| 中文摘要: |
| 通过盆栽试验，研究缓释肥料对番木瓜叶片光合和叶绿素荧光特性的影响。结果表明，施用缓释肥料促进番木瓜叶片叶绿素的合成，提高番木瓜叶片的净光合速率、气孔导度、蒸腾速率、光化学量子产量、光合电子传递速率、光化学淬灭系数、非光化学淬灭系数，降低胞间二氧化碳浓度和非光化学淬灭系数，其中以缓释肥料SRF-4处理的效果优于SRF-3处理和复合肥CPF处理。 |
| 英文摘要: |
| A pot experiment was conducted to study the effects of slow-release fertilizers on photosynthesis and chlorophyll fluorescence characters of papaya leaves. The results showed that the net photosynthetic rate, transpiration rate，stomata conductance effective quantum yield of photosystemⅡ(Yield), electron transfer rate(ETR) and photochemical quenching (qP) increased by usage of slow-release fertilizers, and non-photochemical quenching (qN), but the intercellular CO2 concentration（Ci） and non-photochemical quenching (qN) decreased by usage of slow-release fertilizers. The results also showed that use of slow-release fertilizer SRF-4 has the best effects on photosynthesis and chlorophyll fluorescence characteristics of Papaya than use of slow-release fertilizer SRF-4 and common fertilizer(CPF). |
