中文摘要	[目的]检验根施氮、磷、钾肥对轮台白杏叶片光能转换效率(Fv/Fm)的影响,为轮台白杏的田间施肥管理提供科学依据。[方法]采用3414肥料效应田间试验和逐步回归分析。[结果]轮台白杏光能转换效率(Fv/Fm)的常用对数与氮肥施用量呈显著线性正相关,与磷肥施用量不相关;当钾肥(K_2O)施用量超过0.258 7 kg、株时,对轮台白杏的光能转换效率存在负效应。[结论]在高温、高光照、低空气湿度绿洲灌溉条件下,根施氮肥和一定量的钾肥,有利于缓解由气孔因素引起的轮台白杏叶片光能转换效率的下降。
英文摘要	[Objective]In order to provide scientific basis which was used in field fertilization management of Armeniaca vulgaris ’Luntaibaixing’, the effect of fertilizer on foliar light energy conversion efficiency (Fv/Fm) of A. vulgaris ’Luntaibaixing’, which was compounded by nitrogen, phosphoric and potassium, was tested.[Method]’3414’ fertilizer effect field experiment and stepwise regression analysis were used.[Result]The common logarithm of the light energy conversion efficiency (Fv/Fm) of A. vulgaris ’Luntaibaixing’ had significant linear positive correlation with the nitrogenous fertilizer, but not with the effect of phosphate fertilizer; the potassium had the negative effect on the light energy conversion efficiency when potash fertilizer (K_2O) seemed more than 0.258 7 kg on per tree.[Conclusion]Under the oasis irrigation conditions of high air temperature, high illumination intensity, low air humidity, root fertilization by the nitrogenous fertilizer and a certain amount of potash fertilizer was able to alleviate decline of the light energy conversion efficiency of A. vulgaris ’Luntaibaixing’ which was caused by stomatal factors.
