摘要

在大田条件下，以强筋小麦豫麦34为供试材料，在330kg／hm^2（高氮）、240kg／hm^2（中氮）2个供氮水平下施用纯硫0，20，60，100／hm^2，研究了不同供氮条件下施硫对小麦光合特性及产量的影响。结果表明：在适宜的供氮水平下施硫对小麦氮同化的关键酶硝酸还原酶（NR）活性、叶绿素SPAD值、叶片可溶性蛋白、旗叶光合速率均有促进的影响，高氮条件下有随施硫量的增加NR活性、叶片中可溶性蛋白含量以及旗叶光合速率有减少的趋势。在2个供氮水平下施硫均对干物质积累量和籽粒产量影响效果明显，在N330水平下，各施硫处理的产量高低依次为S100〉S60〉S20〉S0；与S0相比，施硫处理籽粒产量分别提高了28．6％，12．6％和1．9％，S100与S20和S0相比达显著水平，S100和S60间差异不显著。在N240水平下，施硫肥处理籽粒产量分别提高了25．7％，25．3％和12．2％，S100，S60和S20差异不显著，但均显著大于S0。
