1、 Curing method

1. Soil: it has high requirements for soil and is suitable for growing in fertile soil. The soil with deep soil layer is also suitable for its growth. It can be prepared with garden soil + rotten leaf soil

2. Light: Yunnan Yellow essence likes Yin, and it also needs some light during its growth period. The planting of Polygonatum yunnanense is generally selected in the place with half shade and half sun or the place with shade next to the planting place to prevent direct sunlight. But we should also ensure a little astigmatism irradiation, which is very good for its growth

3. Water: Yunnan Polygonatum needs a lot of water for its growth, but it doesn't need a lot of water each time, otherwise it is easy to develop diseases. Regular watering is required during maintenance to keep the soil moist. Yunnan Polygonatum has different requirements for water in different growth cycles. You can pour more water in the growing season, but you should pay attention to water control in winter

4. Temperature: Yunnan Polygonatum grows well in the annual climate of 15-25 ℃, which is not suitable for growing in hot environment

2、 Breeding skills

1. Seed storage: its seeds mature around August. When it matures, you need to collect them and choose a fuller sand reservoir. The method of sand storage is to mix the seeds and sand in the ratio of 1:3 and put them in the pit in the shade. Then spray water in time to keep the sand moist

2. Timely pruning: if there are poorly growing leaves on the plant, they should be cut off in time, so as not to affect the growth of the whole plant

3、 Diagnosis and treatment problems

1. Disease: its main disease is leaf spot, which often occurs in summer and autumn. The diseased leaves will turn white in the middle and grow large brown spots on the periphery. In severe cases, it will affect the photosynthesis of mating leaves and cause the death of the whole plant. In the early stage of discovery, it is necessary to spray 65% zineb 500 times in time for treatment

2. Insect pests: its main insect pests are grubs, which mainly harm the roots and stems of plants. Adults can be lured by light or sprayed with 800 times of 90% crystal trichlorfon

4、 Other issues

1. Whether it can be cultured indoors: it can be cultured indoors. During normal maintenance, try not to be exposed to the sun, just a little astigmatism. We should also maintain the circulation of air in the maintenance environment

2. Harvest time: if it is cultivated in a warm climate area, it can be harvested after 2-3 years of management. The harvest time should be in the spring and autumn. The products harvested in these two times will be of high quality
