[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0017] This utility model embodiment provides a soil improvement structure for transplanting large trees based on slow-release nutrients, such as... Figure 1-4 As shown, the soil improvement structure for transplanting large trees based on slow-release nutrients includes: a bottom stone layer 1 laid at the bottom of the tree pit to assist in drainage and aeration of the tree roots; a coarse particle layer 2 placed on top of the bottom stone layer 1 to assist in aeration; a humus layer 3 placed on top of the coarse particle layer 2 to provide initial nutrients to the tree roots; a soil layer 4 laid on top of the humus layer 3 to assist in water retention; and a first slow-release pack 7 and a second slow-release pack 8 buried in the humus layer 3 to assist in the slow release of nutrients.
[0018] In this embodiment, by setting the bottom stone layer 1, the effect of assisting the drainage and aeration of tree roots is achieved, which helps to improve the root growth environment. By setting the coarse particle layer 2, the aeration effect is further enhanced, soil permeability is improved, and root respiration is facilitated. By setting the humus layer 3, the roots of large trees can obtain initial nutrition to meet the nutritional needs in the early stage of transplanting. By setting the soil layer 4, the water retention effect is achieved, maintaining suitable soil moisture. By burying the first slow-release pack 7 and the second slow-release pack 8 in the humus layer 3, the effect of slow-release nutrients is achieved, extending the duration of nutrient supply and reducing the manpower required for regular fertilization.
[0019] In a further preferred embodiment of the present invention, both the first slow-release pack 7 and the second slow-release pack 8 are filled with slow-release fertilizer granules. The first slow-release pack 7 and the second slow-release pack 8 have the same structure. The first slow-release pack 7 consists of a shell 9 for storing slow-release fertilizer granules and a cover 11 for sealing the shell 9 by means of a connecting piece 10.
[0020] In this embodiment, by setting up a first slow-release pack 7 and a second slow-release pack 8, both filled with slow-release fertilizer granules, the effect of providing long-term nutrition to the roots of large trees is achieved, avoiding the trouble of frequent fertilization. By setting the first slow-release pack 7 and the second slow-release pack 8 to have the same structure, the system achieves standardization and facilitates production and use. By setting up a shell 9 to store the slow-release fertilizer granules, the system protects the slow-release fertilizer granules and prevents them from being lost. By setting up a connecting piece 10 and a cover piece 11, the cover piece 11 can be installed on the shell 9 through the connecting piece 10 to seal the shell 9, thereby preventing the slow-release fertilizer granules from being exposed to the soil too early and becoming rapidly ineffective.
[0021] In a further preferred embodiment of the present invention, the shell 9 is provided with an adhesive ring 12 for stabilizing the cover plate 11, the top of the soil layer 4 is provided with a soil-retaining mesh plate 5 for assisting in preventing soil erosion, and the bottom of the soil-retaining mesh plate 5 is provided with a fixing cone 6 that can be inserted into the humus layer 3 for stabilizing the soil-retaining mesh plate 5.
[0022] In this embodiment, by setting an adhesive ring 12 on the shell 9, the effect of stabilizing the cover plate 11 is achieved, ensuring that the slow-release package is not easily dispersed in the soil due to external forces, thus ensuring the stable release of the slow-release fertilizer granules. By setting a soil-retaining mesh plate 5 on the top of the soil layer 4, it plays a role in assisting in preventing soil erosion and preventing rainwater from washing away the soil, thus protecting the growth environment of the tree roots. By installing a fixing cone 6 at the bottom of the soil-retaining mesh plate 5 and allowing it to be inserted into the humus layer 3, the soil-retaining mesh plate 5 can be stably fixed on the soil and is not easily blown away or displaced by the wind, further enhancing its effect in preventing soil erosion.
[0023] In a further preferred embodiment of the present invention, the fixed cone 6 is provided with a drainage channel for providing rapid irrigation water introduction, and the fixed cone 6 is provided with a drainage hole 13 for discharging irrigation water, and the number of drainage holes 13 is not less than three to help increase the area of soil that is rapidly moistened.
[0024] In this embodiment, by setting a drainage channel on the fixed cone 6, the irrigation water can be quickly introduced, which helps to improve irrigation efficiency and ensures that water quickly reaches the roots of the tree. By setting drainage holes 13 on the fixed cone 6, the irrigation water is drained, allowing the water to permeate evenly into the surrounding soil. By setting no less than three drainage holes 13, the area of soil that can be quickly moistened is further increased, ensuring that the soil around the roots of the tree can be adequately moistened. This design not only optimizes the irrigation effect and makes water use more efficient, but also helps the tree to recover and grow quickly after transplanting, improving the survival rate.
