Propagation method of thesium chinense seeds

Abstract

The invention provides a propagation method for obtaining of thesium chinense seeds through out-of-season planting of thesium chinense, which comprises the following steps: providing a planting area: arranging a greenhouse in an area with annual sunshine duration greater than or equal to 2400 h; sowing treatment: when the temperature in the greenhouse is 19-21 DEG C for multiple continuous days, covering the turned soil with a mixture containing shell-broken thesium chinense seeds, parasitic plant seeds and dry sand, applying a water-retaining agent, covering a seedling culture substrate, building a plastic arched shed, and covering the plastic arched shed with a sunshade net; after full seedlings emerge, removing the plastic arched shed and opening the sunshade net; growth control: keeping the temperature in the greenhouse at 15-25 DEG C, and in the yellow seedling stage and when thesium chinense seedlings are higher than 10 cm, performing intertilling and weeding, removing partial leaves of parasitic plants, watering and applying water flush fertilizer; removing flowering branches and part of leaves of the parasitic plants when the parasitic plants are in the stem extraction period and the thesium chinense is in the branching period, watering again and applying the water flush fertilizer; and finally, collecting naturally fallen mature fruits in a flower and fruit period to obtain the thesium chinense seeds.

Description

technical field [0001] The application belongs to the technical field of cultivation of Chinese medicinal materials, and in particular relates to a method for propagating thyme grass seeds. Background technique [0002] Thyme grass (Thesium chinense Turcz.) is a perennial semi-parasitic plant of the family Sandalaceae. Its dry whole herb is a common Chinese herbal medicine in my country. Most of the thyme grass is wild in the sunny grass or the middle and lower part of the field ridge in the mountains, rivers and valleys, generally in the plots with high humidity and good drainage. Therefore, the distribution of wild thyme grass with unique living environment is limited, mainly distributed in Henan, Guizhou, Hubei, Shanxi, Gansu and other remote mountainous areas. [0003] Wild annual thymegrass bears very little fruit that year, so the 1.5-year-old perennial thymegrass is mainly collected. Thingrass generally germinates from the end of February to early March of the secon...

Problems solved by technology

In recent years, the price of thymegrass medicinal materials has been rising continuously, resulting in rushing to harvest, resulting in a sharp decline in the maturity of thymegrass seeds on the plant, and the empty shell rate is between 30-50%. The seeds obtained after cleaning Further increase in cost

In addition, Thyme officinalis seeds have the characteristics of deep dormancy, low germination rate, and slow propagation speed, and are difficult to adapt to large-scale planting; therefore, solving the breeding of Thyme officinalis seeds has become one of the key factors for the wild variation of Thyme officinalis
