Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically a castor bean root and stem protective net for mine soil remediation. Background Technology

[0002] Castor bean is a fast-growing plant belonging to the Euphorbiaceae family. It has strong tolerance to the heavy metal copper (Cu), and is characterized by its well-developed root system, tolerance to poor soil, and high economic value. Furthermore, castor bean is highly adaptable to various soil types and can grow in slightly saline-alkali land. Therefore, castor bean is used in mine soil remediation.

[0003] Large-scale mining activities around open-pit mines often lead to extensive soil stripping and erosion, resulting in loose soil structure and a significant decrease in water retention capacity, which is detrimental to the normal production of castor beans. Furthermore, the mine soil contains fewer microorganisms, resulting in a slower decomposition rate of organic matter such as fallen leaves, making it difficult for nutrients in the soil to cycle. Therefore, a protective net for castor bean growth is needed. Utility Model Content

[0004] The purpose of this invention is to provide a castor bean root and stem protective net for mine soil remediation, which can cover the surface of mine soil, reduce soil erosion, add fertilizer to the soil, improve soil microbial activity, promote the decomposition of organic matter in the soil, and thus improve the remediation efficiency of mine soil.

[0005] To achieve the above objectives, a castor bean root protection net for mine soil remediation is provided, comprising an edge rope and a net body. The edge rope is fixedly connected to the outside of the net body, with the net body located in the middle of the edge rope. A plurality of biodegradable fertilizer blocks are fixedly connected at equal intervals at the joints of the net body, and the biodegradable fertilizer blocks penetrate through the joints of the net body. Each biodegradable fertilizer block consists of a first shell, microbial fertilizer, and a second shell. The first and second shells are identical cylindrical hollow structures, with one end of each shell contacting and communicating with the other. The first and second shells are fixedly connected by an adhesive. The microbial fertilizer is disposed within the first and second shells, which are made of PBAT plastic. The net body is located at the joint of the first and second shells and penetrates through them. This method can cover the surface of mine soil, reduce soil erosion, and add fertilizer to the soil, increasing soil microbial activity and promoting the decomposition of organic matter in the soil, thereby improving the remediation efficiency of mine soil.

[0006] According to the aforementioned castor bean root protective net for mine soil remediation, both the edge ropes and the net body are made of hemp rope as the weaving material. The use of hemp rope for the edge ropes and net body allows the protective net to decompose within 3-4 months after installation during the rainy season, improving mine soil fertility and preventing environmental pollution.

[0007] According to the aforementioned castor bean root protective net for mine soil remediation, each of the four corners of the side rope is fixedly connected with a fixing rope loop. The fixing rope loops facilitate the securing of the protective net, ensuring its effectiveness in preserving the mine soil.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The netting helps retain soil and reduce water and soil erosion. The biodegradable fertilizer blocks release microbial fertilizer into the soil after natural degradation, replenishing the nutrients needed for castor bean growth in the following year and promoting the decomposition of organic matter in the soil, thus improving the remediation effect on mine soil.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a castor bean root and stem protective net for mine soil remediation, comprising a side rope 1 and a net body 3. The side rope 1 is fixedly connected to the outside of the net body 3, and the net body 3 is located in the middle of the side rope 1. Both the side rope 1 and the net body 3 are made of hemp rope as the weaving material. The use of hemp rope as the material for the side rope 1 and the net body 3 allows the protective net to decompose after 3-4 months of rainy season after being laid, improving the fertility of the mine soil and avoiding environmental pollution. Several biodegradable fertilizer blocks 4 are fixedly connected at equal intervals at the joints of the net body 3, and the biodegradable fertilizer blocks 4 pass through the joints of the net body 3. The biodegradable fertilizer block 4 is composed of a first shell 5, microbial fertilizer 6, and a second shell 7. The first shell 5 and the second shell 7 are identical cylindrical hollow structures, and one end of the first shell 5 and the second shell 7 are in contact with each other and connected. The first shell 5 and the second shell 7 are fixedly connected by an adhesive. Microbial fertilizer 6 is placed in the first shell 5 and the second shell 7. The first shell 5 and the second shell 7 are made of PBAT plastic material, so that the first shell 5 and the second shell 7 can decompose in the natural environment after 5 months. Combined with the growth cycle of castor beans, it can increase the activity of microorganisms in the soil after the castor beans begin to shed their leaves in autumn, and promote the decomposition of fallen leaves in the soil. The net body 3 is located at the connection end of the first shell 5 and the second shell 7, and the net body 3 runs through the first shell 5 and the second shell 7.

[0018] Working principle: When in use, the protective net is laid on the surface of the mine soil and fixed to the ground by the fixing rope ring 2 to prevent soil erosion. Castor seeds are sown in the mesh of the protective net. After a period of time, the hemp rope edge rope 1 and the net body 3 are degraded first, which improves the nutrition for castor growth. Then, the first shell 5 and the second shell 7 of the biodegradable fertilizer block 4 are degraded in summer and autumn. The microbial fertilizer 6 inside enters the soil, improves the microbial activity in the mine soil, promotes the decomposition of organic matter in the mine soil, and improves the remediation effect of the mine soil.

[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
