Planting method of Baiyao in Yunnan

The main ingredient of Yunnan Baiyao is Panax notoginseng, which needs to be planted with seeds full of particles and free of diseases and insect pests, which can be planted in mountainous areas with high terrain and a certain slope, and the width of the border is about 1.5m, and the basic fertilizer can be applied with potash fertilizer, compound fertilizer and farm manure, and then planted according to the density of plant spacing of 30cm and row spacing of 22-30cm, which can be watered every 4 days or so, and topdressing in time. In the later stage, trichlorfon and mancozeb can be used to control diseases and insect pests.

First, planting time

The main ingredient of Yunnan Baiyao is Panax notoginseng, generally in the southern part of China, it can be planted in November-December in winter, while in the northern part of China, it can be planted in March-April in spring, and the planting time is mainly determined according to different regions.

2. Selection of species and soil preparation

The main results are as follows: 1. Full-grained, pest-free and robust seeds can be selected for sowing, and they can be planted in mountainous areas with relatively high terrain, and they also need to have a certain slope, which is convenient for later drainage and can be planted in loose black soil. this kind of soil has good permeability and high soil fertility.

2. The width of the border is generally about 1.5m. After leveling the border, 30 jin of potash fertilizer, 50 jin of compound fertilizer and 5000 jin of farm manure are sprinkled, and finally wait for sowing.

Third, sowing and transplanting

1. If the seeds are harvested by yourself, then the seeds need to be soaked and disinfected. During this period, the outer pericarp of the seeds can be rubbed off, put into a basin containing multi-fungus solution, soak for about 20 minutes, fish out and drain water, put them into plant ash and stir evenly, so that the seed epidermis is evenly stained with plant ash, and then put at a suitable temperature for germination, and so most of the seeds emerge and sow.

2. If the seeds are bought from the market, they can be sowed directly. The way of sowing is a little bit sowing and strip sowing. You can sow seeds according to the distance of each plant interval of 30cm and each row interval of 22-30cm, waiting for about 5 days to grow sprouts. At this time, you can transplant the sprouts in the field. Where the growth is too dense, you can appropriately pull out some of them and transplant them to other places, and the density of transplanting is the same as that of sowing.

IV. Fertilizer and water management

1. Panax notoginseng needs a lot of water in the growth process, so it can be planted in the mountains with sufficient water sources, and it can be watered every 3-5 days, which is beneficial to maintain the soil moisture, while in the rainy season, it needs to be drained in time. As the planting terrain is sloping, drainage is relatively simple, as long as the ditch in the field is dredged, the stagnant water can be discharged automatically.

2. The whole growing period of Panax notoginseng can be divided into three stages. generally speaking, three times of fertilizer need to be applied, and the first fertilization can be applied around March, that is, the seedling growing stage of Panax notoginseng. 5000 jin of compound fertilizer can be applied per mu, and the second fertilization is the stage of raising seedlings of Panax notoginseng. About 3000 jin of compound fertilizer can be applied per mu, and the third time is in the root-promoting period of Panax notoginseng. It needs to be watered after each fertilization to prevent fertilizer damage.

V. Prevention and control of diseases and insect pests

1. Aphids and red spiders: trichlorfon or imidacloprid solvent can be used for control.

2. Yellow rust and powdery mildew: Bordeaux solvent can be used for spraying.

3. Epidemic disease: you can use 500-600 times liquid 70% mancozeb spray, spray once every 3 days, spray 3 times in a row.

4. Blight: 1000-fold solution of 70% methyl topiramate can be used for foliar spraying, once every 2-3 days, generally 2 times can be cured.
