摘　　要：为研究浙江省新审定小麦品种浙华1号在浙江省稻茬麦种植模式下适宜的氮肥施用模式,2022年在浙江省小麦主产区嘉兴市平湖设置了3个氮肥梯度(0、180、210 kg/hm^(2))和2种肥料类型(常规肥料和缓释肥),对浙华1号进行产量和相关农艺性状调查。结果表明,在N 180 kg/hm^(2)条件下,不管是常规肥料还是缓释肥,浙华1号都能达到较高的产量水平,分别是6.20、5.68 t/hm^(2),比对照N 0 kg/hm^(2)(3.26 t/hm^(2))分别高2.94、2.42 t/hm^(2),其中常规肥N 180 kg/hm^(2)基追肥用量比为7∶3时,浙华1号产量最高,是适宜的施肥模式。In order to study the suitable nitrogen fertilizer application mode of the newly approved wheat variety Zhehua No.1 in Zhejiang Province under the rice stubble and wheat planting mode in Zhejiang Province,three nitrogen fertilizer gradients(0,180 and 210 kg/hm^(2))and two fertilizer types(conventional fertilizer and slow-release fertilizer)were set up in Pinghu,Jiaxing City,the main wheat producing area of Zhejiang Province,in 2022 to investigate the yield and related agronomic traits of Zhehua No.1,so as to explore the suitable fertilization mode of Zhehua No.1.The results showed that under the condition of N 180 kg/hm^(2),both conventional fertilizer and slow-release fertilizer,Zhehua No.1 can achieve relatively high yield levels of 6.20 t/hm^(2) and 5.68 t/hm^(2),respectively,which were 2.94 t/hm^(2) and 2.42 t/hm^(2) higher than the control under N 0 kg/hm^(2)(3.26 t/hm^(2)),respectively.Among them,under the fertilization mode of conventional fertilizer at N 180 kg/hm^(2) with the base topdressing ratio of 7∶3,Zhehua No.1 achieved the highest yield,indicating this is a suitable fertilization mode.
