First, grasp seedbed management
1, timely ventilation and dehumidification, weeding. After the green leaves of cotton seedlings turn green, they should be ventilated and dampened for 1-2 days in a timely manner to catch the warm and sunny weather, reduce the humidity on drying boards, and control the seedlings and weeds.
2, do a good job cotton tone. When picking up the true leaves, it is necessary to timely adjust the seedlings. Use a special biochemical preparation for seedbeds per mu of Daejeon standard seedbed to promote the strength of a bag of 1 kg of water and 2 kg of water, evenly sprayed to prevent the height of cotton seedlings and high seedlings to form. .
3, scientific thermostat. In the bed temperature adjustment, pay attention to two points: First, adhere to the ventilation without removing the film. Qimiao to proper increase of the bed temperature during the two true leaves, in order to speed up the speed of the leaf to promote early seedlings; the second true leaf after the flat exhibition, it is necessary to adhere to day and night ventilation, especially the strong resistance of insect-resistant cotton, should pay attention to the size of the vent Adjustment. The second is to prevent headless seedlings. After the true leaves are born, the cotton seedlings should be properly insulated, and in case of low-temperature weather, the ventilation openings should be closed in time to avoid cold damage and cause the growth point to shrink.
Second, insist on transplanting seedlings, timely transplanting
Many years of practice have proved that moving the seedlings can effectively shorten the seedling period after planting cotton seedlings, and awaken the seedlings early. Usually, the seedlings are transplanted 10-15 days before planting, and the seedlings are separated and the seedlings are placed in the middle of the bed. After the relocation, it is necessary to do a good job of "three supplements and one increase" in time to make up for soil, supplement fertilizer, supplement water, and increase bed temperature. On the basis of persisting in doing a good job of field preparation and fertilization, we will guarantee quality on May 10-15 and transplant them at appropriate times.
Third, do a good job in the cultivation of cotton field crops
Over the years, my county is still based on the composite planting types such as melon cotton, soybean cotton and corn cotton. Watermelon cultivation: First, continue to strengthen the seedbed management, cultivate healthy melon seedlings, the second is to do a good job in time hardening seedlings and field preparation, buried fertilizer, nursing care and other work. The field crops such as young soya beans and corn should be well managed after planting and planting, especially the work of pre-nursing and clearing and ditching.
Fourth, do a good job of live cotton production
There is still a certain area of ​​live cotton in the coastal area of ​​the county, and attention is paid to two things: First, we must timely prepare well-established fields for field preparation, fertilization, and clearing and ditch cultivation in the field; second, we must grasp the season (4) On and around the 25th of the month) and timely sowing of appropriate sensation, promotion of film live technology, and strive to win high production early.

The generic name of VTM Virus Sampling Tube is a single-use virus sampling tube, which is generally used for the detection and sampling of infectious pathogenic microorganisms in disease control departments and clinical departments. It is suitable for detection and sampling of influenza viruses (including general influenza, highly pathogenic viruses, H1N1 influenza virus, etc.), hand, foot and mouth virus, new coronavirus, measles and rubella and other types of viruses. VTM virus sampling tube can also be used for detection and sampling of Mycoplasma, Chlamydia and Ureaplasma urealyticum.
The virus and related samples in the VTM virus sampling tube should be stored and transported within 48 hours in a refrigerated state (2-8°C). Viruses and related samples can be stored for a long time in -80℃ environment or liquid nitrogen environment. The virus can maintain the activity of the virus in a lower temperature range, reduce the speed of virus decomposition, and improve the positive rate of virus isolation.
The VTM virus sampling tube is generally equipped with a disposable flocking swab. From the appearance point of view, the flocking swab is white and soft. Using this soft brush during the sampling process will make the user feel no foreign body, and it is suitable for different Partial sampling person. Moreover, the flocking swab is designed with a breaking point that conforms to the length of the sampling tube and the natural orifice of the human body, which is not only convenient for sampling but also convenient for transportation of the specimen.
