the drought is serious drought, can be in August-September and strive to water. But pay attention to the roots under the tree can not be long bubble, bubble for a long time easy to hurt the root.
[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.
