| 1. | The thy matter weight per unit , thy matter accumulation per stem ( panicle ) , and transportation of leaf apparent matter was more than the high yield crop management
与传统高产栽培管理比较，单位面积干物重、单茎物质积累量和叶片的物质表观转出量高。 |
| 2. | This implied that alter the abortion of the stamens the soluble materials were partly carried to pistils , resulting in the extraordinary expansion of the pistils
暗示可能雄蕊败育后降解的生物大分子物质被部分运到了雌蕊，才引起了雌蕊干物重的异常增加。 |
| 3. | The dry matter weight of single stem , shoot in full heeding stage and spikes in mature stage of songjing no . 9 were significant higher than thoes of the other two check varieties
摘要松粳9号齐穗期单茎干重、齐穗期地上部干物重、成熟期稻穗干物重均极显著高于两个对照品种。 |
| 4. | For a given rice variety , the crop harvest index , which is calculated by the grain yield divided by total dry matter produced above ground , may vary with crop management practices used
对于给定的水稻品种，作物收获指数（由籽粒产量除以地上部分总干物重求得）可能随作物管理措施不同而变化。 |
| 5. | Although the difference between the yields in - zn treatment and opt was not significant , the tendency was clear that zn might become a yield limiting factor for a high yield production in the field
尽管不施锌处理和最佳处理的干物重没有显著差异，但锌在田间高产情况下很可能是产量限制因素之一。 |
| 6. | Wether in three or 1 eight weeks , the biomass ( dry matter ) of rape and rice decreased significantly for higher re treatments , and the inhibition of re to the rice was stronger than to the rape
无论短期或长期内，高浓度稀土处理均显著地降低油菜和水稻的生物量(以干物重计) ，且对水稻生长的抑制作用更为明显。 3 |
| 7. | According to the correlation analysis , the dry mater weight of single stem in mature stage , dry mater weight of shoot in full heading time and dry matter weight of spikes in mature stage were very significant positive correlated to yield
通过相关分析，成熟期单茎干物重、齐穗期和成熟期地上部干物重、成熟期稻穗干物重与产量呈极显著正相关。 |
| 8. | Salt stress can decrease the total content of n on shoot obviously , but this change has no relation with time . under salt stress , threr is a positive correlation between n content and dry mass . perhaps the nacl - induced inactivation of photosystems was the reason of this phenomenon
随着nacl水平的提高，全n含量和干物重的变化有很强的正相关性，光合作用过程因盐分胁迫而被顿化可能是这一现象的根本原因。 |
| 9. | 2 . in rhizosphere culture experiment , re applications with appropriate dose in three weeks significantly increased the biomass ( dry matter ) of rape and rice , and the effects of re on the rape was better than the rice , but they decreased or became little significant in eight weeks
根际培养条件下，第三周低浓度稀土处理显著提高油菜和水稻的生物量(以干物重计) ，对油菜的作用效果优于水稻，第八周作用趋缓或不明显。 |
| 10. | The results showed that the treatment of oxygen supply in the rhizosphere increased significantly the eh of soil and the dry matter production of the organs , promoted early tillering , and increased the productive panicles per plant , primary branches and grains per panicle , resulting in a markedly hither grain yield ( 8 . 8 % more than that of the ck )
结果表明，与淹水处理相比，根际供氧能提高稻田土壤氧化还原电位，提高各器官的干物重，促进分蘖早发，增加有效穗数、一次枝梗数和每穗实粒数，具有显著的增产效果。 |
