Salvia miltiorrhiza, also known as red root, is a perennial herb with a plant height of about 60 cm and a root of 30 cm in length. Under general cultivation conditions, 1/15 hectares (1 mu) of dry medicine yields 500 kilograms and the economic benefits are relatively high. However, due to the "root" planting of Salvia miltiorrhiza, it will take 25-30 days before emergence. The emergence rate in the field is only about 60%. Especially in the case of poor soil moisture, the emergence rate is even lower, and it is very easy to cause seedling emergence. Broken ridges, thus affecting the increase in production and economic efficiency. In order to solve this problem, after several years of trials, we adopted and mastered the seedling raising technology of Salvia miltiorrhiza. The following are briefly introduced as follows: Before and after the construction of the convulsions, select the leeward sunny place. The seedbed is dug to a depth of 30 cm and a width of 130 cm. The number of roots is determined by the use of adobe, brickwork or earthen walls with wooden plywood. The northern wall is 50 centimeters high, the south wall is 20 centimeters high, and the east and west walls are beveled. A layer of horse manure or wheat straw with a thickness of about 7 cm is laid on the bottom of the bed as a heating material, and then a layer of “breeding soil†mixed with fine sand, dung, and fine soil is used. Dung and fine soil should be sieved to a thickness of 15 cm. Go to bed and plant the roots of Salvia miltiorrhiza vertically on a nursery bed with a 10 cm spacing and a 5 cm spacing. After cutting, cover 1 cm thick fine soil, and then gently pat the flat, spray the bed with warm water of 30-40 °C, once irrigated with water, after the water infiltration, cover with plastic film and plastic film. The perimeter of the management film should be tightly covered with mud pressure. The top of the film should be covered with grass blankets. The sun should be opened on a sunny day and covered at night. It is advisable to keep the temperature in the bed at 20-25°C. When the temperature in the bed reaches 30°C or more, peel the plastic film on both ends of the bed to a small part in time to cool the ventilation and keep the seedbed moist. The seedlings began to germinate in 20 days, and the new leaves began to expand in 30 days. When the seedlings height was 2-3 cm, they were selected to uncover the thin-film solar seedlings at noon and they were still covered with a film at night, and they needed to be seedlings for 10 to 15 days. When the seedlings are transplanted to a height of about 7 cm, they can be transplanted into the field. Before transplanting, pour enough water into the hotbed and dig the seedlings with a spade. Do not pull it out by hand. Field planting should be ridged, ridge height 20 cm, row spacing 40 cm, plant spacing 24 cm, 50% carbendazim or 50% fungal excision 1.5 kg per 1/15 ha after ditching Disinfect the soil, then plant the seedlings, water the soil, and then cover the soil after the water has penetrated.
