Detailed explanation of Paris polyphylla var. yunnanensis cultivation techniques, master all the key points of cultivation management
Seed propagation method: sow in early spring from March to April; after sowing, cover with about 3 cm of fine soil, then cover the seedbed surface with grass and water to keep it moist. When seedlings emerge, remove the covering grass and build a shade shed; when the seedlings have grown 7 leaves, transplant and establish them in autumn from October to November or in early spring from March to April; rhizome propagation method: cut from the stem tip at the 3rd to 5th node from the top as seed roots, and likewise plant at a plant spacing of 10-15 cm and a row spacing of 15-20 cm.
1. Seed propagation method
When the seeds mature from August to October, harvest them and mix them with moist sand for storage, or sow them immediately after harvesting. Those stored in moist sand are sown in early spring from March to April of the following year; after sowing, cover with about 3 cm of fine soil, then cover the seedbed surface with grass and water to keep it moist. After sowing, in places with higher temperatures the seedlings emerge in the following spring, while in places with lower temperatures they emerge only in the third spring. When seedlings emerge, remove the covering grass and build a shade shed. After emergence, continue cultivating the seedlings for 2-3 years; when the seedlings have grown 7 leaves, transplant and establish them in autumn from October to November or in early spring from March to April.
2. Rhizome propagation method
After the plants wither in late autumn or before budding in early spring, dig up the rhizomes and cut from the stem tip at the 3rd to 5th node from the top as seed roots, and likewise plant at a plant spacing of 10-15 cm and a row spacing of 15-20 cm. For establishment, it is best to make full use of the space under walnut forests, which not only uses the land resources under the forest but also satisfies the cool, shady and moist environmental conditions that Paris polyphylla prefers, benefiting its growth.
