Planting and growth conditions of Codonopsis pilosula

Codonopsis pilosula can be planted in sandy loam with strong permeability, strong water storage, good permeability, loose soil and rich organic matter, and the suitable water temperature for seed soaking is about 40 ℃, and it can be planted from mid-March to early April, or from mid-October to early November, and the planting row spacing is about 30cm, and the plant spacing is 10-15cm. When the seedlings grow to 15cm, fertilize, and build scaffolds when the seedlings grow to about 30cm.

I. planting conditions

The main results are as follows: 1. The planting conditions of Codonopsis pilosula are mainly light, soil, temperature, humidity, nutrients and climate. Codonopsis pilosula is suitable to grow in warm, humid and cool climatic conditions, and likes shade and fears direct light, but it also needs appropriate light.

2. The sandy loam with good permeability, strong permeability, strong water storage, loose soil and rich organic matter should be selected.

2. Seed treatment

1. Before planting Codonopsis pilosula, the seeds can be treated by soaking seeds. The suitable water temperature is about 40 ℃ when soaking seeds. It is appropriate to soak until the water temperature is not hot. When soaking seeds, continuous stirring is needed.

2. To put the seeds into the gauze bag, rinse the seeds with clean water for about 3 times, and then put them on the sand pile to accelerate germination. Every 3-4 hours, the seeds need to be drenched in a gauze bag with a temperature of about 15 ℃, usually waiting for about 7 days to sow.

Third, planting time and density

1. In the process of planting Codonopsis pilosula, the time of raising seedlings is usually about one year, and then the planting time is usually in spring and autumn, which is from mid-March to early April, or from mid-October to early November.

2. When planting, it can be planted according to the density of row spacing of 30cm and plant spacing of 10-15cm.

Fourth, watering and topdressing

1. Watering should be carried out after the seedlings are planted, which is conducive to promoting the growth and development of new roots. After the seedlings are planted and survived, the amount of water will be slowly reduced. In case of continuous rain, it is necessary to dredge the ditch in time for drainage to avoid excessive water accumulation, resulting in Codonopsis pilosula root rot.

2. When topdressing in the later stage of growth, we can choose to apply fertilizer when the seedlings grow to 15cm, and the topdressing is mainly based on manure and urine.

Fifth, build a bracket

Generally, the stems, leaves and vines of Codonopsis pilosula are relatively long, so we can choose to build a support when the seedlings grow to about 30cm, and draw the branches and leaves of Codonopsis pilosula to grow along the bracket, which can maintain permeability in the field, reduce the incidence of diseases and insect pests, and increase yield at the same time.
