It is harvested when the ear is brownish red in summer. the medicine has the effect of clear fire and clear vision, loose knot and detumescence. Let's take a look at the seed price and planting method of Prunella vulgaris.

How much is the seed of Prunella vulgaris per jin?

The price of Prunella vulgaris seeds is about 4050 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of the seeds. Prunella vulgaris grows in gully wetlands or wet grass on both sides of the river bank, wasteland, roadside, and can be planted on dry slopes, foothills, forest grasslands, roadsides and fields. when the flowers turn yellowish brown, pick the fruit to dry, shake off the seeds, remove their impurities and store them.

Sowing method of Prunella vulgaris

Prunella vulgaris can be sowed in spring or autumn, spring sowing in late March to mid-April, autumn sowing in late August. During strip sowing, ditches were opened on the border according to the row spacing of 20 cm to 25 cm, and the ditch depth was 0.5 cm. Then the seeds were evenly sown in the ditch to cover fine soil, slightly suppressed, watered, and often kept moist. Seedlings emerged in about 15 days, and the amount of seeds used per mu was about 0.5 kg. On-demand sowing can be directly sowed with seeds, sowing 8-10 seeds per hole and 17000 holes per mu.

Planting methods of Prunella vulgaris

1. Land selection and land preparation: Prunella vulgaris prefers warm and humid environment, cold tolerance and strong adaptability, but sandy loam with sufficient sunshine and good drainage is better, and it can also be planted on dry slopes, hillsides, forest grasslands, roadsides and fields. but low dust and waterlogging land is not suitable for cultivation.

2. weeding seedlings: when Prunella vulgaris seedlings are about 4 leaves, Prunella vulgaris is combined with weeding to remove small seedlings to keep large seedlings, weak seedlings to keep strong seedlings, to set seedlings at about 10 leaves (beginning to tiller), and to set basic seedlings according to 5-6 inch row spacing, basically ensuring 2-3 strong seedlings per plant.

3. Reasonable topdressing: Prunella vulgaris topdressing was generally carried out twice, the first time was sprinkled with urea 5kg / mu at the tillering stage around the middle of March, and the second with 10kg / mu of imported compound fertilizer at the end of flowering stage around the middle of May.

4. Harvest and processing: Prunella vulgaris is sown in spring in the same year and sown in autumn in the following year. When 80% of the ears of the plant are yellow and gradually brown in June, they can be cut off on a sunny day or cut back to dry the seeds, and the hay and dried ears are stored separately and sold at a price.

Pest control of Prunella vulgaris

1. Mosaic virus disease

[symptoms] mosaic, leaf deformity and plant dwarfism, uneven thickness of diseased leaves, uneven leaf color, abnormal wrinkle.

[prevention and treatment] at the initial stage of the disease, spray with 500 times of 20% Shiduqing wettable powder, 1.5% Zhishanling emulsion, 20% morpholine guanidine hydrochloride wettable powder 400 times, once every 10 days, 2 ~ 3 times.

2. Scorch leaf disease

[symptoms] at the initial stage, red disease spots appeared in the leaves, and gradually expanded, resulting in the scorching and shedding of all the leaves.

[prevention and treatment] at the beginning of April, 70% methyl thiophanate wettable powder 800 times liquid, 75% chlorothalonil wettable powder 600 times liquid spray control, pay attention to alternate use of drugs.

3. Big gray weevil

[harmful] the larvae and adults feed on the tender tips and leaves of Prunella vulgaris, the light ones eat the leaves into notches or holes, and the serious ones eat the Prunella vulgaris into smooth rods, resulting in lack of seedlings and broken ridges.

[control] 1.8% avermectin EC 2000 times, 20% chlorophenol benzamide gel suspension 3000 times.
