| 摘 要： | 以18个杂交中稻组合为材料,研究了杂交中稻地上部植株性状和施氮对再生芽生长的影响。结果表明,头季稻齐穗期单茎干物质积累量越大、成熟期满足头季籽粒灌浆后茎鞘中剩余光合物质量越多,其再生芽活芽率与出苗率越高。高再生芽活芽率和出苗率的头季稻植株重要性状表现为株高偏矮、成穗率较高。在保持较高活芽率的基础上,提高后期根系活力是进一步提高再生稻产量的重要途径。

| Abstract: | The experiment was conducted with eighteen mid-season hybrid rice combinations grown at a traditional high yield cultivation system and different nitrogen application level for promoting ratooning bud development and rate of bud emergence,in a randomized block design with 3 replications.The results indicated that the dry matter weight at full heading and the rest dry matter weight at harvesting for main rice grain filling of single mother stem were heavier,the higher bud survivat rate and the rate of bud em... |
