Description

Technical Field

[0001] This utility model relates to the field of fruit tree cultivation technology, and in particular to a composite weed-blocking device for reducing weeding and nutrient loss in fruit tree cultivation. Background Technology

[0002] In the process of fruit tree cultivation, weeds easily compete with fruit trees for nutrients in the soil and artificially applied nutrient substrate. Existing weed control methods mostly rely on manual removal or chemical herbicides. At the same time, due to the lack of effective enclosure, nutrients in the soil and nutrient substrate are often lost in large quantities due to competition from weeds, rainwater erosion, or natural volatilization, which increases weed control costs and reduces nutrient utilization efficiency.

[0003] Regarding the aforementioned technologies, the inventors believe that fruit tree cultivation urgently needs to address the problem of easy nutrient loss from soil and nutrient substrates. Utility Model Content

[0004] To address the problem of easy nutrient loss from soil and nutrient substrates, this application provides a composite weed-blocking device for reducing weeding and nutrient loss in fruit tree cultivation.

[0005] The composite weed-blocking device for reducing weeding and nutrient loss in fruit tree cultivation provided in this application adopts the following technical solution: A composite weed barrier device for reducing weeding and nutrient loss in fruit tree cultivation includes an annular weed barrier panel made of polyethylene plastic, which is used to surround the base of the fruit tree trunk to form a cultivation area that blocks external weeds from intruding. A nutrient substrate layer is laid in the cultivation area, which is a mixture of coconut coir and bark and is laid on the soil surface.

[0006] Optionally, the mass ratio of coconut coir to bark in the nutrient substrate layer is 3:1-2:1, and the thickness of the nutrient substrate layer is 5cm-10cm.

[0007] Optionally, the height of the grass barrier is 20cm-30cm.

[0008] In summary, this application includes at least one of the following beneficial technical effects: This invention uses a ring-shaped weed barrier to prevent external weeds from invading, reducing the labor cost and frequency of weeding. At the same time, the nutrient substrate layer, a mixture of coconut coir and bark, not only retains soil nutrients and provides slow-release nutrition for fruit trees, but also physically covers and inhibits the germination of weeds within the enclosed area, and reduces nutrient loss due to volatilization and rain erosion. Thus, while reducing weeding operations, it effectively preserves soil and substrate nutrients, significantly improving the nutrient utilization efficiency during fruit tree cultivation.

[0011] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” and “one or more” refer to one, two, or more than two. The term “and / or” is used to describe the relationship between related objects, indicating that three relationships may exist; for example, A and / or B can indicate: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0012] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0013] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0014] This application discloses a composite weed-blocking device for reducing weeding and nutrient loss in fruit tree cultivation, referring to... Figure 1 and Figure 2The system includes a ring-shaped weed barrier 2, which is made of rigid and aging-resistant green polyethylene plastic. When in use, it is placed around the bottom of the trunk of the fruit tree 1 to enclose a cultivation area for the fruit tree to grow and to prevent external weeds from invading. Within the cultivation area enclosed by the weed barrier 2, a nutrient substrate layer 3 is laid. The nutrient substrate layer 3 is made of coconut coir and bark mixed in a mass ratio of 3:1-2:1 and is laid on the surface of the soil 4 in the cultivation area with a thickness of 5cm-10cm.

[0015] Reference Figure 1 and Figure 2 The grass barrier 2 is made of polyethylene plastic injection molding, which has good bending resistance and weather resistance. The height is 20cm-30cm, and the inner diameter can be adapted according to the specifications of the fruit trees. For example, the inner diameter of 40cm-60cm is selected for young trees, and the inner diameter of 80cm-120cm is selected for mature trees.

[0016] Reference Figure 1 and Figure 2 In the nutrient substrate layer 3, coconut coir and bark need to be crushed in advance. The bark particles should be ≤2cm in diameter and the coconut coir should be loose and fibrous. After being mixed evenly at a mass ratio of 3:1, they are laid on the cultivation area enclosed by the straw barrier 2. The preferred thickness is 8cm. In the rainy season, the thickness can be increased to 10cm to enhance water and fertilizer retention capacity.

[0017] In use, first place the ring-shaped weed barrier 2 around the bottom of the trunk of the fruit tree 1, leaving an appropriate gap between the inner ring of the barrier 2 and the bottom of the trunk to accommodate the growth of the fruit tree 1. Then, press the bottom edge of the barrier 2 into the soil 4 and fix it in place to create a dedicated cultivation space. Subsequently, evenly spread a nutrient substrate layer 3 composed of coconut coir and bark in this space. The thickness of the nutrient substrate layer 3 is 5cm-10cm. The barrier 2 blocks external weeds from invading, reducing the frequency of weeding and labor costs. The nutrient substrate layer 3 composed of coconut coir and bark can not only retain soil nutrients and provide slow-release nutrients for the fruit tree, but also physically cover and inhibit the germination of weeds in the area. It can also reduce the loss of nutrients due to volatilization and rainwater erosion, thereby effectively preserving soil and substrate nutrients and improving nutrient utilization efficiency while reducing weeding operations.

[0018] The above are merely preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included within the protection scope recorded in the claims.
