Abstract: A film sheet for area-focusing of sunlight and a greenhouse provided with the same are provided. A film sheet includes i) a film having a rectangular shape, and ii) a plurality of prism assemblies formed on one surface of the film to extend in one direction. At least one prism assembly of the plurality of prism assemblies includes i) at least one first prism unit including a plurality of first prisms with slanted angles that are substantially the same as each other, and ii) at least one second prism unit neighboring the first prism unit and including a plurality of second prisms with slanted angles that are substantially the same as each other. The width of the first prism unit is substantially the same as the width of the second prism unit and a slanted angle of one first prism among the plurality of first prisms is different from a slanted angle of one second prism among the plurality of second prisms, and light entering the prism assembly is configured to be area-focused.

Abstract: A method is provided which can efficiently remove conidia and microbe or the like of a phytopathogen from air and does not cause generation of ozone originated from discharge or so, thereby preventing occurrence of a plant disease without damaging a plant. There are also provided a flying organism removing apparatus and a plant protecting apparatus which can adequately capture flyable organisms, such as spores of a phytopathogen and/or small vermin, by applying an electrostatic field to the flyable organisms. An electrostatic field generated by dielectric polarization is applied to flyable organisms.

Abstract: A process for photomorphogenically enhancing plants is presented wherein a natural or artificial light source emits light through a transmittive material. The material is optionally borosilicate glass with a steep edge situation at or near 280 nm so as to selectively filter out light in the UVC or low UVB regions. The glass allows high transmissibility such that as much as 98% of all light at or above the edge situation passes thorough the material. The percent transmission and edge situation may be defined by glass thickness or by combining multiple types of glass. The light is then contacted with a plant whereby a photomorphogenic response is elicited.

Abstract: The apparatus comprises a compositing bin (10), which may be constructed from modular elements (13), provided with a perforated or slatted floor (14) of a bedding frame (11) incorporated over the bin (10). The frame (11) is covered by a pyramidal roof structure (12), of translucent plastics panels, these can be connected into pairs by flexible tapes (18), the other edges being connected by tapes (19) incorporating sliding clasp fasteners (20). The bottom edges of the panels may be provided on their inner sides with channels (17) to trap condensation, and the edges of the panels may be reinforced by rods or dowels (22) in tunnel seams in the tapes (18, 19).

Abstract: A cone shaped, multi-use garden accessory, consisting of a single unit. The cone body is open at each end. The base, or larger end, is formed by a rounded rim. The neck, or smaller end, has a tubular extension with prongs affixed. Stiffeners are arrayed within the cone and extend through the tubular neck and along the prongs. The entire structure is composed of translucent, semi-rigid or rigid material.

Abstract: A surface-covering protective structure. A thermal insulation layer has a basic wall thickness, fastening elements and a support arrangement integral with and projecting from the basic wall thickness of the thermal insulation layer. The support arrangement includes a plurality of supporting feet each comprising a supporting surface being operable to engage a protected surface that the protective structure is arranged on. The support arrangement is operable to physically separate the basic wall thickness of the thermal insulation layer from the protected surface. The fastening elements are operable to couple adjacent protective structures together. The protective structure, including the basic insulation layer, the fastening elements, and the support arrangement, includes thermally insulating plastic material operable to thermally insulate the protected surface.

Abstract: A hanging planter includes a bowl-like lower portion and a ring-like upper portion, with the upper portion nesting within the rim of the lower portion to provide a plant holding assembly. The upper edge of the lower portion and lower edge of the upper portion are crenelated, with the mating edges defining a series of plant growth openings therethrough when the two components are assembled. The crenelations are preferably of variable depths in each section, to define at least two different levels of plant growth openings through the sides of the assembly, with the upper edge of the upper portion defining a third plant growth opening for the device. Plants are selected according to their growth habits, with trailing plants being placed low in the planter, long flowering plants being placed at an intermediate level, and more upright plants being placed atop the others. The result is an essentially unbroken array of plant life covering the present planter, after the plants have grown out.
