Polygonatum polygonatum (Polygonatum polygonatum vulgaris), a precious herb widely used in traditional Chinese medicine, has attracted attention for its rich nutritional and medicinal properties. In the northern region of China, due to its unique climate and soil conditions, a number of excellent yellow essence planting bases have been bred.
First of all, we came to Fei County, Linyi City, Shandong Province. It is one of the important bases for the cultivation of yellow essence in the north. Fei County is located in the warm temperate semi-humid monsoon climate zone, with four distinct seasons, rain and heat in the same season, which provides suitable climatic conditions for the growth of Polygonatum polygonatum vulgaris. In addition, the soil of Fei County is mainly brown soil and brown soil, which is rich in organic matter and trace elements, which is conducive to the development of the root system of Polygonatum polygonatum and the accumulation of nutrients. Therefore, the development of yellow essence planting industry here is relatively mature, and the yield and quality are in the forefront of the country.
Next, we turn our attention to Xixia County, Nanyang City, Henan Province. Xixia County is located in the southwest of Henan, belongs to the transition zone from the first belt to the warm temperate zone, the climate is mild, the rainfall is abundant, the average annual precipitation can reach 800-1000 mm, such climatic conditions provide sufficient water for the growth of Polygonatum polygonatum **. At the same time, the soil of Xixia County is mainly yellow-brown soil and sandy loam, with deep soil layer and high fertility, which is very suitable for the cultivation of Polygonatum polygonatum vulgaris. Therefore, Xixia County is also known as one of the ideal planting places for Polygonatum polygonatum
Then, we went north to Ning'an County, Mudanjiang City, Heilongjiang Province. Ning'an County is located in the southeast of Heilongjiang Province, belonging to the cold temperate monsoon climate zone, with a cool climate, severe cold winters and cool summers. Although such climatic conditions are challenging for many crops, they are just right for Polygonatum polygonatum. Because Polygonatum prefers a cold environment, it is cold tolerant and can grow normally at lower temperatures. In addition, the soil in Ning'an County is loose and has good drainage, which is conducive to preventing the occurrence of root diseases of Polygonatum polygonatum and thus ensuring the healthy growth of Polygonatum polygonatum root.
Finally, we came to Jiaohe City, Jilin City, Jilin Province. Jiaohe City is located in the eastern part of Jilin Province, which belongs to the temperate humid climate zone, with a humid climate and four distinct seasons. The soil here is dominated by black soil and dark brown soil, rich in organic matter and minerals, which provide sufficient nutrients for the growth of Polygonatum polygonatum Therefore, Jiaohe City has also become an important planting base of Polygonatum polygonatum
The above is only a part of the northern yellow essence planting base, in fact, there are many other places that are also actively carrying out yellow essence cultivation. However, no matter where it is planted, it needs to be scientifically and reasonably planned and managed according to the actual local conditions, such as climate, soil, water source and other factors, in order to ensure the high quality and high yield of Polygonatum polygonatum.
In general, the success of the northern yellow essence planting base is not only due to the unique natural conditions, but also inseparable from the hard work and wisdom innovation of scientific researchers and farmers. With the progress of science and technology and the growth of market demand, we have reason to believe that the northern yellow essence planting industry will usher in a broader development prospect.
