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).

The present invention concerns an elongated sheet (1) for covering 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 at least one ventilation opening (6) comprises two opposite corners (29, 20) of the ventilation opening (6) in a cross direction (Q) of the sheet (1) extending at least substantially orthogonally to the longitudinal sheet direction (L).

A method and apparatus for cultivating vegetation at an inhospitable location includes rooting immature vegetation in a mat combined with a super absorbent polymer (“SAP”) and, in embodiments, fertilizer, sand, and/or soil; providing a water reservoir below grade at the inhospitable location; placing the mat at the inhospitable location over the water reservoir; extending at least one wick from the mat to the water reservoir; and covering the mat with a perforated, transparent or semi-transparent cover. The wick can be infused with nutrients and/or fertilizer. Hollow tubes can extend downward from the mat to enable excess water to flow into the reservoir. The hollow tubes can surround the wicks. The transparent cover can be placed on or suspended above the mat. SAP, seeds, and/or fertilizer can be placed between mats in a stack. A water distribution system can be included for supplying additional water to the water reservoir.

One exemplary aspect relates to a system for tying and stabilizing a plastic cover film for agricultural crops such as soft fruit covers. Cultivation in covered areas has been particularly developed in recent decades. The state of the art includes glass panes, greenhouses, and special plastic coverings for soft fruit. With the prior art, the placement, fastening and fixing of the plastic film is achieved with ropes or with elastic cords or with soft PVC tubing. However, the cost of binding the plastic film is significant as skilled staff and considerable amounts of man hours are required to tie the plastic film to the supporting structure. Tying the film, in most cases, is carried out by employing knots on simple eyelets or grommets, that the plastic films bear and, respectively, with knots on the wire ropes of the structure.

A controlled environment agriculture system is disclosed, in which the system includes a reflective curtain (100, 600) having a porous membrane with a reflectance value of at least 90%.

Provided herein are devices, systems, and methods for sunlight delivery, shoot positioning, canopy division, positioning fruit into distinct zones, managing fruit maturity and quality, rain, wind, and hail protection, and reducing canopy management and harvest labor of one or more plants on a trellis comprising one or more panels and a standoff, wherein the panels divide the growth of plant shoots on the trellis, thereby modifying growth or development of the plants. In some embodiments, the panels collect light energy and direct the collected light energy to the plants, thereby modifying growth or development of the plants and their producing of fruit.

Described herein is a pillar knitted crop netting comprising widely spaced knitted pillars and crop netting materials comprising a region(s) having such construction. Also described herein are crop nettings comprising yarns defining apertures to form the netting wherein said apertures have a plurality of sides formed by yarn sections and at least one of those yarn sections may be relatively slack when the netting is held taut in lengthwise and widthwise directions. The above nettings may have advantageous hail passage performance.

Disclosed herein are composite materials that comprise one or more copper-cysteamines capable of converting higher frequency, lower wavelength radiation into visible light. As used, the produced visible light enhances the amount of visible light already present from natural or artificial sources.

A portable shade shelter has a plurality of canopies including at least a first canopy and a second canopy. The first canopy is disposed over the second canopy, and the first canopy is capable of being spaced apart from the second canopy in a vertical direction such that air is capable of flowing between the first canopy and the second canopy. Each of the first canopy and the second canopy includes a plurality of openings configured to permit air and light to pass through the respective first canopy and second canopy.

The invention refers to a tying system employing an accessory bearing a quick attachment hook, for tying a plastic cover film for agricultural crops such as soft fruit covers. Cultivation of soft fruits in covered space has been growing in recent decades. Several solutions have been developed including greenhouses or gable systems. The placement, fastening and fixing of the plastic film is achieved with ropes, elastic cords or soft PVC tubing. However, the cost of binding the plastic film is significant as skilled staff and considerable amounts of man hours are required to tie the plastic film to the supporting structure. Tying the film, in most cases, is carried out by employing knots on grommets that the plastic films.
