The top ten meritorious service is a kind of traditional Chinese medicine type plant, which problems should be paid attention to in breeding the top ten merit? Next, I will introduce it to you in detail.

The morphological characteristics of the Top Ten achievements

Leaves Obovate to Obovate-lanceolate; florescence July-September; racemes 4-10 clustered, flowers yellow, inflorescences 3-7 cm long; pedicels 2-2.5 mm long; fruit September-November; berries globose, 4-6 mm in diameter, purplish black, with a layer of white outside.

Ten growth habits of hard work

Ten Gonglao is a warm temperate plant, with a strong cold resistance, not resistant to summer heat. Like warm and humid climate, strong, shade-resistant, avoid hot sun exposure, have a certain degree of cold resistance, but also relatively resistant to drought. Most of them grow under damp valleys and forests in the country of origin and belong to negative plants. Like well-drained acid humus, extremely alkali-resistant, afraid of waterlogging.

The mode of reproduction of the top ten credits

Sowing and raising seedlings

The top ten efforts in the wild are getting less and less, and this method is used to propagate a large number of seedlings in the garden nursery. The ten major achievements in sowing and raising seedlings are mainly to grasp the time of seed collection, the method of seed treatment, the thickness of sowing cover and the careful management after sowing.

In May, when the fruit is ripe, the oval berries can be picked, slightly stacked, mixed with fine sand, rubbed, or soaked in warm water to rinse off the peel, pulp and empty seeds, then remove the full seeds, dry and put them in a cloth bag, hang them in a cool and ventilated dry place for storage, store the seeds in low temperature sand to the following spring after winter, sow in March, cover the soil with 1-2cm after sowing, sow in half-shade after soaking water, and germinate for about a month. It can also be sowed directly after the completion of seed treatment, sowed in a semi-shady environment, sowed in the seedbed and covered with soil 3~5cm.

The optimum temperature for seed germination is 15-25 ℃, and the seeds can germinate and emerge in about 50 days. The seedbed should be flat, the soil grains should be finely broken, and ditches should be opened to sow seeds. In the same year, the height of seedlings can generally reach 8~10cm, a little cold protection during the overwintering period, leaving the bed for another year, the second year can be extended transplanting. Seedlings usually take 4-5 years to blossom and bear fruit.

Barge in

A small amount of reproduction can be done by the method of insertion. Hardwood cuttings should be carried out from February to March and semi-hardwood branches from May to June. Cut 1-2-year-old strong branches, cut off the ear segments that grow about 15cm, and insert them into the sandy soil seedbed to keep the seedbed moist. In May, they began to build a shed for shade, spray every sunny day, and rooting after sowing for about 2 months. Shoot cuttings can be carried out in the rainy season, select the branches that have been enriched in the same year, or use one-year-old branches to grow 15~20cm, the seedbed temperature can be controlled at 25: 30 ℃, it can take root after one month, and the survival rate can reach more than 90%. When the branches are treated with rooting agent, the rooting rate can reach more than 90%.

Ramet

Ramet can be carried out from mid-October to mid-November or from late February to late March, or combined with changing pots in spring. Dig up the clump-like plants of the ground, or remove the large clump of potted plants from the flowerpot, cut or tear them from the weak combination of the rhizome, with 2-3 stems and a part of intact roots in each clump, and plant or pot the leaves slightly after pruning the leaves.

Rapid propagation

With the expansion of the production scale of proprietary Chinese medicine, the demand for the top ten plants is increasing day by day, and the wild one is facing a serious shortage of resources. The top ten merit usually uses asexual reproduction, so the rapid propagation of the top ten by means of biotechnology and the realization of large-scale production will be an effective way to solve this contradiction, which has a certain reference value for the study of artificial reproduction of the top ten meritories. it will provide a basic theoretical basis for the rapid propagation of the top ten.

The efficacy and function of the top ten credits:

1. Antibacterial activity: 25% of the decoction of the ten herbs of broad leaves has a slight inhibitory effect on Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa in vitro.

2. Alkaloids such as myrrhizal thiocyanate, tetrahydro-N-methyl thiocyanate and palmitate thiocyanate can promote the spontaneous movement of isolated intestines at low concentrations (0.001-0.002%), while high concentrations (more than 0.01%) can lead to tension increase and movement inhibition. For the isolated frog heart, the drug root was first inhibited and then excited, while the palm leaf fangji was slightly excited. To anesthetized rabbits.

Stable blood pressure: intravenous injection of these alkaloids can cause a temporary or mild decrease in blood pressure. It had no significant effect on the blood vessels of toad's hindlimb. Their antihypertensive effect seems to have nothing to do with the center (no hypotension during vertebral artery injection, no effect on the pressor reflex caused by carotid blood flow occlusion and trachea occlusion), nor affected by atropine, but can inhibit the pressor effect of epinephrine.

4. Anticancer: in the screening test of Ehrlich ascites cancer in vivo, it was found that the ingredient contained in Ehrlich ascites had anticancer effect.

5. Others: it has no effect on sciatic nerve, gastrocnemius muscle, body temperature, blood sugar and so on, and it does not have hemolysis. The top ten meritorious services in South China, including berberine, can be found in Coptis chinensis.
