摘要:
A method of reducing cold injury or damage to plants such as peanut, citrus trees, peaches, strawberries and other plants susceptible to cold injury such as frost or freezing comprises applying a pyridylaniline active agent such as fluazinam to the plant in an amount effective to reduce cold injury to the plant.

A greenhouse on a support structure on posts with a hanging foil roof that can be opened, wherein the foil covering that forms the roof remains completely below the support structure formed by lattice girders in every position by being suspended form the rails on the underside of, and longitudinally to, the lattice girders is movable between the open and the closed position.
摘要:
A protective winter turf cover is formed with a layered polyethylene laminated sheet with each layer having force striations running at an angle to the edge of the sheet and with the force striations of one layer at an angle to the force striations of the adjacent layer, the resulting turf cover being lightweight, compactly foldable, and substantially impermeable to water.
摘要:
Antifungal polypeptides, isolated from Medicago plants, are shown to control fungal damage to plants. DNA encoding the polypeptides was cloned into vectors for transformation of plant-colonizing microorganisms or plants, thereby providing a method of inhibiting fungal growth on plants. The polypeptides can be formulated into compositions useful in controlling undesired fungi.
摘要:
Composite material for the screening of radiation, comprising a polymer, an additive and the customary stabilizers and processing aids necessary for the particular polymer. The additive is preferably an interference pigment.
摘要:
A sunshade includes an intermediate net portion having mono filament circular weft yarns interlaced with flat warp yarns, two stringing sections which are formed on two sides of the intermediate net portion and each of which has a limit portion which is interposed between two weft-free portions and which is folded to lay the weft-free portions one over the other, two opposite drape portions extending from the stringing sections, respectively, and a pair of strings threading through and fastening together the weft-free portions.
摘要:
An organic substrate for controlling vegetation is manufactured from recycled waste paper, cotton fiber and cotton gin waste, and gypsum. The recycled waste products are combined to form a slurry mixture for processing by conventional paper making machinery into a substrate that may be used in sheet form or comminuted pieces to control weed growth in horticultural applications and serve as a carrier substrate for germinating seeds and growing select vegetation species.
摘要:
This invention discloses generally enclosure structures for protecting plants. More specifically, this invention discloses a method and enclosure for thermally protecting plants from extreme temperatures and physically protecting plants from wind and other physical assaults. The present invention provides plants with a flexible yet stable fluid fillable enclosure formed by a plurality of vertical tubes interconnected by a basal annular ring.
摘要:
A protective polyethylene canopy, in the order of 100 to 110 inches in width and approximately 1.3 mils thick, is placed over trellised grapevines and fastened by the disclosed tie downs at the respective canopy sides. To form the tie downs, the side edges of the canopy are gathered and folded back upon themselves at intervals up to 2 inches. Thereafter, tape, in the form of adhesive labels, is placed over the folded edges so as to capture the folded and gathered side film edges. The label and folded film is transpierced, typically by a worker using grape clippers holding attached twine. Once transpierced and threaded with the twine, the twine is tied to the label and the canopy material, and then secured at its remote end to tightly secure the canopy overlying the trellis and vines growing on the trellis.
