How to accelerate the germination of ginseng seeds?

How to accelerate the germination of ginseng seeds? What should I pay attention to? I also hope that experienced netizens can help introduce that ginseng seeds need to be germinated before sowing. The planting network has sorted out the methods of accelerating germination of ginseng seeds in the same year and the next year, which are listed below for netizens' reference. The method of accelerating germination of ginseng seeds in that year: the seeds harvested in that year can be treated by accelerating germination after drying the epidermis, in the early stage, in the outdoor seed germination shed, and in the later stage, in a wooden box. When the seed crack reaches more than 90%, 90% of the ginseng seeds have an embryo rate of more than 80%. It is necessary to carry out physiological post-ripening, freeze storage in time after physiological post-ripening, and take out sowing in spring sowing. Preparation of sprouting boxes and stores: frames made of 2-3 "plank, 40" high and 100 "wide, depending on the number of seeds and the site. The outer frame is made of wood of the same thickness, 15 inches away from the inner frame, and the soil can be filled in the middle without the outer frame. The soil can be cultivated firmly at the outer edge of the inner frame, and the same box slot can be built with bricks, and a small number of seeds can be germinated in wooden boxes. Select the site with high dry terrain, good drainage and leeward to the sun, the loose ground is smooth and steady; according to the specifications of the box slot, set up the sprouting box slot on the flat ground. Treatment and sprouting of ginseng seeds: before packing, the dry seeds were soaked in cold water for 24 hours, and the water seeds were soaked in gibberellin 100 mol / L water for 20 hours. they were removed and dried to the surface and sterilized with fungicides (low toxic pesticides). Sprouting substrate, can be used humus soil and river sand (must be sifted) mixture, humus: River sand = 2:1. Spread 5 grams of substrate at the bottom of the box, then fill it with a mixture of matrix and seeds (3:1), then cover the upper layer with 10 grams of substrate, and adjust the temperature. Management of ginseng budding period: set up a transparent and impervious shed, the sun mouth to the north, dig a good drainage ditch around the site to prevent Rain Water from soaking into the budding trough. The seeds were replanted every 10-15 days in the early stage of germination and every 7 days in the later stage, and the moldy seeds were picked out. The method of inverting seed: take out the seeds mixed with the substrate from the box trough, put them on the flat ground and fully turn over and pick out the moldy seeds, and adjust the water content of the substrate when pouring the seeds. When sprouting with pure sand, the substrate degree should be adjusted between two times to prevent the phenomenon of over-wet and over-dryness. the humidity of mixed soil and pure humus should be 20%, 30% and 40%, respectively. the humidity of crack matrix should be kept at a low level. The substrate temperature in the early stage of germination should be 18-20 ℃, and the temperature should not exceed 25 ℃. The seeds with more than 25 ℃ are prone to mildew and rot. In the later stage of germination, the substrate temperature should be kept at 13-15 ℃. Ginseng seed storage standards and storage methods the seed crack rate is more than 90%, and 90% of the seed embryo length is more than 80% of the endosperm length. The seeds that reach the germination target can not be sowed in autumn in the same year, and should be stored well over the winter. During storage, the seeds should be physiologically ripened (the temperature is 0-5 ℃), then frozen, and can not be thawed before sowing. The method of accelerating germination of ginseng seeds every other year: normal treatment time: germination was usually carried out before the end of June, mostly outdoors, cracks in ginseng seeds in late August, and morphological development of seed embryos at the end of September. The seeds can be sown in the autumn of that year. Ginseng seed germination box and site preparation: use 2 "3" thick plate frame, frame height 40 ", width 90" 100 ", length according to the number of seeds and site. The outer frame is made of wood of the same thickness, which is 15 inches away from the inner frame and filled in the middle. Can also not use the outer frame, in the outer edge of the inner frame to cultivate solid soil, brick into the same box groove can also be, a small number of seeds can be used to sprout in wooden cases. Select the site with high dry terrain, good drainage and leeward to the sun, and the loose ground is smooth and stable; according to the specifications of the box slot, set up the sprouting box slot on the flat ground. Treatment and germination of ginseng seeds every other year: before packing, the dry seeds were soaked in cold water for 24 hours, and the water seeds were soaked in gibberellin 100 mol / L aqueous solution for 20 hours, then dried to the surface and sterilized with fungicides (low toxic pesticides). Germination substrate, you can use humus, river sand (must be sifted) or humus: 2:1 mixed soil of river sand. Spread 5 grams of substrate at the bottom of the box, then fill it with a mixture of matrix and seeds (3:1), then cover the upper layer with 10 grams of substrate, and adjust the temperature. The next year ginseng seed budding period management: set up a light-impervious shed, the sun mouth to the north, dig a good drainage ditch around the site to prevent Rain Water from soaking into the budding trough. The seeds were planted every 10 to 15 days in the early stage of the crack and every 7 days in the later stage of the crack, and the moldy seeds were picked out during the fall. When sprouting with pure sand, we should pay attention to adjust the substrate degree between the two toppings to prevent the phenomenon of over-wet and over-dryness, using mixed soil to promote germination, the substrate temperature is 20%-30%, and the substrate temperature of pure humus soil is 30%-40%. The temperature of the crack matrix should be kept at a low level. The matrix temperature was kept at 15: 20 ℃ in the early stage and 13: 15 ℃ in the later stage. Storage standard and storage method: the seed cleavage rate is more than 90%, and 90% of the seed embryo length is more than 80% of the endosperm length. The seeds that reach the germination target can not be sowed in autumn in the same year, and should be stored well over the winter. During storage, the seeds should be physiologically ripened (the temperature is 0: 5 ℃), then frozen, and can not be thawed before sowing.
