How to choose land and make beds for Asarum planting? Detailed explanation of key technical points
Asarum seedlings have weak emergence ability and strict soil requirements, so understory humus soil is mostly chosen as the seedling field. Humus soil is moist, well structured, and highly aerated, suitable for Asarum seedling growth. Generally, when raising seedlings on humus soil, the emergence rate can reach more than 90%. Farmland soil should not be used for Asarum seedling cultivation; the physical and chemical properties of farmland soil are inferior to humus soil, it is prone to compaction, seedlings are not easy to emerge after sowing, sprouts are prone to drying, and even if they emerge, growth is not easily robust.
The specifications of the seedling field beds and the requirements for light transmittance are the same as those of the seed field. The seedling beds should be prepared before seed collection so that sowing can be carried out in time.
