Abstract:In order to analyze the clogging risk and combined effect of the fertigation system in the groundwater with high contents of Ca2+and Mg2+, the spring maize drip irrigation in the field was experimented. The content of Ca2+and Mg2+ in the groundwater is up to 180 mg/L. Two types of irrigation water and two types of emitters were chosen. And the fertigation security problem of the groundwater with high content of Ca2+and Mg2+ and the reclaimed water was analyzed. The results show that there was a bigger security problem in fertigation with the groundwater with high content of Ca2+and Mg2+ compared with the reclaimed water. After seven times drip irrigation, the Dra and CU in the groundwater decreased to 77.6%, 79.9% respectively, and were 3.0% and 5.3% lower than those in reclaimed water. Owing to the clogging, the amount of irrigation water and fertilizer and the uniformity in the groundwater were lower than those in reclaimed water. The plant height, stem diameter, yield and water use efficiency of the spring maize in the groundwater were 7.4%, 3.5%, 3.7%, 3.7%, respectively lower than those in reclaimed water. This research can provide references for rational utilization of groundwater in the drip irrigation.
