With the development of the economy and the deepening of the concept of saving the environment, water-saving technologies in agricultural irrigation are being promoted, resulting in an increasing demand for drip tape. The market is expanding rapidly, and there are more and more manufacturers producing products for this industry, which has caused the problem of uneven product quality.
If low-quality drip tape is chosen, it may cause several hazards. One is that it is prone to aging and cracking during use, which shortens its service life and makes installation and maintenance time-consuming and laborious. Another is that uneven irrigation and fertilization will lead to uneven crop growth, crop yield reduction, and impact on earnings.
Drip tape is used to irrigate crops locally by passing water through a plastic pipeline to the root of the plant through small holes or drip heads with a diameter of about 10mm. Water is evenly and slowly dripped into the soil near the roots of the crop through the small outlets in the drip heads or drip tapes.
Look at the color. Good drip tape is generally black, with a uniform and consistent overall color;
Look at the surface of the drip tape. The surface of a good drip tape is smooth, flat, and free of bubbles or impurities;
Look at the distance between the drip heads. A tape with even spacing between the drip heads is better;
Look at its stretchability. A good quality drip tape has strong toughness. If the tape has poor toughness, it may have added too much recycled material, which may result in visible imprints or even cracks after being folded;
Look at the cross-section by cutting a small section. A tape with uniform wall thickness is of better quality;
Burn a small section of the tape with scissors, and observe whether the smoke is significant or if it is difficult to burn. Poor quality tapes tend to produce more smoke and burn less easily.
When purchasing drip tape, these methods can be used to judge the quality of the products while ensuring product quality, which is helpful for selecting the right products.
The irrigation pipeline and drip heads are prone to clogging, requiring high water quality, and filters must be installed;
Drip irrigation cannot regulate the microclimate in the field and is not suitable for irrigation during freezing periods. Drip irrigation systems should not be used to fertilize vegetables;
Drip irrigation is relatively expensive, and the economic benefits of crops should be considered;
When installing drip tape, care should be taken to compact the ground film to position it as close to the tape as possible, minimizing the space between the ground film and drip tape, and avoiding the formation of focus points by sunlight through the water droplets. The ground should be levelled before sowing to reduce the phenomenon of uneven land. Prevent soil clods and weeds from lifting the ground film, causing water vapor to accumulate under the film and forming a lens effect that burns the drip tape. It is advisable to bury the tape to avoid burn damage.
