I like cold and humid climate, and I have strong cold resistance in direct sunlight. Seeds can be stored in the shade, and embryos have morphological and physiological characteristics. The former requires a temperature change of 20- 10℃, and the latter requires a low temperature of 2-4℃, each of which takes 3-4 months, and the seeds that are not ripened cannot germinate. Strict requirements for soil, suitable for planting in sandy loam and humus loam with rich organic matter and good permeability, to avoid continuous cropping.

Step 2 sow seeds

Before sowing, the ridge should be well prepared, with the ridge height of 23-33 meters, width of 126- 133 cm, and the ridge working path of 2-2.66 cm. Sowing, 0.5g per square centimeter. After sowing, cover the soil for 3-4cm, and keep the soil moist frequently until the seedlings emerge in early May. Spring sowing is in early and middle April. Sow in summer in July and August, pick the fruits when they are ripe, and sow them immediately. Autumn sowing is in June165438+1October.

Step 3 accelerate germination

1 seeds are mixed with 3 river sands, and the soil surface is sprayed with a new high-fat film 600-800 times to improve the emergence rate. Immediately put it into the germination box and put it in a suitable place indoors or outdoors for germination. Pay attention to frequent inspection, frequent digging, and control the sowing temperature and temperature. Fusong, Jilin often sows dry seeds (dry seeds harvested last year) in late June.

Step 4 transplant

Spring sowing should end in the middle and late April, which is suitable for the germination of overwintering buds. /kloc-65438+ planted in autumn in the middle and late October is suitable for planting before soil freezing.

5, climate spacing

Before emergence, a shed with a front eaves height of 100- 133 cm and a rear eaves height of 66- 100 cm should be set up for shading. With planting, the spacing between rows is (15-30)×(6- 12) cm, planting horizontally or obliquely, and covering with soil for 5-9 cm. The shed is divided into full shade shed, transparent shed, single transparent shed or double transparent shed, which can be selected according to climate, soil quality and terrain conditions.

6. Tian Tuan management

Cover the edge, after emergence, cover with broken straw or semi-rotten leaves. Loosening and weeding are generally carried out 3-5 times a year to prevent soil hardening, eliminate weeds and cultivate soil and raise seedlings. When topdressing, organic fertilizer should be applied to the side of ditch root. Thinning flowers and picking buds, leaving Taneda, thinning the middle flower buds of inflorescence 1/3- 1/2 at the initial flowering stage; In the production field, all flower buds are picked before flowering.

Winter protection, before freezing, the boundary is covered with soil or fallen leaves, with a thickness of 5- 15 cm. Set up a wind barrier at the entrance of Shenqi fortress or tuyere to prevent frostbite. ?

Extended data

The main effective chemical components in ginseng, panax notoginseng and panax quinquefolium are dammarane tetracyclic triterpenoid saponins, while other types such as panax notoginseng, panax japonicus and its varieties, panax notoginseng and panax notoginseng mainly contain oleanane pentacyclic triterpenoid saponins, which are similar to those in dozens of families such as cucurbitaceae, labiatae and Oleaceae.

Ginseng grows in coniferous forests and broad-leaved forests. It likes hillsides, is moisture-resistant, and is rich in soft organic matter and fertile soil with good drainage. It grows particularly well in oblique light, but poorly in too dark or strong light. The soil is slightly acidic to neutral (pH4.95~5.95), and ginseng is cultivated in China, Korea and the Far East of the Soviet Union. Panax notoginseng is widely planted in China, Yunnan and Guangxi.

Ginseng is an integral part of "East Asia-North America" flora, which originated in the Paleotropical mountainous area of Tertiary. The modern distribution center of Ginseng is in southwest China, with 5 species, while the famous Chinese medicine Ginseng is distributed in northeast China, northern Korea and eastern Siberia of the Soviet Union.

Ginseng plants in North America are all covered by Quaternary glaciers, but only Panax quinquefolium and Panax trifoliata are preserved in the mountains along the east coast of North America. Like ginseng, it has become an ancient residual plant with intermittent intercontinental distribution.
