How long is the growth cycle of Codonopsis pilosula?

Introduction to the growth of Codonopsis pilosula

Codonopsis pilosula growth rate

Codonopsis pilosula growth process: Codonopsis pilosula is suitable for planting in spring. It usually sprouts in March and April. In mid-June, the plant height is 10-15 cm. From mid-June to mid-October, it enters a rapid growth period. The above-ground part will wither in late October and then enter a dormant period.

The growth rate of Codonopsis pilosula is slow.

Codonopsis pilosula growth cycle management

The yield of Codonopsis pilosula is affected by the variety and planting method, and the good yield per mu is 300 to 400 kilograms.

Temperature management: Codonopsis pilosula likes a mild, cool, humid and sunny environment. It begins to sprout when the temperature is between 3 and 7 degrees, and emerges at 6 to 8 degrees. The plant grows fastest when the average daily temperature is 18 to 20 degrees. The most suitable vernalization temperature is 0 to 5 degrees, and the highest temperature cannot exceed 30 degrees to avoid growth inhibition.

Fertilization management: Before planting Codonopsis pilosula, you can apply base fertilizer, such as manure or compost, superphosphate. The seedlings grow slowly, so a small amount of topdressing or no topdressing can be applied. If fertilizer is applied, urea, human feces and urine, etc. Remember not to apply raw fertilizer or concentrated fertilizer.
