Alkaline land improving upper farming lower fishing zoology breeding method

Abstract

The invention provides an improved farming-above and fishing-below ecology breeding method in the saline-alkali land. A sunlight greenhouse (1), a fish pond (4), a livestock breeding house (2), a residence house (5), and a methane pond (3) are arranged concentratively. The dejection can be used for feeding the fish or be put into the methane pond, the marshy liquid and the marshy dregs can be used for fertilizing the field or fatting the fish, and the methane can be used for lighting or cooking. Through matching the agricultural integrated producing technologies, the invention can make up the deficiency of the own condition of the earthiness, and can ensure that the saline-alkali wasteland tends towards the virtuous ecological cycle after the project is put in practice. The forage grass planted in the cropland can be used to feed the livestock, the dejection of the livestock can be used to feed the fish or produce methane, the silt and the marshy liquid of the fishing pond can be used to fertilize the cropland. The greenhouse and the fishing pond can produce the pollution-free and green food, which can improve yield benefit of the soil maximally. The peasants in the area can be led to be rich and to live a relatively comfortable life.

Description

Technical field: [0001] The invention relates to an agricultural planting method, in particular to an ecological planting and breeding method for improving upper agriculture and lower fishing in saline-alkali land. Background technique: [0002] The Chinese patent "system engineering for the comprehensive development and utilization of ecological breeding pigs and earthworms" (CN02132497.2) discloses a kind of ecological agriculture technology, especially the system engineering for the comprehensive development and utilization of ecological breeding pigs and earthworms. It raises pigs in a pig house in a plastic sunlight greenhouse. The feed is mainly grain, combined with organic compound feed made of earthworm powder. Biogas is fermented and extracted for bottling; earthworms are fed on the other side of the greenhouse, and biogas residues are used as feed for earthworms; biogas slurry and earthworm manure can be made into high-quality organic compound fertilizers for the p...

Problems solved by technology

[0004] The technical solutions of the above two patent applications do not address the improvement of saline-alkali land, and do not organically combine soilless cultivation technology and ecological breeding technology, and both have their own defects and limitations.
