Abstract:

The experiments were focused on investigating the effects of six row spacing on economic characteristic and yield of rapeseed in different plant density. The main results were as follows, there were little significance effect among the six various row-spacing in the planting density of 15×104 plant/hm2, but there were significant difference among the six ones in the density of 45×104plant/hm2, and the maximum yield increased by 19.1%. The experiment results of various row spacing showed that the best row spacing for current direct-seeding rapeseed was 20 cm-40 cm one.
