Baikal skullcap root, folk called camellia root, earth gold tea root. Root can be used as medicine, cultivation value is high, with clearing away heat and detoxification, hemostasis function. Do you know how to grow this herb scutellaria baicalensis? The best way to see it all is here!

1. Sowing method of scutellaria baicalensis

1. direct seeding

Direct seeding is the best way to obtain high yield and high quality. Both spring and autumn can be sown. Spring sowing is carried out before and after Qingming, generally when the ground temperature reaches 5℃~8℃, sowing can be carried out; autumn sowing is generally carried out before and after white dew, and the ground temperature is stable at 0℃~5℃.

2. seedling transplanting method

The sowing time of scutellaria baicalensis seedlings is the same as that of direct seeding, and fertile soil, convenient irrigation and drainage, loose sandy loam soil are selected. The soil layer depth is required to be more than 40 cm, and the row spacing is 20~25 cm when sowing. The ditch is 3 cm deep and the sowing width is 10 cm. Mix the seeds with turf ash and sow them evenly into the ditch. The soil thickness is 2 cm. Press it slightly, irrigate it thoroughly, and cover the grass on the ridge to keep warm and moist. When the temperature is 14~15℃, the humidity is appropriate, and the seedlings can emerge in about 10 days. Later strengthen management, when the seedlings grow to 13~15 cm, root length of 15 cm can be transplanted. Transplanting is carried out in spring, holes are opened on the well planted bed surface according to the row spacing of 20~24 cm and the plant spacing of 1 ~ 2 cm, and 1~2 seedlings are planted in each hole. When planting, the roots should be naturally extended, not bent, compacted, and should be carried out in rainy days. Sowing to the emergence period to keep the ground wet or add mulch to promote emergence.

II. Fertilization and Disease Control of Radix scutellariae

1. Fertilization

Fertilization: When the height of scutellaria baicalensis seedlings is 10~15 cm, topdressing is applied once, and the application amount is 1500~2000 kg of human and animal manure water per mu. From the end of June to the beginning of July, 20kg of calcium superphosphate and 5kg of urea were applied per mu, furrowing between rows, watering after covering soil.

Topdressing: after the plants harvested in the next year are withered, furrows are opened and topdressed with decomposed manure 2000kg, calcium superphosphate 20kg, urea 5kg and plant ash 150kg per mu, and then covered with soil.

2. Disease and pest control

Leaf blight: clean the countryside, spray Bordeaux mixture in the ratio of 1:1:200 in the early stage, or use 50% carbendazim 1000 times solution to control it.

Root rot: pay attention to drainage, implement rotation, early allocation of diseased plants burned, diseased plants with lime disinfection of the soil.

Scutellaria baicalensis: scutellaria baicalensis moth occurs when available 90% trichlorfon control.

III. Harvesting of Radix scutellariae

The quality of scutellaria baicalensis is the best when it is dug for 3 years. The age should not be too short or too long. If the age is too long, it will produce black heart and affect the quality. Harvest in autumn leaves wither after the general harvest in late September for the best. When the local upper stem leaves wither, they should be planed and harvested. Because the taproot is deeply buried, they should be carefully dug to avoid cutting off the taproot or damaging the outer skin, so as not to cause yield reduction and commodity quality decline. Carefully dig the whole root with tools, remove the soil, cut off the reed head while fresh, trim the fibrous root; cut off the lateral root and fibrous root when it is 70 to 80 percent dry, stack it for 1~2 days, make it regain moisture, and then spread it out for drying; dry it repeatedly until it is completely dry, straighten the root, tie it into small bundles, and then use it for medicinal purposes.
