Description
Technical field
The present invention relates to the technical field of slight irrigation, specifically a kind of laying method of drip irrigation below the surface pipe.
Background technology
Drip irrigation below the surface is a kind of new drop being widely popularized in recent years in the country such as the U.S., Australia and Israel
Irrigation technology, i.e. drip irrigation pipe are laid on below arable layer, and the liquid manure required for crops is directly irrigated to the drip irrigation to crop root
Mode.This method is suitable for the plantation of the crop field drilling crop such as cotton, corn, wheat, tomato, potato, has water saving, increases
Production, saving of labor, save branch, carry the advantages that effect.
After cropping season, if soil moisture content does not reach the requirement of crop emergence, drip irrigation below the surface system is needed to use to enter
Row irrigates moisturizing, as shown in figure 1, traditional drip irrigation below the surface pipe 1 is all laid on the same depth of arable layer, general buried depth is
30-40cm, drip irrigation irrigating water quota general control is within 20m3/ mus.Drip initial stage, be initially formed from water dropper to surrounding expansion and
The wetting body 2 that water content gradually decreases；Being incremented by over time, wetting body edge is gradually reduced with surrounding soil hydraulic gradient,
Soil matrix gesture reduces, and gravitational potential occupies leading position, and moisture is gradually presented variable speed migration, moisture longitudinal diffusion speed by
Gradually it is more than lateral velocity, the wetting body of this period is oval；It is gradual with the further passage of time, the wetting body of adjacent water dropper
Cross, ultimately form dumbbell shaped wetting body 2, and wetting body does not cover the position of Seedling root 2.
Under conditions of identical irrigating water quota, drip irrigation below the surface tube pitch is smaller, wetted front is bigger, the area that crosses is bigger, shape
Into wettable layer it is thicker, this is favourable to crops seedling stage moisturizing, but also increases the dosage of drip irrigation pipe simultaneously, causes cost to increase
Add.And under the identical spacing of drip irrigation below the surface pipe, irrigating water quota is bigger, wetted front indulges the moistening that bigger, adjacent water dropper is spread on face
Peak crosses more abundant, and water dropper above moisture distribution is more uniform, and this is also beneficial to the moisturizing of crops seedling stage, but can increase irrigation
Water, reduce the effective rate of utilization of irrigation water.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of laying method of drip irrigation below the surface pipe.
The present invention is adopted the technical scheme that to solve technical problem present in known technology:
The laying method of the drip irrigation below the surface pipe of the present invention, including shallow embedding laying and standard laying；When drip irrigation pipe is laid,
The standard that drip irrigation pipe is carried out along the center line of the pre- plant position of adjacent rows first is laid, and after the completion of standard laying, keeps laying
Spacing is constant, along pre- plant position carry out shallow embedding laying, shallow embedding laying after the completion of by each drip irrigation pipe respectively with water supply branch pipe and
Drainpipe is connected.
The present invention can also use following technical measures：
The buried depth of drip irrigation pipe is 15-20 centimetres in described shallow embedding laying.
The buried depth of drip irrigation pipe is 30-35 centimetres in described standard laying.
The present invention has the advantages and positive effects of:
In the laying method of the drip irrigation below the surface pipe of the present invention, while include the drip irrigation pipe laying of two kinds of different buried depths,
After the completion of drip irrigation, drip irrigation wetting body is set to increase to crops seedling stage root system, moisture distribution is uniform in planned moist layer in soil；It is shallow
Crops seedling stage moisturizing requirement can be ensured under conditions of earth's surface fine-spraying belt is not laid by burying laying, and standard laying disclosure satisfy that crop
Each breeding time needs water requirement after seedling stage.Under conditions of the dosage of drip irrigation pipe and duty is not increased, make drip irrigation wetting body
Crops seedling stage root system is expanded to, meets the irrigation moisturizing demand of crops seedling stage.
Brief description of the drawings
Fig. 1 is the schematic diagram of the laying pattern of drip irrigation pipe in the prior art；
Fig. 2 is the drip irrigation schematic diagram formed by the laying method of the drip irrigation below the surface pipe of the present invention.
Embodiment
Technical scheme is specifically described below in conjunction with drawings and examples.
The laying method of the drip irrigation below the surface pipe of the present invention, including shallow embedding laying and standard laying；When drip irrigation pipe is laid,
The standard that drip irrigation pipe 1 is carried out along the center line of the pre- plant position of adjacent rows first is laid, and after the completion of standard laying, keeps laying
Spacing is constant, along pre- plant position carry out shallow embedding laying, shallow embedding laying after the completion of by each drip irrigation pipe respectively with water supply branch pipe and
Drainpipe is connected.
Drip irrigation pipe situation after the completion of laying lays completion as shown in Fig. 2 the drip irrigation pipe for being distributed in crop both sides is standard,
And middle drip irrigation pipe is laid by shallow embedding and completed.Wherein the buried depth of drip irrigation pipe is 15-20 centimetres in shallow embedding laying；In standard laying
The buried depth of drip irrigation pipe is 30-35 centimetres.
Drip irrigation pipe laying is carried out by the laying method of the drip irrigation below the surface pipe of the present invention and forms drip irrigation pipe system, once
After the completion of drip irrigation, drip irrigation wetting body 2 is set to increase to crops seedling stage root system 3, moisture distribution is uniform in soil moist layer；Shallow embedding is laid
After can ensureing that crops seedling stage moisturizing requirement, standard laying disclosure satisfy that crops seedling stage under conditions of earth's surface fine-spraying belt is not laid
