The planting and sowing management of Scutellaria barbata is very important.

Land selection and preparation: it is better to plough loose and fertile sandy loam or loam. At the same time, 2000 kg of farm manure is applied per mu as base fertilizer.

Propagation method: seed reproduction is the main method, and ramet propagation can also be used. ⑴ seed propagation is mostly direct seeding, from late September to early October, strip sowing or hole sowing. Strip sowing is ditched according to the row spacing of 25-30 cm, and the ditch depth is about 4 cm; the hole seeder opens the hole according to the hole spacing of 27 cm.

When sowing, first sow the seeds in the plant ash mixed with animal dung water, mix them into seed ash, and then evenly scatter the seeds in the ditch or hole, covered with a layer of fine soil or plant ash, the thickness shall not exceed 0.5 cm. After sowing, the soil should be kept moist before emergence, and the seedlings can emerge about 20 days after sowing. Use 1.5-2 kg of seeds per mu. ⑵ ramet propagation was carried out in spring and summer. Dig up the old roots of the plant, select strong, pest-free plants for split, each plant has 3-4 seedlings, according to the hole distance of about 27 cm hole planting, cut and watered.

Field management:

1. When the seedling height is 5-7 cm, the direct seeding of inter-seedling and supplementary seedling should be carried out according to the plant spacing of 4-5 cm, and the seedlings should be transplanted with soil and watered after planting.

2. Weeding and weeding should be carried out in time after each harvest.

3. Topdressing combined with ploughing and weeding, topdressing 2000 kg of human and animal manure water per mu.

Pest control:

In the process of growth, Scutellaria barbata has almost no disease, and aphids and vegetable black insects are easy to occur during flowering. The former can be controlled by dimethoate, and the latter can be sprayed with 50% dichlorvos 1000 times.

Seed retention technique from May to June, when the seeds are gradually mature, the fruit branches are harvested in batches, dried in the sun or shaded, rubbed out the seeds, winnowed the stems and impurities, put them in a cloth bag and stored in a dry place. The continuous cropping field of Scutellaria barbata does not need to leave seeds, and the roots and seedlings can be renewed for 3-4 years.
