Plastic trimming
After the apricot tree is harvested, open the branches and open the branches to ease the vigor of the tree and promote flower formation; the new shoots are pinched and twisted twice to promote the branching and cultivate the branch group. The fruiting branches that are significantly weakened and drooped after the result should be properly retracted. For the extraordinarily long branches that sprout in the canopy, if there is room for growth, take measures such as topping and twisting the tips to control their vegetative growth; for the extraordinarily long branches without growth space, timely remove them. At the same time, cut off dead branches, split branches, diseased and insect branches, cross branches, overlapping branches, and weak branches in the canopy to reduce nutrient consumption of the tree body and improve the ventilation and light conditions of the tree body to facilitate the formation of high-quality flower buds.
Fertilizer management
After harvesting, it should be combined with weeding and loosening the soil in the whole garden. Generally, the depth of cultivating is about 10 cm. Combine basal fertilizer and deep plowing before falling leaves, with a depth of 30-40 cm.
Fertilizer should be applied as soon as possible after harvest, especially for trees with weak tree vigor and more fruit in the year, and fertilization should be timely to make up for the consumption of nutrients in the tree. A quick-acting fertilizer was applied to the apricot trees immediately after the fruit was picked, and 0.5 kg of urea was applied to each adult apricot tree, and then watered. Combined with spraying, foliar spraying and spraying a mixture of 0.3% potassium dihydrogen phosphate and 0.2% urea can increase the nutrient accumulation of the tree and increase the number and quality of flower buds. From late August to early October, base fertilizer is applied, mainly high-quality farmyard manure, mixed with a small amount of phosphorus and potassium fertilizer. Generally, 30-50 kg of farmyard manure and 0.3-0.5 kg of superphosphate shall be applied to the first-fruit tree of 5 to 6 years old; 70-100 kg of farmyard manure and 0.5-1 kg of superphosphate shall be applied to each plant in the full fruit period. Watering immediately afterwards can increase the nutrient level of the tree body and keep the tree vigorous after harvest to ensure the next year's yield.
After harvesting, watering in time for the first time can ensure the normal differentiation of flower buds and the growth, aging and maturity of branches. If it is rainy during this period, do not water it. At the same time, attention should be paid to drainage. In the rainy season, if there is accumulated water, it should be removed in time to prevent the apricot tree from being infected by waterlogging and affecting the growth and development of the tree. Pour the frozen water, and in places where conditions permit, pour the water thoroughly before freezing to ensure that the apricot trees can survive the winter safely.
Pest Control
Apricot trees are often harmed by pests and diseases after picking fruits, and spraying should be used to protect the leaves and increase nutrient accumulation in the tree according to the actual situation. Timely control of aphids, red spiders, sky caterpillars, boat-shaped caterpillars, apricot disease, bacterial perforation and other pests.

There are mainly the following parts: 1. Sampling swab with disposable sterile plastic rod/rayon head 2. Sterile sampling tube containing 3ml of virus maintenance solution (gentamicin and amphotericin B are selected to better inhibit the fungus in the sample. Avoid the human sensitization reaction that may be caused by penicillin in the traditional sampling solution.) In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc. Intended to use 1. It is used for monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments. It is suitable for sampling of influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses. It is also used for sampling of Mycoplasma, Chlamydia, Ureaplasma, etc. 2. It is used to transport nasopharyngeal swab samples or tissue samples from specific parts from the sampling site to the testing laboratory for PCR extraction and testing. 3. It is used to preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture. The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict, and three requirements must be met at the same time: 1. The safety of transportation. Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations. 2. The security of preservation. Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations. 3. The validity of the sample. Make sure that the sampling tube itself will not have a toxic effect on the sample.
