| 摘 要： | 同期播种条件下，前期地膜覆盖直播玉米的生长发育进程明显地早于育苗移栽玉米。植株的干物质累积直播玉米在前期高于育苗移栽玉米，后期以方式1和方式2育苗移栽的玉米赶上、甚至超过直播玉米，而以方式3育苗移栽的玉米则仍低于直播玉米；从根系来看，育苗移栽玉米的次生根系的发育明显优于直播玉米。籽粒产量以方式1、方式2育苗移栽的玉米为最高，其次是前期覆膜的直播玉米，而以方式3育苗移栽种植的玉米显著最低。 |

| Abstract: | The experiment was conducted to determine the effect of different establishment on maize growth and yield.The results showed that maize sown directly and covered with mulch in early stage had a high yield and a less period of growth than transplanted maize. Meanwhile the significant difference existed for transplanted maize nursed with different substrates. It suggested that the constitution of nursery substrate must be taken into account in transplanting production. |
| Keywords: | maize growth yield establishment |
