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／hm^2。）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／hm^2。群体与个体最为协调，产量达最高，较11.25万株／hm^2。和高于22.507万株/hm^2的各处理增产显著。密度在15.00万～19.95万株／hm^2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／hm^2。
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 hm^2. 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 hm^2. It was higher than that of 112.5 thousand plants per hm^2 and over 225.0 thousand plants per hm^2. The yield difference of Shendou NO. 2 was not significant at the density from 150.0 to 199.5 thousand plants per hm^2. It was obviously that the optimum planting density was 150.0 thousand plants per hm^2.
