An agricultural netting material has a construction profile across the width of the netting in which one or more construction elements varies across the width of the netting, a construction element in a first region of at least 20 cm width of the netting being different to the construction element in a second region of at least 20 cm width of the netting, the construction element being one of a yarn thickness, a yarn width, a yarn transmittance, a yarn pigmentation, a yarn reflectance, a yarn absorbance, a netting aperture size, a netting construction pattern and a netting cover factor.

A tree net assembly includes a pole vertically oriented and positioned adjacent to a plant. Each of a pair of globes is slidably positioned around the pole, and each of the globes has a plurality of wells each extending toward a center of a respective one of the globes. each of a pair of rods is comprised of a resiliently bendable material. Each of the rods is removably coupled between the globes when the globes are positioned on the pole. The globes are spaced apart from each other a distance less than a length of the rods. The rods curve outwardly from the pole between the globes such that the rods define a sphere surrounding the plant. A net is positionable around the rods to surround the plant.

A refrigerating cultivation greenhouse is disclosed, including a support pedestal where fixed parts embedded underground. A connection block is fixed on the fixed parts. A greenhouse framework fixed on the connection block. Plastic covering films structured by two layers are disposed on an outer layer and an inner layer of the framework. A refrigeration system includes a refrigerant circulation system, an air box, an air outlet pipe communicating with the air box and interior of the greenhouse, and an air inlet pipe communicating with the air box and interior of the greenhouse. The air inlet pipe may be provided with an exhaust fan. Heat exchange occurs between refrigerant and hot air within the air box. In such a way, the air is conveyed into the air box.

The present disclosure relates to a plant cultivating apparatus. The plant cultivating apparatus includes an elastic housing having an inner cavity, the elastic housing being provided with first and second openings at upper and lower ends thereof in communication with the inner cavity; a top structure provided at the upper end of the elastic housing to close the first opening; a bottom structure provided at the lower end of the elastic housing to close the second opening and configured to hold a root of a plant; and a lifting structure provided between the top structure and the bottom structure, the lifting structure being capable of stretching and compressing in the vertical direction, thus driving the top structure to move up or down with respect to the bottom structure.

Crop protection netting for covering trees or other plants for insect and bird exclusion is of a knitted mesh construction, comprising knit intersections in the netting and connecting yarn portions between the yarn intersections which extend substantially linearly between intersections. The netting is lightweight and stretchable in multiple directions.

A plant cover device (630, 730) may include an enclosure (631, 731) having panels (204, 634A) coupled together to define a plant-receiving cavity. Each of the panels (204, 634A) has a major mesh surface (635A), and a seam (208, 302, 636A) extending along a peripheral edge (646A) of the major mesh surface (635A), Adjacent panels (634A) are coupled together at respective seams (636A). The enclosure (631, 731) may include a first fastener (637, 640) adjacent the peripheral edge (646A) of a respective panel (634A, 634B). The plant cover device (630, 730) may have a base (100, 632) coupled to the enclosure (631, 731) and including a solid major surface (638) extending radially outward, and a second fastener (637, 640) carried by the solid major surface (638) and extending radially. The plant cover device (630, 730) may also include a support (633, 733) extending vertically from a ground surface to an apex of the enclosure (631, 731). The first fastener (637, 640) and the second fastener (637, 640) may be aligned and configured to provide access to the plant-receiving cavity.

Protective bags having bag bodies formed by or with meshed fabrics can be used to protect potted plants from plant bugs. The protective bags are sized and shaped to protect both the plant top section and the plant root system or just the plant root system. Accessible seams or windows can be provided to access the interior of a bag for watering, feeding plant food, and/or pruning purposes. The protective bags can be sized and shaped to work with potted plants using soils or hydroponic systems.

Disclosed herein is a device for protecting and covering plants. More specifically, the present invention generally relates to a device and method of use for covering and protecting plants from environmental elements by utilizing a height and width adjustable material covering. In one embodiment the device is comprised of a vertical support member, arm members, slider members, and covering members. In another embodiment, the device for protecting and covering plants is further comprised of cap members.

A cover for plants includes, a frame which has a rectangular top tier of rods, a rectangular bottom tier of rods, four vertical supports which connect the top tier of rods to the bottom tier of rods, and four sides. The cover further includes a side cover which is shaped and dimensioned to cover the four sides of the frame, the side cover has four sides, a top, four top corners, and a bottom. The side cover includes four corner closures disposed at the four top corners. The side cover includes a side closure, and a skirt disposed at the bottom. A top cover is shaped and dimensioned to cover the top of the side cover and the top tier of rods. A crown frame is shaped and dimensioned to fit around the top cover.

A plant cover device may include an enclosure having an upper end, a lower tubular end opposite the upper end, and a medial seam coupling the upper end and the lower tubular end. The upper end may include panels coupled together to partially define a plant-receiving cavity therein. Each of the panels may have a major mesh surface, and a panel seam extending along a peripheral edge of the major mesh surface, adjacent panels being coupled together at respective panel seams. The lower tubular end may include a major mesh surface and having a first end and a second end opposite the first end, the first end being coupled to the medial seam. The lower tubular end may also partially define the plant-receiving cavity therein. The enclosure may have a curved flexible support carried by the medial seam, and a pole extending vertically from a surface to an apex of the enclosure.
