Defense Guide

This time the cold air intensity is strong, the temperature drop is large, and the temperature is low, mainly due to the influence of low temperature freezing and strong winds. Recommendations:

1. The water supply and gas supply department should pay attention to the anti-freeze and heat preservation work of the water supply and gas supply system to prevent pipes, water meters, etc. from freezing and cracking;

2. The agricultural department should pay attention to taking measures Measures should be taken to prevent strong winds, freeze and keep warm in facility agriculture, tea, fruit trees, open-field crops, livestock sheds, etc.;

3. Public security, housing construction, municipal administration, transportation, maritime affairs, health, emergency, power supply, etc. All departments pay attention to prevention of low temperature freezing and strong winds.

Farming Suggestions

It is necessary to strengthen ditch clearing and draining of winter wheat, rapeseed, green manure and fruit trees, tea trees, etc. in low-lying areas to prevent stagnant water from freezing and aggravating frost damage; For the harvesting and marketing of field-produced vegetables, we will speed up the harvesting and marketing of vegetables in the field that are significantly affected by the cold wave, and cover and insulate those that cannot be marketed in time to reduce the risk of freezing.

In terms of agricultural facilities, it is necessary to improve and reinforce the scaffolding facilities, tighten the lamination ropes, and add columns and tie rods to strengthen the safety hazards, especially those that are old and over-long and over-wide. The scaffolding must bear the capacity to prevent the scaffolding from collapsing or strong winds from lifting the membrane to aggravate freezing damage. During periods of cold air influence, anti-freezing and warmth preservation, ventilation and dehumidification, and lightening and disease prevention must be carried out.

It is necessary to do a good job in cold-proofing and insulating the poultry and livestock sheds of poultry and livestock farmers, and increase the lighting time.

In terms of aquaculture, it is necessary to deepen the water level of low-water ponds and ensure that the effective water depth is more than 1.5 meters as much as possible; check aeration equipment and make timely ice breaks to prevent hypoxia; temporarily place crab storage boxes In deep water, prevent frostbite or death in shallow water; suspend net fishing and pay attention to the safety of pond patrols.
