Description
Technical field
The invention belongs to biotechnologies, are more particularly to a kind of rhizome section quick propagation method of water pepper, it is applicable in
The demand to a large amount of high-quality water pepper seedlings is built in wetland recovery, artificial swamp and light industry raw material site.
Background technology
Water pepper（Polygonum hydropiper L.）, alias polygonum flaccidum, flaccid knotweed herb etc., have in most of china area
Distribution, the wetlands habitats such as raw river shoal, ditch side, lakeside.Water pepper stem is upright, multi-branched, 40-70 centimetres high, and raceme is in fringe
Shape, achene is avette, wraps in the perianth harbored, the month at florescence 7-8.《Chinese Plants will》And in chorogophic description, water pepper
For annual herb, but in conversation in Dongting Lake area, due to adapting to the wetland habitat of Seasonal flooding for a long time, water pepper generates very flourishing
Underground root-like stock, the aerial part of water pepper（Stem, leaf）It is withered in winter, next year green sprouting shape overwintering with underground root-like stock
Into ground plant division.
Water pepper adapts to water and rises the alternate environment fallen, has the characteristic of " giving birth in land and water two ", be many large-size lake wetlands such as
One of dominant plant coenotype of Dongting Lake and Poyang Lake.Water pepper has very flourishing root-like stock, there is radicula and children at section
Bud, every square metre of bud number is up to 484 ± 78（Average ± standard error）.Water pepper is a kind of important group's class of lake and marshland
Type has and provides habitat, purifies water, the multiple functions such as biometric safeguard diversity.In addition, water pepper herb can be used as medicine, it is
A kind of traditional Chinese medicine, extract are also used as agrochemical.Some researches show that using water pepper, group establishes Manual moist
Ground has very strong clean-up effect to the waste water of the heavy metal pollutions such as manganese.As the middle and lower reach of Yangtze River restores farmland to lakes, artificial swamp etc.
A large amount of implementations of engineering, it is more and more urgent to the seedling demand of water pepper, and current technology will be difficult to meet growing city
Field demand.Therefore, it is inevitable demand to invent a kind of method that can quickly provide a large amount of high-quality water pepper seedlings.
Through Chinese patent net and correlative theses retrieved web, find there is presently no the report of water pepper quick breeding technology,
Report more only about water pepper cultivation technique, as Ma Yumei " water pepper high-yield cultivation technique " [Crop Diseases in Yunnan, 2008
（6）：14] it mentions and is broadcast live nursery with seed；Pan Niansong etc. " production Dong Jiu with polygonum flaccidum plant Key Technology " [In Cure clinical research, 2015,7 (30)：134-135] mention the technologies such as sowing, the final singling of water pepper.But water pepper seed is small, germination percentage
The low and seedling period is long, it is difficult to provide a large amount of engineering seedling in a short time.
Invention content
It is easy to implement the method the purpose of the invention is to provide a kind of rhizome section quick propagation method of water pepper, operation letter
Just, it is short to expand numerous period for the method for the present invention, and germination rate is up to 90%, and transplanting survival rate is up to 95%.It can quickly be provided greatly by the method
High-quality water pepper seedling is measured, and at low cost so that a large amount of high-quality water pepper seedling can be obtained in a short time, it is extensive to meet muskeg
The needs that multiple, artificial swamp and light industry raw material site are built.
In order to realize above-mentioned purpose, the present invention uses following technical measures：
A kind of rhizome section quick propagation method of water pepper, step are：
（1）It draws materials in field：The water pepper group that conversation in Dongting Lake area grows fine is chosen, after aerial part is gathered in, takes ground
The rhizome of lower 0.1-10cm soil layers.Get colors pink and healthy and strong annual rhizome.The rhizome of water pepper easily snaps off, sampling
Rhizome is made to keep complete as possible during with dress sample.
（2）Select rhizome section：The rhizome that field is fetched tap water is rinsed 2-3 times, washes off soil, and protect rhizome
Hold moisture state.Long rhizome is cut into the rhizome section that length is 3-5 cm with scissors, and ensures each rhizome section there are one complete
Whole internode and an axillary bud stay 1-2 cm rhizomes on the outside of axillary bud.
（3）Impregnate rooting powder solution：It is small that the rhizome section sheared is put into immersion 1.5-2.5 in the rooting powder solution of 2 g/L
When, it takes out spare.
The root-inducing powder main component is 90% methyl α-naphthyl acetate original powder.
The rooting powder solution is that 2g root-inducing powders are dissolved in 1L tap water to get to the rooting powder solution of 2 g/L.
（4）Prepare culture substrate：By river sand（Commonly）2 mm sieves are crossed, the bulky grains objects such as gravel pebbles are removed, then by river sand
And peat soil（Commonly）By volume 1:1 be uniformly mixed be configured to culture substrate, it is spare.
The culture substrate refers to provide the solid dielectric of machinery support and nutrition supply for plant for soil；
The solid dielectric is the arbitrary proportion mixture of middle finger river sand and peat soil of the present invention.
（5）Seedbed preparation：Seedbed should select be not easy ponding, and without trees or the location of building shade.It will culture
Matrix is layered on seedbed, thickness 9-11cm.
（6）Sowing：The rhizome section chosen is placed horizontally in seed furrow（Depth 0.8-1.1 cm）, it is first between rhizome section
Tail is connected.Then above-mentioned steps are used（4）Culture substrate covers, and thickness is in 0.5-1.0 cm.
（7）Culture：A water is poured daily, and irrigation amount is advisable so that culture substrate to be kept to moisten without ponding.It is best during watering
Sprinkling or spraying are taken, flow should not be big, causes rhizome section exposed in order to avoid washing away matrix.Sprout starts to sprout after 5 days, 2 weeks
Interior germination rate is up to more than 90%.2 weeks seedling heights can reach 10 more than cm after emergence.
（8）Transplanting：Seedling reaches 13 centimeters or more after 3 weeks, 8-10 piece leaves, and new root is grown on rhizome, by plant from matrix
In dig out, be transplanted in soil.
The present invention establishes the technical system of a fast-propagation water pepper, compared with prior art, the present invention with following
Advantage and effect：
（1）Material source is simple, and the underground rhizome of water pepper is flourishing, every square metre of bud number average out to 484；
（2）Period is short, is only needed 20 days or so to transplanting from bud is broadcast；
（3）Rhizome section germination rate is high, reaches 90%, rooting rate is up to 100%；
（4）Emergence is neat, and transplanting survival rate is high, is 95%；
（5）It is technically simple, it is easy to grasp, and at low cost, suitable for large-scale production seedling；
（6）Material therefor is taken at conversation in Dongting Lake area in the present invention, can be overwintering by underground rhizome, can be widely used for river
Shore, recovery of lakeside areas and light industry raw material site are built.
