Embodiment 1

[0033] Effects of water temperature during seed soaking on the germination rate of Gentiana gentiana seeds.

[0034] ① Method: One day before sowing, take the seeds of Gentiana gentiana and place them at 5°C, 10°C, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C, 50°C, 55°C, Stir in water at 60°C; the control group directly enters the subsequent steps without soaking in water.

[0035] Before sowing, mix in 24-80 mesh dry fine sand, the weight ratio of seeds to fine sand is 1:10, stir evenly to become loose, and evenly sprinkle in the seedling tray.

[0036] ② Results: Continuously observed for 20 days, counted the seed germination rate, the results are shown in Table 1.

[0037] The germination rate (unit: %) when table 1 different water temperature soaks seed

[0038]

[0039] The experimental results show that when soaking the seeds of Gentiana gentiana, the germination rate of the seeds is the highest when the soaking temperature is between 30°C and 35°C.

Embodiment 2

[0041] Effect of fine sand particle size on germination rate.

[0042] The fine sandy soil selected in this example is to clean the river sand first, and dry it at ≥ 120° C. for more than 3 hours, and cool it to room temperature for later use. Weed seeds etc. may be mixed in the river sand. In this embodiment, the seeds of Golden Gentiana are extremely small. If there are weeds etc. during germination, it will seriously affect the germination of Golden Gentiana seeds. Therefore, the river sand in the present invention is all selected at ≥ Drying at 120°C for more than 3 hours, the clean river sand after cooling.

[0043] ① Method: One day before sowing, take the seeds of Gentiana gentiana, place them in water at 30°C and stir them respectively, and after standing for one day, sow them in a seedling tray placed in a greenhouse at a temperature of 20°C, keeping the soil moist during the period.

[0044] Before sowing, mix the fine sandy soil in the above steps of 10 mesh, 24 mesh...

Embodiment 3

[0050] The effect of the weight ratio of seeds and sand on the germination rate of seeds

[0051] ① Method: One day before sowing, take the seeds of Gentiana gentiana, place them in water at 30°C and stir them respectively, the weight ratio of water to seeds is 5:1, after standing for 1 day, sow them in soil at a temperature of 25°C, and keep the soil moist. Before sowing, mix the weight ratio of soil and gentian grass seeds in groups into 2:1, 5:1, 10:1, 15:1, 20:1, 25:1 dry fine sand, and stir evenly to become loose; Sprinkle evenly in the seedling tray.

[0052] ② Results: Continuously observed for 20 days, counted the seed germination rate, the results are shown in Table 3.

[0053] The impact of table 3 seed and fine sand weight ratio on germination rate (%)

[0054]

[0055] The experimental results showed that when the ratio of seeds to fine sand was 1:5-1:15, the germination rate of Gentiana seeds was basically stable.

Abstract

The invention discloses a Conyza blinii seed breeding and seedling culture method. On the premise of deeply researching the growth and development characteristics and proper growth conditions of Conyza blinii, the cultivation of Conyza blinii seedlings is mainly researched, and a reasonable seedling cultivation method is formulated. By means of the seedling cultivation method, the seedling rate ofConyza blinii seeds can reach about 50%, endangered wild Conyza blinii is changed into artificial planting, and long-term influences on the ecological environment and social and economic benefits canbe generated.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a method for artificially cultivating wild domesticated golden gentian medicinal seedlings. Background technique [0002] Golden gentian, also known as bitter wormwood, ikruzi, fish gall grass, absinthe, Jinzhi gentiana, short-legged wormwood, and bear bile, is a biennial herb of the genus Asteraceae genus, mainly in a wild state, distributed It is located in the sparse forest area at an altitude of 1100-2600 meters in the mountainous areas of southwest Sichuan and northwestern Yunnan. Golden gentian is used as a whole herb as medicine. It has the functions of clearing heat and resolving phlegm, relieving cough and asthma, detoxifying dampness, cooling blood and stopping bleeding. It is often used to treat cough due to lung heat, asthma with excessive phlegm, sore throat, aphtha, damp-heat jaundice, epistaxis, and blood in the stool , uterine bleedin...
