Shandong Hengxiang Plastic Machinery Co., Ltd. will give you a detailed explanation of the use of drip irrigation tape and the precautions when using the drip tape. When explaining the method of use, it is explained from three aspects: the adjustment of the water delivery pressure of the drip irrigation tape, the regulation of the water supply, and the technology of fertilization, so that everyone can understand the quality of the drip tape in detail during use, so that the crop yield is high and the labor efficiency is also high. A virtuous cycle. When explaining the precautions, it is explained from the blockage of the drip hole, the water pressure, the amount of fertilizer, and the storage of the drip irrigation tape.

1. How to use. ① Adjust the water delivery pressure. Adjust the water pressure to 0.03-0.05 MPa. Excessive pressure can easily cause the hose to rupture. When there is no pressure gauge, it can be judged from the operation of the drip hose. If the hose is approximately round and the water sound is not loud, it can be considered that the pressure is appropriate. If the hose is too tight and the water sound is too loud, it means that the pressure is too high and should be adjusted. ② Water supply control. The amount of irrigation water should be determined according to the different growth periods of crops and weather conditions. Generally, 20 cubic meters of water can be used for each acre (1 acre = 1/15 hectare). It is necessary to use less water during the seedling stage, more water during the vigorous growth period of crops, and more water during high temperature and drought. When there is no flow meter display, it can be calculated by the time of water supply through the hose, or judged according to the moisture content of the soil. Although the time of each irrigation is affected by factors such as water delivery pressure, soft belt diameter, number of soft belts, size and density of drip holes, and flow rate, it is generally 2-3 hours. It is more scientific to use a 75-1 soil moisture meter to supply water according to the appropriate amount of irrigation required by the crop. In actual production, vegetables irrigated with drip irrigation are often more likely to grow wildly than vegetables irrigated with traditional irrigation, so they should be properly controlled to avoid affecting the yield. ③ Fertilization technology. When fertilizing with a drip irrigation system, you can purchase a fertilization device or make your own. Connect the outlet pipe to the branch pipe of the drip hose, continuously add the dissolved fertilizer to the fertilization device, or press the fertilizer into the branch pipe with a micro pump or sprayer to complete the fertilization. Fertilization is generally carried out half an hour before the end of irrigation. The hole for introducing fertilizer should be closed when not in use.

2. Precautions. ① Prevent the drip hole from being blocked. Clean the filter device regularly, and be sure to dissolve it well and remove impurities when applying topdressing. ② Pay attention to water pressure. The pressure should be moderate to avoid the soft belt from breaking. ③ The fertilizer nutrient ratio is appropriate. ④ Keep the plastic pipes well. When not in use in summer, the pipes and soft belts arranged on the ground should be collected and stored in a place away from light and low temperature. When used again, check whether there are cracks, leaks or blockages, and re-arrange them after repair.

The above are the precautions for the use of patch-type drip irrigation tape by Shandong Hengxiang Plastic Machinery Co., Ltd., and I hope the above content will be helpful to everyone. If you still don’t understand, you can call for consultation. I will serve you with full enthusiasm.
