Chemical control measures for Chinese cabbage soft rot

For the prevention and treatment of the disease, it is possible to use the streptomycin sulfate or agricultural streptomycin 1000-1300 times solution; or the neomycin 1300 times solution for spraying; or 50% dexamethasone water 100 times solution; or 70% dikesone wettable powder 800-1000 times liquid; or 60% bactericidal wet powder 500-600 times liquid; or 40% bacterial spirit (CT fungicide) 1 piece (0.5g) plus water 4kg; or Antibacterial agent "401" 500 times solution. Focus on the surface or petiole of the soft rot strain and its surrounding vegetable plants, so that the liquid can flow into the cabbage heart, and the effect is better.

IECEx Approved Coriolis Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.

The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.

The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
