Description

A kind of optimal water salt threshold value breeding method of Reed rhizome budding
Technical field
The present invention relates to a kind of optimal water salt threshold value breeding method of Reed rhizome budding.
Background technology
Reed (Phragmites australis) is perennial rhizome type dogstail, cosmopolitan, in fresh water and salt water Marsh can be distributed, and be one of the main marsh type in China.Reed has two kinds of breeding sides of seminal propagation and division propagation Formula, but it is typical clonal line, and natural population relies primarily on supplement renewal of nourishing and generating.Reed crawl root-like stock hair Reach, scope length in root area is deep also up to more than 1m below topsoil up to several meters.
Reed has extensive economic value:1st, the crude protein content of vegetative growth phase occupy first-class in dogstail, is one The excellent feed of kind;2nd, the reed stalk in maturity period is hard, and quality is fine and smooth, fiber content height (40%~60%), is China's weight The paper making raw material and handicraft raw material wanted;3rd, root is huger, can absorb heavy metal and other pollutants, has efficient Water quality purification function;4th, plav is fish, shrimp, shellfish, crab settlement, is the place that various aquatic birds, birds inhabit, has and inhabit The function on ground and abundant bio-diversity;5th, plav vegetation coverage, biomass is big, have swamp protection, carbon fixing and Improve the important Ecology Actions such as salt-soda soil.
Very serious, relevant departments' just actively input substantial contribution recovery degeneration however, China's reed wetland is degenerated at present Reed wetland, but relevant recovering technology is still very limited;Existing Propagation of Rhizomes method mostly enters from the angle of envirment factor Hand improves germination rate, ignores the influence of biotic factor in itself.Therefore, consider quickly to breed reed in itself with full from rhizome Sufficient industrial and agricultural production and environmental protection need, and have important practice significance and application value.
The content of the invention
The dependency number of rhizome budding can not intuitively be reflected from envirment factor the present invention is to solve existing Propagation of Rhizomes method According to, it is impossible to the problem of providing the water salt scope that can plant reed with reconstruction for the recovery of field degeneration sabkha, and a kind of reed is provided The optimal water salt threshold value breeding method of reed root stem budding.
A kind of optimal water salt threshold value breeding method of Reed rhizome budding of the present invention is to carry out according to the following steps:
First, field Reed rhizome gathers:In the plant roots and stems budding time of annual mid or late April, inland or beach are chosen The uniform sampling point of growth of seedling in plav, by way of small patch takes rhizome, take to horizontal rhizome, it is optimal to dig It is 20~30cm to take depth, after taking rhizome, is fitted into black plastic bag, avoids sunlight, and spray moisture;
2nd, Reed rhizome is handled:The Reed rhizome taken is rinsed, cuts aerial part, retains underground rhizome As material is cultivated, health, a diameter of 4~7mm rhizome is therefrom chosen, the segment of 20cm length is cut into, ensures each segment At least 2 nodes, obtain Reed rhizome to be cultivated;
3rd, cultivate and rhizome Budding process detects:Will Reed rhizome be cultivated temperature be 22 DEG C~28 DEG C under conditions of It is placed in plastic tub and is cultivated by matrix of quartz sand, stromal thickness 5cm, salt solution is poured into plastic tub to no mistake stone Sand surface, rhizome Budding process is monitored:Supplement water pours 500mL salt solution in every 2 weeks to ensure constant level daily, When plumule elongation 2mm is to germinate, i.e. the optimal water salt threshold value of completion Reed rhizome budding is cultivated;The mass concentration of the salt solution is equal For 5 ‰.
The beneficial effects of the invention are as follows:
This method carries out Reed rhizome budding using the salinity of the 0cm depth of waters 5 ‰ and cultivated, the results showed that, match somebody with somebody with other water salt Than compared to the inventive method makes the budding time at least shorten 3 days, and bud ratio, survival rate and relative growth rate difference are at least Improve 26%, 19%, 0.06cm/d.The efficiency that this method will improve degeneration salt marsh restoration with rebuild, and it is cost-effective.
