| 摘 要： | 研究了栽植密度对神豆2号产量的影响。结果表明:神豆2号在较低密度(11.25万株/hm2)下,个体发育最好,但减产达显著水平。随密度的增大,个体发育逐渐变弱,倒伏加重,产量先增后减,其中以15.00万株/hm2群体与个体最为协调,产量达最高,较11.25万株/hm2和高于22.50万株/hm2的各处理增产显著。密度在15.00万~19.95万株/hm2的3个处理产量差异不显著,可见,神豆2号的最佳密度为15.00万株/hm2。

| Abstract: | The influence of planting density on Shendou NO.2 yield was studied.Results showed that the individual development of Shendou NO.2 was the best with the density of 11.25 thousand plants per hm2.With the increase of planting density,the individual development was faint,lodging heavier,the yield increase then decrease.The yield of Shendou NO.2 was the highest with the density of 150.0 thousand plants per hm2.It was higher than that of 112.5 thousand plants per hm2 and over 225.0 thousand plants per hm2.The yield difference of Shendou NO.2 was not significant at the density from 150.0 to 199.5 thousand plants per hm2.It was obviously that the optimum planting density was 150.0 thousand plants per hm2. |
