| 摘 要： | 采用单因素随机区组试验设计,设置6个施氮水平,在基穗肥比为1︰2的条件下,研究了施氮量对苏玉10号产量形成的作用。苏玉10号的施氮量试验结果表明：在适宜密度基础上,产量（Y）与施氮量（X）的关系为Y=-0.066 9x^2＋37.476x＋5 454.3（R^2=0.873 5^＊＊）,最佳施氮量为280.1 kgN·hm^-2。

| Abstract: | The single factor randomized block design was used to study the effects of six different nitrogen levels(ratio of basal to ear nitrogen fertilizer was 1︰2) on the yield formation of ’Suyu 10’.The results of the nitrogen fertilizer rate of ’Suyu 10’ show that on the basis of appropriate plant density,the relationship between the yield(Y) and the nitrogen fertilizer rate(X) is Y=-0.066 9x2+37.476x+5 454.3(R2=0.873 5**),and the best quantity of nitrogen fertilizer is 280.1 kgN-hm-2. |
