以青钱柳1年生苗为试材,设置4个不同的施肥处理(复合肥、有机肥、生物肥和混合肥,简称复、有、生、混),每个处理设3个不同水平(低、中、高,以L、M、H表示),研究不同施肥处理对青钱柳叶片叶绿素荧光参数的影响。结果表明:生M、有M和混M能显著提高青钱柳叶片的Fo值,分别比对照高出49%、54%和41%;生M、有M和混M处理的叶片Fv/Fm分别比对照高出15%、12%和11%;生M、有M和混M处理的叶片的Y(II)高出对照100%以上;生M、有M和混M处理的叶片的qP值高出对照80%以上。综合分析已测得的叶绿素荧光参数,生M、有M、混M能显著增加青钱柳叶片的叶绿素荧光参数,提高叶片的光合能力。
Four different fertilization treatments (compound fertilizer, organic manure, biological fertilizer and mixed fertilizer, referred to as complex, arid, raw and mixed) were set up in Qingliuli 1-year-old seedlings. Three different treatments Low, medium and high, L, M, H), to study the effects of different fertilization treatments on the chlorophyll fluorescence parameters of Cyclocarya paliurus. The results showed that the Fo values of Cyclocarya paliurus leaf were significantly increased by raw M, M and M, which were 49%, 54% and 41% higher than that of the control respectively. The Fv / Fm Were higher than that of the control by 15%, 12% and 11%, respectively. The Y (II) of the leaves of raw M, M and M were higher than that of the control by 100% Value higher than the control more than 80%. Comprehensive analysis of the measured chlorophyll fluorescence parameters, raw M, M, M mixed can significantly increase the chlorophyll fluorescence parameters of Cyanothyollum leaves, improve leaf photosynthetic capacity.
