Fertilizer and water management after peach harvest
After the peach tree bears fruit, it consumes a lot of nutrients. If the technical management can be strengthened in time after the peach is harvested, the nutrient accumulation of the tree body can be increased, the tree vigor can be restored as soon as possible, and good flower buds can be formed. Favorable conditions. After the peach is harvested, apply a quick-acting fertilizer in time. At the early fruiting stage, 0.25 kg of urea was applied to each plant, and at the adult tree, 0.5 kg of urea was applied. The amount of nitrogen fertilizer must be controlled to prevent the branches from becoming long and affecting the differentiation of flower buds. Combined with the prevention and control of plant diseases and insect pests, foliar fertilization was carried out, and 0.3% to 0.5% potassium dihydrogen phosphate solution was used from August to September at 15-day intervals. From September to October, a basic fertilizer is applied in combination with deep tillage and expansion, with fully rotted farm organic fertilizer as the main supplement and ternary compound fertilizer as the supplement. In the early fruiting period, each plant uses 50-100 kg of organic fertilizer and 0.5-1 kg of ternary compound fertilizer; the adult tree uses 100-200 kg of organic fertilizer per plant and 1-2 kg of ternary compound fertilizer. The fertilization method can be circular groove or radial groove, and the depth of fertilization is 30-50 cm. After the peach is harvested, there is usually a lot of rainwater, so there is no need to water. If the drought period is too long, water can be used to supplement the moisture as appropriate. In the rainy season, drainage and waterlogging, plowing and weeding should be conducted to prevent soil compaction. Disclaimer: Some articles of this website are 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.
