| 摘 要： | 在烟稻轮作中,酸性土壤(pH5.0)每千克土施石灰0.2-0.4g能明显促进当季烤烟生长,但施用过多对烤烟生长不利.从石灰施用后效来看,每千克土施石灰>0.4g,明显抑制第2季水稻生长.每千克土施石灰0.2g,有利于当季和下一季水稻生长,对第3季烤烟生长无明显后效.从当季烤烟生长及后效来看,每千克土施石灰0.2-0.4g为宜,且隔季施用效果较好. |

Residual effect of lime application on farming system of tobacco-rice in acid soil |
|
| Abstract: | For the acid soil (pH 5.0) of tobacco rice farming system, the application of lime at the rate of 0.2-0.4 g·kg-1 significantly improved the growth of tabacco plants, while it was inhibited at higher rates. As to their residual effects, the second season rice yield decreased significantly in the treaments in which lime was applied at more than 0.4 g·kg-1. In the treament of applicating 0.2 g·kg-1 of lime, the first season tobacco and the second season rice were both improved, but the third season tobacco was not affected. So it was suggested that lime application to acid soil at 0.2-0.4 g·kg-1 every other season. |
