| 摘 要： | 为探明水稻混作对其生长性状的影响,选择两个品种水稻种子以1∶1比例混合种植,进行水稻苗期盆栽试验。结果表明,混作有使水稻苗高变矮、苗期地上部生物量减少、地下部生物量增加的趋势,也能有效减少水稻苗期叶绿素含量及根系活力的下降幅度。

| Abstract: | In order to probe effects of mixed planting of different rice varieties on seedling growth,two rice varieties at the ratio of 1 ∶1 were selected and mix-planted through pot trial.The results showed that compared with the mono-cropping treatments(The control),the rice height and shoot biomass of rice plant decreased,and the root biomass increased during the rice seedling stage.Moreover,the decline of chlorophyll content and root activity of rice plant was slowed down in the mixed planting treatment. |
