Construction system for ecological circulating beef cattle breeding farm

Abstract

The invention discloses a construction system for an ecological circulating beef cattle breeding farm. A water source is connected with a food trough in a cattle house via a water pipe; a fertilizer pool is divided into two layers; the upper layer is a solid fertilizer pool and the lower layer is a liquid fertilizer pool; the solid fertilizer pool is connected with the liquid fertilizer pool; a bovine urine drainage trench of the cattle house is connected with the lower layer liquid fertilizer pool of the fertilizer pool via a plastic pipe; the liquid fertilizer pool is orderly connected with the agricultural land via a liquid fertilizer drainage pipe, a valve, a filter device, an air valve, a pressure adjusting valve, a main pipe, a branch pipe, a valve, a flow meter and a plastic drip irrigation pipe; two sides of a corridor are connected with cattle beds; the external side of each cattle bed is connected with a bovine urine drainage trench; a food trough is placed on the cattle bed on two sides of the corridor; an open yard is formed in the top of the liquid fertilizer pool; holes are formed in a separation wall in the liquid fertilizer pool; a sewage drainage pipe is placed on the bottom of the liquid fertilizer pool; and the liquid fertilizer drainage pipe is away from the bottom of the liquid fertilizer pool. The construction system for the ecological circulating beef cattle breeding farm is simply structured, convenient to use, requires low cost and has wide practical range; fecal sewage can be made into fertilizers to be utilized to crops; and no pollution is caused to the environment.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, and more specifically relates to a construction system for an ecological cycle beef cattle farm, which is suitable for application in the development of ecological high-value cycle agriculture in 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 pollution of the environment caused by breeding waste to become increasingly serious. Not only is the aquaculture wastewater discharged randomly, causing organic matter, nitrogen, phosphorus, etc. to pollute surface water and groundwater, leading to eutrophication of the water body, but also the surrounding areas of the farms have pungent and foul odors, and the air pollution is also very serious. The environmen...

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
