Abstract：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/hm2)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/hm2,both conventional fertilizer and slow-release fertilizer,Zhehua No.l can achieve relatively high yield levels of 6.20 t/hm2 and 5.68 t/hm2,respectively,which were 2.94 t/hm2 and 2.42 t/hm2 higher than the control under N 0 kg/hm2(3.26 t/hm2),respectively.Among them,under the fertilization mode of conventional fertilizer at N 180 kg/hm2 with the base topdressing ratio of 7∶3,Zhehua No.1 achieved the highest yield,indicating this is a suitable fertilization mode.
