| 摘 要： | 种植密度对单位面积上玉米的产量有重要影响，不同种植密度热带玉米的营养价值基本相同，干物质消化率及其他参数相似。在某一生产环境中，如果随着种植密度的增加饲草量继续增加而消化率又不明显下降，并且不受到伏等其他因素的影响，那么较高的种植密度是必要的。

| Abstract: | Corn plant population has important effect on the maximizing production of corn in unit area. The forage nutritive values of tropical corn in different plant densities were similar,dry matter digestibility and other forage nutritive value parameters were also similar. For a given production environment, if forage mass is continues to increase without a significant reduction in digestibility as plant density increase, higher plant density would be desirable (unless lodging or some other factors limit production). |