[0025] In a further preferred embodiment of this utility model, the shell 9, the connecting piece 10, and the cover 11 are all made of PBAT material, and the thickness ratio of the shell 9 of the first slow-release package 7 to the shell 9 of the second slow-release package 8 is 1:2.
[0026] In this embodiment, by using PBAT material for the shell 9, connecting piece 10, and cover piece 11, an environmentally friendly and biodegradable effect is achieved, which helps reduce environmental pollution and conforms to the concept of sustainable development. At the same time, as the biodegradable slow-release fertilizer is released sequentially, a nutrient slow-release effect is achieved. By setting the thickness ratio of the shell 9 of the first slow-release pack 7 to the shell 9 of the second slow-release pack 8 to 1:2, the nutrient release rate is differentiated. The thicker shell 9 allows the nutrient release time of the second slow-release pack 8 to be relatively later, while the thinner shell 9 allows the nutrient release time of the first slow-release pack 7 to be relatively shorter. Thus, according to the nutrient needs of the tree at different growth stages, a continuous and reasonable supply of nutrients is achieved.
[0027] In a further preferred embodiment of this utility model, the bottom stone layer 1 is composed of a mixture of perlite particles and vermiculite particles, and the coarse particle layer 2 is composed of river sand and peat soil. The river sand and peat soil in the coarse particle layer 2 can seep into the gaps of the bottom stone layer 1.
[0028] In this embodiment, by setting a bottom stone layer 1 composed of a mixture of perlite particles and vermiculite particles, a good drainage and aeration effect is achieved. The porous structure of perlite and vermiculite particles facilitates rapid water drainage while ensuring air circulation, creating a healthy growth environment for tree roots. By setting a coarse-particle layer 2 composed of river sand and peat moss, the soil structure is further optimized. River sand increases aeration, while peat moss provides certain nutrients and helps retain water. By allowing the river sand and peat moss in the coarse-particle layer 2 to seep into the gaps of the bottom stone layer 1, the two layers are more tightly bonded, forming a more coherent drainage and aeration channel. This enhances the stability and functionality of the entire soil improvement structure, enabling the roots of large trees to better adapt to the new environment after transplantation and promoting their rapid recovery and growth.
[0029] In a further preferred embodiment of this utility model, the humus layer 3 is composed of leaf mold, peat moss, garden soil and organic fertilizer, and the ratio of leaf mold, peat moss, garden soil and organic fertilizer is 4:3:2:1.
[0030] In this embodiment, by setting up a humus layer 3 composed of leaf mold, peat moss, garden soil, and organic fertilizer, the effect of providing rich and balanced nutrition to the roots of large trees is achieved. Leaf mold is rich in humus, which helps improve soil structure. Peat moss has good water and fertilizer retention properties. Garden soil provides a basic soil foundation, and organic fertilizer increases soil fertility. By mixing these four components in a ratio of 4:3:2:1, a scientific ratio and complementary advantages are achieved, so that the humus layer 3 has both good air permeability and water retention, and can provide sufficient nutrients for large trees.
[0031] In a further preferred embodiment of the present invention, a layer of fallen leaves is laid between the soil-retaining mesh plate 5 and the soil layer 4 to reduce the efficiency of water evaporation, and the soil-retaining mesh plate 5 is provided with a locking slot that is fastened to the outside of the tree trunk.
[0032] In this embodiment, by laying a layer of fallen leaves between the soil-retaining mesh 5 and the soil layer 4, the efficiency of water evaporation is reduced. The fallen leaves act as a natural covering, effectively reducing the loss of soil moisture and maintaining a relatively moist environment for the roots of the tree. This helps the tree absorb water better after transplanting. By setting a locking point on the soil-retaining mesh 5 to secure the relative position of the soil-retaining mesh 5 and the tree, the relative position of the soil-retaining mesh 5 and the tree is stabilized, preventing the soil-retaining mesh 5 from shifting due to external factors (such as wind). This allows it to continuously and stably perform its function of assisting in preventing soil erosion, while also providing some auxiliary fixation for the tree, enabling the tree to grow more stably after transplanting.
[0033] In summary, compared with related technologies, this device, through its multi-layered structure including a bottom stone layer 1, a coarse particle layer 2, a humus layer 3, a soil layer 4, and a slow-release pack, achieves multiple objectives such as improving the root growth environment of large trees, providing initial and continuous nutrition, assisting in water retention, enhancing soil permeability, preventing soil erosion, and optimizing irrigation effects. These designs work together to not only improve the survival rate of large trees after transplantation but also reduce the frequency of manual fertilization and irrigation, lower maintenance costs, and conform to the concept of environmental protection and biodegradability.
