| 摘 要： | 以强筋春小麦品种龙麦26为试验材料,研究了施肥和密度处理对群体质量指标、产量的影响。结果表明,产量在施肥(氮磷钾纯量)180 kg/hm2,密度600万株/hm2条件下达最大值,为5 716.5 kg/hm2,其关键群体调控指标为孕穗期叶面积指数6.0,地上部干物质积累量和花后干物质积累量分别为16 899 kg/hm2和9 211.5 kg/hm2;在此施肥和密度条件下,叶面积指数在整个生育期维持在较高水平,并且后期下降较慢。

| Abstract: | The strong-gluten spring wheat Long Mai 26 was studied to investigate the effects of fertilization and density on the in-dex of population quality and yield.The results showed that the treatment of 180 kg/hm2 and 6 million individual plant/hm2 was the best treatment,the yield of this treatment was 5 716.5 kg/hm2.The highest LAI of this treatment at booting was 6.0,dry production accumulation of above ground and dry production accumulation after anthesis of this treatment were 16 899 kg/hm2 and 9 211.5 kg/ h... |
