Soil ginseng can be cultivated in open field, and it can also be used for annual production in the greenhouse. Its strong growth, less pests and diseases, and suitable cultivation. 1. Sowing Seedlings generally use seeds to reproduce, about 50 grams per mu. When transplanting seedlings, 1 seed is mixed with 10 parts of fine sand or ash, uniformly spread on the seedbed, covered with plastic film, a small arch shed, insulation and moisture. Seedling age 30-40 days, seedlings 3-4 true leaves can be transplanted and colonized. It is also possible to carry out cutting propagation at any time in its growth process, take root after about 10 days of cutting, and it is easy to survive. 2. Soil preparation: Choose fertile, easy-to-irrigation, sandy loam soil, cultivate 2,000 kg per mu, and plow deep into 15 cm, make 1.2-1.5 m wide rice dumplings. , Drilling distance 25 centimeters, open shallow ditch. 25-30 cm line spacing, planting 25 cm planting, planting about 7000 per acre, high temperature areas, cultivation and harvesting time is long, the density of some of the smaller, while the density is higher. After planting drenched root water. 3. After cultivating and weeding, timely weeding and weeding, and then seeing the growth of the field, weeding once every 20 days to keep the field clean. 4. Dwarfing requires dwarfing plants. When the plant height is 10 cm, the growing point can be removed. When the first-stage branches grow to the harvesting length, they are picked and dwarfed. Live fields should be moderately seedlings. 5. Fertilizer management soil ginseng hi moist soil, but not tolerant, generally sunny every 3-5 days, pouring water, the rainy season to rule out the accumulation of water; greenhouse cultivation principle is to see only watering, watering should be sunny morning In order to facilitate humidity, reduce the incidence of disease. After planting the slow-onset seedlings, apply 1 thin decomposing human fecal urine water (such as biogas liquid fertilizer), apply the ratio of manure to water in a ratio of 1:5, or apply the available nitrogen fertilizer, and apply 5 kg of urea per acre. After each harvesting of the stems and leaves, 1,000 kg of thin human and animal manure is applied per acre, or 0.5% urea plus 0.2% potassium dihydrogen phosphate solution is sprayed on the foliage. 6. Disease Prevention and Pest Control Soil pests and ginseng rarely cause pests and diseases, and pesticides and chemical fertilizers may not be used. When aphids occur, they can be sprayed with a solution of 800-1000 times 0.5% veratrine solution. 7. The harvested and stored edible parts are their tender shoots, young leaves, tender shoots, and their main roots. From spring to autumn, tender shoots, young shoots, and young leaves can be harvested. 1 harvest small plants. Live seedlings can be harvested in small batches after 5 cm in height. 2 Harvest stems and leaves. When transplanted seedlings are about 20 cm tall, leave 6-8 leaves to pick the main stem tip, 8-10 cm long. After the top two pairs of leafhoppers pull out new shoot tips, they grow to about 10 cm long, leaving the most basic one. On leaves, picked on leafy sections. In the summer and early autumn, it is easy to pump spikes when planting, and it should be picked in time when the flower spikes are drawn out. New shoots will continue to be extracted, and 1-2 pairs of bases will remain in the base at the time of picking, which can be harvested and harvested continuously. If picking is not timely, Spike flowering inhibits the development of lateral shoots, which reduces yield. 3 Harvested fleshy roots. In the fall, excavation of fleshy roots can be carried out. After the roots are dug out, they can be washed to remove sediment. Then the skin can be scraped off and steamed and dried. Generally, 50-75 kilograms of dry product can be produced per mu, which can be used as medicine for 2-3 years. Excavation results in high yield, strong drug taste and good quality. But after rooting, it is impossible to harvest the stems and leaves. Shandong YingLang Chemical Co.,Ltd , https://www.sdylhgtrade.com
