Abstract：Using multiple spike type wheat variety Jimai 22 and large spike type wheat variety Tainong 18 as materials,the suitable sowing time and planting density were studied in central Shandong Province.The results showed that with the delay of sowing time,the yield and spike number per hectare increased firstly and then reduced,while the kernels per spike decreased gradually.With the increase of planting density,the spike number per hectare increased,while the kernels per spike and thousand seed weight decreased.During 201 1 ~2012,the optimum sowing time was October 7th,and the suitable planting density of Jimai 22 and Tai-nong 18 were 180 ×104 and 240 ×104 plants per hectare respectively.
