Description

Technical Field

[0001] The present invention belongs to the technical field of ecological planting and breeding circulation, and in particular relates to a cable-stayed suspension bridge type three-dimensional ecological planting and breeding circulation system. Background Art

[0002] As an important part of ecological civilization construction, the core content of green agricultural development is green planting and breeding cycle. To promote green planting and breeding cycle, we must first coordinate ecological environmental protection with economic and social development, and coordinate the import and export of planting and breeding industries; secondly, we must fully implement the comprehensive resource utilization of agricultural waste, especially the harmless treatment and resource utilization of livestock and poultry manure, so as to give full play to its role in promoting green agricultural development.

[0003] In recent years, my country's animal husbandry has continued to develop steadily, and the level of large-scale breeding has significantly improved, ensuring the supply of meat, eggs and milk. However, a large amount of breeding waste has not been effectively treated and utilized, which has become a major problem in the environmental governance of rural areas. Grasping the resource utilization of livestock and poultry breeding waste is related to the effective supply of livestock products, the improvement of the ecological environment for production and life of rural residents, and people's livelihood issues. It is also a long-term and arduous systematic project. The state advocates that according to different regions, different livestock species, and different scales, based on fertilizer utilization, economical, efficient and applicable treatment models should be adopted, and fertilizers should be used where fertilizers are appropriate, gas should be used where gas is appropriate, and electricity should be used where electricity is appropriate, so as to realize the local and nearby utilization of manure and sewage. Improving the resource utilization system of livestock and poultry breeding waste and promoting green breeding and farming cycles are one of the key tasks.

[0004] The resource utilization of livestock and poultry manure has become a bottleneck in the development of the animal husbandry industry. It is a hurdle that must be overcome and a difficult problem that must be solved. To develop modern animal husbandry under the new situation, we must solve the problem of adapting the livestock and poultry breeding volume to the environmental capacity, solve the problem of recycling livestock and poultry breeding excrement and land planting, solve the problem of matching livestock and poultry breeding manure utilization facilities with the breeding scale, solve the problem of incorporating manure utilization into the whole process management of the breeding farm, and solve the problem of the incompatibility of capital investment in the resource utilization of livestock and poultry manure with the development of modern animal husbandry. Only by solving these problems of coordinated development of animal husbandry and ecological environment protection can our animal husbandry industry have a foundation for development and room for improvement, can we increase the dependence of society on the animal husbandry industry, and can we achieve the goal of developing modern animal husbandry.

[0005] On the other hand, the problem of excessive application of chemical fertilizers in farmland is serious. Its harm is mainly manifested in the following aspects. First, the soil aggregate structure is destroyed, causing soil compaction, which seriously affects the yield and quality of crops. Second, a large amount of surplus and accumulation of nitrate nitrogen on the soil surface causes soil acidification, which in turn causes an imbalance in soil nutrient ratios and reduces soil fertility. Third, it accelerates the production of greenhouse gases and intensifies the greenhouse effect. Fourth, it causes eutrophication of rivers and lakes and nitrate pollution of groundwater. In addition to the scientific application of chemical fertilizers, the most important solution to the above problems is the application of organic fertilizers and biological fertilizers.
