Abstract

The present invention relates to a comprehensive water-saving irrigation method for dry farming, which belongs to the field of water conservancy irrigation. The present invention solves the technical problem of the poor reasonable matching of water in dry farming, uses various water collecting methods to accumulate the water, supplies the water and fertilizers to crops by dissolving the fertilizers in a seepage water-saving way, and ensures the high yield of the dry farming.

Description

The comprehensive irrigation saving system of dry farming

The present invention relates to the water conservancy irrigation engineering, especially the dry farming irrigation system.

In the existing dry farming irrigation technique, existing water cellar retaining, cave storage rich water, crock or earthen-ware pipe infiltration irrigation technology, drip irrigation, micro irrigation technology, for example application number is that the underground water-storage reservoir of mentioning in 95107426.1 the application for a patent for invention of building is come storage of water, just belongs to the water cellar retaining.Above technology is all being brought into play retaining, water saving, water conservation with separately characteristics and advantage respectively in the dry farming water conservancy irrigation effect.The weak point that these technology exist is an imperfection, needs the cooperation of conventional river construction, and self does not form a complete and comprehensive system for collecting real estate fees, and can not form a complete irrigation saving system, does not have the fundamentally water shortage problem of system's solution dry farming.Aforesaid application for a patent for invention just belongs to a kind of retaining, water conservation technology, fails further combined with the water-saving irrigation measure.

The purpose of this invention is to provide the comprehensive irrigation saving system of a kind of dry farming complete, standard, will catchment, water storage, joint filling, molten fertilizer etc. are integrated in one, and realize infiltrating irrigation in the back certain hour that discharges water, with the water supply problem of thorough solution dry farming.

The present invention is made of the facility that catchments, water storage facility, joint filling facility, molten fertile facility four parts, wherein: the facility that catchments is made up of some platforms that catchment, the platform that catchments is built according to landform in the massif district, the utilization platform that catchments is assembled rainwater or is borrowed ground will definitely the rainwater interception to filter and compile, or the tiny current in the face of land are compiled; Water storage facility is made up of conduit and water pit, and conduit couples together aforesaid platform and the water pit of catchmenting; Joint filling facility is made up of multistage supply channel and infiltration carrier container, and described multistage supply channel comprises delivery main, arm, hollow billet, and water pit is connected to the infiltration carrier container by multistage supply channel, and the infiltration carrier container is positioned under the crops root; Molten fertile facility is a fertilizer pot that is arranged at delivery main one side, and the two ends of fertilizer pot all are communicated with delivery main.It is characterized in that being implemented in the infiltrating irrigation of back in the certain hour that discharge water by infiltration carrier container 7, size fractionated stone, sand are filled in said infiltration carrier container 7 the inside layerings, it is thick that bottom can be filled out 20cm, diameter is the stone of 6～8cm, it is thick that 10cm can be filled out in the middle part, diameter is the stone of 2～4cm, and the thick pure coarse sand of 10cm can be filled out in the upper strata.

The present invention is by organically combining multiple auxiliary facility, turn parts into the whole, compared with prior art have comprehensive catchment, water storage, joint are irritated, molten fertile effect, self forms the irrigation saving system that complete closure is supporting, realize infiltrating irrigation in the certain hour by infiltration carrier container simple in structure, can fundamentally solve the water supply problem of mountain area dry farming, can also liquid fertilization, improve fertilizer efficiency, soil does not harden; Make as a whole total solution, whole set of installation is improved standard, has construction, use, management is simple and convenient, and the masses easily accept, easy advantage such as popularization.

The present invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is the general structure schematic diagram of native system;

Fig. 2 is that the infiltration carrier container is imbedded the soil profile schematic diagram under the root of the crop;

Fig. 3 is an infiltration carrier container vertical section schematic diagram.

As shown in Figure 1, some platforms 1 of catchmenting are formed the facility that catchments, and the platform 1 that catchments is built according to landform in massif collection rain belt, and its shape is different with landform, and can put down can be recessed, and its position is at higher position, and are beneficial to and catchment, and its material can be used cement, plastics etc.The platform 1 that catchments links to each other with water pit 3 by conduit 2, and conduit 2 is formed water storage facility with water pit 3; The volume of water pit 3 can calculate according to the plan irrigated area, and its building materials are mainly with impervious materials such as cement, and its position is built in can be to the irrigated area gravity flow place that discharges water.Fixedly connected with the pipeline of delivery main 4 in one effluent dewatering orifice 10, water pit 3 bottoms, with the delivery main 4 of water cellar near-end on establish floatless switch valve 11, control is closed water, is discharged water; The material of delivery main can be used steel pipe, plastic tube, pipe of cement etc.; Whole hydraulic pipeline is made up of delivery main 4, arm 5, hollow billet 6 one-level levels according to drip irrigation, slight irrigation pipeline structure; Hydrostate 14 is installed on arm 5, is supplied water evenly to regulate different discrepancy in elevation plot; The general available plastic tube of the material of arm 5, hollow billet 6; Hollow billet 6 passes the nearly bottom that is embedded in the infiltration carrier container 7 under 8 times roots of crops, and in hollow billet 6 usefulness three-way connections 15 sockets of infiltration in the carrier container 7, the water of conveying drops down by of vacating from three-way connection 15; The shell of infiltration carrier container 7 can be made of plastic, size fractionated stone, sand are filled in the inside layering, it is thick that bottom can be filled out 20cm, diameter is the stone of 6～8cm, it is thick that 10cm can be filled out in the middle part, diameter is the stone of 2～4cm, and the thick pure coarse sand of 10cm can be filled out in the upper strata, and this structure makes the infiltration irrigation effect of playing in the back certain hour that discharges water crop 8 roots.Above-mentioned multistage supply channel and infiltration carrier container 7 have been formed joint and have been irritated facility.Side at delivery main 4 also is provided with a fixedly fertilizer pot 9, and two ends of fertilizer pot 9 all use conduit to be communicated with delivery main 4, and are respectively equipped with

P cock valve

12,13 on two end conduits, the controlled water flow switch.

Whole implementation process is that rainwater or fine water stream are assembled by the platform 1 that catchments, and compiles into water tank 3 by conduit 2, opens valve 11 during water, current are by delivery main 4, arm 5, flow into hollow billet 6 again through hydrostate 14, flow into the carrier container 7 that respectively seeps water at last, crop 8 is carried out infiltrating irrigation.After when needing fertilising chemical fertilizer dissolve, open the minor valve 13 of water side in fertilizer pot, liquid fertilizer is flowed into infiltration carrier container 7 with the pipeline current, realization is to the liquid fertilization of crop 8.
