First, characteristics
Plant height 10-30 cm, the whole plant was gray-brown hair. The main root is slender, 30-40 cm, dense and succulent, with yellowish-white skin, 0.5-1.5 cm in diameter, and less branched. Stems erect, unbranched, mostly buried in sandy soil. Basal leaves, leafy ovate or triangular-ovate, umbellate terminal, flowers small, white. Double-suspended fruit, spherical or elliptic, with corky fins, brownish hairs, yellow-brown when ripe. Flowering from May to July, fruiting from June to August. The northern sea ginseng has strong adaptability, prefers warm and humid climate, drought and cold resistance, and hi sandy soil. Avoid flooding, avoid continuous cropping, avoid strong sunlight. Except for the seedling period and the need for sufficient water for seeding in reserved fields, it is not easy to water more in the later growth period. Former crops are best served with potatoes. Avoid soybean, peanut crops, the germination rate of the seeds decreased significantly in the next year, lost the ability to germinate in the third year. The seed germination rate is high in winter and seedlings are homogeneous. The seedlings emerged before and after the second rainy season in winter sowing, but generally they did not bloom and the results were only bloomed in the third year. The germination rate in the spring sown in the following year was significantly reduced, and the fruit was only bloomed in the second year. After small hours, it was convulsed, and flowered one week later. The flowering period was two weeks. The seed before and after the head was matured.
Second, cultivation technology
1. Soil preparation and fertilization. Artificially cultivated northern sea ginseng should be selected as a bed with deep soil, good drainage, loose and fertile, sunny loam, sandy loam soil or humus loam soil. Mushi Fertilizer 2000 kg. The use of large ridge bed technology, bed width 130-140 cm, length as required, bed height 10-12 cm, bed spacing 30 cm.
2. Breeding technology. (1) Seed cultivation. After harvesting in the autumn, select good plants with strong plants, no pests and diseases, uniform plant type, and no flowering in that year as the mother plant, plant in the reserved land, each row spacing 25 centimeters apart, and press the “product†shape to dig a hole, each hole One planted and carefully cultivated after planting. When the fruit turns yellow in the following summer, the fruit sequence is cut and placed in a ventilated and dry place to dry and thresh, and the seeds are collected and stored for broadcast. Fields can be harvested continuously for several years, but they must be carefully managed. (2) Seed treatment. The new seeds were mixed by seed and clean Xihe sand at the ratio of 1:3 before entering the winter, and were placed in a wooden box and buried in the ground for 15-30 centimeters over the winter to allow them to undergo a low temperature stage for germination. Keep it moist during the spring and take it out after thawing in late spring. (3) sowing. Autumn sowing is carried out before freezing in the autumn and spring sowing in the middle or late May. It is advisable to use 5 cm below the ground when the temperature is stable above 15°C. When sowing, in the well-made bed, according to the spacing of 20 cm, shallow 3-5 cm deep ditch, cover soil 2-3 cm, a little repression. The sowing rate per acre is 7-8 kg.
3. Field management. (1) Weeding and weeding. After the emergence of timely cultivator weeding protection, in order to facilitate seedlings. Because the northern sea cucumber is a dense planting crop, it is not suitable to use hoe cultivator, and you can use shovels to loosen soil or weed it. (2) Miao, Dingmiao and Miao Miao. Seedling height 5 cm seedlings, spacing 3-5 cm. (3) Dressing. Fertilizers were grown 3 times during the growing season. For the first time after the seedlings were flushed, 1,500 kilograms of light manure water was used for the first time; after the second time, the second half of the seedlings were decomposed with 2,500 kilograms of manure, livestock and manure water. The third time after the roots expanded in July, the growth period of the bark was increased. Manure 2000 kg superphosphate 20 kg, 30 kg cake, root growth. (4) Irrigation and drainage. Seedlings after sowing, keeping the soil moist. During the rainy season, pay attention to timely drainage and flood prevention. (5) Lei. Buds are cut off immediately after emergence to prevent nutrient consumption.
Third, harvest processing
The planting cycle can be divided into 1 year, 2 years and 3 years. Harvest time is very important to ensure the quality of medicinal materials. The best harvest time for one year is appropriate from mid-September to mid-October. The two-year or three-year harvester should be suitable within five days of the summer solstice. The medicines collected at this time are solid, powdery, good quality, and high in yield. 350-450 kilograms of dried medicinal herbs per mu.
