Seed price and planting method of Clematis roxburghii

Clematis is a plant of the genus Cymbidium of Orchidaceae, with very high medicinal value, and the whole grass can be used as medicine. It has the effects of clearing heat and dispelling wind, promoting dampness and detoxification, relieving pain and relieving cough, and so on. In the folk, there are golden thread, golden earrings, bird ginseng and other laudatory names. Wild resources are very scarce, so it has a very high cultivation value. Let's take a look at the seed price and planting method of Clematis.

How much is the seed of Clematis roxburghii?

The price of Anoectochilus roxburghii seedlings is about 0.3-0.5 yuan per plant. Anoectochilus roxburghii seeds germinated naturally before no cell tissue culture, but the seeds were very fine, there was only one immature embryo in the seeds, the germination power was very low, and the seed coat was not easy to absorb water, so it could not germinate by conventional methods. Therefore, it is necessary to use blue bacteria or artificial culture medium to provide nutrients to germinate, and it takes half a year to one year from sowing to transplanting. Therefore, the production of Anoectochilus roxburghii is often propagated by cell tissue culture.

Growth environment of Anoectochilus roxburghii

Anoectochilus roxburghii is distributed in Fujian, Taiwan, Guangdong, Guangxi, Hainan, Sichuan, Guizhou, Yunnan, Hubei and other subtropics and tropics. It is cool and humid, especially in the ditch edge, stone wall and loose soil of evergreen broad-leaved trees. It requires a temperature of 20: 32 ℃, light 3000~5000LUX, too strong light can easily lead to plant stem creeping, too weak light can easily lead to plant stem slender. But different varieties of Anoectochilus roxburghii have different light requirements.

Planting conditions of Clematis roxburghii

1. Site selection and construction shed: Anoectochilus roxburghii planting chooses areas with open terrain, north facing south, tall broad-leaved forest around, away from pollution sources, to build a greenhouse with strong wind resistance, the roof and its surroundings are first covered with film and then covered with a sunshade net to control the temperature, light and humidity in the shed.

2. Installation of iron frame: the planting iron frame is usually used to put the planting tray in the production of Anoectochilus roxburghii, and the cultivation substrate is placed in the tray. The iron frame is 1 meter wide and 1.5 meters high, and the length is determined according to the greenhouse. It is divided into three layers, the distance between layers is 45 cm, and the distance between the two rows of iron frames is 60 cm to 80 cm.

3. Stubble arrangement: Anoectochilus roxburghii is usually planted in two seasons a year, transplanting in early March in the first season, harvesting in late June, transplanting in early September and harvesting in late December in the second season to ensure that the plant grows in the soil for more than 4 months. to improve the yield and the medicinal composition of the product.

4. Substrate selection: Anoectochilus roxburghii cultivation is usually arranged according to peat soil: husk: fine sand = 10:1:1. After sun disinfection, 5kg 7.5kg cooked lime or an appropriate amount of carbendazim wettable powder is added to the cultivation substrate.

Planting method of Clematis roxburghii

1. Variety selection: at present, Fujian varieties and Taiwan varieties are widely cultivated, both of which have good adaptability and are liked by consumers, especially Liangyeshan and Guanlushan wild Clematis are very popular after artificial cultivation. Taiwan varieties are sensitive to low temperature.

2. Seedling raising method: tissue culture seedlings should be adopted in large-scale cultivation of Clematis roxburghii. Tissue culture seedlings can keep the excellent characters of mother plants and the plants are neat. It is required to select seedlings in greenhouse for more than 15 days, seedling height more than 6 cm, and tissue culture seedlings with 2 leaves for transplanting.

3. Reasonable close planting: Clematis is planted according to the row spacing of 2 × 5 cm, 150 plants are transplanted on each tray, the seedlings are washed with clean water, the depth of planting is about 1 cm, and deep planting is avoided. After planting, spray with 45% carbendazim wettable powder 800 × 1000 times.

4. Post-planting management: Anoectochilus roxburghii was sprayed with 10% amino acid 500x solution every 7 days after transplanting for a week, and covered with film within 15 days after transplanting. The temperature in the greenhouse was controlled between 20: 27 ℃, the air relative humidity was 70: 80%, and the substrate humidity was 70: 75.

5. Pest control: the pest control net is set around the planting greenhouse, and the small tigers are killed by sugar and vinegar, or biological pesticides such as bacteria, fungi, viruses, plant extracts, antibiotics and other biological pesticides are used to kill diseases and insect pests. Chemical control needs to choose high-efficiency, low-grade, low-residue pesticides.

6. Harvesting and processing: Anoectochilus roxburghii is more than 10 cm high, has 5 cm 6 leaves, 2 cm wide, 2.5 cm wide, 3 cm long, 3 cm long, purplish red on the back of the leaf, obvious golden vein net on the leaf surface, and green stem can be harvested. When harvested, the soil is shaken, washed, dried or dried.
