e0“Further increasing the amount of irrigation to sufficient irrigation treatment could increase the total stem number per plant at wintering and jointing stage, but there was no significant difference with water-saving irrigation in the total formation spike number per plant, spike number, and grain yield per hectare, water use efficiency was decreased.”
