1、 Curing method

1. Soil: plant Polygonatum in sandy loam or loose soil with good water retention. Because Huangjing likes cloudy and humid soil, it is necessary to apply some farm fertilizer before planting, and then turn over the cultivated land, which is conducive to promoting the absorption of Huangjing nutrients after planting

2. Moisture: always keep the soil moist because it is afraid of drought. In rainy days, it is necessary to drain water to avoid excessive water and ulceration of its roots

3. Nutrients: generally, chicken, duck, pig manure and human manure are used for fertilization, and some farm manure can also be applied appropriately. During the growth period, they should often pull grass and cultivate, and shallow tillage can be used

4. Sunshine: cultivation should choose a cool and shady place. It likes humidity and avoids places with strong sunlight. Strong sunlight will sunburn its branches and leaves

2、 Breeding skills

1. Pruning: in order to improve the yield of polygonatum, some flowers should be removed in time in the flowering season. The flowers of Polygonatum will consume the nutrients of Polygonatum and affect the growth of rhizomes of Polygonatum. Picking some flowers in time can promote its growth

2. Reproduction: seeds are generally used for reproduction. In August, choose strong and plump seeds and store them in a pit with a moist shade of 30 cm. Wait until the next spring to sow, water and cover the film, and transplant the seedlings after they grow

3、 Diagnosis and treatment problems

1. Leaf spot disease: leaf spot disease often occurs during its growth. At this time, it only needs to use dysen zinc wettable powder mixed with water for spray control

2. Rotten roots: the reason for rotten roots is that there is water in the soil. If there is no timely drainage, it will cause rotten roots of polygonatum, so it must be drained in time

4、 Other issues

1. How to spend the winter: if potted plants can be moved to indoor breeding, try to put them in a place with shade and ventilation, otherwise it will deteriorate its growth state

2. Whether it can be eaten: it can be eaten, but not too much. Everything has advantages and disadvantages. Eating a small amount can have a large amount and will have the opposite effect
