摘  要：
【目的】探讨缓释复合肥对扦插莲雾叶绿素荧光参数的影响,为其种苗智能化快繁技术的应用提供参考依据。【方法】莲雾扦插苗床基质为珍珠岩,插前根据缓释复合肥施用量设0(CK)、50、100、150和200 g/m2 5个处理,插后90 d对各处理插穗叶片的叶绿素荧光参数[PSII有效光化学量子产量(YIELD)、光合电子传递速率(ETR)、光化学猝灭系数(q P)和非光化学猝灭系数(q N)]及光响应曲线进行检测。【结果】施用缓释复合肥能有效提高莲雾叶片YIELD、ETR和q P,降低其q N,其中以100 g/m2处理效果最佳,50 g/m2处理的效果次之。暗适应后,莲雾插穗叶片的YIELD和q P仍以100 g/m2处理最高,CK处理最低。各处理莲雾插穗叶片的光响应曲线变化趋势基本一致,且叶片ETR随光照强度的增强而逐渐上升,但光照强度超过800μmol/m2·s时,叶片ETR上升幅度减小,各处理间的ETR变化趋于平稳。【结论】在莲雾种苗智能化快繁中,施用缓释复合肥能有效提高插穗叶片的光合能力,施用量以50~100g/m2为宜。

摘  要：
【Objective】The effects of slow-release compound fertilizer(SRCF) on chlorophyll fluorescence parameters of Syzygium samarangense cutting leaves were investigated, in order to provide references for applying intelligent rapid propagation technology of S. samarangense seedling. 【Method】All S. samarangense cuttings were cultured on nursery bed with perlite matrix. Before cutting, five treatments viz., 0(CK), 50, 100, 150 and 200 g/m2 SRCF were set. Then, on the 90 th day after cutting, the effects of every treatment on light-response curve of S. samarangense cuttings and chlorophyll fluorescence parameters including effective quantum yield of photosystemⅡ(YIELD), electron transfer rate(ETR), photochemical quenching(q P) and non-photochemical quenching(q N) were detected. 【Result 】The results showed that, the real-time YIELD, ETR and q P of S. samarangense leaves were increased by applying SRCF, while q N was decreased. Particularly,100 g/m2 SRCF had the best increasing effect on YIELD, ETR and q P of S. samarangense leaves, followed by 50 g/m2 SRCF.After dark adaptation, YIELD and q P of S. samarangense cutting leaves of 100 g/m2 SRCF treatment were also the highest,but those of CK treatment were the lowest. Furthermore, as for all treatments, the change trends of leaf light-response curves were basically consistent, and ETR increased gradually with the strength of illumination intensity. But when illumination intensity was more than 800 μmol/m2·s, the increasing range of ETR decreased and the ETRs of different treatments changed to be steady. 【Conclusion】The photosynthetic capacity of S. samarangense cutting leaf can be improved effectively by applying SRCF, and the appropriate application rate of SRCF was 50-100 g/m2 in intelligent rapid propagation of S. samarangense seedlings.
