Abstract
The utility model relates to the technical field of irrigation facilities, in particular to an irrigation pipe suitable for alternate irrigation. The utility model requires to overcome the existing problems of prior art that large labor intensity, high cost, failure-prone and cumbersome to maintenance. To overcome the existing problems of prior art, the technical scheme of the utility model is that : the irrigation pipe suitable for alternate irrigation comprises an irrigation pipe 1 whose pipe wall is provided with outlets 2, and the utility model is characterized in that an isolation layer 3 is arranged in the irrigation pipe 1 along the radial direction, and the pipe walls in the both sides of the isolation layer 3 are arranged with outlets 2.
Description
Affiliated technical field:
The utility model relates to the irrigating facility technical field, is specifically related to a kind of irrigation pipe that is applicable to alternate irrigation.
Background technology:
It is a kind of new water-saving regulating technology that the crop root subregion is carried out alternate irrigation, and it emphasizes that the subregion of crop root zone soil vertical section or horizontal profile keeps dry, and to pour water in other zone moistening, and alternately control section root system drying, part root system are moistening.This method at home and abroad obtains implementing, but in use finds to exist following deficiency: 1, labour intensity is big: tradition alternately furrow irrigation needs artificial modify-water, needs a large amount of labours to drop into; 2, cost height: replace control when realizing alternate irrigation for the interlacing of pipeline irrigation system or pipe, need be equipped with more irrigation pipe and valve, need increase artificial input simultaneously and supervise in the field; 3, easy break-down, maintenance trouble: a large amount of valves is used to control alternate irrigation, the frequency of utilization height, and easy break-down, whole system is to be mutually related simultaneously, not only maintenance bothers, and can influence the irrigation of full wafer crop when the problem of generation.Therefore,, be worthy to be popularized,, really be widely adopted still relatively difficulty because be subjected to not having hardware support kit facility or the high influence of facility price though alternate irrigation can play tangible water-saving and yield-increasing effect in principle.
Summary of the invention:
The utility model will overcome that the labour intensity that prior art exists is big, cost is high, the problem of easy break-down, maintenance trouble.
Overcome the problem that prior art exists, the technical solution of the utility model is: a kind of irrigation pipe that is applicable to alternate irrigation, comprise that tube wall is provided with the irrigation pipe 1 of delivery port 2, its special character is, be disposed radially separation layer 3 in the described irrigation pipe 1, delivery port 2 is arranged on separation layer 3 both sides.
Above-mentioned separation layer 3 is barrier films.The advantage of barrier film is flexible good, can be when a side water-filling, and under the pressure effect of water, barrier film is close to the opposite side tube wall, a side delivery port 2 is blocked, but can the constriction pipeline, influence carrying capacity of pipe.
The material of above-mentioned barrier film is rubber, plastics etc.
Above-mentioned delivery port 2 is provided with pipe and chews 6.Be used for connecing the irrigation hollow billet.
Above-mentioned irrigation pipe 1 can be a flexible pipe.The field applicability of flexible pipe is better.
The water inlet of above-mentioned irrigation pipe 1 is divided into two imports 5.Two imports 5 are connected on the conversion valve, link to each other with water supply installation, can realize fast alternately conversion like this.
The area equalization of the delivery port 2 on the above-mentioned separation layer 3 both sides tube walls.Guarantee the uniformity of irrigation.
Above-mentioned delivery port 2 is staggered uniform with a determining deviation at the both sides tube wall that barrier film separates.Spacing is adjusted with irrigation the different of plant according to the Different irrigation technology.
Aforementioned tube is chewed to connect on 6 and is irrigated hollow billet 4.As required, be placed on the ground of crop root zone both sides (crop root division district alternately controls drip irrigation) or be embedded in certain depth place (crop root division district alternately controls underground drip irrigation or vertical root division district alternately controls drip irrigation) irrigating hollow billet 4, the alternately control in the different roots of crop district is irrigated so that realize.
Compared with prior art, the utility model has the advantages that: with an irrigation pipe or the additional conversion valve of arm, realized than large tracts of land automation alternative water-supply, for alternately controlling irrigation method, the root division district provides a kind of feasible automation installation, for finally reaching water saving, volume increase, saving the labour facility guarantee is provided.
Water-saving result of the present utility model realizes from two aspects, on the one hand be to have guaranteed that from facility the irrigation of crop can adopt alternative irrigation method fully, the different roots of crop district alternately is in does under the wet two states, the root system of plant that is in the local desiccation zone can produce a kind of chemical substance as the water stress signal and be delivered to blade, make blade stomatal opening degree reach an optimal state, do not influence the output of photosynthetic product, and can significantly reduce the transpiration water consumption of crop luxury, saved irrigation water capacity; Be because of having realized the channelization water delivery and poured water, having reduced the evaporation loss in the moisture course of conveying on the other hand.
The utility model can improve the quality of crop, the reason that output also has two aspects, on the one hand root system of plant stand the water stress of a period of time, again after the rehydration, secondary root rolls up, and the root system conduction is higher than the processing of always fully supplying water, therefore, by alternation of wetting and drying, can stimulate root growth, strengthen absorbing capacity and transduction ability, help improving the output of crop; Be to adopt two-chamber indentical tube road to carry out water delivery or water distribution on the other hand, help automation control, can irrigate by timely and appropriate discovery, in time replenish the deficiency of crop water, help improving crop yield and quality alternate irrigation.
The utility model is easy to process, and original irrigation pipe manufacturer all can produce low cost of manufacture.While is manually expended little in use, and fault rate is low, and using for large-area field provides guarantee, is easy to promote the use of.

Embodiment:
To be explained in detail the utility model by specific embodiment below.
Embodiment 1: referring to Fig. 1 and Fig. 2, a kind of irrigation pipe that is applicable to alternate irrigation, comprise that tube wall is provided with the irrigation pipe 1 of delivery port 2, said irrigation pipe 1 is a flexible pipe, be disposed radially separation layer 3 in the irrigation pipe 1, the tube wall of separation layer 3 both sides irrigation pipes 1 is provided with delivery port 2, and delivery port 2 is provided with pipe and chews 6.Said separation layer 3 is barrier films that rubber is made.The spacing of delivery port 2 needs to set as the case may be.Irrigation pipe 1 one ends are provided with water supply installation, other end sealing.
In use, the pipe that is connected with delivery port 2 chews 6 as water filling port, directly discharges water and waters.Under this pouring mode, the irrigation ditch need be excavated in the both sides of crop, on the irrigation pipe 1 pipe of both sides chew 6 respectively with the corresponding setting of crop both sides irrigation canals and ditches.
