Artificial planting method of wild conyza blinii Levl.

Abstract

Disclosed is an artificial planting method of wild conyza blinii Levl.. The method comprises the following steps of (1) seedling raising, wherein seed soaking in warm water and seed soaking in clear water are involved in seed treatment; seeds are put into the warm water at 30-35 DEG C for stirring, fine sandy soil is mixed in during sowing, and stirring is uniformly conducted to make the soil in aloose state; the seeds are soaked for 1-2 days under sunlight illumination, and during sowing, the seeds with water are uniformly stirred; in the sowing stage, spring sowing is conducted from the Beginning of Spring to the Rain Water, and autumn sowing is conducted from August to October; the sowing amount is 1-2 kg per mu; (2) transplanting; (3) field management; (4) disease and pest control; (5) seed collection and reservation, wherein during seed collection, each to-be-collected plant flower is sleeved with a bag-shaped container and gently patted, so that mature seeds are patted into thebag; during seed reservation, in the best growing environment area, a seed field is selected and established through a crop rotation mode; (6) harvesting and processing, wherein from June to Septemberevery year, harvesting is conducted from an early blooming period to a full blooming period, and the harvesting portion is 3-5 cm from the ground. By means of the improved seedling raising technology, the seed germination rate is increased; the best harvesting and seed collection time is determined, and the seed collection and reservation method is perfected; the yield and single-plant saponin content of conyza blinii Levl. plants are increased.

Description

technical field [0001] The invention relates to the technical field of planting Chinese herbal medicines, in particular to a method for artificially planting wild gentian. Background technique [0002] Gentiana, also known as bitter wormwood, is a plant of the genus Baijucao in the Asteraceae family. It is an annual or biennial herb depending on the growth environment.

AI Technical Summary

Problems solved by technology

For a long time, since Golden Gentiana is a wild natural resource, it is scattered in the Panxi area of ​​Sichuan. From the end of the 1970s to the 1980s, more than 10 tons of wild Golden Gentiana could be harvested every year, and in the 1990s, 3-5 tons could be harvested. Since the beginning of the century, less than 1,000 kilograms have been purchased each year, and the quantity has become less and less, and the resources have been severely damaged, which has seriously restricted the marketing of the superior product of gentian saponin tablets, and its annual production volume cannot meet the local market demand.
