1、 Curing method

1. Soil: Xu Changqing has no strict requirements on soil. Generally, soil can grow. Sandy soil rich in humus is the most suitable for cultivating Xu Changqing

2. Moisture: when watering, the amount of water can be appropriate, not too much. If there is water stored in the basin, its roots will rot and the plant will be damaged, which will affect its normal growth

3. Fertilize the whole soil evenly, so as to improve the yield of nutrients

4. Light: it likes to grow in a sunny, mild and refreshing environment. Sufficient sunshine can make it grow more robust

2、 Breeding skills

1. Pruning: when the seedling grows, the branches and leaves should be properly pruned to prevent the complex branches and leaves from affecting the absorption of nutrients during the growth period. The weak leaves should be thinly cut off, and the soil should be loosened and weeded to avoid

2. Breeding: seeds are often used for breeding, and the planting time is about March. Select mature and robust seeds and mix them with plant ash before sowing. Then sprinkle it into the soil, spray some water to moisturize, and new seedlings can grow in about 15 days

3、 Diagnosis and treatment problems

1. Root rot: poor drainage will cause root rot, and the roots will be black during the onset of root rot. Improper control will affect the growth of Cynanchum paniculatum, which can be solved by dilution and spraying with genfuling

2. Rotten roots: when the weather is hot and dry, it should be properly hydrated. However, the amount of water should not be too much. When it rains, the accumulated water in the soil should be drained in time. If the drainage is improper, it will cause retting and rot

4、 Other issues

1. How to harvest and store: remove the soil and impurities during the harvest period and dry them into a semi dry state. Then tie it into small handfuls, air it again until it is dried, and finally put it in a cool and dry place

2. Whether it can be exposed to rain: during the breeding period, it should not be washed by rain. If the rain drops into the basin and the drainage is not timely, it will cause root rot, so proper shielding can save a lot of complicated things
