What is the price of Scutellaria baicalensis seeds? Detailed planting methods
Scutellaria baicalensis is a perennial herbaceous plant of the genus Scutellaria in the Lamiaceae family, also known as Shancha root, Tujincha root, etc. It often grows on sunny grassy slopes and abandoned wasteland. It can be planted in most provinces and regions in northern China and has very high cultivation value. Its roots are used as medicine and have effects such as clearing heat and drying dampness, purging fire and detoxifying, stopping bleeding and calming the fetus. Let us take a look at Scutellaria baicalensis seed prices and planting methods together!
How much do Scutellaria baicalensis seeds cost?
The price of Scutellaria baicalensis seeds is about 120 to 200 yuan per jin, but prices vary greatly depending on variety, quality and purchase quantity. When planting Scutellaria baicalensis, the sowing rate is 1 to 2 jin per mu. Because the seeds are small, to avoid uneven sowing, they can be mixed with 5 to 10 times fine sand and stirred evenly before sowing. At the same time, water promptly after sowing and keep the surface soil moist regularly. Seedlings will emerge in about 15 days. After emergence, thin out the dense and weak seedlings. The yield is generally about 300 to 400 jin per mu.
Sowing methods for Scutellaria baicalensis
1. Direct seeding propagation method: Seed propagation of Scutellaria baicalensis is mainly by direct seeding. The root system is straight, there are few root branches, the commercial appearance quality is good, and it saves labor. It is mostly carried out in spring. Generally, sowing is done when the soil temperature at 5 cm underground is stable at 12 to 15°C. In northern regions, it is mostly around early to mid-April.
2. Seedling transplanting method: Seedling transplanting of Scutellaria baicalensis can save seeds, extend the growth time, and help ensure a full stand of seedlings, but it is relatively labor-intensive. At the same time, the main root is shorter, there are more root branches, and the commercial appearance quality is poor. It is generally used when seeds are expensive or when direct seeding in dry land lacks water and it is difficult to emerge and preserve seedlings.
Sowing methods for Scutellaria baicalensis
1. Seed treatment: Soak Scutellaria baicalensis seeds in warm water at 40 to 45°C for 5 to 6 hours, or soak them in tap water at room temperature for 12 to 24 hours. Remove them and let them dry slightly, then place them at about 20°C with moisture retention to promote germination. When some seeds crack and sprout, they can be sown.
2. Sowing time: Scutellaria baicalensis is generally sown in spring from March to April, and in autumn from September to October. When soil moisture is guaranteed, it is best around mid-April when the soil temperature at 5 cm underground is stable at 15°C. The sowing methods are broadcast sowing, dibbling and drilling, and it is better to sow shallowly rather than deeply.
3. Sowing method: For Scutellaria baicalensis, use 1 to 2 jin of seed per mu. After sowing, cover with fine moist soil 2 to 2.5 cm deep. At the same time, press down in a timely manner and cover the ground, keeping the soil moist until seedlings emerge.
Planting methods for Scutellaria baicalensis
1. Thinning and final singling: When Scutellaria baicalensis is directly sown with seeds, when the seedlings grow to 4 cm high, thin out the overly dense and weak small seedlings, and set the plants at a spacing of 10 cm. Seedling beds do not need thinning.
2. Cultivation and weeding: After Scutellaria baicalensis seedlings emerge, loosen the soil and weed in a timely manner, and properly earth up around the seedlings while loosening the soil, keeping the soil loose and free of weeds. Weeding is needed 3 to 4 times a year.
3. Reasonable fertilization
① Fertilization: When Scutellaria baicalensis seedlings are 10 to 15 cm high, apply fertilizer once, with an application rate of 1500 to 2000 kg of human and livestock manure water per mu. From the end of June to early July, apply 20 kg of superphosphate and 5 kg of urea per mu, applying them in furrows between rows, then cover with soil and water.
② Topdressing: For Scutellaria baicalensis harvested the next year, after the plants wither, open furrows between rows and apply 2000 kg of decomposed barnyard manure, 20 kg of superphosphate, 5 kg of urea and 150 kg of plant ash per mu, then cover with soil and level it.
4. Drainage and irrigation: Scutellaria baicalensis is drought-tolerant and afraid of waterlogging. If there is standing water in the field or too much rain, attention should be paid to drainage during the rainy season. The field must not have standing water, otherwise the roots are prone to rot. In cases of severe drought or after topdressing, appropriate watering may be done.
5. Removing flower buds: Before Scutellaria baicalensis produces inflorescences, cut off the flower stems, which can reduce nutrient consumption, promote root growth and increase yield.
6. Pest and disease control
① Leaf blight: Clean the field, spray 1:1:200 Bordeaux mixture in the early stage, or use 50% carbendazim 1000-fold solution for control.
② Root rot: Pay attention to drainage, practice crop rotation, promptly pull out diseased plants and burn them, and disinfect the soil where diseased plants were with lime.
③ Scutellaria baicalensis dance moth: When the Scutellaria baicalensis dance moth occurs, 90% trichlorfon can be used for control.
