Intensive circular agricultural system combining facility agriculture and ecological farming

Abstract

The invention relates to an intensive circular agricultural system combining facility agriculture and ecological farming. The intensive circular agricultural system includes a standardized ecologicalcattle farm, a vegetable greenhouse of facility agriculture and a biogas production plant; waste produced by the standardized ecological cattle farm and the vegetable greenhouse of facility agriculture is converted into biogas through biogas production equipment, biogas vehicles are used as the main means of material transportation, and biogas slurry and biogas residue are used as a fertilizer forfacility agriculture. The waste generated by the planting industry and farming industry is subjected to resource utilization, the use efficiency of the waste is improved, the production cost is reduced, and the closed flowing of materials can be realized.

Description

technical field [0001] The invention relates to an agricultural ecological circulation system, in particular to an intensive circulation agricultural system combining facility agriculture and ecological breeding. Background technique [0002] Traditional agriculture is mainly based on extensive management, with small production scale, relatively backward management and production technology, poor ability to resist natural disasters, low efficiency of agricultural ecosystems, low production efficiency, and serious waste of resources. At the same time, some farmers are overly pursuing short-term interests and using a large amount of chemical fertilizers and pesticides, which not only leads to serious food safety problems, but also poses a great threat to the natural environment.

AI Technical Summary

Problems solved by technology

[0002] Traditional agriculture is mainly based on extensive management, with small production scale, relatively backward management and production technology, poor ability to resist natural disasters, low efficiency of agricultural ecosystem, low production efficiency, and serious waste of resources.

At the same time, some farmers are overly pursuing short-term interests and using a large amount of chemical fertilizers and pesticides, which not only leads to serious food safety problems, but also poses a great threat to the natural environment.

[0003] The existing forms of circular agriculture mainly include: the combination of greenhouse planting and animal husbandry, and the excrement produced in the process of animal husbandry to provide nutrients for greenhouse planting, but this mode can only be used on a small scale, and there is still a lot of excrement Cannot be used; the combination of rice fields and aquaculture, rice fields provide food for aquatic products, and the excrement of aquatic products is used as fertilizer for rice fields. This model has high requirements on the regional climate and cannot be widely promoted

[0004] There is following shortcoming in prior art: (1) the use efficiency of excreta is low

The existing technology uses the excrement produced by the breeding industry directly as fertilizer, and does not use the excrement as a resource, resulting in a waste of resources; at the same time, the untreated excrement is also conducive to the absorption of plants, which reduces the use efficiency of the excrement

(2) High production cost

In the existing technology, the material cycle between the breeding industry and the planting industry consumes a lot of energy for transportation, which increases the cost of the entire agricultural cycle process. This problem makes it difficult for these technologies to be truly applied in practice.

(3) It is difficult to realize the closed flow of substances

The existing technology only focuses on the reuse of excreta in the agricultural production process, but does not pay attention to the matching of the scale of the planting industry with the breeding industry, which often causes the waste generated by the breeding industry to not be completely consumed, the efficiency of material circulation is low, and it is difficult to fully realize the material recycling. fully closed
