Drip irrigation systems with their own hands : installation instructions

Gardening need timely watering, especially during hot summer months.drip irrigation system - a real salvation for truckers who do not want to spend the lion's share of output to haul garden hose on your site.Drip irrigation - the most rational way to supply plant moisture, does not it allows the root system to dry out, and lack of nutrients, and prevents the formation of a hard crust on the soil surface or the erosion of topsoil.

Drip irrigation systems with their own hands

device drip irrigation

operating principle of drip irrigation is drip feeding water directly to the root plant system.Depending on the equipment used as the moisture can be supplied to the soil surface - by dropping the tape or hose, and a depth of topsoil - using droppers.

By type of water supply system may be gravity or forced.In the first case, water is fed by gravity from a pre-filled tank capacity required in the second - from the water supply or from a pump connected to the well.Drip irrigation systems are designed for pressures up to 2 bar, so have to be fitted with a pressure regulator in a forced system -. reducer.To create the required pressure in the gravity tank system is raised to a height of not less than 1.5-2 meters.

water from a tank or a water supply system is supplied to the watering place on the main pipe having a branch.As the branches are commonly used standard fittings for drip irrigation, for them discussed below.Main pipes are laid along the fence, wall or a greenhouse in the furrow, secured by holders.

system for watering the garden

connected to the branch drip lines extending along rows of plants in the entire length of the bed.As the drip lines, you can use a flexible drip tape with holes or ordinary plastic pipe to which are connected via splitters dropper.The ends of the drip lines is closed with plugs or flushing valves.

avoid clogging the system at the outlet of the tank or in the place of its connection to the water mains installed fine filter and valve valve or gearbox with which regulated the water supply.

design drip irrigation system

For quality drip irrigation should be located at a distance of 30 cm from each other, with topsoil moisture occurs in 1-2 hours.Further watering is undesirable, because it leads to waterlogging and rotting of the root system as well as an overrun of water.During this time, it consumes about 15-30 liters of water per square meter.

To achieve this mode of irrigation, it is necessary to calculate the total length of the system or its individual sectors, as well as the storage capacity of the tank in a gravitational system.The compulsory system can not do without a manual or automatic irrigation control.Manual operation is suitable for gardeners who live in the country: it is enough to open the valve and, while you relax or gather the harvest, the system will moisten the soil to the desired depth.If you spend time in the country is rare, should buy a controller that can be programmed at any time.

volume of the storage tank to calculate quite simple: it is necessary to multiply the irrigated land area in the 20 liters required for humidification of one square meter - this amount of water is enough for a single drip irrigation.

Example of calculating the tank volume:

Greenhouse has dimensions 10h3,5 meters.The area of ​​the greenhouse is 10 · 3.2 = 32 m2.Multiply this value by 30 liters needed for irrigation: 32 · 30 = 960 liters.Thus, for the greenhouse needs a tank volume of 1 cubic meter.

tank must be installed at such a height that ensured a steady pressure in the system.When lifting the tank to a height of 2 meters of the system pressure is 0.2 atm., Which is sufficient for the irrigation of about 50 m2.If the land area is greater when the gravitational water supply method, it is advisable to divide the watering system into sections and supply water to them one by one, or set for each section a separate tank.Solve the problem will also pump that increases pressure - in this case it is necessary to maintain the order of 2 atmospheres.

To ensure sustainable system pressure are important factors such as the diameter of the main pipe and drip lines.Pipe diameters 16 mm passes 600 liters of water per hour, it is enough to irrigate 30 m2 plot.If the land area is bigger, better to choose large diameter pipes: pipe of 25 mm will allow to miss the 1800 liters per hour and pour plot of about 100 square meters, pipe 32 mm has a capacity of about 3 cubic meters, enough to land in 5 acres, and the pipe is 40 mm- 4.2 cubic meters, or 7 acres.

length of each drip line should not exceed 100 meters in any bandwidth of main pipes.Usually drip lines are connected in parallel at a distance equal to the distance between rows of plantings.In the case of watering fruit trees or shrubs have drip line around them at a distance of 0.5-1 m from the trunk.

equipment and fittings

Before starting the installation of drip irrigation systems need to draw the pipes layout plan and calculate the required amount of materials, fasteners and hardware.

For the installation of water supply systems are needed:

• plastic or metal tank the required volume or pump feeding water from the well;
• Flow tap;
• Controller - in the case of the installation of the automated system;
• ball valve;
• Pressure reducer;
• fine filter;

adapter for connection to the irrigation system.

equipment for drip irrigation system

irrigation system includes the following elements:

• Plastic pipe section from 16 to 40 mm for main pipes;
• Trickle or drip feed tube complete with couplers and droppers;
• fittings: taps, tees, minikrany, startkonnektory adapters to connect the drip tape, is a stub.

Mount Technology System

1. Install tank at a height of 1.5-2 meters and connects to the water supply system.The tank crashed into the adapter, which with the help of wind the tape FUM valve tap - it is necessary to regulate the water supply.If water enters the tank from the mains, it can be equipped with a float type shut-off valve is in the drain tank.
   

   Set the tank and connect to the water supply system

2. After the crane set the programmable controller, which regulates the flow of water, depending on the selected program.You can set it on a daily inclusion or watering every few days, and also set the watering time.Once the controller sets the ball valve that allows to block water flow.
   

   Connecting the controller regulates the flow of water

3. put the reduction gear or the pump increases the pressure to regulate the pressure in the feed system.Working pressure - 2.1 atmosphere when leakage increases may be formed at the joints of pipes and drips with decreasing water will flow uniformly.For water purification system equipped with fine filter - this will avoid clogging.
4. K filing system through splitters and adapters connect plastic pipe trunk, cut into pieces, with the distance between the drip tubes.Pipes connected via tees.The last main pipe at the remote end of a crane equipped with a wash - it is useful in case of clogging of the system.
   

   Through adapters connect the main pipe

5. to a tee connected through adapters drip tape or tubes.Drip tape is a flexible hose with perforations through holes made drip irrigation.The tape can be easily cut with a knife, the ends are folded and put on these special clamps, playing the role of a stub.
   

   connect to a tee drip tape

6. Drip pipe - a plastic pipe dimeter usually it does not exceed 16 mm.The top tube at a distance of 30-60 cm make holes for the hub diameter of 3 mm.They inserted rubber seals and splitters, which can have from 2 to 4 branches.The branch is inserted hoses droppers - plastic tubes with holes.Droppers are stuck in the ground near the plants.

7. are testing the system and determine the necessary pressure, which is controlled brushless gear or valve on the tank.

installation of drip irrigation systems with their own hands is not difficult, when properly calculating drip irrigation can reduce the complexity of gardening work and raise a crop in 1,5-2 times.In winter, the system can be easily disassembled: removed the tube and dropper with water tank is drained, cleaned regulating equipment.If necessary, the system can be expanded or reschedule.Its application is not limited to a garden plot, it can be successfully used on beds, balconies, lawns and in the greenhouse.
