How to plant Prunella vulgaris

1. Seed propagation: it can be sown in both spring and autumn. Spring is in the early and middle of March: autumn sowing is suitable in early September. Direct seeding is often used, the seeds are mixed with some fine sand, and they are evenly sprinkled on the border that passes through the land preparation or in a shallow ditch with a row spacing of 33 centimeters. About 10 Murray seedlings emerged in 15 days. 2. Ramet propagation: generally, after the old roots sprout in spring, the roots are dug up and separated. Each root needs to be planted with 2 buds, which are planted as soon as they are dug. According to the row spacing of 27muri 33cm, the hole spacing of 16mur20cm, planting 1 plant in each hole, compacting after planting, watering to fix the root. Prunella vulgaris sowing is generally divided into two kinds: strip sowing and sowing. Strip sowing should be ditched with a hoe according to the row spacing of 5mur7 inches, and the seeds can be evenly scattered in the ditch. Sowing can spread the seeds evenly on the border surface, sweep gently with a broom after planting, and cover the seeds. If the soil moisture is poor, it should be covered with straw to moisturize, sprinkle water after cover, keep the border surface moist, and remove the cover straw in time after emergence. The amount of seed used per mu is about 1.5 kg. Because the land utilization rate of intercropping is low, the amount of seed used is generally 0.5 tons / mu.
