There are still nine days is Xiaoman solar term. As the second solar term in summer, what's the climate change in Xiaoman? The following is a detailed introduction to the climate change in Xiaoman solar term. Come and have a look!
What are the climate changes in Xiaoman
Xiaoman refers to wheat and other mature crops with milk filling and full grain. The agricultural proverbs in Sichuan Basin give Xiaoman a new meaning: "Xiaoman is dissatisfied, but he can't stop thinking about the ridge"; Xiaoman is dissatisfied, but he doesn't care about the seed. ". The term "man" is used to describe the surplus and shortage of rain. It is pointed out that if there is not enough water in the field during the period of "Xiao man", the ridge of the field may be cracked, and even rice can not be planted during the period of "mang". Because 'Xiaoman is planting seedlings at the beginning of summer' and 'seedlings run to Xiaoman Valley for Autumn', Xiaoman is the season suitable for rice planting. Whether the summer drought in the basin is serious or not is directly related to the planting area of rice, and the planting time is closely related to the yield of rice.
Xiaoman: fight nails. The Yellow meridian of the sun is 60 & deg;. Starting from Xiaoman, summer crops such as barley and winter wheat have already borne fruit and full grains, but they are not yet mature, so they are called Xiaoman.
Generally speaking, if the cold air from the north can penetrate into the south of China at this time, the warm and humid air flow in the south is also strong. If so, it is very easy to cause heavy rain or torrential rain in South China. Therefore, the later stage of Xiaoman solar term is often the tense stage of flood control in these areas.
In the middle and lower reaches of the Yangtze River: 'Xiaoman doesn't come down, Huangmei is less',' Xiaoman doesn't have rain, mangrove seeds don't have water '
For the middle and lower reaches of the Yangtze River, if there is less rainfall at this stage, it may be that the subtropical high over the Pacific Ocean is weaker and located to the south, which means that there may be less rainfall in the Huangmei season. Therefore, there is a folk saying that 'Xiaoman doesn't come down, Huangmei is less';' Xiaoman has no rain, mang has no water '.
The middle and lower reaches of the Yellow River: "if Xiaoman is dissatisfied, wheat is in danger"
Xiaoman solar term, the middle and lower reaches of the Yellow River and other areas also spread such a saying: Xiaoman dissatisfaction, wheat has a risk. This risk means that wheat is just entering the stage of milk ripening at this time, and it is very vulnerable to the damage of dry hot wind, resulting in insufficient grain filling, withered seeds and reduced yield. There are many ways to prevent dry hot wind, such as building shelterbelt, spraying chemicals and so on are very effective measures.
Jiangnan region: "Xiaoman is too busy to know him when he drives three cars."
The three cars here refer to waterwheel, tanker and silk car. At this time, the crops in the farmland need plenty of water, so the farmers are busy turning the water on the water cart; the harvested rapeseed is waiting for the farmers to beat, making the fragrant rapeseed oil; the farm work in the field can't be delayed. But the silkworm babies at home should also be taken care of carefully. Before and after Xiaoman, the silkworm will begin to cocoon. The silkworm farmers are busy shaking the silk cart to reeling (SAO).
It is recorded in qingjialu that "when Xiaoman first came, the silkworm wife cooked cocoons, reeled silk and operated day and night.". It can be seen that in ancient times, new silk was about to go on the market when the solar term was over, and the silk market was about to turn prosperous. All the silkworm farmers and silk merchants were full of expectations, waiting for the harvest day to come soon.
In addition, during the Xiaoman solar term, the Jiangnan area is often full of rivers and lakes. If you are dissatisfied with it, it will be a year of drought and less rain. There are many proverbs in this respect, such as the saying that "Xiaoman is dissatisfied, there is no water to wash dishes" in Anhui, Jiangxi and Hubei provinces; the agricultural saying that "Xiaoman is dissatisfied, and the fields are broken" in Guangxi, Sichuan and Guizhou provinces; and the saying that "Xiaoman is dissatisfied, and the plow and harrow are high" in Sichuan Province. The word "man" here does not mean that crops are full of grains, but that there is more rain.
