Planting techniques of Prunella vulgaris

Prunella vulgaris is a genus of Prunella vulgaris in the Labiatae family, which is a perennial herb, also known as Prunella vulgaris, Prunella vulgaris, Prunella vulgaris and so on. It is a common Chinese herbal medicine with the effect of clearing the liver and eyesight, dispersing knots and detoxification. The main treatment of eye deviation, pulmonary tuberculosis, breast cancer and other diseases, planting Prunella vulgaris is a good way for farmers to get rich, let's take a look at Prunella vulgaris planting technology!

Growth habits of Prunella vulgaris

Prunella vulgaris is mainly distributed in Shaanxi, Gansu, *, Henan, Hubei, Hunan, Jiangxi, Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Guizhou, Sichuan and Yunnan provinces and regions. Prunella vulgaris prefers warm and humid environment, cold tolerance and strong adaptability. however, it is better to use sandy loam with sufficient sunshine and good drainage, and can also be planted on dry slopes, hillsides, forest grasslands, roadsides and fields, but low-dust and waterlogged lands are not suitable for cultivation.

Propagation techniques of Prunella vulgaris

1. Ramet propagation: Prunella vulgaris ramet propagation usually dug out the old root at the end of spring and dug holes according to the row spacing of 25 × 10 cm. Two plants were planted in each hole. After planting, the soil was compacted and watered to keep the soil moist, and seedlings emerged in 7 days.

2. Seed propagation: when the flower ear of Prunella vulgaris turns yellowish brown, pick the ear to dry, shake off the seed, remove its impurities and store it. Northern spring sowing in late March to mid-April, autumn sowing in late August, multi-use strip sowing, ditching on the border according to the row spacing of 20-25 cm, with a depth of 0.5-1 cm. The seeds were evenly sowed into the ditch to cover fine soil, slightly suppressed and watered, and the soil was often kept moist. Seedlings emerged in about 15 days, and the amount of seed used per mu was 0.51kg.

Planting techniques of Prunella vulgaris

1. Land selection: Prunella vulgaris should be planted in Hatton sandy soil fields or plots with sufficient sunshine and good drainage, and deep ploughing and fine raking should be made before sowing, so that the soil is flat. 2000 kg of mature pile barnyard manure or 48% imported compound fertilizer is applied per mu, and then the soil and fertilizer are mixed well, and the three ditches are opened for sowing (or raising seedlings) at the same time.

2. Seedling sowing: it is usually the best time to sow and raise seedlings from mid-late August to the end of September, sowing or sowing when the soil moisture is good. When sowing, the seeds can be mixed with fine sand or fine soil to sow evenly, while controlling the sowing rate, sowing 1.0-1.5 kg per mu. On-demand sowing can be directly sowed with seeds, sowing 8-10 seeds per hole, 17000 holes per mu, 0.5-1.0 kg per mu, and cover the soil lightly after sowing. In case of drought after sowing, water should be replenished or horse running water should be irrigated in time. Seedlings will emerge after 15-20 days, and weeding will be carried out manually for 1-2 times at seedling stage.

3. Weeding seedlings: when Prunella vulgaris seedlings are about 4 leaves, Prunella vulgaris leaves large seedlings, weak seedlings remain strong seedlings, seedlings are fixed at about 10 leaves (beginning of tillering), and the basic seedlings are determined according to the row spacing of 5 to 6 inches, basically ensuring 2 to 3 strong seedlings per plant.

4. Reasonable topdressing: Prunella vulgaris topdressing is generally carried out twice, the first time is sprinkled with urea 5kg / mu at the tillering stage around the middle of March and 10kg / mu with imported compound fertilizer 10kg / mu at the end of flowering stage around the middle of May. Topdressing should be carried out when the soil moisture is good or before rain, so that the fertilizer can be better absorbed by crops.

5. Harvest and processing: Prunella vulgaris is sown in spring and harvested in autumn in the second year, and harvested by stages because of the maturity of Prunella vulgaris. The general length is more than 8 cm (ball interlayer is more than 13 layers) can be exported and can be packed by grade. When most of the balls are yellowish brown, the clubs and balls can be cut, dried and stored together, and the clubs will be graded and packed for sale when they are idle. The old mackerel can be retained after harvest and can continue to grow.
