How can Scutellaria baicalensis be managed effectively during cultivation?
How should Scutellaria baicalensis be managed well during cultivation? Please provide guidance. For growing Scutellaria baicalensis, you can refer to the following methods for management: 1. Management before emergence: Regardless of the propagation method, the soil should be kept moist from planting until emergence to promote seedling emergence. 2.

How should Scutellaria baicalensis be managed well during cultivation? Please provide guidance.
For growing Scutellaria baicalensis, you can refer to the following methods for management:
1. Management before emergence: Regardless of the propagation method, the soil should be kept moist from planting until emergence to promote seedling emergence.
2. Thinning and final thinning: Combined with intertillage and weeding, Scutellaria baicalensis should be thinned, replanted, and finally thinned in a timely manner; after the seedlings are uniform, overly dense areas should be thinned promptly; when the seedlings are 5 cm tall, final thinning should be done at a plant spacing of 10 cm, and replanting should be carried out in areas with missing seedlings. Replanting should involve transplanting with soil and timely watering to promote survival.
3. Intertillage and weeding: For direct sowing or seedling transplanting, the seedlings grow slowly. From emergence to canopy closure, loosen the soil and weed 3 to 4 times. The first time is after the seedlings are uniform, and intertillage should be shallow to avoid burying the seedlings; the second time is after final thinning, and loosening the soil should also be shallow. After that, based on weed growth, carry out intertillage and weeding another 1 to 2 times. During the seedling stage, Scutellaria baicalensis plants are weak, so when weeding, weeds close to the seedlings should be pulled by hand. In each following year, before green-up in spring, the field should be cleaned and the soil loosened by raking; from green-up to canopy closure, intertillage and weeding should still be carried out 2 to 3 times to avoid affecting the growth of Scutellaria baicalensis.
4. Topdressing: During the growing period of Scutellaria baicalensis, topdressing should be done 1 to 2 times each year. Applying nitrogen, phosphorus, and potassium fertilizers together gives the best results. In the north, under conditions of medium to low fertility, the total amount applied over 3 years should be 13.2 to 15.5 kg of pure nitrogen per mu, 6.3 to 7.4 kg of available phosphorus, and 10 kg of potassium sulfate. The number and timing of applications are as follows: phosphorus fertilizer and potassium fertilizer are each used as base fertilizer or applied in two equal split applications after final thinning and after green-up in the second year; nitrogen fertilizer can be applied after final thinning and after green-up in the second and third years, in 3 applications, with the application ratio roughly 30%, 30%, and 40%.
5. Drainage and irrigation: After emergence, if soil moisture is insufficient, water once before and after final thinning. After that, if there is no drought, generally do not water again, to help control seedling growth and promote rooting. In other seasons and in later years, if there is severe drought or if soil moisture is insufficient at the time of topdressing, appropriate watering should also be done. Scutellaria baicalensis is afraid of waterlogging, so during the rainy season, accumulated water in the field should be drained promptly to avoid root rot.
