The origin and custom of the solar term of Mangrove in 2018

Mount seed is the ninth solar term of 24 solar terms and the third solar term since summer. The arrival of the solar term of grain in ear indicates that all crops will be planted and the agriculture will be busy. What is the date of mangrove planting in 2018? What is the origin of the solar term of the grain in the air? What's the custom of the solar term of the mountain seed? Let's get to know with Xiaobian.

The seed in the mangrove is the ninth solar term in the 24 solar terms of the lunar calendar, when the sun reaches 75 degrees.

The word "mang" refers to the harvest of awn plants such as wheat, and the word "mang" refers to the planting season of millet crops. The homophony of the word 'Mangchong' indicates that all crops are 'busy planting'. Therefore, 'mangrove' is also called 'busy planting', which is also called 'busy planting' among farmers. The arrival of 'grain in the field' indicates that farmers have begun their busy field life. Zuohe River's "grain in the mang" poem called its weather and busy farming situation as "sunny hot unloading clothes, Meiyu Xiaoxiao rising Liutang.". Nanling is surrounded by Hezhuang day, and wheat harvest is busy on both sides of the river. '

The origin of the solar term of the grain planting

In ancient China, mangrove species were divided into three periods: first, the growth of Mantis; second, the sound of Peng; third, the silence of anti tongue. In this solar term, the eggs of praying mantis in late autumn of last year broke their shells and gave birth to small praying mantis because they felt the birth of Yin Qi; the Shrike that liked Yin began to appear in the branches and felt Yin and sang; on the contrary, the anti tongue bird that could learn other birds' singing stopped singing because it sensed the emergence of Yin Qi.

As a solar term reflecting the phenomenon of agricultural phenology, mirabilis is a symbol of the maturity of crops with awns such as wheat. Till now, the wheat harvest season in Sichuan Basin has passed, and the transplanting of middle rice and sweet potato is coming to an end. In most areas, the medium-sized rice has entered the stage of returning to green, and its seedlings are green and vigorous. The poem that the east wind dyed 3000 hectares and the broken Heron flew everywhere vividly described the beautiful scenery of the field at that time. In the season of grain in the basin, the medium-sized rice that has not yet been transplanted should be planted as soon as possible; if it is delayed again, the growth period of rice will be shortened due to the increase of temperature, and the growth period will be vulnerable to drought and diseases and insect pests, so the yield will not be high. The transplanting of sweet potato should be done before the summer solstice at the latest. If the transplanting of sweet potato is too late, not only the impact of drought will be aggravated, but also the temperature will drop when autumn comes, which is not conducive to the expansion of potato blocks, and the yield will be significantly reduced. There is a saying in the proverb of farming that the grain crops are busy planting.

It's a busy solar term. In Shaanxi, Gansu and Ningxia, the grain in the summer is busy growing and the grain in the summer is pregnant. In Guangdong, it is planted under the grain in the summer. In Jiangxi Province, there is no rice seedling in the first three days and no rice seedling in the second three days. In Guizhou, there is no need to plant any more than the grain. Fujian is the edge of the grain, good indica, grain, good waxy. Jiangsu is a treasure planted in the mirabilis and a grass planted in the summer solstice. Shanxi is a kind of mirabilite, all kinds of species. Grain in the Mang and millet in the rush. Sichuan and Shaanxi are busy planting before and after the grain in the field. It can be seen from the above farm work that, to the mangrove planting Festival, China is busy planting from south to north, and the busy farming season has reached a climax.

'in April, the grain is planted in the front, in May, the grain is planted in the back'. That is to say, in April in North China, the wheat is mature, but in May, the grain is not mature. Why? This is the same as the peach blossom blooming in February Qingming and the spring Qingming in March, which are caused by the lunar calendar algorithm. According to the lunar calendar, a year is actually 354 or 355 days. This is 10-11 days less than the number of days the earth has to go around the sun, so a leap of three years (sometimes two years) is necessary to supplement the short number of days. In leap month, the solar term is either advanced or delayed, so the seed in winter is sometimes in April, sometimes in May. Farmers in our country know that because of the early spring in April, the solar term is pushed forward, so the crops are planted early. If we want to plant them before the solar term, in June, the crops will be planted after the solar term. This is a scientific planting method with a dead solar term and a living method.

The "grain in the mang" is a kind of gramineous plant with the shortest growth period. The early variety can mature in 80 days, and even the late variety can mature in no more than 100 days. It is the last crop planted in the autumn. Therefore, in North China, when there is no rain in the morning and other crops miss the solar term, they are often used to make up for it, and good harvests can also be obtained. Under normal circumstances, when Miscanthus is planted, the seed Valley can also be mature, but the growth period of millet is longer than that of Miscanthus, and it may suffer from frost damage. Therefore, it is said that "Miscanthus is planted in a hurry."
