A vertically-integrated greenhouse for growing plants in suspended trays. The design is particularly well-suited for installation in a double-skin façade of a building, or in an interior atrium, lobby, or similar structure.

The invention discloses a rock slope ecological protection afforestation substrate. The substrate is prepared by evenly mixing a mixture of mixed and fermented straw, cattle manure, edible fungus refuse (the waste after the edible fungus production), sludge and organic matter fibers, compound fertilizer, a soil moisture holding agent, a binding agent, attapulgite powder and a pH regulator. The rock slope ecological protection afforestation substrate is used to carry out the spray seeding and greening on the exposed rock slope, the discarded mine and the mountain gap, and can maximally restore the vegetation ecology in a shorter period, thereby reaching the aims of afforestation and slope protection. The substrate can supply a reasonable physical structure and nutrient contents needed by the growth of the vegetation, and ensure the sufficient cohesion force between the substrate mixture on the slope surface and the rock slope so as to ensure that the vegetation on the slope surface can take root and grow well on the rock slope. The substrate can ensure the stability of the substrate mixture on the slope surface so as to resist the rain erosion. The substrate can rapidly seal the slope surface and prevent the slope surface from flaking off due to efflorescence together with the vegetation.

The cultivation of terrestrial plants in brackish water or seawater is carried out with this invention. A light-weight, floating growth medium package (FGMP) or, alternatively, a sheet of suitable material is used to support the growth of terrestrial plants floating on water bodies of various salinity, including 100% seawater in marine environments. The FGMP units can be linked together and confined in a floating, rigid or flexible framework to form a floating seawater cultivation platform (FSCP). Using the method, plants were able to grow and thrive on the FSCP floating on 100% seawater in a sustainable manner. Halophytic akulikuli (Sesuvium portulacastrum L.) can regenerate its shoot and root in seawater. Thus, the discovery will enable us to practice marine agriculture, or agriculture on the sea. The FSCP can be used for wide range of purposes, from environmental protection to landscaping to crop production.
