How to deal with the snowstorm:
1. Please try to stay indoors and don't go out.
2. If you are outdoors, stay away from billboards, temporary structures and old trees to avoid injury. When passing under a bridge, eaves, etc. , pay attention to observe or bypass, so as not to hurt people because the ice melts and falls off.
3. Non-motor vehicles should deflate the tires a little to increase the friction between the tires and the road.
4. Obey the traffic police command and obey the traffic guidance arrangement.
5. Pay attention to weather forecast and traffic information to avoid delays in travel due to the suspension or closure of airports, highways and ferry terminals.
6. Drive slowly and keep a distance from the car in front. The vehicle should slow down in advance before turning to avoid sudden braking. If possible, install snow chains and wear colored glasses.
7. After the traffic accident, clear signs should be set at the rear of the scene to prevent serial crashes.
8. If there is a power failure accident, it should be reported to the electric power department in time so as to deal with it quickly.
The hazard of snowstorm is 1. Blizzard causes cooling, which will cause freezing damage to fruit trees.
The research data show that the critical temperature of apple trees is -5℃ in late1October, -7℃ in early1October and-110,/kloc-0. 12 was -20℃ in mid-February, -23 ~-25℃ from late February to early February, -22℃ and-17℃ in mid-February, and-14℃ and-in late March, respectively. During these periods, if the temperature drops below the critical temperature in the case of heavy snow, it will cause different degrees of freezing damage to trees. Especially in early winter, trees lack cold-resistant exercise, and when they encounter heavy snow, the temperature drops suddenly, even if they are close to the above limit temperature, strong freezing damage will occur.
2. Aggravate the occurrence of diseases
During the melting period of ice and snow, due to the alternation of thawing and freezing, the hot and cold are uneven, and the yin and yang sides of fruit tree branches are unevenly heated, and the temperature difference between day and night is large, which is easy to cause the bark at the junction of yin and yang of branches to burst, leading to serious decay, rough skin and dry rot in the coming year. At the same time, the blizzard will also cause different degrees of freezing damage to unprotected scissors and saws, which will aggravate the occurrence of decay. For uncleaned orchards, deciduous leaves are covered with heavy snow, with high temperature and humidity, which is likely to lead to serious deciduous diseases in the early next year, mainly brown spot.
3. Pests are more harmful
In late autumn and early winter, if there is a blizzard, the ground is not frozen yet, which makes the ground temperature high, which is conducive to the safe wintering of underground wintering pests and leads to serious pests in the coming year.
4. Affect the annual output and quality of the next year.
If the temperature is high in late autumn and early winter, and then there is a sudden snowstorm, the temperature will drop greatly, and the sharp change of hot and cold weather is not conducive to the further differentiation and formation of apple flower buds, which will have an impact on the yield and quality of apples in the coming year.
Blizzard caused traffic disruption, which seriously affected the transportation and sales of Apple.
Blizzard caused traffic disruption, resulting in a large number of apples from producing areas can not be shipped normally, which seriously affected the early export and domestic sales of apples. In addition, due to the increase in transportation costs, the market price of apples will rise in the early stage, which will directly affect the consumption of apples. With the recovery of transportation in the later period, the pressure of apple sales has increased sharply, and it is possible that the price of apples will decrease, which will directly harm the interests of the majority of fruit farmers.
