How do you raise Salvia miltiorrhiza seedlings? What method is best for raising Salvia miltiorrhiza seedlings? Please describe the methodAfter the "seed roots" of Salvia miltiorrhiza are planted, it takes 25-30 days for seedlings to emerge, and the field emergence rate is only about 60%. Especially when soil moisture is poor, the emergence rate is even lower, which easily causes missing plants and broken rows, thereby affecting the increase in yield and the improvement of economic benefits. To raise Salvia miltiorrhiza seedlings well, you can refer to the following method:
Building the bed for Salvia miltiorrhiza seedlings:Around Awakening of Insects, choose a sheltered, sunny spot. Dig the seedbed 30 cm deep and 130 cm wide, with the length depending on how many "seed roots" there are. Build the surrounding walls with adobe, brick, or earthen walls made with wooden clamp boards. The north wall is 50 cm high, the south wall is 20 cm high, and the east and west walls are sloped. Spread a layer of donkey or horse manure or wheat straw about 7 cm thick on the bottom of the bed as fermenting material, then spread a layer of "seedling-raising soil" mixed from fine sand, barnyard manure, and fine soil, with each accounting for 1/3. The barnyard manure and fine soil should be sieved, and the thickness is 15 cm.
Putting Salvia miltiorrhiza seedlings onto the seedbed:Insert the "seed roots" of Salvia miltiorrhiza vertically into the seedling bed, with a row spacing of 10 cm and a plant spacing of 5 cm, with the thick end facing up and not upside down. After inserting, cover with 1 cm of fine soil, then gently pat level, spray the bed surface with warm water at 30-40°C, watering thoroughly in one go, and after the water seeps down, cover with plastic mulch and plastic film.
Management of Salvia miltiorrhiza seedlings: The film must be covered tightly all around and pressed down with mud. Cover the film with straw mats on top. On sunny days, uncover it to sun the bed, and at night cover it well to keep warm. The temperature inside the bed should be kept at 20-25°C. When the temperature inside the bed reaches above 30°C, promptly uncover a small part of the plastic film at both ends of the bed for ventilation and cooling. The seedling bed should be kept moist. After 20 days, the young seedlings begin to sprout; after 30 days, new leaves begin to unfold. When the seedlings are 2-3 cm tall, choose warm midday to uncover the film to sun the seedlings, and still cover with the film at night. Sunning the seedlings needs 10-15 days.
Transplanting Salvia miltiorrhiza seedlings:When the seedlings are about 7 cm tall, they can be transplanted to the field. Before transplanting, water the hotbed thoroughly, and dig up the seedlings with a small shovel; never pull them out by hand. Field planting should use ridging, with a ridge height of 20 cm, row spacing of 40 cm, and plant spacing of 24 cm. After opening the furrow, apply 1.5 kg of 50% carbendazim or 50% tuijunte per 1/15 hectare along the furrow for soil disinfection, then plant the seedlings, water, and cover with soil after the water seeps down.
