| 摘 要： | 在同期播种情况下,和粳稻相比,杂草稻出苗时的叶片更肥长、营养生长期的植株更高、分蘖数多达4倍以上。不同生物型杂草稻的落粒性差异较大。杂草稻密度愈高对栽培粳稻的产量影响愈大。 |
| 关 键 词： | 杂草稻 栽培粳稻 产量 |

| Abstract: | Under the condition with the same sowing date,the leaves of weedy rice(Oryza sativa f.spontanea) were longer than that of Oryza sativa subsp.japonica at germination stage;the plants of Oryza sativa f.spontanea were higher than that of Oryza sativa subsp.japonica in the period of vegetative growth;and the tillers were more than 4 times than that of Oryza sativa subsp.japonica.Seed shattering in different biotype of weedy rice was quite different.If the growth density of weedy rice is higher,the effrcts of weedy rice on the harvest yield Oryza sativa subsp.japonica could be bigger enough. |
