How to carry out field management of Scutellaria baicalensis? A full analysis of the technical key points
Scutellaria baicalensis, also called "shancha root", is a perennial herbaceous plant of the Lamiaceae family. It is distributed throughout China, mainly concentrated in regions such as the northwest and southwest. Its planting area is also very wide. In the process of cultivation, the most important thing for ensuring the yield and quality of Scutellaria baicalensis is doing a good job of field management. So how should field management be carried out when growing Scutellaria baicalensis? Below, the editor brings you the field management techniques for Scutellaria baicalensis. Let's take a look!
1. Thinning and final thinning of seedlings
When the Scutellaria baicalensis seedlings grow to about 6 cm, the thinning work should be done well, with the purpose of ensuring that every robust Scutellaria baicalensis seedling has the growing space it needs. When thinning, control the spacing between seedlings at about 7 cm and finalize the stand. The work of thinning and finalizing 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 finalizing seedlings, pay attention to filling gaps where seedlings are missing with robust seedlings of the same growth. Then, when transplanting, pay attention to transplanting with soil, and after transplanting water thoroughly to settle the roots, promoting the growth of Scutellaria baicalensis.
2. Intertillage and weeding
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 in 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, and stopped after the rows close. Then in the following years, loosen the soil once each time before the green-returning stage of Scutellaria baicalensis. After the green-returning stage, weed appropriately according to the growth of weeds and 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 fertilizers such as nitrogen, phosphorus and potassium, 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 used; do not overapply chemical fertilizer, to prevent fertilizer damage. Also, nitrogen fertilizer should not be overapplied or applied alone, to prevent excessive nitrogen from causing excessive vegetative growth of Scutellaria baicalensis and reducing yield. Then, before the Scutellaria baicalensis seedlings emerge, keep the soil moist. After finalizing the seedlings, control watering; moisture should not be excessive. Pay attention to observing soil moisture. When the soil is too dry, water appropriately, but in the rainy season or when watering too much, drain promptly to avoid root rot and dead seedlings, and to prevent pests and diseases.
4. Mulching with straw and flower removal
After each intertillage and weeding, cover the space between the rows of Scutellaria baicalensis with about 2 cm of rice straw. It is best to chop the rice straw to improve the soil's ability to retain moisture and fertilizer. Avoid soil drought, prevent soil compaction, control soil temperature, and ensure normal root growth. Then, for some Scutellaria baicalensis fields where seed is not to be kept, after Scutellaria baicalensis buds, 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, increase the yield of Scutellaria baicalensis, and enhance quality.
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 the prevention and control of pests and diseases so as to ensure more robust growth of Scutellaria baicalensis, increase yield, and protect our own economic benefits from cultivation. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
