| 摘 要： | 通过水稻秸秆全量还田条件下不同插秧密度的试验,初步探索了水稻生育及产量的影响,为秸秆还田技术的研究提供科学依据。结果表明,对叶龄动态影响无明显差异,但促进水稻生长中后期的分蘖数,而插秧密度的增加分蘖数变少,株高也变低。对经济性状来看,插秧密度的增加,提高结实率和产量。S

| Abstract: | Through the experiment of different transplanting density under the condition of rice straw returning to the field, the effect of rice growth and yield was explored preliminarily, which provided scientific basis for the research of straw returning to the field. The results showed that there was no significant difference in leaf age dynamics, but the number of tillers was promoted in the middle and late stages of rice growth, while the increase in seedling density decreased the number of tillers and the plant height became lower. In terms of economic traits, the increase in seedling density increases the seed setting rate and yield. |
