The invention discloses a breeding method for
polygonatum cyrtonema seeds. The method comprises the steps: a. seed collection and storage: picking mellow
polygonatum cyrtonema fruits,
rubbing off coats, carrying out rinsing, and carrying out shade
drying; selecting a leeward and shady place, digging a cellar, placing wooden boxes in the cellar, placing fine sand with the thickness of 3cm in each
wooden box, then, spreading the
polygonatum cyrtonema seeds, and then, laying fine sand with the thickness of 1cm; and then, covering the wooden boxes with sunshade nets, and then, carrying out covering with rice straws; b. seed
germination hastening: taking out the cellared seeds, and screening out superficial fine sand; soaking the sterilized seeds with constant-temperature water, then, loading the soaked seeds to the wooden boxes, and possibly using
cotton cloth or rice straws as
bedding; adopting temperature-changed and temperature-controlled
germination hastening, and keeping wet; and carrying out
sowing after
white spots emerge on seed coats; and c.
sowing: digging up sterilized soil to be loose, allowing the soil to be fine, then, applying
farmyard manure, then, carrying out
sowing, covering the seeds with a layer of fine soil after sowing, and carrying out spray watering according to
soil humidity; and then, covering surfaces with a layer of
firewood for
water retention, heat preservation and
weed control. According to the method, by using a seed cellar sand storage and breeding technology, the
germination percentage is high; and by adopting indoor temperature-changed germination hastening, the rate of
seedling emergence is high.
