Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea tree cultivation technology, and in particular to a device for suppressing weeds in tea gardens. Background Technology
[0002] Weeds are an integral part of biodiversity in tea garden ecosystems, characterized by their resilience, rapid growth and reproduction, and large biomass. During their growth, they compete with tea trees for resources such as water, fertilizer, space, and sunlight, severely impacting tea yield and quality. They can also become hosts for tea garden pests and diseases, promoting their proliferation and spread. Furthermore, weed infestations hinder mechanized harvesting and pruning in tea gardens. Studies have shown that tea gardens without weed control experience a yield reduction of approximately 14.98% to 19.84% compared to those with controlled weed control.
[0003] Current weed control methods primarily rely on chemical herbicides, but these methods inevitably leave toxic residues, which can affect tea quality. Furthermore, the high cost of herbicides increases tea production costs.
[0004] Therefore, a device for suppressing weeds in tea gardens is proposed to avoid the chemical pollution caused by using chemical herbicides. Utility Model Content
[0005] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a device for suppressing weeds in tea gardens.
[0006] The technical solution of this utility model is as follows:
[0007] A device for suppressing weeds in tea gardens includes tea tree planting strips, shading strips, and a set of symmetrically arranged shading components. The tea tree planting strips are strip-shaped areas extending in a predetermined direction for planting tea trees. The shading strips are arranged between the tea tree planting strips, parallel to and alternating with the tea tree planting strips. The shading components include a support frame and a retaining frame. The bottom of the support frame is fixed in the soil by anchor rods, and the top of the support frame is connected to the retaining frame by hinges. The top surface of the retaining frame is covered with a shading net.
[0008] Preferably, the shading strip includes a bottom shading layer and a retaining layer; the bottom shading layer is a first covering layer made of an opaque or weakly transparent organic covering; the retaining layer is a retaining net laid on the bottom shading layer.
[0009] Preferably, the width of the shading strip effectively suppresses the growth of weeds in the adjacent edge area while allowing tillage machinery to pass through the shading strip area; the material of the bottom shading layer is selected from black plastic sheeting, biodegradable film, thick bark, sawdust, straw, coconut coir or a combination thereof; the structural configuration of the shading strip suppresses the growth of weeds in the area below and adjacent to it by physically blocking light.
[0010] Preferably, the inner side of the top of the column frame is provided with a limiting diagonal brace to abut against the support frame.
[0011] Preferably, the top of the anchor bolt is provided with an anchor bolt baffle laid on the ground.
[0012] Preferably, the bottom light-shielding layer is a black plastic sheet, and micropores or gaps are evenly opened on it to allow rainwater to infiltrate.
[0013] Preferably, the bottom light-shielding layer has a double-layer structure, with the lower layer being a degradable film or black plastic sheet, and the upper layer being wood chips, straw, or coconut coir with a thickness of not less than 2cm.
[0014] The present invention has the following beneficial effects: The present invention uses a shading component to cover the weed growth area, thereby inhibiting weed growth by controlling light and blocking the photosynthesis of weeds. At the same time, a shading strip is used to further inhibit weeds. The shading strip includes a bottom shading layer and a holding layer. The width of the shading strip effectively covers the area where weeds grow on the adjacent edge, while allowing farming machinery to pass through the shading strip area. The structural configuration of the shading strip inhibits the growth of weeds in the area below and adjacent to it by physically blocking light. Attached Figure Description
