摘　　要：在吉林省北部半干旱区以玉米先玉335为试验材料,研究不同磷肥施用水平对玉米叶绿素动力学参数和品质的影响。结果表明,在当地土壤肥力状况下,适当增施磷肥可以提高叶片中叶绿素的含量,提高叶绿体光系统Ⅱ的光化学效率;磷对春玉米品质有一定影响,增施磷肥使春玉米子粒中的淀粉含量和容重有明显增加,而对蛋白质和粗脂肪的影响相对较小。叶绿素含量和玉米品质极显著正相关。A field trial was carried out to study the effects of phosphorus（P） application on Chlorophyll fluorescence characteristic and phosphorus fertilizer efficiency and quality of spring maize use maize named Xianyu335 with different phosphorus rates at the semi-arid area in Jilin province. The results showed that soil fertility in the local circumstances, appropriate rate of P application could enhance leaf chlorophyll content, chloroplast photosystem Ⅱ photochemical efficiency. Maize grain starch and test weight content had also significantly increased, but had a less impact in protein and crude fat content of spring maize. Chlorophyll contents were positively correlated to quality.
