Embodiment 1

[0024] From May 15th to October 15th, 2009, 5 notch-type plants of Atractylodes atractylodis were randomly selected in the Agricultural Science and Technology Park of Zhenjiang City, Jiangsu Province. A 60 cm semi-enclosed transparent organic resin tube was buried in the root of each Atractylodes atractylodes plant, and the outer wall of each transparent organic resin tube was close to the root system of Atractylodes atractylodes, inclined at 45° to the ground. The open end of the resin tube is used as the upper nozzle, and the upper nozzle is 12 cm above the ground. Cover the upper nozzle with opaque film paper to prevent light and rainwater from entering the transparent resin tube and affecting the measurement of the root length.

[0025] Half a month after the transparent resin tube was buried, the film paper was uncovered, and the scanning head of the root system automatic monitoring system was inserted into the transparent resin tube, and the scanning head was used to fi...

Embodiment 3

[0036] From May 15 to October 15, 2009, 5 plants of Atractylodes brevilanceolus were randomly selected in the Agricultural Science and Technology Park of Zhenjiang City, Jiangsu Province. A 60 cm semi-enclosed transparent organic resin tube was buried in the root of each Atractylodes atractylodes plant, and the outer wall of each transparent organic resin tube was close to the root system of Atractylodes atractylodes, inclined at 45° to the ground. The open end of the resin tube is used as the upper nozzle, and the upper nozzle is 12 cm above the ground.

Abstract

The invention discloses a method for determining the harvest time of Atractylis lancea by utilizing the changes of the root growing amount. The method is as follows: in the mid-May, five strains belonging to the same type of Atractylis lancea are selected randomly, a transparent organic resin pipe matched with a root system automatic monitoring system is buried in the root system part of each strain; a scanning head is inserted in each transparent organic resin pipe on the 15th day to obtain three pictures for the root system of each strain; then the same operations are performed every 15 days, namely a cycle, as least 10 cycles are performed; then the average root system length of the five strains in the n-th cycle is calculated; the average root system length in the n-th cycle minus theaverage root system length in the (n-1)th cycle is the actual added value of the root system of Atractylis lancea, mapping is performed according to the added value to the detection period to obtain the growth peak rhythm of the root system, and the cycle before the second peak of root growth is determined to be the optimum harvest time. Therefore, Atractylis lancea is harvested timely, the geo-herbalism of Atractylis lancea can be kept and the method can also be used to determine the harvest times of other Chinese medicinal herbs of which roots and stems are used as medicines.

Description

technical field [0001] The invention relates to a method for determining the harvest period of atractylodes atractylodes by using the change of root growth, and belongs to the field of medicinal plant biotechnology. Background technique [0002] The study of the law of plant growth and development can provide a theoretical basis for the selection and breeding of excellent plant varieties. For a long time, people generally use conventional experience to judge the harvest period of plants, which is feasible for plants with fruits as economic products, but there are serious deficiencies for plants with harvested rhizomes. [0003] Atractylodes atractylodis is a perennial herb of Compositae. Its dry rhizome can be used as medicine. It has a medicinal history of more than 2,000 years in my country. It has been highly praised in medical works of all dynasties. Its history is recorded in "Shen Nong's Herbal Classic", Can dry dampness and invigorate the spleen, dispel wind and cold....
