Effect of Different Planting Density on Dry Matter Accumulation of Zhangzagu 5
摘要
Abstract
The effects of different planting density(75 000,150 000,225 000,300 000 plant per ha) on dry matter accumulation of Zhangzagu 5 were studied. The results showed that the dry matter accumulation of Zhangzagu 5 showed the slow-quick-slow trend during the whole growth period;under the planting den-sity of 150 000 plant per ha,the dry matter accumulation of Zhangzagu 5 was 100. 82 g per plant, the dry matter accumulation of spike per plant was 79. 94 g,the transportation rate of leaf and stem were 24. 73%and 26 . 82%, the contribution rate to seed of leaf and stem were 8 . 55% and 14 . 87%, the yield was 7 477. 37 kg/ha,overall,all indexes of Zhangzagu 5 under the planting density of 150 000 plant per ha were higher than that under the other three planting densities. The planting density of 150 000 plant per ha was the best planting density for Zhangzagu 5 .关键词
