| 摘 要： | 利用裂区试验研究了追肥时期和种植密度对小麦新品种豫农202产量及其构成因素的影响.结果表明,追肥时期对豫农202产量的影响达到显著水平,对其产量构成因素影响较小,均不显著;种植密度则影响较大,除对千粒重的影响不显著外,对穗数和穗粒数影响达到显著水平,对产量的影响达到极显著水平.在不同的肥力条件下,各种植密度间产量差异较...

| Abstract: | A split-plot experiment was carried out to study the effects of top-dr essing time and planting density on yield and components of new wheat cultivar Yunong 202.The results showed that top-dressing time had a significant effect on yield but not on its components.Planting density had a highly significant effect on yield and on the spike number per hectare and grain number per spike but not on 1 000-grain weight.There were great yield difference and some components difference among planting densities in diffe... |
