| 1. | Relation between n absorption characteristic and dry matter production for various hybrid rice
不同杂交水稻吸氮特性与物质生产的关系 |
| 2. | Simulation and experiment of dry matter production of greenhouse cucumber under different light intensities
不同光照条件下温室黄瓜干物质生产模拟与试验研究 |
| 3. | The morphological character of rhizome is different among grass species , as well as the dry matter production , but the production in the young rhizome is more than the one in the old
不同种类禾草根茎的形态特征各异，干物质积累量也不相同，但均以幼龄根茎积累量多，老龄积累量少。 |
| 4. | The negative correlation of the dry matter production to the age class of rhizome indicates level of significance ( p < 0 . 05 , po . ol ) in leymus chinensis , calamagrostis epigeios and c . rigidula populations
羊草、牛鞭草和硬拂子茅种群根茎的干物质积累量与龄级间的负相关关系达到显著和极显著水平。 |
| 5. | As was proven by the experiment , the average harvest indexes were 0 . 62 for early rice and 0 . 61 for late rice respectively at shaoxing , while 0 . 57 and 0 . 55 for fuyang , this means that a similar rice yield at fuyang would require larger amount of total dry matter production than at shaoxing
试验证明，绍兴早稻和晚稻的平均收获指数分别为0 . 62和0 . 61 ，富阳的分别为0 . 57和0 . 55 ，这意味着同样的水稻产量在富阳需要比在绍兴更大数量的干物质生产。 |
| 6. | But the dry matter production decreased markedly with increasing ca concentration . especially p . vittata l . grew much badly under the condition treated with 5 . 0 mmol / l ca . the effects of as and ca concentration in culture solution on as content in p . vittata l . were much significant
然而，介质中高浓度的钙表现出明显的抑制蜈蚣草生长作用，特别在5 . 0mmol lca处理下，生物量极显著减少，而低钙( 0 . 03mmol lca )水平处理有利于蜈蚣草的生长，生物量较大。 |
| 7. | 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。 |
