| 摘 要： | 采用大田随机区组设计,研究了播种量和氮肥用量对"绿旱一号" 旱直播栽培穗部性状及产量的影响.结果表明:在氮肥水平相同的条件下,随着播种量的提高有效穗数增加,穗长、穗实粒数及分枝数下降;在播种量较低的条件下,增加氮肥用量可提高有效穗数和穗长度,但在高播量的情况下,增加氮肥用量对增加有效穗数及穗长度效果不明显;播种量和氮肥用量对穗粒数、粒重及着粒密度影响效果不明显;各个处理中,以A2B2处理产量最高,A2B3处理的产量次之,即播种量在40～60kg/hm2范围内,氮肥用量(纯氮)在270kg/hm2左右易获得高产.

| Abstract: | By methods of field trials and randomized blocks design,the seeding amount and nitrogen fertilizer on character of ear and yield of LvHan No 1 under direct-sowing dry culture condition were studied in this experiment.Under the same amount of nitrogen applied fertilizer,the result indicated that the spike number increased,and the length and full grain and branch of panicle were decreased with the raise of seed quantity.Under the lower seed quantity,the panicle and length of panicle increased with the raise o... |
