Grain production and water environment protection circulation system for modern agriculture

Abstract

The invention discloses a grain production and water environment protection circulation system for modern agriculture and belongs to the technical field of agriculture and environment. A large livestock breeding base and a large slaughter deep processing base convey livestock manure and offal into a large industrial biogas center; the large industrial biogas center is combined with an urban waste processing center to send biogas slurry and biogas residue to a biogas slurry processing center and a biogas residue processing center, and then converts the biogas slurry and the biogas residue and sends the biogas slurry and the biogas residue to an organic fertilizer production base; produced organic fertilizers are sent into a modern pollution-free agricultural production base; and fuel and raw materials which are processed through the large industrial biogas center are sent to a biodiesel raw material center and a biogas and ethanol fuel raw material center. The agricultural circulation can be developed towards targets of two zero growths which are agricultural resource and agricultural energy consumption zero growth and agroecological environment degradation rate zero growth zero growth, and thus an agricultural development model of efficient sustainable use of the agricultural resources and virtuous circle of the ecological environment is adopted positively.

Description

technical field [0001] The invention relates to the technical fields of agriculture and environment, in particular to a circulation system for high grain yield and water environment protection in modern agriculture. Background technique: [0002] According to reports, my country's agricultural development is currently facing many problems and difficulties, mainly in the following aspects: [0003] One is the shortage of agricultural resources. The most important is the shortage of water resources and arable land resources. my country is a typical water-poor country, with per capita fresh water resources of only 2,627 cubic meters and an annual agricultural water shortage of 30 billion cubic meters, ranking above 100 in the world. The per capita arable land is also very limited, and the per capita arable land in some areas is close to or lower than the danger point set by the United Nations. While agricultural water and soil resources are insufficient, agricultural droug...

AI Technical Summary

Problems solved by technology

[0004] Second, the resource utilization efficiency is low

There are about 500 million tons of straw resources in the country every year, and most of them are used as fuel, the proportion of development and utilization is low, and it pollutes the environment

[0005] Third, agricultural non-point source pollution is serious

A large number of crop straws are burned in the planting industry, which has caused serious pollution to the atmospheric environment.

A large amount of chemical fertilizers and pesticides are used in agricultural production, and the use of chemical fertilizers accounts for 30% of the world. The low utilization rate of chemical fertilizers also causes serious pollution to the water environment

[0006] Fourth, the damage to agricultural ecology and the environment is serious

[0007] Fifth, the residues of agricultural products are serious and the quality has declined

[0008] Sixth, the potential of agricultural production has not been effectively utilized

[0009] In addition, my country's agriculture still has low quality agricultural human resources, population pressure restricts agricultural development; the contribution rate of agricultural scientific and technological progress is low; agricultural production is small in scale and low in efficiency, and agricultural products do not have a competitive advantage; problems and constraints

[0010] These problems and difficulties faced by agricultural development show that the development of traditional agriculture is facing severe challenges
