In the silted area of the lower Yellow River,crops such as suitable forests and grass are planted,and some of them use drip irrigation.During the high temperature period from June to August each year,during the non drip period of 4-8 days in the forest drip irrigation project,the remaining water that does not flow out of the drip chamber laid on the ground PE plastic capillary(used for many years)inevitably forms scale during the evaporation process,and after years of accumulation,it may eventually form blockage.By collecting data on ground temperature and water quality,as well as conducting on-site observations,and utilizing relevant achievements and data,the relationship between surface soil temperature and the formation of scale in the inner cavity of drip irrigation heads in silted areas has been preliminarily revealed,and corresponding solutions have been proposed.
