摘　　要：以本地区主推品种伟科702为试验材料,研究缓释肥对春玉米干物质积累与转运的影响.试验以复合肥+尿素和缓释肥+尿素为试验组,同时以常规施肥为对照组.结果表明,不同肥料处理下春玉米干物质积累量,缓释肥+尿素处理高于复合肥+尿素处理和常规施肥;器官干物质转运量、转运率及籽粒贡献率,缓释肥+尿素处理低于复合肥+尿素处理和常规施肥;籽粒产量,缓释肥+尿素处理较复合肥+尿素处理高0.86%(2015年)和1.83%(2016年),较常规施肥处理高1.53%(2015年)和2.94%(2016年).The responses of slow release fertilizers on dry matter accumulation and translocation in spring maize varieties were studied.Field experiments were conducted using Weike 702,the main variety grown in the local area.Compound fertilizers-urea(FN)and slow release fertilizers-urea(HN)were compared to a conventional fertilization treatment(CK).Dry matter accumulation using HN was higher than that of FN and CK under different fertilizer treatments.Organic dry matter translocation,translocation rate and contribution ratio of the HN treatment was less than that of FN and CK treatments.The yield in the HN treatment was much higher than the FN by 0.86%in 2015 and 1.83%in 2016.It was also 1.53%higher in 2015 2.94%higher in 2016 compared to the CK treatment.
