Abstract
Experiment on different planting densities for rape cultivar Zhongshuang No. 9 was carried out. It was showed that Zhongshuang No. 9 yielded 2382.3 kg/hm2 on average under planting density of 1.65×105plants/hm2?熏 4.65%?熏 8.87%?熏 9.37% and 21.07% higher than that of 2.1×105 plants/hm2?熏 1.2×105 plants/hm2?熏 2.7×105 plants/hm2 and 7.5×104 plants/hm2?熏 respectively. The largest effect of planting density was found in total pods per unit area?熏 then on 1000-seed weight and seeds per pod. The plant agronomic traits were affected by the different planting densities. With density increasing?熏 plant height dropped?熏 the first primary branch went height?熏 the primary branches decreased?熏 pods in primary branches decreased and the ratio of pods in main inflorescence to total pods increased significantly. It was indicated thereby that the rational density benefits the increase of total pods per unit area in order to obtain high yield per unit area.
