A polytunnel structure is described having a plurality of cover support members supported upon respective pairs of legs, a cover member supported by the cover support members, an edge of the cover member being secured to a rotatable beam, and an anchor rope, strap or the like extending over the cover member to anchor the cover member in position, wherein the cover support members are each shaped to define a step between a first section and a second section, wherein when the rotatable beam is supported upon the second section, the anchor rope, strap or the like provides a reduced resistance to movement thereof.

A device for growing plants above a selected surface includes a bottom member disposed upon a selected surface; a top member disposed upon and secured to said bottom member via two longitudinal securing seams, whereby, said top member includes two outer longitudinal flap portions and a longitudinal center portion, which ultimately receives a growing material in which plants and/or seeds are disposed. The longitudinal flap portions are ultimately folded above the growing material whereby longitudinal edge portions of the flap portions are separated a predetermined distance for allowing water and light to engage the growing material. Pipe members are removably secured to longitudinal edge portions of each longitudinal side of the bottom member, thereby enabling the manual lifting and transport of the device for disposal upon a selected surface.

A modified device for growing plants upon an undulating surface includes the above device with multiple apertures disposed proximate to a selected inner portion of a folded lower flap portion of the top member; and at least one water retaining member disposed between the folded lower flap portion of the top member and a lower elevation side of the bottom member.

The present invention concerns an elongated sheet (1) for covering agricultural cultivated plants (2), with a basic film (3) of plastic, wherein a ventilation area (5) extending in the longitudinal sheet direction (L) and having a plurality of ventilation openings (6) is provided in the central area (4) of the basic film (3), wherein a cover film (9) of plastic extending in the longitudinal sheet direction (L) of the basic film (3) is applied to the ventilation area (5), forming free spaces (11) for air exchange, and is firmly welded to the basic film (3) over a plurality of connection areas (10) following one another in the longitudinal sheet direction (L), and
wherein the connection area (10) is designed to be inclined, at least in some areas, with respect to a weld start point (12) and a weld end point (13) with respect to the cross direction (Q) extending orthogonally to the longitudinal sheet direction (L).

A shield for protecting a plant having; a stem having an upper end and a lower end; a first plurality of sticks having a proximal end and a distal end; and a pad associated with the upper end of the stem, the pad having a second plurality of holes distributed all around the pad and oriented at various angles in relation to a horizontal plane, the holes being configured for removably receiving the proximal ends of the entire first plurality of sticks or a portion thereof and securing the same therein through friction-based insertion; the second plurality of holes distribution and orientation allowing the formation of a support structure for a protective cover in which the entire first plurality of sticks or a portion thereof extends in a circular arrangement above the plant at an angle conforming to the shape or size of the plant.

The invention discloses environment-controlling fibers, method manufacturing the same and fabrics using the same, which adopts polyolefin material, optoelectronic material, thermoelectric material, piezoelectric material and catalyst material, to make fibers and fabric by melting, mixing, drawing and weaving. The fabrics are used in all kinds of environmental control products or for organic agriculture. To use green energy such as solar light energy, solar thermal energy, wind energy, hydro energy, geothermal energy and other renewable energy to stimulate the function of the special material within the fibers, so that the fabrics can remove pollutants in the environment and produce self-purification function to achieve the purpose of improving the environmental conditions or promote plant growth.

An expandable, portable, and semi-permanent garden planter box for the cultivation of plant life with an enclosable canopy for allowing limited control of the immediate atmospheric environment. The garden planter box is assembled from multiple component blocks capable of longitudinal and vertical integration providing the structural integrity of a solid structure and the adaptability and portability of structure composed of multiple interchangeable component parts capable of relatively easy assembly and disassembly without special tools or heavy equipment.
