Reasons for Autumn Flowering of Cymbidium

The article "Huilan Autumn flowering is not easy to discuss with Mr. Hu Yimin" published by Mr. Zhang Shanghua in Huainan City has a deep feeling. Since it is a controversial article, he puts together his own views, and his point of view is mainly based on the evolution process of wild Yilan distribution in this province.

Anhui has a special geomorphology, with great differences in topography, high in the south and low in the north. In the territory, there are mainly the Yangtze River and Huaihe River crossing the province, with different climates, distinct seasons, warm and humid in the south and dry and cold in the north. The distribution of wild Magnolia is uneven due to specific geographical location and different climatic environment. The large-scale orchid-producing areas are located in the south of the Yangtze River and the southwest of the Jianghuai watershed. In these places, there are more magnolia in the dense jungle, but less in spring orchid. Mr. Li Renyun, an expert on orchid cultivation in our province, has a clear overview of the distribution of wild Huilan in Anhui Province in his book Lanyun, so I will not repeat it any more. Today, we mainly discuss the causes of autumn flowering caused by Huilan ecological environment and climatic factors, which are described from three different aspects below.

First, the autumn flowering of Huilan is purely an occasional product in a specific environment, and there is no universal consensus at present. On the one hand, the autumn flowering of Cymbidium is first attributed to the evolution of natural climate anomalies, although the autumn flowering of Cymbidium is rare and rare, and it belongs to the abnormal category in the abnormal specific environment. Although the wild magnolia resources in the province are quite rich, they are not generally different. This is inseparable from the natural factors such as different geomorphology, climatic environment, vegetation rainfall and so on formed by the complex geological structure in the specific geographical location of the province. On the other hand, the Yangtze River and the Huaihe River form the south. The three major blocks of North and Central China result in a large climate-specific contrast. The south of the Yangtze River belongs to Nanshan District, the north of the Huaihe River belongs to the plain of northern Anhui, and the one in the middle is called Jianghuai. The mountainous climate in southern Anhui is mild and humid and rich in vegetation contains certain wild Magnolia resources. Huaibei Plain has a vast and boundless climate, harsh, dry and little rain. There are no Huilan resources at all. Only the climate between Jianghuai and Huaihe River is warm and humid, the land is fertile, and the Jianghuai watershed is in the southwest of Dabie.

The mountain area is the main distribution area of Huilan, where the ecological conditions adapt to the breeding of a large number of food orchids. The average elevation of the mountain is about 500 meters above sea level, and there are more Huilan in the jungle bamboo forest. Shucheng County, Huoshan County, Jinzhai County and Lu'an City are all old areas, there are primeval forests in many places, the rich environmental and ecological resources of vegetation have not been artificially destroyed, and many wild Yilan thrive in a large number of pine bamboo forests. Autumn blossoms occasionally occur when climate anomalies are encountered in the evolution of nature. At the same time, the annual winter and spring flower market Huilan mainly comes from these mountainous areas, which is that a certain number of strange flowers appear every year due to the specific environment and superior geographical location. Wild Cymbidium here is not only easy to raise but also adaptable, and it is easy to blossom in extensive management. Local mountain farmers say that Huilan's autumn flowering is a sign of warm winter and symbolizes the tillering state of flower buds in the growing season. Huilan sometimes blossoms twice a year in spring and autumn. It does not belong to universality but to the category of occasional irregularity. There are not all Huilan resources in Jianghuai. There are no wild Huilan in Shou County, Huoqiu County and the north of Lu'an City to the north of the watershed, which are all caused by the special geomorphology of the Jianghuai watershed. Moreover, it is more difficult to see wild Cymbidium in the vast areas north of Huainan and Bengbu.

