Those who live in rural areas generally get to see many different kinds of plants, and plants like Uncaria rhynchophylla are probably not too unfamiliar either. It has certain medicinal effects, with properties that clear heat and calm the liver, and extinguish wind and stop convulsions. So how should Uncaria rhynchophylla seeds be selected now? What propagation methods are there? Next, let the editor tell everyone!

1. How to select Uncaria rhynchophylla seeds?

The Chinese Pharmacopoeia stipulates that the authentic Uncaria rhynchophylla medicinal material is the dried hook-bearing stem and branch of Uncaria rhynchophylla, Uncaria macrophylla, Uncaria hirsuta, Uncaria sinensis, or Uncaria sessilifructus, harvested in autumn and winter, so it is best to choose the above varieties for cultivation. Generally, from mid-October to late November, select mature, large, plump seed balls from superior and robust Uncaria rhynchophylla plants, cut off the fruiting branches with pruning shears, spread them out in a dry, ventilated place to dry in the shade or dry them in sunlight, then seal them in plastic bags and place them in a ventilated, dry place.

2. Propagation methods for Uncaria rhynchophylla seeds

1. Site selection and land preparation

Uncaria rhynchophylla has strong adaptability and is not strict about soil; it can grow normally in ordinary soil, but it grows better in loam with deep soil layers that is fertile, loose, and well-drained. After selecting the site, plow the plot deeply, break up the soil clods, rake it fine, apply base fertilizer, and make beds with a width of 1-1.2 m. For field planting, hillsides or forest areas can be chosen; before planting, dig holes at a row spacing of 3 m, and apply decomposed farmyard manure to each hole as base fertilizer.

2. Propagation methods

Uncaria rhynchophylla can be propagated by three methods: seeds, cuttings, and division. For seed propagation, collect mature seeds in autumn, sow them immediately after collection, open furrows on the bed surface at a row spacing of 12-15 cm, evenly scatter the seeds into the furrows, and then cover with a layer of ash soil and fine soil. For division propagation, do it in spring when the plants are growing; it can be combined with intertillage by digging and injuring the root system to encourage the roots to sprout adventitious buds, and when the young buds grow into new plants, cut them off together with the roots and replant them. Cuttings are generally carried out in early March, which is the flower bud differentiation period; cut 2-year-old branches with buds from the plants, with 2-3 strong buds per node, and insert them as soon as they are cut.

3. Field management

For those propagated by seeds, seedlings emerge in the first spring, so weeds should be removed and the field cleaned in time, while for those propagated by cuttings, after they survive, apply a thin fertilizer once a month. After planting, carry out timely intertillage, weeding, and earthing up. Uncaria rhynchophylla begins to sprout new branches around Qingming, and by the Autumn Equinox the top branches should be cut off to encourage the plant to sprout new branches. After planting, apply a thin fertilizer once every 40 days, and in winter cover with a layer of manure fertilizer to help the plants overwinter.
