Abstract
The invention relates to a cattail seedling selecting and conservation method for wetland restoration. The cattail seedling selecting and conservation method for wetland restoration aims at solving the technical problem that an existing cattail seedling selecting and conservation method is long in growth period and high in cultivation cost and selected seedlings have poor capacity of adapting to a new environment and easily rot, die and the like. The cattail seedling selecting and conservation method for wetland restoration comprises the steps of 1 cattail seedling base selection; 2 seedling collection, namely a discontinuous and blocky excavation mode is adopted to excavate cattail rhizomes serving as breeding parents in a seedling base and obtain collected cattail seedlings; 3 seedling root division and conservation, namely the collected cattail seedlings are separately arranged in a single-plant mode, each seedling is required to be provided with a section of rhizome or a fibrous root, the roots of the collected cattail seedlings are immersed into water before transplant, and accordingly cattail seedling selecting and conservation are completed. The cattail seedling selecting and conservation method enables the cattail survival rate to be higher than 85% and is applied to the field of cattail wetland restoration.
Description
Technical field
The seedling that the present invention relates to for wetland recovery is chosen and nursing method.
Background technology
Cattail is a kind of perennial aquatic herbaceous plant, is distributed in the shallow waters such as loke shore, marshland, pond, irrigation canals and ditches more, and general is that clump tufted grows in flakes.Cattail another name is also called cattail pollen, the stem or leaf of cattail, because its spike is candle shape, therefore is again water candle.Cattail plant height generally between 1.4-2.5m, have up to more than 3m, its blade is long and narrow linear, two column alternates, long 40-70cm, what have reaches 1m, wide 2-3cm, and color and luster is dark green, light weight and soft, mesophyll tissue is the slot lattice of hollow, has typical hygrophyte structure.The flower of cattail becomes yellow green, and Hua Sui is elongated, cylindric, male and female inflorescence compact siro spinning technology, and fruit ear ceraceous candle shape, reddish brown brown, seed is tiny, hairiness, can be scattered with the wind.The underground rhizome of cattail is creamy white more, and stem is grown and how horizontal sprawl growth, and the raw many fibrous roots in place of stipes portion, normal and other warped roots cooperatively grow.
Cattail is a kind of typical wetland plant, and the Habitat Types be made up of the cauline leaf of its acrial part is important breeding and the habitat of umbrette and many swallow duck class aquatic birds.The stem of cattail, leaf, flower are all used as medicine, and tender shoots claims common cattail, edible.Leaf is widely used for the practical art product such as processing and opanken, fan, pad, basket; The green fringe of cattail leaf is strange, and being often used to intersperse pond, gardens, lakeside, constructing water scenery, is the important species carrying out wetland recovery.
Cattail has seminal propagation and vegetative propagation two kinds of modess of reproduction.Cattail seed demand could be sprouted under humidity and suitable temperature condition.Under nature the sprouting of cattail seed and survival rate all very low, the wetland recovery therefore utilizing seminal propagation to carry out is also rare.It is a kind of important vegetative manner that rhizome is transplanted, and is widely adopted at present, but the seedling that the seedling that this method gathers is cultivated mainly with artificial plantation is main.Because artificial culture seedling needs the certain growth cycle, need to pay certain cultivation expense, and seedling limited amount, particularly at the plantation initial stage, this kind of seedling is not strong to the adaptive capacity of newborn environment, the phenomenons such as easy appearance is rotten, dead, therefore also just greatly limit its large area in the wild under condition and recover.
Summary of the invention
The present invention will solve existing cattail seedling to choose the growth cycle existed with nursing method long, cultivate costly, and the seedling chosen is not strong to the adaptive capacity of newborn environment, the technical problem of the phenomenons such as easy appearance is rotted, dead, thus provide a kind of cattail seedling for wetland recovery and choose and nursing method.
A kind of cattail seedling for wetland recovery of the present invention is chosen and carries out according to the following steps with nursing method:
One, cattail seedling base is chosen: choosing growth cycle under natural environmental condition is that the cattail group of 3-4 is as seedling base;
Two, seedling gathers: take excavation mode that is discontinuous, strip and block, the cattail rhizome in seedling base is excavated as breeding parent, the patch width of each strip and block is no more than 2 meters, then stem or leaf of cattail seedling is grubbed out out, with water, the earth be bonded in rhizome is washed off, expose rhizome, the stem or leaf of cattail seedling gathered;
Three, seedling divides root and child care: the stem or leaf of cattail seedling gathered step 2 obtained is separated with individual plant form, every strain seedling need with one section of rhizome or fibrous root, before planting, the stem or leaf of cattail seedling root gathered is immersed in water, namely completes choosing and child care of cattail seedling.
The present invention includes following beneficial effect:
1, the inventive method is aimed at and needs a large amount of seedling in large area degraded wetland recovery process and a kind of seedling of setting up gathers and child care technology, adopts this method that cattail survival rate can be made to more than 85%.
2, there is the wild cattail group of 3-4 annual life circle, be in the mature stage in life cycle, there is the rhizome that place is sturdy, compared with the seedling of artificial propagation, there is higher parent's property and stronger adaptability, utilize this seedling to transplant, slow seedling process can be completed fast, realize fast recovering target.
3, gather the wild cattail seedling grown under natural situation, seedling culture and the administrative expenses of paying early stage can be avoided, greatly can reduce Resuming agent, there is higher economy and generalization.
4, the present invention is adopted to take the excavation mode of discontinuous strip and block to gather seedling, be conducive to the expansion of the old root of original group, also provide growing space for newborn root system, can Community Degradation be prevented, simultaneously originally also can be effectively restored in 1 year by the exposed region excavated.
5, the stem or leaf of cattail seedling root gathered is immersed in water and can prevents seedling from dewatering by the present invention, improves survival rate; If the stem or leaf of cattail seedling long-distance transportation gathered, then put into the bubble chamber filling a small amount of moisture by seedling, be beneficial to the water conservation moisturizing of seedling, do not flood whole strain simultaneously, to carry out photosynthesis and respiration.
