The application is a kind of sea embankment slope ecological reconstruction structure and its construction maintenance method, including embankment body, transverse concrete retaining wall with ladder distribution is arranged in the embankment body, combined with longitudinal concrete retaining wall, so that the embankment body forms a plurality of planting pits, the planting pit can be quickly filled with organic fertilizer soil by mixing feeding equipment, to efficiently realize the purpose of plant planting, and after filling, the whole embankment body slope is ladder type, and under the action of the retaining wall, it can effectively prevent water and soil loss and improve the survival rate of vegetation, the planting pit below the high tide line of the embankment body is closer to the sea, and it plants strong salt-tolerant plants such as sea spirogyra, bitter tree, alkali grass and thick vine, while the upper part of the embankment body is far from the sea, and the planting pit plants drought-resistant shrubs and grass (vine) plants such as single leaf vine, kikuyu grass, oleander, grey lily and narrow leaf agave, to realize the sustainable development of the sea embankment and improve the ecological function of the sea embankment.

The present invention relates to the field of remediation of heavy metal contaminated soil, and discloses a method and application for phytoremediation of heavy metal contaminated soil by combined planting of plants. The present invention selects shrubs and herbaceous plants with relatively fast growth rates and that can be repeatedly harvested, and adopts a plant configuration mode of "shrub + herbaceous". By utilizing the characteristics of rapid growth of shrubs and herbaceous plants, the problem of slow existing phytoremediation can be solved. According to the different root depths of shrubs and herbaceous plants, the remediation of heavy metal contaminated soil in different soil layers can be taken into account. For example, the characteristics of deep roots of shrubs such as Schefflera odorata var. variegata and Nerium oleander can be used to remediate heavy metal contaminated soil in deeper soil layers, and the characteristics of shallow roots of herbaceous plants such as Pennisetum alopecuroides and Ruellia brittoniana can be used to remediate surface contaminated soil; after planting, by slightly pruning the shrubs and appropriately pruning the herbaceous plants, a relatively good landscape effect can be formed; by regularly harvesting fast-growing shrubs and herbaceous plants such as Schefflera odorata var. variegata, Pennisetum alopecuroides and Ruellia brittoniana, the effect of repeated adsorption can be achieved.

The application discloses application of an acid hydrolysate of an oleander ethanol extract in preparation of a marine slow-release antifouling agent. The acid hydrolysate is prepared by taking tender stems and tender leaves of the oleander as raw materials, extracting the raw materials by using an ethanol solution, and then performing acid hydrolysis. The acid hydrolysate has a significant inhibiting effect on attachment of marine macrofouling organisms, and shows high antifouling activity. The release rate of the acid hydrolysate in antifouling paint is much smaller than that of the oleander ethanol extract before hydrolysis, so that the acid hydrolysate can be used to prepare the marine slow-release antifouling agent.
