Clock solar terms

As the Mid-Autumn Festival approaches, people say that the harvest depends on sunny weather, and five old sayings know the details:

Because the sun returns along the Tropic of Cancer from summer to the future, but the heat emitted by the earth is less than the energy radiated by the sun, the surface temperature of the earth continues to rise, and the temperature climbs at the head. In the middle period, the temperature reaches its peak, followed by downhill, which is the final decline.

So the temperature in midsummer is the hottest. At this time, the crops in the field are growing vigorously, and many crops are in a critical period of transition from vegetative growth to reproductive growth. Rainfall affects the harvest of crops. Therefore, there is a saying among the people that it is sunny and rainy in midsummer, and five old sayings are well known.

One is rainy, and the other is Ridomi.

This proverb means that if there is rain in midsummer, our crops in Man Cang will be harvested and packed, because in midsummer, the temperature outside is high, the transpiration of the earth is large, and the ground is seriously dry. At this time, the early rice is about to mature and harvest, and the growth of rice cannot be separated from water.

Especially in the filling and fruiting period, water is essential, otherwise, the shell will shrink and the yield will drop seriously. At this time, mid-season rice and summer corn are in the transition period from vegetative growth to reproductive growth, which requires a lot of water. If it rains a few times in midsummer, rice and corn will grow well and get a bumper harvest, and the granary will be full of food.

Second, rain in the middle is a good year, and there are abundant grains everywhere.

This proverb means that if it rains in midsummer, the crops will get a bumper harvest. During midsummer, for the northern region, spring corn is in the filling and fruiting period, while for the southern region, it is the early rice maturity period. This is the key period of grain formation. High temperature and drought will lead to premature aging and 1000-grain weight reduction.

So at this time, I am most afraid of no rain. As the saying goes, "Five days without rain and light drought, ten days without rain and heavy drought, and thirty days without rain and smoke" is a summer drought, which is a disaster for crops. Appropriate rain in the middle can promote grouting and increase 1000-grain weight, so the whole grain is abundant.

Three, head in the rain, forty-five days without cattle.

This proverb means that it rained a few days ago in alto, so cows are not needed for the next forty-five days, because it rained in alto and it rained for the next forty-five days.

Because of the heavy rain, the fields are wet and the cows can't plow the fields. Forty-five days later, it was the heat. As soon as the heat was over, the crops began to harvest. In dog days, because of abundant rain, crops grow vigorously, and in the heat, the ears of grain are full and the fields are bumper.

Fourth, there is no shortage of rain in the first two days, and there will be snow on the ninth day.

This proverb means that it rains nine days before and snows nine days after, so it snows nine days before and nine days after, because solar terms are formulated according to the laws of solar motion, and they have symmetrical properties, so the temperature is hot in rainy days and it will be cold in the last nine days. The hotter summer is, the colder winter is. Because there is no shortage of rain in rainy days, crops grow well, which is a good omen, while cold winter and abundant snow are also good harvest years.

Fifth, the rain blocks the door, and the widow marries early.

This proverb means that there is too much rain in the middle section, which causes floods, so the widow will marry herself ahead of time, because there are many thunderstorms in the middle section, not only frequent typhoons, but also natural disasters such as hail and floods.

In ancient times, crop failure would kill people. Widows lead a hard life. When they encounter bad years, they have to marry themselves to avoid starvation. Therefore, moderate rain will lead to serious crop yield reduction, which indicates a disaster year.

To sum up, midsummer is approaching, and the outdoor temperature will continue to rise. The so-called "light summer, steamed and cooked thoroughly", but at this time, crops grow vigorously, and suitable rain can promote crop yield, so there is a saying among the people that midsummer rain knows the harvest, and the above five proverbs can tell the details.
