The present invention provides a method of using plant material to simultaneously control weeds and plant target plants, including the following steps: covering the carrier with plant material with a thickness of 0.1˜12 cm to form a plant material layer, controlling the water content of the plant material during the covering period, immediately before planting and after planting, planting the target plant on the surface of the plant material layer or in the plant material layer. The subject method could make full use of plant resources, control weeds when they are the most vulnerable, and produce a synergistic effect of different planting methods for different target plants. At the same time, the method achieves low cost and ensures the survival rate of planting target plants.

A method for making a dyed mulch composition or a dyed growing medium, the method comprising combining tree bark including one or more pigments and/or pigment precursors and wood components together to form an initial composition; heating the initial composition at a temperature greater than about 149° C. under steam in a pressurized vessel; processing the initial composition through a refiner with a plurality of opposing disks, the refiner separating the tree bark and wood components into fibers and separating the fibers from each other; and dyeing the wood components by the one or more pigments and/or pigment precursors while the tree bark and the wood components are being separated into fibers in the refiner to obtain dyed fibers.

A woven fabric formed of fabric fibers or threads coated with a hydrogel, wherein said hydrogel is not crosslinked or is partially crosslinked to the fabric fibers or thread, wherein the hydrogel has a number of excess reactive molecules that are available for a reaction with one or more molecules solvated in an aqueous solution, and wherein the reactive molecules of the hydrogel can reversibly bond with the molecules solvated in an aqueous solution, such that the reactive molecules of the hydrogel attract the molecules solvated in aqueous solution when the hydrogel coated fabric substrate is exposed to an aqueous solution.

A plant irrigation device includes a support that surrounds a plant and provides an opening through which the plant extends. A drip tube is attached to the support and connectable to a water source. The drip tube has a series of spaced apart apertures or water emitters along a length thereof permitting water to exit the drip tube and into the ground surrounding the plant.

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.

A sapling protector having a truncated cone-shaped metal tube formed from a flexible electrolytic tinplate and/or electrolytic chromium coated steel metal sheet is provided. The sapling protector also includes at least one fastener and is perforated with a plurality of holes. The truncated cone-shaped metal tube of the sapling protector also has a coating on the outer surface of the metal sheet and the edges of the metal sheet are hemmed so as to limit the presence of sharp edges and provide a safe device. The sapling is recyclable, ecofriendly, reusable, and safe; it may be used for multiple growing seasons; and may be transferable between new saplings over the course of multiple years. The corresponding method of protecting a tree sapling and sapling protector kit are also provided.

A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.

A protective tree tube has an elongated hollow body that is made of a biodegradable material, and has holes formed in the wall of the tube. The tube can be filled, at a bottom portion, with drainage material, and on top of the drainage material a planting material can be provided in which the root ball of a tree is placed. Upon placing the protective tree tube with the tree into a planting hole, the protective tree tube ca be buried and thereafter the tree will commence forming new rootage and become established.

A ground cover material for use in horticulture has on one side a low white layer comprising a transparent or translucent polymer and a low amount of a white pigment or pigments, and on an opposite side a metallized layer. In use the material is placed beneath fruit trees for example, and provides a balance of direct and diffuse reflection of incident solar radiation back to the fruit trees.

The present utility model relates to the technical field of agricultural planting equipment, in particular to a sectional arched tunnel connected by tension, which comprises a first connecting rod and a second connecting rod between which a metal connector is connected. Both sides of a surface of the metal connector are provided with threaded connection holes, and both ends of the metal connector are provided with connecting holes. The present utility model can adapt to different ridge widths by changing number and bending amplitude of the connecting rods and it is convenient to connect without pressing, so as to meet requirements for different ridge widths.
