Answer: This is due to calcium deficiency caused by the lack of calcium in melon strips. The recent changes in temperature, and low temperature and cold weather cause the transportation and distribution of plant nutrients to be hindered, so this phenomenon is likely to occur. During the management process, pay attention to the insulation work and adjustment of plant growth during this period. In addition, adequate spraying of foliar fertilizers containing calcium and calcium supplementation through the leaves facilitates the above symptoms.

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.
