摘要:
The embodied invention is a framework and expanding cover for a crop row that is designed to provide an enhanced crop growing environment. The framework design utilizes a top and bottom cover with affordable materials that are suitable for large scale production. The design also includes an irrigation, fertilizer, and CO2 injection system that provide an enhanced environment for plants to grow. The entire system is reducible to a small package to better facilitate use in a broad variety of environmental and personal situations.

Embodiments relate to a method for manufacturing a heat-shielding film in which a heat-shielding material has been well dispersed in a polyvinyl chloride resin. According to one embodiment, the method for manufacturing the heat-shielding film includes (1) mixing a polyvinyl chloride resin composition (P) containing the polyvinyl chloride resin (A) using a blender, and (2) adding and further mixing the heat-shielding material with the mixture obtained in step (1 The heat-shielding material contains at least antimony-doped tin oxide micro-particles (B) in an amount in which the mass ratio of the polyvinyl chloride resin (A) to antimony-doped oxidized tin micro-particles (B) is 100 parts by mass to 1.5 to 15 parts by mass. The heat-shielding material is composed of antimony-doped oxidized tin micro-particles (B) alone.

Disclosed is method for preparing ripe persimmon directly on a persimmon tree, comprising the steps of preparing a sealing cover (S1); providing an ethylene generator for generating ethylene gas in the sealing cover (S2); receiving each persimmon, which is dangled on the tree, with the sealing cover in which the ethylene generator is provided (S3); aging the persimmons for a desired period of time in the sealing cover and thus forming the ripe persimmon (S4); and removing the sealing cover and then cleaning the ripe persimmons (S5). Therefore, the ripe persimmons having a good taste and freshness can be simply and efficiently manufactured.

A solar energy greenhouse includes a main structure, a roof structure disposed on the main structure and a plurality of thin-film solar cell assemblies which are disposed on the roof structure in an unequal gap defined there between. The thin-film solar cell assemblies can absorb sunlight and generate electrical energy. The unequal gaps between the thin-film solar cell assemblies are determined from the radiation angle of the sunlight and the position of plants in the solar energy greenhouse, so the amount that the sunlight radiates on the thin-film solar cell assemblies and the plants can achieve a better distribution, which improves the amount of electrical energy generated by the thin-film solar cell assemblies and the rates of growth of the plants.
摘要:
A fastening device, or clamp, for attaching margins of a pair of flexible sheets is provided. The clamp comprises a first strand and a second strand extending along the margins of the sheets. The first and second strands are periodically resiliently biased toward one another to clamp the overlapping margins of the sheets therebetween. The first strand can be straight, while the second strand can undulate. The first strand and the second strand can comprise metallic wires. In one embodiment, the clamp comprises a gripping member that is a resilient C-shaped clamp configured to snap flexible sheets about a substantially straight strand. The clamp preferably is used to attach adjacent flexible sheets to a structural element of a greenhouse.

A hybrid greenhouse comprising a base for installing the hybrid greenhouse on a surface, a space frame delimiting side faces and a top face for enclosing a space above the surface, at least one retractable transparent screen for at least partially shielding the space from the elements when extended, and a netting for preventing entry of insects into the space while allowing air to flow therethrough. The space frame is anchored to the base. The retractable transparent screen is retractably mounted to the space frame. The netting is mounted to the space frame for completely enclosing the space. The at least one retractable transparent screen is mounted between the removable netting and the space.
摘要:
A lightweight construction, especially a greenhouse structure, comprises a plurality of pillars (12) arranged at the periphery of an area of said lightweight construction, said pillars (12) extending obliquely and outwardly so that an upper end (22) of said pillars (12) lies substantially in a vertical plane passing through a respective area border. According to the invention at least one of said pillars (12) comprises a supporting element (14), said supporting element being mounted onto said pillar (12) so as to define a predetermined inclination angle of said pillar (12).
