Where is the traditional Chinese medicine scutellaria cultivation technology? Also please net friend help introduce the cultivation net collated scutellaria planting technology, listed above for net friend's reference. 1. Suitable conditions for the growth of scutellaria baicalensis: scutellaria baicalensis can grow in the annual average temperature of 4-10℃, the annual accumulated temperature of ≥10℃ of 2500-4000℃, and the frost-free period of 120-180 ℃. Deep soil layer, good drainage, loam, sandy loam or humus loam, flat, gentle slope can be, there are better irrigation conditions, young fruit trees and sunny wasteland can also be. Source of seed: There is no breed in real production sense at present, all seeds are domesticated and propagated from mixed population seeds collected from wild resources. 2. Treatment and sowing method of scutellaria seed gum seed: (1) The seed treatment method of scutellaria baicalensis: soak the seeds in warm water of 40--45℃ for 5-6 hours or tap water at room temperature for 12-24 hours, take them out and air them for a while, put them at about 20℃ for moisture preservation and germination, and sow them when some seeds are cracked and germinated. (2) Sowing method of scutellaria baicalensis: The sowing time of scutellaria baicalensis is generally in the middle of April, when the ground temperature of 5 cm underground is stable at 15℃, when the soil moisture is guaranteed; generally, the spring sowing is in March to April, and the autumn sowing is in September to October. Sowing methods for dissemination, dibbling, drilling three kinds, generally shallow should not be deep, so as not to bud thin weak. General sowing rate Dry seeds 0.8-1 kg/mu After sowing, scutellaria baicalensis was covered with fine wet soil about 1cm, and pressed and covered the ground in due time. Keep soil moist until emergence. 3. Field management of scutellaria baicalensis: (1) intertill weeding 3-4 times in the first year, and 1-2 times in the second year. (2) Thinning and fixing seedlings When the seedling height is 5-7cm, the thinning and fixing seedlings are carried out according to about 60 seedlings per square meter. (3) In the first year of topdressing, after seedling setting, and in the spring of each subsequent year, urea, diammonium phosphate and potassium sulfate were applied 75-12.5kg/ha each time before ridge closure. After mixing the three fertilizers, they were applied in furrows and covered with soil and fertilizer. (4) Suppress the squatting seedling stage. In the afternoon of sunny day, gently step on the ridge with feet or gently press the above-ground part of scutellaria baicalensis with stone and wood rollers. Press once every 3-5 days and press it three times. (5) Cut the flowering branches to the field without harvesting seeds. Before flowering after budding, choose sunny morning and cut off the flowering branches in batches. 4. Prevention and control methods of diseases and insect pests of scutellaria baicalensis: (1) Root rot control During the growth period, tilling and loosening the land in time, and draining in time to prevent waterlogging in rainy season. Regulate soil moisture and improve soil ventilation. Remove diseased plants in due time and disinfect diseased acupoints with 5% lime water. (2) Control of stem-base rot: On the basis of integrated agricultural control of root rot, 600-800 times solution of 50% carbendazim and 80% manineb 1:1 was sprayed at the early stage of disease. (3) Spray 50% carbendazim wet powder 1000 times solution at the initial stage of disease. 5. Method for harvesting and processing Radix scutellariae: (1) Growth period Chengde and northern cold areas to grow 2-3 years to dig roots is appropriate. (2) The picking season is spring, and the sunny day is selected after the emergence of scutellaria baicalensis. (3) Digging method: plough or manual pick digging, avoid main root damage during the day, remove stems and leaves in time, shake clean soil, and dry in time. (4) Drying processing Separate the root of scutellaria baicalensis according to large, medium and small size, and select sunny, ventilated and dry places to dry. The root tips and fine lateral roots that were knocked down were collected separately. Avoid washing or raining in the process of drying, otherwise, the roots will turn green and black. (5) Yield of commercial dry medicinal materials is 150-200 kg/mu for biennials and 300-400 kg/mu for triennials. (6) Mastering the season and method of collecting herbs is related to the improvement of the quality of medicinal materials. My county planting scutellaria baicalensis, some people eager to harvest 1 year, according to experts: in fact, 1 year scutellaria baicalensis, its baicalein content of about 7%, manufacturers less than pharmacopoeia 9% standard, 2-3 years old baicalein content up to 13-18%, so in addition to pay attention to the harvest season, but also pay attention to the growth time of medicinal materials.
