What are the customs of beginning of autumn in Jiangsu?

Entering the "slight cold" solar term, the cold climate will bring a lot of inconvenience to people's lives. In northern China, the temperature during this period is almost always below zero. So what's the date of 20 19 slight cold? Next, let's take a look at the old calendar book and explain it to everyone!

2065438+2009 Slight Cold Date: 2065438+200965438+1Saturday, October 5th, the 30th day of the Lunar New Year. This is the 23rd solar term among the 24 solar terms in the lunar calendar and the fifth solar term in winter, marking the official start of winter. When the sun reaches the longitude of 285, it marks the arrival of the coldest day of the year in China. According to China's meteorological data, slight cold is the lowest temperature solar term, and the temperature of great cold is only a few years lower than slight cold.

At the beginning of the cold solar term, the average temperature in Beijing is generally around -5, and the extreme minimum temperature is below-15. Northeast China is really a world of ice sculptures and jade carvings. This is the scene of winter. In the cold season, wheat, rape and other crops should pay attention to topdressing winter fertilizer, except in the southern region, while Hainan and most parts of South China mainly do well in water conservancy projects such as cold prevention, freezing prevention and accumulation of fertilizer.

Artificial mulching in winter is also an important measure to prevent freezing injury of agricultural and forestry crops on the basis of pouring frozen water, applying sufficient winter fertilizer and cultivating bacon before winter. When the cold wave turns into strong cold air, the harm of low temperature to rape can be effectively reduced by pouring dilute manure and removing plant ash. Vegetable fields cultivated in the open field can be sparsely spread on vegetable beds in winter as long-term plastic film, which will not affect the light, reduce the wind speed between vegetable plants, prevent geothermal loss, and achieve the effect of heat preservation and antifreeze. When the low temperature comes, the thickened plastic film will be temporarily covered and removed in time after the low temperature.

At this time, the vegetables in the greenhouse should get as much sunshine as possible. Even in the case of rain, snow and cold weather, mulch films such as straw curtains outside the greenhouse should not be left uncovered for many days, so as not to affect the normal photosynthesis of plants and cause nutrient deficiency. When the curtains are opened on a sunny day, the plants will wither and die. Alpine tea gardens, especially those vulnerable to the northwest cold wind, should be covered with straw, weeds or plastic films to prevent direct damage to leaves caused by wind-blown dead branches and sandstorms. After the snowfall, shake off the snow on the fruit branches as soon as possible to avoid the strong wind blowing off the branches.
