| 摘 要： | 以玉米杂交种郑单958为材料，研究了3个不同沼液用量（15000、22500、30000 kg·hm-2）对夏玉米源库代谢关键酶和产量构成因素的影响.结果表明：与对照和施氮肥相比，田间浇灌沼液不仅可提高夏玉米地上部干物质量、叶面积指数和叶绿素含量，而且可提高叶片中硝酸还原酶（NR）、谷氨酰胺合成酶（GS）、蔗糖磷酸合成酶（SPS）和籽粒中蔗糖合成酶（SS）活性，从而显著增加了玉米穗粗、穗长、穗行数、穗粒数、穗粒重、千粒重和单位面积产量.在3个沼液用量中，以22500 kg·hm-2处理(拔节期、大口期、抽雄期各追施7500 kg·hm-2)对提高玉米酶活性和产量的效果最好，其产量可达14006.7 kg·hm-2，比对照增产40.7％.

| Abstract: | 15000, 22500, and 30000 kg·hm-2 of biogas liquid manure were applied to maize hybrid Zhengdan 958 to study their effects on the key source sin
k metabolism enzymes and yield components of the summer maize. Compared with CK and applying nitrogen fertilizer, the application of biogas liquid manure not only increased the aboveground biomass, leaf area index (LAI) and chlorophyll content, but also enhanced the activities of nitratereductase (NR), glutamine synthetase (GS), and sucrose phosphate synthetase (SPS) in leaves and the sucrose synthetase (SS) in grains. The yieldparameters such as ear diameter, ear length, grain rows per ear, grains per row, kernels per ear, 1000 kernel mass, and grain yield per unit area were also increased significantly. Of the three test application rates, 22500 kg·hm-2 (7500 kg·hm-2 applied at jointing, big trumpet, and tasseling stages, respectively) had the best effects on enhancing the above mentioned enzyme activities and grain yield, with the yield reached 14006.7 kg·hm-2 and being 40.7％higher than the control. |
