Four misunderstandings in the planting of Artemisia annua L.

Since ancient times, Chenxiang has been a precious traditional Chinese medicine, royal offering, rare collection, five religious sacred objects and the most precious treasure of literati. However, due to the excessive demand by people, and even the depletion of resources, it has been established as a second-class rare and protected plant by the state. And vigorously promote the planting and development of Chenxiang.

Risk 1: not all incense trees will bear incense.

Usually, Chenxiang refers to the white wood incense tree, which belongs to the Daphne family. According to the distribution of Chenxiang resources on the earth, it is relatively concentrated in the tropical and subtropical regions of Southeast Asia. Among the similar plants in the world, there are four families and genera, but only the white wood incense tree of Daphneaceae can produce incense. White wood incense is subdivided, there are big leaves and leaflets, yellow and white, and the real production of high-quality incense is only the Hainan local incense that people often say in the industry.

According to ancient records, wild white wood incense trees once intertwined with branches for hundreds of miles, which can be said to be very luxuriant, but those who can bear incense "often have one or two in ten." most white wood incense trees can grow into towering trees, but the fact that they do not bear incense is no longer news. If the white wood incense tree wants to bear incense, it must undergo lightning strike, wind break, insect erosion and all kinds of man-made injury, or under the guidance of professional science and technology, it can bear incense quickly after it is injured.

Risk 2: not all incense seedlings meet the planting standards

Because the white wood incense tree is endangered and rare, its excellent female parent is extremely rare at present. The reporter learned that the requirements for planting seedlings of Chenxiang are very strict, and the seeds collected from high-quality mother trees over 12 years old must be selected before they can raise seedlings. After the seedlings come out, they need to be constantly selected and eliminated, and the seedlings refined in the field a year later can be given to growers for large-scale planting.

Risk 3: Chinan seedlings are not the same as Chenxiang.

Because of its different quality and incense parts, Chenxiang is subdivided into many grades and types in the industry, among which the most expensive one is Chinan Chenxiang, which is mainly divided into five categories: Bai Qinan, Lvqinan, Purple Chinan, Huang Qinan and Black Chinan. Because of the extremely high quality requirements and extremely rare, the current market price is almost all above 10,000 yuan per gram.

Risk 4: not any land can be planted with incense.

When recommending Chenxiang Miao, the owner of individual nursery said that Chenxiang can be planted in all places in Hainan, Guangdong, Guangxi, Yunnan and even Fujian. In fact, this is very irresponsible.

The best planting area is in the tropical and subtropical south, the best soil condition is red and yellow sandy soil, the best planting topography is not easy to form a gentle slope of stagnant water, and the characteristic of incense is most afraid of the problem of stagnant water. If the incense tree is planted in low-lying areas, it is very easy to lose its roots because of stagnant water. such examples abound.
