Description

Pasture double-tower system capable of recycling liquid

Technical Field

The invention belongs to the technical field of pasture production devices, and particularly relates to a pasture double-tower system capable of recycling liquid.

Background

At present, the high-quality feed in China has the problems of high cost, high dependence on foreign germplasm, land resource limitation on production and the like, so that the development of high-quality animal husbandry is hindered. Particularly, the problems of shortage of land resources, less suitable pasture planting areas, limitation of climate factors and the like exist in partial areas, so that huge gaps exist in high-quality feed stably provided all year round. Is one of the main challenges of developing high-quality animal husbandry with stable production all the year around in China.

Water culture pasture is used as a special cultivation mode for pasture cultivation, and the earliest use record can be traced to 1800 years. At the time, the seeds were used mainly by european farm farmers to produce fresh germinating pasture and as feed for farm animals (cows being the main) in winter to maintain winter production activities (milk production) and to increase winter production. In recent years, in countries such as the middle east, africa and asia, the production of fresh feed cannot be sufficiently supplied to the needs of animal husbandry, especially to the supply of high-quality feed, due to the influence of population growth pressure, feed supply pressure and land resource pressure.

One of the major challenges in current pasture production is that pasture yield is difficult to increase. The main reason is that the land resource pressure is increasing day by day. The increase in the production of cereals, oil crops and legumes has led to a tremendous pressure on the land resources for pasture production. In order to meet the ever-increasing demand for fresh, high-quality pasture, one of the alternatives is intensive production-hydroponic pasture. The water culture pasture cultivation uses large space or production equipment with an environment control function, obtains higher water culture pasture yield in a short time through a complex automatic transmission and control system, ensures that pasture products have high nutritive value, and is beneficial to the health and growth of livestock animals. The water planting pasture system has high utilization efficiency of water resources and land resources, highly controllable environmental conditions and a harmless production process without participation of chemical articles such as pesticides, herbicides and the like. These advantages make hydroponic pasture systems well suited for harsh climatic environments such as deserts, soil-poor areas or traditional agricultural areas where land costs are high. Particularly in semiarid, arid and arid regions or regions partially suffering from long-term water shortage or in which irrigation infrastructure does not exist, the production mode of the water culture pasture can greatly improve the 'difficult' problem of the feed for local livestock raising. By hydroponics we can produce pasture grasses including maize, barley, oats, sorghum, rye, alfalfa and triticale. In conclusion, the water culture pasture can maintain a production mode of continuous production all the year around, high-quality fresh pasture production and high land resource utilization efficiency. The feed can support regional animal farms to complete self-sufficiency of partial high-quality feeds, and has higher practical significance and economic value.

In order to solve the above problem, upon search, chinese patent CN201880004922.6 discloses a system for providing an in-line growth cabin, the growth cabin comprising: a housing defining an environmental enclosure volume, a track forming a plurality of helices defining a path, and a cart receiving plants and traversing the track; the system includes a sensor for determining plant yield, a plurality of environmental influencers that alter an environment of an environmental enclosure volume to alter plant yield, and a growth pod computing device that stores a growth recipe that, when executed by a processor of the growth pod computing device, actuates at least one of the plurality of environmental influencers. Further, chinese patent CN202110644632.1 discloses a plant hydroponics production system, which includes a transmission part and a production tower main body with an outlet and an inlet, wherein a bearing part spirally extending along a vertical direction is present in the production tower main body, and the bearing part forms a multi-layer structure on the production tower main body; the conveying part is positioned on the bearing part and movably arranged along the bearing part and is used for conveying the culture trays, and the speed of the conveying part is controlled to enable the culture trays in different layers of the production tower main body to be in different growth stages; and environmental parameters such as water, carbon dioxide and the like can be accurately regulated and controlled according to different growth stages.

In the above disclosed structure, at least 1 opposite point is taken on each layer of the rotating tower as a spray irrigation point, and each planting disk 400 enjoys 1 irrigation opportunity on each layer when the tower body is rotated in operation. However, the nutrient solution sprayed into the planting tray flows back to the lower recess along the planting tray, and then pollutes the environment along the tower body flow everywhere.
