Abstract

Terrestrial stems of miscanthus sinensis are cut off before winter and burnt as waste and firewood. The invention provides a method for germinating and storing stems of miscanthus sinensis. The method comprises the following steps of: (1) cutting off a stem of miscanthus sinensis in later October when 3 to 4 leaves at the stem base turn yellow, and removing the leaves and keeping four stem segments close the stem base; (2) treating the stem segments of the miscanthus sinensis with hormone; (3) storing the stem segments in sand; and (4) after storage for a month, getting the stem out every 20 days and sticking the stem by a fractional cuttage method at room temperature, with the rate of emergency reaching 80 percent between November and early Match and the maximum of 96 percent between January and February. The method can breed indoor miscanthus sinensis at a high rate in slack farming season, breed 3 to 4 strains of new seedlings by use of one stem, and grow cuttage seedlings with strong roots, and hence a mature technique for commercially breading miscanthus sinensis.

Description

Miscanthus sinensis stalk storing and germination accelerating method
Technical field
The present invention relates to spire awns (Miscanthus sinensis ' Gracillimus ') stem stalk storing and germination accelerating method.Comprise that specifically ripe stem stalk HORMONE TREATMENT of spire awns and low temperature storage expedite the emergence of two steps of axillalry bud, by this propagation technique, solve the lower problem of awns platymiscium reproductive efficiency, utilize the stem stalk of cutting before the winter, cuttage farm slack season in the winter time realizes the batch process of spire seedling in Grain in Ear.Belong to agricultural biological technical field.
Background technology
The spire awns belongs to herbaceos perennial for the grass family awns, plant height 1.5-2m, and the stem stalk is intensive grows thickly, and the strain clump is graceful circle, leaf is upright, very thin, and it is arc that the top is, and give birth on the panicle top, the florescence 9-10 month, pattern fades to redness by initial pink, transfers silvery white autumn to.Under natural environment, the spire awns is by root-like stock breeding, and annual 4-5 month is from the root-like stock director plant that makes new advances, 8-9 month plant height reaches 1 meter, extracts inflorescence October out, the withered (Wu Juying of acrial part in December, view and admire grass and the application in garden landscape thereof, China Forest publishing house, 2008).Leaf is elongated, becomes pale brown look autumn.Spire awns happiness light, cold-resistant, drought-enduring, waterlogging, strong stress resistance has a extensive future in garden landscape, roadside greening.
The spire awns is mainly used division propagation at present, and speed is very slow, can not satisfy market demand.Congener cottage propagation technology is not appeared in the newspapers both at home and abroad.
Summary of the invention
The objective of the invention is to set up Miscanthus sinensis stalk storing and germination accelerating method.
Content of the present invention comprised with the hormone concentration of the ripe stem stalk processing of spire awns and temperature, the time of stem stalk storage.
The present invention sets up Miscanthus sinensis stalk storing and germination accelerating method, November to next year 3 monthly can be in the greenhouse cuttage Cheng Miao, every stem stalk can breed 3-4 strain new talent, cuttage seeding root system stalwartness is to be suitable for the commercial vernalization technology that expands excessively detailed leaf awns.
(1) the ripe stem stalk of spire awns HORMONE TREATMENT is that following method is selected one: A.6-benzylamino adenine 6-BA 10-20mg/L soaks 12-24h; B 6-benzylamino adenine 6-BA 100-500mg/L soaks 1-3h; C. gibberellin GA 310-20mg/L soaks 12-24h; Gibberellin GA 3100-500mg/L soaks 1-3h.
(2) temperature, the time of the ripe stem stalk storage of spire awns are: reserve temperature 4-10 ℃, storage time is 1-5 month.
The scheme of technical solution problem of the present invention divides following two steps to finish:
(1) HORMONE TREATMENT: from base portion clip spire awns stem stalk, be cut into the stem section of 3-4 joint of every section band, carry out HORMONE TREATMENT.
(2) storing and germination accelerating: after the HORMONE TREATMENT, the stem section is preserved in wet sand, places 4-10 ℃ of refrigerating box, after lateral bud begins to expand in the time of 1 month, takes out stem segment cuttage Cheng Miao.
Embodiment:
Further illustrate the present invention in the following embodiments, this does not limit the scope of the invention.
Embodiment 1
On October 20th, 2,007 1000 sections of clip spire awns stem stalks in base, Beijing Grass Industry ﹠. Environment Research Development Center Xiao Tang mountain, 3-4 stipes of every section band, remove blade after, the stem stalk is with 6-benzylamino adenine 6-BA 20mg/L immersion 24h.Be housed in 25cm * 40cm * 15cm pigment basket after taking out the stem stalk, the stem section is tiled in the wet sand, and every basket of shop 3 is thick, is placed in 4 ℃ of refrigerating boxes with the preservative film sealing and preserves.
After 30 days, spire awns stem section has 53% lateral bud to begin to expand, and takes out 100 sections, divides 3 groups, and every group all has 100 lateral buds, cuttage in the greenhouse, and planting percent reaches 73%.After 50 days, spire awns stem section has 68% lateral bud to expand, and the cuttage planting percent reaches 82%.After 70 days, spire awns stem section has 78.2% lateral bud to expand, and the cuttage planting percent reaches 95%.After 90 days, spire awns stem section has 79.1% lateral bud to expand, and the cuttage planting percent is 90%.After 110 days, spire awns stem section 80% lateral bud expands, and the cuttage planting percent is 82%.After 130 days, the cuttage planting percent is 69%.After 130 days, the cuttage planting percent is 62%.
