Connect and compose the palisade floating bed at interval with many half sheet mao bamboons, the bottom of floating bed is with rigid plastics net back cover, plantation aquatic flowers plant Canna generalis Bailey in the slit between the mao bamboon bar, single variety or the several kind in power flower, yellow flag or the cyperus alternifolius again, look stand density and gather in plant shoot at any time, it is transferred to other local pooling of resources processing, finally gather in winter, toothing is kept a full stand of seedings, punch on the half sheet mao bamboon, plantation Chinese celery or Nasturtium officinale in the hole, the harvesting while growing, finally gather in summer, and toothing is kept a full stand of seedings.

Usually, the spacing between the mao bamboon bar is 10-15cm, the aperture 0.3-0.5cm on the mao bamboon, pitch of holes 1-2cm.The every strain of the flower plant of plantation is 25-35cm at interval.

The present invention is become a useful person mao bamboon for well to adopt 4-6, and its aging rotten speed is slow, can prolong the working life of floating bed carrier.

Mao bamboon has good physics characteristic, and the bamboo wood shrinkage is little, the isolating property of tool height, elasticity and toughness, and rift grain tension, ultimate compression strength are big; Its MOR, Young's modulus, intensity are 2 times of general timber; Bamboo wood density is 0.789g/cm3, and forward the anti drawing strongly degree reaches 201.7Mpa, ultimate compression strength 74.2Mpa; Internode hollow can float on waterbornely naturally, and weight capacity is strong.

Therefore, mao bamboon is as the floating bed solid support material, and it is low, corrosion-resistant to have a cost, and supporting capacity is strong, and is high with the warm degree of environment, is difficult for causing advantages such as visual pollution; The floating bed carrier that utilizes mao bamboon to do, its water permeability is good, is beneficial to plant-growth.

Beneficial effect of the present invention is:

The present invention is the floating bed carrier with the mao bamboon, by interplanting the plant of two kinds of Various Seasonal, under the situation of not changing carrier, can realize that the anniversary of aquatic plant purification system is moved continuously; The root system of plant by prosperity absorbs the nitrogen and phosphorous nutrient in the eutrophication water in a large number, and upwards is transported to plant shoot; Regularly or when treating that the fraction of coverage of plant on the water surface is overstocked, gather in its top, and with the overground part material transfer of harvesting to the processing of elsewhere pooling of resources, can realize the decontamination effect improving of eutrophication water; Wherein greengrocery such as Chinese celery, Nasturtium officinale plant can be gathered in repeatedly in vegetative period, by can be as good winter-spring season vegetables after the food inspection; And Canna generalis Bailey, power flower, yellow flag are flowers class plant again, are administering body eutrophication, when increasing water quality, can improve water landscape, beautify the environment, and can make green manure.The method of improvement eutrophication water of the present invention not only can be taken away nutritive salt such as a large amount of nitrogen, phosphorus from eutrophication water, purify water; Secrete allelochemical simultaneously, can suppress algae reproduction.This method is to making up the healthy water ecotope, improve water landscape, the actively favourable effect of increasing water quality, and less investment, easy maintenance, effect is lasting, working life is long, and is high with the warm degree of environment, non-secondary pollution, the resource utilization of cash crop behind the repairing and treating can be brought certain economic benefits, has very big application potential.
