Abstract: To clarify high yield and high efficiency cultivation measures of new winter wheat cultivar ‘Heng6632’, and provide a theoretical basis for large-scale application of the cultivar, the authors studied the effects of sowing dates and planting densities on yield and its components. The test was conducted with split-plot design, including 5 sowing dates and 6 planting densities, and was carried out in Dry-farming and Water-saving Experiment Station located at Hujiachi Town Shenzhou City of Hebei Province during 2014-2015. The results showed that: (1) the effect of sowing dates was significant on the number of spike per unit area, 1000-kernel weight and grain yield except kernels per spike, the effect of planting densities was significant on both grain yield and its components; (2) the yield first increased and then decreased with the delay of the sowing date and the increase of the planting density; the number of spike per unit area decreased with the delay of the sowing date and increased with the increase of planting density in a certain range; the kernels per spike and 1000-kernel weight increased with the delay of the sowing date; the kernels per spike decreased with the increase of planting density when the planting density was above 3000 thousands/hm², the 1000-kernel weight decreased with the increase of planting density. Analysis showed that under 1 irrigation in spring, the suitable sowing date of ‘Heng6632’ was October 7^th -19^th, the best sowing date was October 10^th-15^th, and its suitable planting density was 2250 thousands-3000 thousands/hm².
