How to carry out field management of Scutellaria baicalensis? Latest technical key points
Scutellaria baicalensis, also called mountain tea root, is a perennial herbaceous plant of the Lamiaceae family. It is distributed throughout various regions of China, mainly concentrated in the northwest, southwest and other areas. Its planting area is also very extensive. In the planting process, if you want to ensure the yield and quality of Scutellaria baicalensis, the most important thing is to do a good job in field management. So how should field management be carried out when planting Scutellaria baicalensis? Below, the editor brings you the field management techniques for Scutellaria baicalensis. Let's take a look!
1. Thinning and final singling of seedlings
When the Scutellaria baicalensis seedlings grow to about 6 cm, the thinning work should be done well. The purpose is to ensure that each robust Scutellaria baicalensis seedling has sufficient growing space. When thinning, control the spacing of seedlings at about 7 cm and then final-single them. The work of thinning and final singling of seedlings is very important for the growth of Scutellaria baicalensis. It is directly related to the growth capacity and yield of Scutellaria baicalensis in the middle and later stages. When thinning and final-singling, pay attention to filling missing seedling holes with robust seedlings of the same growth. Then when transplanting, pay attention to transplanting with soil. After transplanting, water thoroughly to settle the roots and promote the growth of Scutellaria baicalensis.

The growth capacity of Scutellaria baicalensis seedlings is relatively weak, and the growth speed is not fast, so intertillage and weeding should be done well during the seedling stage. Regular intertillage can not only effectively remove weeds from the soil and prevent them from robbing the growth nutrients of Scutellaria baicalensis seedlings, but also improve soil permeability and enhance soil quality. In the first year of planting Scutellaria baicalensis, weeding should be done at least about 3 times until the rows close, then stop weeding. Then in the following years, loosen the soil once each time before the green-up stage of Scutellaria baicalensis. After the green-up stage, weed appropriately according to the weeds and the growth of Scutellaria baicalensis until the rows close.
3. Water and fertilizer management
Scutellaria baicalensis has a relatively large demand for nutrients. When planting Scutellaria baicalensis, fertilizer should be applied in a timely manner, mainly nitrogen, phosphorus and potassium fertilizers, which can effectively increase the yield of Scutellaria baicalensis. Controlling the ratio of nitrogen, phosphorus and potassium fertilizers well can ensure the normal growth of Scutellaria baicalensis. Pay attention to the amount of chemical fertilizer and do not overapply chemical fertilizer to prevent fertilizer damage. Also, nitrogen fertilizer should not be overapplied or applied alone, to prevent excessive nitrogen fertilizer from causing excessive vegetative growth of Scutellaria baicalensis and reducing yield. Then, before the Scutellaria baicalensis seedlings emerge, keep the soil moist. After final singling, control watering; the water should not be too much. Observe the soil moisture condition. When the soil is too dry, pay attention to appropriate watering, but in the rainy season or when watering too much, drain in time to avoid root rot and dead seedlings and to prevent pests and diseases.
4. Mulching with straw and removing flowers
After each intertillage and weeding, cover about 2 cm of rice straw between the rows of Scutellaria baicalensis. It is best to chop the rice straw to improve the soil's moisture and fertilizer retention capacity. Avoid soil drought, prevent soil compaction, control soil temperature, and ensure normal root growth. Then, for some Scutellaria baicalensis fields not kept for seed, after the buds appear, cut off the flowering branches to avoid excessive consumption of nutrients by the aboveground part, which would rob nutrients from the underground roots and hinder root growth. Concentrate nutrients in the plant roots to increase the yield and enhance the quality of Scutellaria baicalensis.
The above is a brief introduction to how to carry out field management of Scutellaria baicalensis. We also need to do a good job in pest and disease control so as to ensure more robust growth of Scutellaria baicalensis, increase yield, and protect our own economic benefits from planting. That is all for today's introduction. This article is for reference only and we hope it can help everyone!
