High-efficiency agricultural ecological cycle system with zero emission and zero pollution

Abstract

The invention relates to an efficient agricultural ecological cycle system with zero release and zero pollution. The system comprises a farmland production system, a pig raising system, a nursery stock and vegetable planting system and a special specie cultivation system, wherein the farmland production system comprises a plurality of lands for producing raw materials such as corns, barley, wheat and the like; the pig raising system comprises pig farms, normal-temperature anaerobic biogas digesters, intermediate-temperature tank type biogas digesters and heating boilers; the nursery stock and vegetable planting system comprises nursery stock gardens, vegetable and flower gardens, lotus root ponds and fruit tree forest lands; and the special specie cultivation system comprises fishponds and undergrowth cage-free farms. According to the agricultural ecological cycle system, the lands, the livestock farms, the fishponds, the fruit tree forest lands, the vegetable gardens and the like are combined organically, waste produced in each process is treated to be the raw material for a next process, so that the whole production process begins from the lands and returns to the lands finally, zero release and zero pollution are realized, and the environment is free of pollution.

Description

technical field [0001] The invention relates to an agricultural ecological circulation system, in particular to a zero-emission, zero-pollution, high-efficiency agricultural ecological circulation system. Background technique [0002] Agriculture is the primary industry on which human beings depend for survival. As far as China is concerned, if agriculture is abundant, the foundation will be strong; if farmers are rich, the country will prosper; if agriculture is stable, the society will be safe. Therefore, agriculture has always been highly valued by the country. Especially since the reform and opening up, my country's agriculture has made great progress. It uses less than a tenth of the world's arable land to feed one-fifth of the world's population. However, compared with the world's advanced agriculture, my country's current agriculture is characterized by extensive, scattered, backward production and management, low degree of modernization, serious waste of resources, h...
