Abstract
The invention relates to a seedbed irrigation system which comprises a water supply network (1), a branch pipe (4), a seedbed irrigation blanket (5), a water draining network (7) and drip irrigation bands (13). The water supply network (1), the branch pipe (4), the drip irrigation bands (13) and the water draining network (7) are sequentially connected through pipes. The branch pipe (4) is arranged at one end of the seedbed irrigation blanket (5), and the multiple drip irrigation bands (13) communicated with the branch pipe (4) are arranged in parallel and penetrate through a non-woven fabric core layer (10) of the seedbed irrigation blanket (5); the seedbed irrigation blanket (5) is composed of a non-woven fabric face layer (9), the non-woven fabric core layer (10), a non-woven fabric bottom layer (11) and an impervious layer (17) from top to bottom. The seedbed irrigation system has the advantage of being suitable for the facility agriculture seedbed cultivation mode; compared with tube-well irrigation, the seedbed irrigation system has the advantages that labor is saved, water is saved, and non-point source pollution is reduced; compared with tide type irrigation, the seedbed irrigation system has the advantages that one-time investment is less, the seedbed transformation cost is low, and irrigation is even; the management level of agricultural water in China can be remarkably improved.
Description
Technical field
The invention belongs to water conservancy irrigation technical field, specifically a kind of seedbed irrigation system.
Background technology
China is water resource relative shortage, and agricultural water accounts for 60% of whole society's total water, and water efficiency of irrigation is only 0.5, also has larger gap compared with the level of the water efficiency of irrigation 0.75-0.85 of developed country.Industrialized agriculture floriculture, grow seedlings and generally on seedbed, carry out, bed planting mainly adopts cave dish and potted plant mode, because crop-planting spacing is grown and constantly changes breeding time with canopy, adopt traditional drip irrigation method for designing, be difficult to meet the production reality that crop spacing constantly changes.
At present, general pipe filling mode, drip irrigation or the tidal irrigation aspect of adopting irrigated in seedbed, and pipe filling mode is that workman takes irrigator to irrigate by basin, need a large amount of artificial, efficiency is lower, water efficiency of irrigation is lower; Bed planting adopts the difficult point of drip irrigation maximum to be that drip irrigation system dripper spacing is fixed and planting pot spacing constantly exists contradiction between variation.And that tidal irrigation is applied is abroad more, main by building waterproof seedbed, supply water and make seedbed reach the way of supplying water of certain depth of immersion from bottom, tidal irrigation is stricter to water irrigating depth control accuracy, and existing silk screen seedbed will transform waterproof seedbed as, the horizontal error in seedbed need to be controlled within the specific limits simultaneously, otherwise, depth of immersion difference can affect plant growth uniformity, and investment and management expectancy are all higher.Therefore, research and develop a kind of reduced investment, uniformity of irrigation water appilcation is high, irrigation water availability is high seedbed irrigation system is extremely urgent.
Summary of the invention
The object of the invention is the defect existing for prior art, a kind of seedbed irrigation system that improves uniformity of irrigation water appilcation and water efficiency of irrigation, reduction operation and maintenance cost is provided.
A kind of seedbed irrigation system, comprise water supply network 1, arm 4, seedbed pour water blanket 5, drainage pipeline networks 7 and irrigate band 13, described water supply network 1, arm 4, irrigate band 13, drainage pipeline networks 7 are connected by pipeline successively, arm 4 is arranged on blanket 5 one end of pouring water, seedbed, and the multiple irrigate bands 13 that are connected with arm 4 be arranged in parallel and run through the pour water nonwoven sandwich layer 10 of blanket 5 of seedbed; The described seedbed blanket 5 of pouring water is made up of nonwoven surface layer 9, nonwoven sandwich layer 10, bottom layer of non-woven fabrics 11 and impermeable stratum 12 from top to bottom.
On pipeline between described water supply network 1 and arm 4, be also provided with filter 2 and control valve 3.
Described control valve 3 is wireless Directional Control Valve, can long-rangely accept switching signal, reduces control system wiring investment, is convenient to safeguard.
On pipeline between described irrigate band 13 and drainage pipeline networks 7, be also provided with draining valve 6.
Described impermeable stratum 12 is high-density polyethylene layer.
The advantage of seedbed of the present invention irrigation system is: be suitable for industrialized agriculture bed planting mode, compared with filling with, have the advantages such as saving of labor, water saving, minimizing pollution of area source with pipe; Compared with tidal irrigation, the advantage such as have that one-time investment is few, seedbed improvement expenses is low, pour water evenly, can significantly improve China's agricultural water managerial skills.
The present invention significantly improves water efficiency of irrigation, remote controlled and do not rely on manual operations, and on existing irrigation installation basis, improvement cost is low, easy popularization simple to operate; Can significantly improve the uniformity of irrigation water appilcation in seedbed, there is good application prospect.