Second, why Huilan blossoms in autumn today arouses people's interest. With the increasing craze of raising orchids today and the development of novelty-hunting mentality, I feel that Huilan blossoms in the contrast season is rare and rare. Didn't wild Italian orchids blossom in the age of abnormal climate before liberation? It just didn't attract as much attention at that time as it is today. The ancient Huilan blossoms in autumn rather than today's discovery. Today, people raise orchids and love orchids to explore that Huilan blossoms in autumn is purely caused by natural factors.

Huilan is a wild plant for many years, and it is a flower with strong tolerance to drought and cold. Unlike other plants, its bulb is small but its germination rate is high, and its thick leaf and root system has the advantages of tenacious and natural life. It can rely on good natural ecology in a specific environment and promote the possibility of secondary expansion and flowering of Huilan in a short time under the sufficient condition of Rain Water. It shows that Huilan autumn flowering is inseparable from the inevitable factors of abnormal climate products, which is in line with Huilan's own law. When any plant encounters abnormal seasonal changes in the process of growth and evolution, there are many phenomena of blooming and bearing secondary fruit in the second stubble, which is a reflection of the inevitable law of abnormal growth in natural ecological evolution.

Third, human factors may also promote the possibility of Huilan blooming in autumn. Huilan is planted in the pot to strengthen moderate water and fertilizer management, which can make the temporarily dormant Huilan blossom quickly in the flower bud tiller, which requires biennial strong grass. Unconventional flowering is purely special and does not conform to the regular range of Huilan's normal flowering period. However, the size of the country can not rule out the possibility of autumn flowering in other provinces of Huilan. Huilan in nature blossoms in autumn, and mountain farmers often find in the mountains in autumn that, as they say, "thousands of trees wither in the cold winter months, wild animals have no grass to eat, and the green leaves of orchid leaves exposed in the mountains are most easily eaten by wild animals. They eat half a piece of orchid leaves and leave half stubble without affecting germination and growth at all. Spring recovery of all things to promote rapid germination of flower buds steaming, after some favorable weather time contains breeding budding and blooming. Shannon's words are reasonable. Artificial adjustment of florescence is not satisfactory, such as selecting Zhuang Shihui orchid in early spring, breaking off flower buds and planting in pots, sufficient water and fertilizer happens to blossom in autumn, only occasional flower bud variation is still unstable in the coming year. Therefore, the discussion of Huilan autumn flowering can not rule out the abnormal results of natural factors affecting the change and evolution of ecological materials. In recent years, there are many orchid-raising patients in our city who love Huilan, and some specialize in Huilan.

The door domesticated Huilan potted plants. after several years of cultivation, people occasionally put flowers every autumn, and there are also a lot of flowers twice a year. We all agree that the strong fragrance of magnolia is easier to raise than Chunlan, and the leaves are elegant and elegant, which embellishes the advantages of elegance. Break the traditional consciousness of raising orchids in the past, it is difficult to raise Huilan, but Huilan can't blossom in pots. There is little difference in climate between the Dabie Mountains in the southwest of the Jianghuai watershed and the mountains in southern Anhui, so there are a lot of wild Huilan resources in both places, and Mr. Ming Yimin is mainly engaged in Anhui-style bonsai research, which is mainly based on the mountains in southern Anhui. It is not surprising to occasionally see Huilan blossom in autumn. Moreover, Mr. Zhang Shanghua has a point, ignoring the fact that there are no wild Huilan resources in the north of Shouxian County. At present, the whole country

The fragrance of orchids can be found everywhere, so we can not rule out the phenomenon that people who love orchids bloom in autumn in potted plants. Nowadays, the technology of Alanzhilan is much higher than the traditional level, and it is normal for Huilan to blossom in autumn occasionally in the process of cultivation. Scientific development Today botanists solve the flowering law of flowers by scientific means to meet the market demand, and flowers will not be far away as people want.

There are thousands of plants in the world, and it is not surprising that the evolution of Huilan is abnormally blooming. The above discussion is mainly based on natural conditions. There are many explanations on climate effects, different landforms, ecological differences and so on. This article is only for discussion and does not dare to be the same as others.
