Embodiment 1

[0040] Embodiment 1: Cutting propagation of Jinyun Scutellaria baicalensis one

[0041] The place of the experiment was Lizilin, Jingangbei Village, Beibei District, Chongqing City, in June 2018, and the area of ​​the nursery was 0.2 mu.

[0042] (1) Seedling cultivation: Remove the weeds in the nursery one year before cutting, and deeply plow the land at a depth of 25-40cm. The soil should be exposed to sunlight to disinfect and sterilize the soil and reduce the occurrence of pests and diseases. Carry out 1 more plowing in the following year. When plowing, break the soil clods, rake the nursery ground, and spray 1000 times carbendazim solution made from 50% carbendazim to thoroughly disinfect the nursery soil. The seedbed is made into a raised and low bed with a "U"-shaped groove in the middle. The width of the seedbed is 1.2m and the length is 3m. The "U"-shaped mouth of the middle groove is 20cm wide and 15cm deep. The "V" groove with a moment of 10cm, the inclined surface...

[0054] Example 3: Cutting propagation of Jinyun Scutellaria baicalensis III

[0055] The experiment site was Lizilin, Jingangbei Village, Beibei District, Chongqing City, in October 2018, with a nursery area of ​​0.5 mu.

[0056] (1) Seedling cultivation: Remove the weeds in the nursery one year before cutting, and deeply plow the land at a depth of 25-40cm. The soil should be exposed to sunlight to disinfect and sterilize the soil and reduce the occurrence of pests and diseases. Carry out 1 more plowing in the following year. When plowing, break the soil clods, rake the nursery ground, and spray 1000 times carbendazim solution made from 50% carbendazim to thoroughly disinfect the nursery soil. The seedbed is made into a raised and low bed with a "U"-shaped groove in the middle. The seedbed is 1.2m wide and 5m long. The "U"-shaped mouth of the middle groove is 20cm wide and 15cm deep. The "V" groove with a moment of 10cm, the inclined surface of the "V" groove is 8cm, and the...

Abstract

The invention discloses a cutting propagation and field return method of the endangered medicinal plant Scutellaria baicalensis, belonging to the technical field of tree seedling propagation. The propagation technology includes the following steps: Seedbed: remove weeds in the nursery one year before cutting, deep plow 25-40cm, In the next year, plow again and spray carbendazim solution for disinfection. The seedbed will be made into a raised and low bed with a "U"-shaped groove in the middle, and a "V"-shaped groove will be made on the seedbed; and subsequent cuttings, cuttings, Management and protection, seedling hardening, and field return steps. The purpose of the present invention is to provide the cutting propagation and field return method of the endangered medicinal plant Scutellaria baicalensis, to solve the problem of low reproductive efficiency of Scutellaria baicalensis and improve the survival rate, and to further expand the suitable growth area to expand the population and scale of Scutellaria baicalensis .

Description

technical field [0001] The invention relates to the technical field of jinyun scutellaria baicalensis propagation, in particular to a cutting propagation and field regression method of the endangered medicinal plant jinyun scutellaria baicalensis. Background technique [0002] Scutellaria tsinyunensis C.Y.Wu&S.Chow is a perennial herb of the genus Scutellaria in the Labiatae family. It is a unique plant in Jinyun Mountain and has been listed as a very small population by the State Forestry and Grass Administration for protection. In the natural environment, Jinyun Scutellaria baicalensis is distributed in the shape of "islands" isolated from each other. The distance between the populations is relatively far, and there is reproductive isolation. Each population occupies a narrow space, and the distribution range is further shrinking, and the number of individuals continues to decrease. , with characteristics of endangered plants. Jinyun Scutellaria baicalensis has good antib...
