Ecological circulating beef cattle culturing farm building method and system

Abstract

The invention discloses an ecological circulating beef cattle culturing farm building method and a system. The building method comprises steps of (A) selecting a site for a beef cattle culturing farm, (B) building cattle houses, (C) building a fertilizer pool, (D) arranging liquid fertilizer discharging pipes, wherein in the (C) step, the fertilizer pool has two layers: the lower layer is a liquid fertilizer pool and the upper layer is a solid fertilizer pool; and in the (D) step, the liquid fertilizer pipes are orderly installed on the liquid fertilizer pool wall. A water source is connected with a food tank in the cattle house via a water pipe; the solid fertilizer pool is connected with the liquid fertilizer pool; bovine urine discharging trenches in the cattle house are connected with the lower layer liquid fertilizer pool via plastic pipes; the liquid fertilizer pool is connected with an agricultural land orderly via a liquid fertilizer discharging pipe, a valve, a filter device, an air valve, a pressure adjusting valve, a master pipe, branch pipes, a valve, flow meters and plastic drip-irrigating pipes. The ecological circulating beef cattle culturing farm building system is simply structured and can be conveniently used; beef cattle growth can be facilitated; and the ecological circulating beef cattle culturing farm building method and system are suitable for application in low mountains and hilly areas.

Description

Technical field [0001] The invention relates to the technical field of agricultural breeding, and more specifically to a method for constructing an ecological circulating beef cattle breeding farm. At the same time, it also relates to a construction system of an ecological recycling beef cattle breeding farm, which is suitable for the development of ecological high-value recycling agriculture in areas such as subtropical low mountains or hills. Background technique [0002] With the continuous development of the livestock and poultry intensive breeding industry, the scale of breeding continues to expand, unreasonable farm construction and extensive farm management methods have caused the environmental pollution problem of breeding wastes to become increasingly serious. Not only the random discharge of farming wastewater has caused the pollution of surface water and groundwater by organic matter, nitrogen and phosphorus, leading to eutrophication of the water body, but also the pu...

Problems solved by technology

However, the device has high cost, complex structure, difficult maintenance, and is difficult to be widely used in production.

CN103329849A (2013) announced a method for constructing a circular agricultural system for grass, beef, cattle and vegetables in subtropical hilly areas. The patent includes the construction of a cowshed and a fertilizer pool. The cowshed uses a movable board room to build a solid fertilizer pool and a liquid fertilizer respectively. The shortcomings of the pool are that the construction cost is relatively high and the floor area is large. At the same time, the exit of the defecation ditch is very deep when the cowshed is long, which is inconvenient to wash and clean. The slope of the cowshed floor is small, which is not conducive to the excretion of cow urine.

This method is not only complicated, but also requires a large amount of organic matter such as straw powder or rice bran, and is not suitable for the treatment of liquid waste from cow urine

At present, there are still many farms that put breeding waste into biogas digesters to generate biogas. The problem is that biogas production obviously cannot be fermented in winter, and the waste after biogas generation also needs to be treated twice, and the solid-liquid mixing and separation after biogas fermentation It is also very difficult to handle. This method also has problems such as complicated process, high cost, and difficult operation. It is difficult to promote
