But the negative impact of mulching lies in the transportation of photosynthesis production to stalk and leaf.

但覆膜的负面效应在于使更多的光合产物流向茎叶。

The primary resistances for CO2 diffusion are thought to be at the stomata and at photosynthesizing cells via a combination resulting from resistances of aqueous solution as well as the plasma membrane and both outer and inner chloroplast membranes.

CO2扩散速率的主要限制因素不仅与气孔和光合细胞中它的水溶性有关，还与质膜和叶绿体内外膜有关。

Improving the activity of SOD can postphone aging of leaf and decreasing of photosynthesis, decrease the exportation of carbohydrate of stem-sheath matter, promote transportation of carbohydrate to axillary buds, and increase the ratooning ratio.

提高叶片中SOD活性，能有效延缓叶片衰老，延缓叶片光合同化作用的下降，减少茎鞘碳水化合物的输出，促进茎鞘碳水化合物向腋芽输送，促进腋芽萌发，提高水稻再生率。

The results showed:Under the same fertilizer consumption,covered with straw and covered with film can increase the chlorophyll content and total leer area duration of the maize,can improve leaf nitrate reeducates activity,Photosynthesis and roots vigor,and the nitrate reeducates activity,the chlorophyll content and the roots vigor present positive correlation with yield. Meanwhile,average dry matter accumulation of straw-covered increased 7.1% than this of no-ploughed,yield increased 15.3%.The average dry matter accumulation of film-covered increased 20.1% than which of no-ploughed and 12.1% than which of plough and covered with straws.And yield increased 26.8% and 10.1%,notable differences.

结果表明：在相同的肥料用量条件下，秸秆覆盖和薄膜覆膜对玉米生长发育具有良好的促进作用，能显著增加玉米叶片叶绿素含量和光合势，增强叶片硝酸还原酶活性和根系活力，同时玉米叶片硝酸还原酶活性、叶绿素含量、根系活力等与最终籽粒产量呈正相关；秸秆覆盖比免耕全生育期平均单株干物质积累量增加7.1%，籽粒产量增加15.3%，薄膜覆膜分别比免耕和翻耕残茬覆盖全生育期平均单株干物质积累量增加20.1%和12.1%，最终籽粒产量增加26.8%和10.1%，差异显著。

The larger velocity and more times Aeolian flow was, the greater the decrease of net photosynthetic ratio was.

风速大、吹风次数多的风沙流使净光合速率降低幅度大，并对植物的物质积累与生长发育影响大。

Based on the field experiments, the daily variations of photosynthesis rate and transpiration rate and water use efficiency were compared on the condition of sprinkle irrigation and border flooding irrigation.

通过定点定位试验，比较了喷灌与常规畦灌条件下农田生态环境、冬小麦光合速率和蒸腾速率的日变化特征以及不同水平的水分利用效率。

The leaf area index, photosynthetic potential and dry matter accumulation were lower for the SHY rice than those for the CK at the early growth stage, and their differences were not significant between the two rice types at heading, and were greater for the former than the later after heading. The root-shoot ratio at each growth stage, root bleedings from heading to maturity, grain-leaf ratio, translocation percentage of the matter from stems and sheaths and harvest index of SHY rice were greater than those of CK.

超高产水稻各生育时期的根冠比、抽穗至成熟的根系伤流量以及粒叶比、茎鞘物质运转率和收获指数均显著高于CK；超高产水稻花后叶面积指数、剑叶叶绿素含量、光合速率、PSⅡ最大光化学效率均显著高于对照，非光化学猝灭系数显著低于对照。

It is studied on photosynthetic characteristics of four different heat-tolerance capsicums in alimentation growth periods by CI-301PS CO2 GAS ANALYZER, for probing into the relation between photosynthetic parameter and capsicum heat-tolerance.

为了探讨光合作用参数与辣椒耐热性的关系，通过用CI-301PSCO2气体分析仪对4个不同耐热性辣椒育种材料营养生长期的光合特性进行了测定研究。

As pioneer plants, desert spring ephemerals play an important role in community succession, biodiversity maintenance and dune stabilization in desert ecosystems. We studied the diurnal changes in gas exchange of three desert spring ephemerals (Eremopyrum orientale, Malcolmia scorpioides, and Tetracme quadricormis, hereafter the genus names only) under natural conditions in the desert area of the Dzungaria Basin.

采用LI-6400便携式光合测定仪，在晴天条件下对准噶尔荒漠3种典型短命植物东方旱麦草、卷果涩芥和四齿芥的气体交换特征的日变化规律进行了研究。

Photosynthesis, the characteristic function belongs to eucaryotic photosynthetic creatures, is the unique way to fix the solar light.

光合作用是唯一能将太阳能固定的真核光合生物所特有的功能。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
