Embodiment 1

[0020] A method for raising seedlings of Rhizoma Polygonatum Rhizome, which is characterized in that providing a method for raising seedlings of Rhizoma Polygonatum Rhizome, comprising excavating seedling ditch, placing anti-seepage geotextile, sterilizing rhizomes, pulling and covering shade nets, and managing seedling watering . The steps are: (1) Land selection: select a hillside with sandy soil not exceeding 10-15°C, and excavate a deep trench with a depth of 40cm and a width of 60cm from top to bottom every 50cm in a horizontal order; (2) Place the anti-seepage geotextile: fold the anti-seepage geotextile into grooves with an interval of 15 cm at the bottom of the ditch and place it on the bottom of the ditch, then backfill the soil to a distance of 10 cm from the ground, and mix the soil with farmyard manure on the pile to make it 10 cm higher than the land. (3) Sprout cutting and sterilization treatment: select rhizome blocks with 2 to 3 sprouts above 10cm, cut them int...

Abstract

The invention relates to a method for culturing seedlings of polygonatum kingianum rhizome. The method is characterized by comprising the following steps of selecting hilly land with the temperature of not more than 10-15 DEG C, excavating a channel with the depth of 40-45cm and the width of 60cm at every 50cm from top to bottom transversely, placing anti-seepage geotechnical cloth which is folded to be provided with a groove of 15cm on the bottom of each channel, and placing soil mixed with farmyard manure on the upper layer of backfilled earth to form seedling culture land; selecting rhizome blocks of more than 5cm and with 2-3 buds, cutting the rhizome blocks with a disinfected and sterilized cutter, adhering the incisions of the cut blocks by utilizing a self-made biologic membrane, and planting the cut blocks in the seedling culture land after the cut blocks do not drop water for 10-20 minutes, wherein the line spacing of seedlings is 15-20cm; covering a sunshade net over the seedling culture land with the planted rhizome seedlings at the height of 1.5-2m; and watering once to twice at every three days, culturing the seedlings for 35-45 days, and transplanting the seedlings after the seedlings grow to 20cm. The method for culturing the seedlings of the polygonatum kingianum rhizome, disclosed by the invention, has the advantages of easiness in material obtaining and high yield, and is suitable for culturing the seedlings in water-shortage land.
