| 摘 要： | 控制土壤和地上部营养空间观察玉米生育和产量的结果表明：改善空间因子使玉米增产17.0%，而改善土壤因子仅使玉米增产13.0%。土壤和地上部营养条件对穗粒数的影响高于对千粒重的影响，开花以前土壤因子是决定生长的主要矛盾，而开花以后空间因子则是决定生长的主要矛盾。 |

| Abstract: | The experiments were carried out to investigate soil and spatial factor on growth and grain yield in maize.The results showed that improving spatial factor increased grain yield 17.0% and improving soil nutrient volume increased grain yield 13.0%.The effect of soil and spatial factor on kenerals were more greatly than that on grain weight.Before silking,soil nutrient volume was more important than Spatial factor to determine growth of plants.After silking,spatial factor was more than soil nutrient to determine growth of plants. |
| Keywords: | Maize Soil and spatial factor. |
