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.

Embodiment 1

[0043] The present embodiment provides a kind of artificial planting method of wild wild golden gentian, comprising the following steps:

[0044] (1) Seedlings can be sown in open boxes on seedbeds, or can be sown in nutrient trays in greenhouses.

[0045] a. Sowing time: autumn sowing (August ~ October), spring sowing (beginning of spring ~ rain).

[0046] b. Seedbed land arrangement for plastic sheds: choose sheltered, sunny, slightly higher terrain, loose soil; close to water sources, capable of irrigation and drainage, and convenient for management as seedbed land. Turn the kang soil 15 days before sowing, and apply an appropriate amount of organic fertilizer, per mu (667m 2 ) Spread 1000Kg of decomposed compost or manure, sterilize the seedbed soil with 500-1000 times carbendazim or dexamethasone, and then open the box along the north-south direction, with a width of 1.1m.

[0047] c. Preparation of nursery soil in nutrient tray greenhouse: One week before seedling cult...

Embodiment 2

[0075] The dry matter weight and saponin content of plants at different growth stages were measured to determine the best harvesting time.

[0076] (1) Dry matter accumulation and distribution are shown in Table 1. From the perspective of growth cycle, the dry matter accumulation rate of Gentiana gentiana at seedling stage is very slow. As shown in ﹟11 in Table 1, the seedling height was 6.0cm at 55 days, the leaf age was 9.0 leaves, the dry weight per plant was only 0.057g, and the dry matter accumulation rate per plant was 0.001g / day. At this time, dry matter was mainly stored in leaves as structural or non-structural carbohydrates, accounting for 85.96%. The growth time of ﹟12 was 79 days, the dry weight per plant was 0.148g, the dry matter accumulation rate per plant was 0.002g / day, and the distribution ratio of dry matter in leaves was lower than that of ﹟11, which was 75.6%. From the beginning of bolting, the accumulation of dry matter accelerated, and the growth time o...

Embodiment 3

[0089] In order to improve the germination rate of seeds, we conducted seed treatment trials to determine the best seed treatment method. The germination process of seeds is divided into three stages: imbibition, germination and germination. Normally (the temperature is around 20°C and the water is saturated), 2 days after sowing, the seeds will absorb water up to 150% of their own weight, the seed epidermis will flatten, and the wrinkles will disappear. After imbibition, the seed radicle elongates, breaks through the seed coat, and exposes the white root tip, which is the completion of the germination stage. This stage takes about 3 days. After that, the embryo continues to grow, and the germ breaks through the seed coat, and the germination process is completed, which takes about 6 days in total.

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. The medicinal parts are the stems, branches, leaves, and flowers of the aboveground parts. Gentiana is distributed in the Panxi region of Sichuan, Liangshan Prefecture, the Anning Valley of Panzhihua City, the Yalong River Valley, the Jinsha River Valley, and parts of Yunnan and Guizhou. [0003] Due to the good clinical therapeutic effects of Gentiana saponin tablets, the market demand continues to increase. 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 ...
