- 摘要:
- 以早熟苹果品种“嘎啦”和晚熟苹果品种“富士”为试材，研究了限根节水对苹果叶片荧光特性和果实产量、品质的影响。结果表明：在整个处理期内限根节水处理均使“嘎啦”和“富士”叶绿素含量高于对照水平；在盛果期灌水后期，限根节水处理叶绿素荧光参数Fv/Fo、Fv/Fm、ΦPSII、qP、NPQ和ETR值均不同程度高于对照水平，说明限根节水处理显著提高了苹果叶片光化学活性，提高了水分利用率，使果实产量、品质提高。
- Abstract:
- In order to investigate the effect of brick-buring root-limiting and water-retenting water-saving technology on fruit trees in orchard，with early maturing apple varieties ‘Gala’ and late maturing varieties ‘Fuji’ in Weifang as materials，the effect of water-saving and root-limiting treatments on leaves fluorescence characteristics and yield and quality of apple in full-ruit period were studied.The results showed that，effect of water-saving treatments on leaves fluorescence characteristics and yield and quality of apple were significantly different from the control.Among them，chlorophyll content was improved，under water-saving treatments treatments.Late irrigation in full-ruit period，chlorophyll fluorescence parameters potential activity of PSII，the maximum photochemical efficiency of PSII,PSII quantum yield，apparent rate of photosynthetic electron transport，coefficient of photochemical quenching，coefficient of non-photochemical quenching were all higher than the control.This indicated that water-saving treatments improved photochemical activity of fruit，thereby increased water use efficiency and fruit quality and yield.
