The planning and design of drip irrigation system consists of the following parts:

(1) the collection and collation of basic information

(2) selection of drip irrigation system

(3) planning and layout of the field pipe system

(4) system and work system design of irrigation system

(5) hydraulic calculation and structural design of pipe

(6) pump station design

(7) engineering budget

(8) economic benefit analysis

Drip irrigation is a kind of precision irrigation methods, use low-pressure pipeline system, water directly transported to the field, again after installation in the capillary drop head, orifice or drip irrigation belt emitter, will be a drop of water dripping evenly and slowly drop into the crop root zone soil near, root crops in the most developed area soil often maintain a suitable humidity, soil water, fertilizer, gas, heat, microbial activity, always in a good condition, to create favorable conditions for crop yield. It is the most effective method of water saving irrigation in arid area at present, and its application in water drip irrigation

Utilization rate of 95%. Irrigation drip irrigation was higher at the same time can be combined with the effect of water saving and increasing yield, fertilization, fertilizer more than doubled. Can be applied to fruit trees, vegetables, economic crops and greenhouse irrigation, in the arid areas can also be used for field crops irrigation. The shortage is that it is easy to fouling and clogging, and therefore, to deal with the water source of strict filtration. Domestic equipment has been the basic clearance, the conditions of the region should actively develop drip irrigation.

Drip irrigation belt is divided into patch type drip irrigation belt and labyrinth type drip belt.

Labyrinth characteristics

1, labyrinth channel and drop hole a vacuum overall hot press molding, good adhesion, high manufacturing precision.

2, the turbulent regime over water, anti clogging ability.

3, the labyrinth channel design, the water outlet is even, can reach 85% above, the laying rate is 80m.

4, light weight, easy to install and manage, low labor cost.

Patch type features

1, inside the drop head comes with filter window, anti blocking performance is good.

2, the design of turbulent flow channel. Irrigation uniformity.

3, drop head, pipe integrity is strong,

4, drop head distance between flexible adjustment, wide range of application

5, low price.

Applicable conditions

1, for the greenhouse, greenhouse crops, reduce the disease and insect pests, save the fertilizer and pesticides, improve economic efficiency.

2, for orchard irrigation, can effectively improve the yield, improve fruit quality, effective control of weed growth.

3, suitable for cotton, Chinese herbal medicine, watermelon, field vegetables and other field crops, improve the mechanization of planting intensity.

4, drip irrigation belt around the long curved laying, convenient operation.

Install

1, according to the design document requirements, comprehensive check equipment type, specification, quantity and quality, strictly prohibited the use of substandard products. To install the equipment should be kept clean, plastic pipe shall not fall behind, dragging and exposure.

2, according to the design requirements and the flow of the installation of water meter, valve, filter. Between the filter and the branch pipe are connected by straight threaded.

3. Thread fitting for the installation of drip irrigation system.

When the tape is required, through the lock mother should be tightened.

4, the first branch in the bypass before the installation of special punch punch. Punch, punch not tilt, drill pipe depth should be no more than 1/2 diameter; and then pressed into the bypass pipe.

5, slightly larger than the length of the plant line cutting pipe (belt), drip irrigation pipe (belt) along the plant layout, and then one end and the bypass phase.

6, drip irrigation pipe (belt) installed, open the valve flush pipe and closed the valve; the drip irrigation pipe (belt) plug installed in the drip irrigation pipe (belt) at the end of the; the branch pipe plugging head is installed at the end of the branch pipe.

7, the installation sequence of the whole irrigation system: valve, a filter, a straight, branch pipe, drilling, bypass, drip irrigation tube (band), flushing pipe, plug.
