| 中文摘要 | 采用Li-6400便携式光合系统仪,对黄土高原丘陵沟壑区川地和梯田茄子在覆膜与不覆膜两种栽培方式下的光合特性日变化进行了测定。结果表明:(1)茄子在川地与梯田不同栽培模式下光合速率、蒸腾速率和气孔导度的日变化均表现为"双峰"曲线,都具有明显的"午休"现象;引起川地茄子产生光合"午休"现象的主要原因是气孔因素;引起梯田茄子产生光合"午休"现象的一个重要原因是非气孔因素;(2)梯田茄子在不同栽培方式下的光合速率、蒸腾速率、气孔导度、胞间CO2浓度日均值均显著高于川地茄子(P<0.01),而叶片水平水分利用效率日均值却显著低于川地茄子(P<0.01);(3)茄子在覆膜与不覆膜两种栽培方式下的光合特性日变化参数没有显著性差别(P>0.05 |
| 英文摘要 | Li- 6400 was used to measure photosynthetic characteristic of Eggplant with plastic film covering and without covering in flatland and terrace in hilly and gully areas of the loess plateau. The results showed that ( 1) Diurnal variations of the net photosynthetic rate, transpiration rate, stomatal conductance of leaves of eggplant between flatland and terrace changed as double-peak curve in a day. It was speculated that the midday depression of eggplant in flatland was mainly caused by the stomatal factor and non-stomatal factor was one of the most important factors causing the midday depression of the eggplant in terrace. ( 2) The daily mean value of the photosynthetic rate, transpiration rate, stomatal conductance, intercellular CO2 concentrat ion of the eggplant in terrace was significantly higher than in flatland ( P < 0. 01) , while the daily mean value of the leaf water use efficiency was signif icantly lower than in flatland ( P < 0. 01) . (3) There was no significant difference between eggplant with plastic film covering and without covering both either in flatland or terrace ( P > 0. 05) . |
