1. Drip irrigation pipes and drippers are easy to clog, and the water quality requirements are high, so filters must be installed;

2. Drip irrigation cannot adjust the microclimate in the field, and is not suitable for irrigation during the freezing period. Drip irrigation systems cannot be used to apply manure in vegetable irrigation.

3. Drip irrigation investment is high, and the economic benefits of crops must be considered;

4. Pay attention to compacting the ground film when laying the drip irrigation tape, so that the ground film is as close to the drip irrigation tape as possible, and there should be no space between the ground film and the drip irrigation tape. Avoid the focus of sunlight through water droplets. Level the land before sowing to reduce the phenomenon of multiple pits and depressions in the land. Prevent soil, rocks and weeds from lifting the ground film, causing water vapor to accumulate under the ground film to form a lens effect and burn the drip irrigation tape. The drip irrigation tape can be buried during laying to avoid focal burns.

The correct way to use the patch drip irrigation tape is as follows:

1. Pay attention to the water pressure of the patch drip irrigation tape. The pressure should be moderate to avoid the patch drip irrigation tape from breaking.

2. The fertilizer nutrient ratio is appropriate.

3. Prevent the patch drip irrigation tape from clogging. Clean the filter regularly, and make sure to dissolve it well and remove impurities when applying topdressing.

4. Keep the plastic pipes well. When not in use in summer, the pipes and soft tapes placed on the ground should be collected and stored in a dark and low temperature place. When used again, check whether there are any cracks, leaks or blockages, and re-arrange them after repair.
