Tuber propagation is generally used in production, reproduction is relatively large, and simple
When the tuber of manna is propagated, the rhizome should be dug from the ground. Generally, the thick white rhizome should be selected and cut into small sections for planting. Generally, each hole is planted with 2 - 3 sections. Pay attention to cover the soil after planting, and water will be poured after compaction.
Generally planted in winter, in the second year of spring seedlings, spring planting, seedlings are faster.
Manna seeds can also be propagated by sowing. When sowing, the seeds are harvested, and then sown between March and April in spring.
When sowing, we usually take the way of row sowing, and sow the seeds into the soil, then pay attention to cover the soil, and the soil is slightly compacted.
The germination rate of manna seed is still very high, generally can reach more than 50%, keep the temperature at 17 ℃ - 20 ℃, about 10 days can sprout.
