Seedling raising and transplanting of Angelica sinensis

Seeds and seedlings are generally sown with picking and sowing around the beginning of autumn, and it is suitable to sow seeds from mid-August to early September in low-altitude areas with slightly higher temperatures. Timely sowing can avoid early bolting of Angelica sinensis. Early, the seedling growth period is long, the seedling is easy to bolt in advance; too late, the growth period is short, the temperature has dropped, and the seedling growth is poor. Using strip sowing, the horizontal trench was opened according to the row spacing of 25 cm on the finished border surface, the depth of the ditch was 3-5 cm, and the bottom of the ditch was leveled. Before sowing, soak the seeds in 25: 30 ℃ warm water for 24 hours, take out and dry, sow evenly in the ditch, cover the fine soil, so that the seeds are not seen. Finally, cover the border with grass about 3 cm thick. The seed consumption is 60-75 kg per hectare. The seedlings emerged about 15 days after sowing. One month later, when the seedlings are 1cm or 2cm high, gently shake the cover grass on a cloudy day, and then take it off carefully to prevent the seedlings from drilling into the cracks in the grass, causing damage to the seedlings. After uncovering the grass, weeds should be removed when you see them, and there should be no weeds in the field, and the seedlings should be removed, weak and strong, and the distance between plants should be kept about 1 cm apart. In mid or late October, when the leaves of the seedlings are yellow and withered, dig up the seedlings, bundle them into small bundles 5 to 6 centimeters thick, cut off the upper stems and leaves, carry out some soil on the roots, dry the water vapor and store them in cellar. Can also be in the indoor dry to the sun, dig a moderate size of the pit, about 60 cm deep, the bottom of the pit first covered with a layer of 5 cm 7 cm of fine sand, its upper layer of seedlings, and then covered with a layer of fine sand, so alternately laid to 15 cm from the top of the pit, sealed with dry soil, about 30 cm thick, the top of the pit made of tortoise back shape. The seedlings can also be stored in a special square bamboo basket with fine sand and stored in a cool and dry place indoors. This method is simple and easy to manage.
