| 摘 要： | 研究了泰山21号的单株最大产量潜力和7个种植密度下的群体动态、产量性状和干物质积累情况。结果表明,在不同的种植密度下,泰山21号的分蘖动态和鲁麦14号有明显的区别,干物质积累和产量都明显高于鲁麦14号,尤其是在拔节至抽穗期和抽穗到成熟期的干物质积累明显高于鲁麦14号,且在耐密性和抗倒性上表现出较大的优势。当基本苗为120-180万/hm2时,泰山21号产量达到最高。

| Abstract: | A field experiment was carried out to study the yield potential of single one and tillering trends, yield and accumulation of dry matter under condition in 7 plant densities of Taishan21. The results were shown as follows: Tillering trends of Taishan21 has obvious difference with Lumai14. Its accumulation of dry matter and yield was higher than Lumai14. Taishan 21 has more accumulation of dry matter in the period of jointing to heading and heading to mature. It has higher density resistance and higher lodging resistance than Lumail4. The yield of Tais han21 has the highest yield when its plant densities were between 120 * 104/hm2 to 180 * 104/hm2. |
