Spring
Also known as spring, it is the first season of the year in the northern hemisphere in March, April and May. In the southern hemisphere, it begins in November, as in Australia, where the climate is generally warm and moderate, and most of China's inland areas receive little rain. Everything sprouting, climate change, the first warm and cold.
Spring consists of six seasons:
Lichun: Lichun is the beginning of the meaning, Lichun is the beginning of spring. Since the Qin Dynasty, China has been to the spring as the beginning of spring. Lichun is divided astronomically, while in nature and in people's minds, spring is warmth, birdsong and flowers; spring is growth, plowing and sowing. In climatology, spring refers to the time when the average temperature is 10 ℃ to 22 ℃ (5 days for a wait).
When it comes to spring, people obviously feel the day is longer, the sun warmer. Temperature, sunshine, rainfall, this time often at the turning point of the year, tend to rise or increase. Small spring crop growth accelerate, rapeseed moss and wheat plucking when water consumption increases, should be timely watering and fertilizer, promote growth. Proverbs remind people of the spring rains, get up early and sleep late," the spring preparations for plowing has also begun. Although the spring, but most of South China is still very cold, "snow is too late for spring, so through the garden trees as flying flowers" scene. These climatic characteristics, in the arrangement of agricultural production should be taken into account. People often love to look for spring information where? That the willow on the head of the buds, "tender in gold soft in silk"; that the soil in the grass, waiting for the "spring breeze blowing again"; and in order to seize the new harvest in the fields of hard labor, people are using their hands to create a real spring.
Rain: the beginning of rainfall, the amount of rain gradually increased. The meaning of the rainy season is the beginning of rainfall and the gradual increase in the amount of rain. In the Yellow River Basin, where the twenty-four solar terms originate, the weather is cold before the rain, but it is difficult to hear the sound of rain when you see snowflakes flying. After the rain, the temperature generally rises above 0 ℃, with less snow and more rain. However, in the warm climate of the southern region, even in the middle of winter, rainfall is not rare. Most areas in the south of China during this period of time the average temperature is more than 10 ℃, peach and plum buds, cherry blossoms, indeed to enter the climate of spring. In addition to individual years, the frost period to this end. Grafting fruit trees, reforestation, it is time. South China following the winter dry, perennial spring drought, especially in western South China is "spring rain is as expensive as oil". Agriculture should pay attention to moisture conservation, timely watering to meet the wheat plucking pregnant spike, rapeseed moss blossom water critical period of water supply. Northwest plateau mountains are still in the dry season, the air temperature is small, wind speed, easy to forest fires. In addition, the cold wave invasion can cause strong cooling and blizzard, the old, weak, young animals are very harmful. All of these, should pay special attention to prevention.
Hibernation: Hibernation is the meaning of hiding. Hibernation refers to the first stirring of spring thunder, awakening the hibernation in the soil hibernating animals. To the hibernation, most of our country into the spring plowing busy season. Really: the season does not wait for people, a moment is worth a thousand pieces of gold. Most areas of the average temperature of the hibernation season is generally 12 ℃ to 14 ℃, more than 3 ℃ higher than the rainy season, is the fastest temperatures throughout the year. The number of hours of sunshine also has a relatively significant increase. However, because of the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. Southeast China Yangtze River Valley region, most years during the alarm temperature stabilized above 12 ℃, conducive to rice and corn sowing, the rest of the region is often more than three consecutive days of average daily temperature of 12 ℃ below the occurrence of cold weather, can not blindly early sowing. Although the hibernation temperature rises rapidly, but the increase in rainfall is limited. Central and northwestern South China during the hibernation rainfall totaled only about 10 millimeters, following the perennial winter dry, spring drought often began to show its head. At this time, wheat pregnant ears, rapeseed flowering are in the period of high water demand, sensitive to water requirements, spring drought often become an important factor affecting the yield of the spring. Tree planting should also take into account this climatic feature, after planting to be diligent in watering, and strive to improve the survival rate of saplings.
Vernal Equinox: The equinox is the meaning of equal division. Vernal equinox indicates the equal division of day and night. After the vernal equinox, most of the winter crops in southern China entered the spring growth stage. In central China, there is a "spring equinox wheat up, a moment worth a thousand words" of agricultural proverbs. Most parts of the south of the temperature continues to rise, but generally not as fast as the rain to the equinox period. late March average temperature in northern South China more than 13 ° C to 15 ° C, South China more than 15 ° C to 16 ° C. Most of the highlands have been snow melted ice. Most areas of the plateau has been snow melt ice, the average temperature of about 5 ℃ to 10 ℃. Most of the southern part of China and other valleys have the highest temperature, the average has reached about 18 ℃ to 20 ℃. South in addition to the edge of the mountainous areas, the average ten seven, eight years of average daily temperatures rose steadily to more than 12 ℃, conducive to rice, corn and other crops such as sowing, afforestation is also very suitable. However, before and after the vernal equinox in South China often have a stronger cold air invasion, the temperature dropped significantly, the lowest temperature can be as low as 5 ℃ below. Sometimes there is a small cold air followed by the formation of a sustained days of low temperature and rain, which is unfavorable to agricultural production. According to this feature, should make full use of the weather forecast, seize the cold end of the warm head timely sowing.
Qingming: the weather is clear, grass and trees flourish. Qingming is a festival that characterizes the weather and means clear weather and flourishing trees and grass. On the day of Qingming, there are folk customs such as trekking, cold food and tomb-sweeping.
Grain Rain: Rain produces all kinds of grains. Rainfall is sufficient and timely, cereal crops can thrive in the southern part of the rainy season, "poplar flowers fall out of the Zigui cries", willow wadding, azalea night cries, peonies spit stamens, cherry red ripe, natural scenery notice people: the time to the twilight of spring. At this time, the south of the temperature rises faster, the average temperature in late April, in addition to parts of northern and western South China, has reached 20 ℃ to 22 ℃, higher than the middle of 2 ℃ or more. South China's eastern part will often have one or two days of high temperatures of more than 30, so that people began to feel the heat. Low altitude valley area industry to enter the summer. South China spring temperatures higher climate characteristics, in favor of the spring crop cultivation measures to grasp early. Suitable for red camas planting temperature of 18 ℃ to 22 ℃, this time has been able to meet. The experience of the old dry areas of South China proved that the red camas in the rain early planting, can make the vine leaves before the drought seal box, enhance the drought-resistant ability, get high yield and stable yield.
