中文摘要	以陇薯3号为材料, 设C_1 (0. 5% 保水剂+钾肥60 g·hm~(-2))、C_2(钾肥60 g·hm~(-2))、C_3(0. 5%保水剂)、CK(对照)4个试验组,测定叶绿素荧光参数、块茎产量、商薯率等产量指标,从光合效能的角度探讨了保水剂、钾肥对旱地马铃薯叶绿素荧光参数和块茎产量的影响。结果表明:C_1处理的出苗率较对照组显著提高9. 4%;所有处理的冠幅、茎粗等指标不同程度地高于对照;除C_3组中的NPQ 值低于对照之外,其余处理的叶绿素荧光参数F_v / F_m、(F_m′-F_o′) / F_m′、qP、ETR 日均值较CK 均有不同程度提高,(F_m′-F_t) / F_m′日变化成V型;C_1组商薯产量最高;保水剂和钾肥直接影响马铃薯叶绿素荧光动力学参数, 增强其光合效能,从而提高旱地马铃薯商品薯产量。
英文摘要	Taking the potato cultivar Longshu-3 as the object, this paper studied the tuber yield and chlorophyll fluorescence parameters under effects of different applications of super absorbent polymer and potassium fertilizer, aimed to approach the effects of applying super absorbent polymer and potassium fertilizer on the yield index and chlorophyll fluorescence parameters of dry land potato from the viewpoint of photosynthetic efficiency. Four treatments were installed, i. e., 0. 5% of super absorbent polymer + 60 g·hm~(-2) of potassium fertilizer (C_1), 60 g·hm~(-2) of potassium fertilizer (C_2), 0. 5% of absorbent polymer (C_3), and no super absorbent polymer + no potassium fertilizer (CK). As compared with CK, the emergence percentage in treatment C_1 increased significantly by 9. 4%. The crown and stem diameter in treatments C_1, C_2, and C_3 were all higher than those in CK, and, except the NPQ in treatment C_3 being lower than that in CK, the mean diurnal F_v / F_m, (F_m′-F_o′) / F_m′, qP, and ETR in treatments C_1, C_2, and C_3 were also increased to some extent. The yield index was the highest in C_1. All the results indicated that super absorbent polymer and potassium fertilizer had direct effects on the potato plant chlorophyll fluorescence parameters, manifesting in the increase of photosynthetic efficiency, and thus, improved the tuber yield of upland potato.
