It is understood that the Guangxi Agriculture Department gives guidance on antifreeze and cold resistance of sugar cane:
　  First, do a good job in the ideological work of the masses, widely mobilize sugarcane farmers to seize the raw material sugarcane, and prioritize the collection of sugar cane that is seriously affected by the disaster, so as to continue to slot and not squeeze.
   Second, the harvested Sugan cane land is covered with mulch or sugarcane leaves to ensure cold, to ensure that the growth point, axillary buds are not frozen, and frozen.
Third, the sugar cane breeding base and the sugarcane land reserved for planting, it is necessary to use fumigation insulation or spraying cold-resistant agents to prevent cold insulation.
   Fourth, strengthen the management of sugarcane field in autumn and winter, and adopt heat preservation measures such as fumigation, drenching, spraying foliar fertilizer and spreading grass ash. After the weather has warmed up, the new plant cane will resume its vitality, and a full-fledged organic fertilizer and quick-acting fertilizer will be applied as a seedling fertilizer to promote its rapid recovery.
   Fifth, according to the disaster situation of various places, when the group is slashed, more sugarcane seeds will be kept to ensure the need for replanting and new planting sugarcane.
   6. The sugar industry departments and sugar-making enterprises in various localities organize the work of cutting and crushing, and repair the damaged sugarcane road as soon as possible to ensure the normal production order in the whole season.
Venous cannula is also a deep venous puncture catheter. The method is to select the appropriate puncture site and insert the needle under the skin, and insert the needle with negative pressure until the dark red blood is absorbed, indicating that the needle has entered the vein, and the guide wire is inserted. Withdraw the puncture needle to leave the guide wire in the blood vessel, and then insert the venous catheter that needs to be indwelled along the guide wire, then exit the guide wire, inject diluted heparin saline and fix the catheter, the deep venous catheterization is completed. The veins for puncture and catheterization are usually selected clinically, including the subclavian vein, internal jugular vein, and femoral vein. After the puncture catheter is indwelled, attention must be paid to the care of the puncture site to avoid infection with thrombus or catheter falling off.
