The present invention is directed to a passive solar greenhouse for controlling the greenhouse's interior environment and maximizing photosynthetic metabolism within the plants grown therein through regulation of sunlight, temperature, humidity, and carbon dioxide levels and methods optimizing plant growth conditions by using passive solar greenhouse of the present invention. Generally the greenhouse has a sloped glazed face which faces substantially true south in the Northern hemisphere and substantially true north in the Southern hemisphere with a predetermined slope angle designed to maximize incident solar radiation (insolation) and increase the interior temperature during the colder months of the year while reducing overheating during the warmer months of the year.

The present invention relates to an assembly, comprising a plant pot (258) having a bob tons (260) and at least one side wall (264), extending from the bottom up to a top rim and at least one hole (268) which is arranged in or at least near the bottom, at least one wick (30) extending from below the bottom and through the hole and a container (256), dimensioned to accommodate at least a bottom portion of the plant pot comprising the hole through which the wick extends out of the plant pot. The container and the plant pot in an assembled state define a reservoir to accommodate fluid, such as water, for the plant to be drawn up through the wick during at least one of growing, transporting and display for sale of a plant in the plant pot, which is accommodated in the container. An overflow (284) with a controllable valve (288) may function to distinguish between a stationary state of the assembly and transport thereof.

The present invention provide a light-scattering fluororesin film for agricultural applications which can be used as a covering material for an agricultural house or the like, is excellent in uniformity of color or the like of crops cultivated, can reduce the occurrence of leaf scorch, seedling blight or the like, and can cultivate the crops at high productivity. Specifically, the invention provides a light-scattering fluororesin film for agricultural applications that gives a ratio of scattered light with a scattering angle of 5.5 to 10° being 5% or higher relative to the total transmitted light.

The present disclosure relates to a multilayer film capable of releasing an active ingredient, for example a pesticide. The film has a bottom or internal layer composed in part of a water-soluble polymer fraction containing the active ingredient, and a top or external layer. The bottom or internal layer may have a water-insoluble fraction in addition to the water-soluble polymer fraction. Relative proportions of the water-soluble polymer fraction and of the water-insoluble fraction provide a pre-determined time of release of the active ingredient when the multilayer film is exposed to humidity and/or moist conditions. The present disclosure also relates to methods of making the multilayer film and to uses of the film.
摘要:
The invention refers to a greenhouse screen comprising strips of film material that are interconnected by a yarn framework of transverse threads and longitudinal threads to form a continuous product, wherein the yarn framework is thermally bonded to at least one side of the strips of film material, wherein also those parts of the yarn framework that is thermally bonded to the strips have liquid-transporting capacity by capillary action. The amount of yarn in the yarn framework interconnecting and holding the strips can herewith be reduced.
摘要:
An irrigation device includes: a nozzle discharging liquid; a cover preventing the liquid discharged from the nozzle from splattering around the container; and a moving mechanism moving the cover between a first position and a second position. When moved to the first position, the cover covers space above the container. When moved to the second position, the cover is removed from the space above the container and the space is uncovered. The moving mechanism moves the cover (i) to the first position when the liquid is supplied to a plant, and (ii) to the second position when the supplying of the liquid to the plant ends.
摘要:
Methods for fumigating soil include providing a fumigant including at least one volatile substance into or onto soil and applying over the soil a multilayer polymeric film to form a vapor barrier between the fumigant-treated soil and the atmosphere to at least partially contain the fumigant. The multilayer film includes at least one barrier layer comprising at least one vinylidene chloride polymer and protecting layers on each side of the barrier layer. The multilayer film preferably has at least one UV protecting layer and optionally at least one reflective layer.
