Drip irrigation is a method of irrigation, which is very important for the growth and development of plants. The drip irrigation tape is a key part of the drip irrigation system. The selection and installation of the drip irrigation tape directly affects the effect and operation of the entire drip irrigation system. Let's take a closer look at the selection and installation of the drip irrigation tape equipment.

Drip irrigation tape selection

1. Material selection

Drip irrigation tapes are generally made of plastic, rubber and composite materials. At present, the common material of drip irrigation tapes on the market is polyethylene, which has good corrosion resistance, aging resistance and durability. At the same time, polyethylene drip irrigation tapes can choose different colors of drip holes according to fertilization requirements, which is conducive to controlling the amount of fertilizer.

2. Pressure requirements

Different types of drip irrigation tapes have different pressure requirements. When choosing a drip irrigation tape, the pressure of irrigation water and the water delivery capacity of the pipe network should be considered, and try to avoid using drip irrigation tapes that do not meet the requirements.

3. Drip hole spacing and flow rate

The drip hole spacing and flow rate of the drip irrigation tape will directly affect the effect and accuracy of irrigation. The shorter the drip hole spacing and the smaller the flow rate, the more uniform the irrigation can be achieved. Different types of crops have different requirements for irrigation flow and drip hole spacing, so you should choose according to the actual situation.

4. Temperature resistance

Under the temperature conditions of high temperature in summer and low temperature in winter, the temperature resistance of the drip irrigation tape is also a factor to be considered, otherwise the drip irrigation tape is prone to aging and cracking, affecting the irrigation effect.

Installation of drip irrigation tape

1. Determine the route

Before installing the drip irrigation tape, you need to determine the irrigation route and irrigation range first. Due to the unidirectional water flow of the drip irrigation tape, its installation direction must be perpendicular to the route.

2. Laying the drip irrigation tape

There are two ways to lay the drip irrigation tape. One is to lay it directly on the ground, and the other is to bury the drip irrigation tape in the soil. The latter method is commonly used. Burying the drip irrigation tape in the soil 10-20 cm deep where the root system is located can not only reduce the evaporation loss of water, but also effectively protect the drip irrigation tape from damage.

3. Fix the drip irrigation tape

After the drip irrigation tape is laid, it needs to be fixed in time to prevent the drip irrigation tape from moving or falling off due to external forces such as wind and rain. Common fixing methods include iron clips and plastic clips.

4. Connecting accessories

Accessories for connecting drip irrigation tapes include steering heads, straight heads, water stops, etc. When connecting and adjusting various accessories, be sure to ensure that the connection is firm to avoid water pressure from damaging the connection, and check whether the connection is leaking.

In short, the selection and installation of drip irrigation tape equipment is an important part of determining the effect of the drip irrigation system. Therefore, we should choose high-quality drip irrigation tapes and install them according to standard operations to ensure the normal operation of the drip irrigation system and achieve the best irrigation effect.
