Someone asked, "What should I do with the drip irrigation tape due to sun burns?" For this reason, we have sorted out the causes and solutions of the drip irrigation tape due to sun burns, hoping to help growers and reduce unnecessary losses in the process of agricultural production.

One, Causes of burns on drip tape.

In the midsummer season, due to the direct sunlight and strong light, it is very easy to cause damage to the drip irrigation tape, especially the drip irrigation tape in the drip irrigation technology under the film. Water vapor will condense into water droplets on the inside of the film. Under sunlight, the water droplets will have a focusing effect. At this time, if the focus is just on the drip tape, the high temperature generated will easily melt the drip tape and cause partial melting ( ) Is commonly referred to as "sun burn") phenomenon. It is characterized in that the burned part is concentrated on the upper part of the drip tape, and there is a molten lip around it. Therefore, the conditions for forming a hole in the drip irrigation belt are: there are more and larger water droplets on the inside of the mulch in the drip irrigation system under the mulch, a certain distance between the mulch and the drip irrigation, and the soil humidity is larger.

Two, how to prevent drip tape burns?

According to the causes of drip irrigation belt burns, targeted destruction of the causes and conditions will effectively prevent the emergence of problems, as follows:

1. Use special mulch film or color mulch film for drip irrigation to block the penetration of sunlight.

2. While laying the drip irrigation tape, press and compact the mulching film so that the mulching film is as close to the drip irrigation tape as possible, and there should be no space between the mulching film and the drip irrigation tape. Avoid the focus of sunlight through water droplets.

3. Level the land before planting the crops to reduce the phenomenon of multiple pits and depressions in the land. This prevents soil, rocks, weeds and weeds from holding up the mulching film, causing water vapor to accumulate under the mulching film to form a lens effect and burn the drip irrigation belt.

4. When laying the drip tape, the drip tape can be buried to avoid focal burns.

Third, the remedy of drip tape burns.

1. If the drip tape has been burned, it can be cut off and connected by a straight-through connection. The more serious part can be replaced with a new drip tape.

2. For lighter burns, plastic film can be wound and knotted.
