Yuanzhi can also be called grass and chicken legs. It is a perennial herb of Polygalaceae, mainly produced in Shanxi. Yuanzhi likes a cool climate, is resistant to drought, cold, and is afraid of water, and has high requirements for soil moisture. The plant height is 25-45 cm, the flowering period is from July to August, and the fruiting period is from August to September. Today, Xiaobian talks about the cultivation techniques of Chinese herbal medicines, as follows. First, the selection of ground preparation fertilizer Choose a plot with good sun and drainage capacity, and turn the plot deeper by 25cm. Then apply 2500kg of fully-fertilized farmyard manure and 50kg of diammonium phosphate as base fertilizer per acre, and then flatten the plot in the whole. Second, seed treatment Seed treatment before planting, planting into water or soaking in 0.3% potassium dihydrogen phosphate aqueous solution for 2 days before sowing, then remove and drain, and add a small amount of fine sand equivalent to 3-4 times the seed volume. Water, so that the fine sand is mixed with the seeds evenly when it is not in the water, and then sown after being placed for 1 day. Third, sowing 1, live When broadcasting the Yuanzhi, there is no need for seed treatment. The sowing time can be selected from May to August, but it is better to plant in July-August. In the case of a good bottom, the shallow ditch is spread at a distance of 20 to 25 cm and 2 cm deep, or by a row spacing of 20 cm and a plant spacing of 15 cm. 4-5 seeds are planted per hole, and the planting amount per acre is about 2-3 kg. Covering the soil after sowing, the soil cover thickness is not suitable for seed, after gently covering the soil, it can be emerged after about 10 days. 2, seedling transplanting In March, the small arch shed was used to raise seedlings. Of course, it was also possible to raise seedlings in July. The treated plants were sown in shallow trenches with a row spacing of 10 cm and a depth of 2 cm, and the soil was covered after sowing. When the seedling height is 5 cm, the seedlings are 3 cm apart. Fourth, field management 1. Live field, Yuanzhi should strengthen management after emergence for 1 month, and remove weeds in time. When the seedling height is 5-7cm, the seedlings should be fixed according to the plant spacing of 3cm. 2, transplanting the field, the initial watering should be properly maintained to keep the soil moist; in the early stage of growth, weeding should be carried out in time, and watering should not be carried out in the later stage of growth. 3. The live fertilization and transplanting of the field are basically the same. After sowing or transplanting and planting, in the period from July to August of that year, 800 kg of human excrement, 4 kg of urea and 5 kg of potassium chloride were applied per mu of land; 500 kg of human excrement was applied per mu of land in the same year; In the month, 25kg of cake fertilizer per acre, or 6kg of urea, 15kg of superphosphate, 6kg of potassium chloride; foliar topdressing at flowering stage, 0.6kg of potassium dihydrogen phosphate per acre is made into 0.3% aqueous solution, divided into 3 times in sunny afternoon Spray after 4 o'clock, spray once every 10-12 days. 4. The main pests and diseases of Polygala are root rot and aphids; root rot: 50% carbendazim WP 1000 times spray can be used for prevention and control at the beginning of the disease; mites: 40% elegan emulsifiable concentrate 2000 times can be sprayed. V. Harvesting Underground root harvesting: picking in 2-3 years after sowing, mining in the late autumn and early spring is appropriate; seed harvesting: in July-August, the soil between the Yuanzhi line will be leveled, and the seeds will be harvested after the seeds are matured. Or manually harvesting. For the wonderful pictures and popular comments of Chinese herbal medicines, you may be interested in the following recommended contents. Welcome to read.

The COVID-19 Antigen Test Cassette is immunoassay based on qualitative membrane strip for the detection of COVID-19 antigen in anterior nasal swab
specimen. In this test procedure, anti-COVID-19-N antibody is immobilized in the test line region of the device. After an anterior nasal swab specimen is placed
in the specimen well, it reacts with anti-COVID-19-N antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized anti-COVID-19 antibody. If the specimen contains COVID-19 antigen, a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain COVID-19 antigen, a colored line will not appear in this region, indicating a negative result.To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
