摘要: 为探究不同比例沼肥与化肥配合施用对春玉米(Zea mays L.)生长性状的影响,选择春玉米品种金海5号作为试验材料,设置6个不同施肥处理,分别为CK(不施肥)、HF(化肥)、ZH20(20%沼肥+80%化肥)、ZH50(50%沼肥+50%化肥)、ZH80(80%沼肥+20%化肥)、ZF100(100%沼肥),5个施肥处理以施氮352.5 kg/hm2为基准。试验采用随机区组设计,研究了不同施肥处理对春玉米在拔节期、小喇叭口期、大喇叭口期、抽穗吐丝期和收获期5个关键生育期的叶片发育、株高、结穗性状及光合作用的影响。结果表明,100%沼肥处理在拔节期和大喇叭口期时促进叶片生长效果最明显;大喇叭口期之前,化肥比例越高的处理可显著提高玉米叶片叶绿素含量,大喇叭口期之后差异不明显。

Abstract: : The purpose of this experiment is to study the effects of combined application of biogas manure and chemical fertilizer in different proportions on the growth traits of spring maize (Zea mays L.). Spring maize variety Jinhai No.5 was selected as experimental material and 6 different fertilizer treatments were set up, labelled as CK(no fertilizer), ZH20(20% biogas manure+80% chemical fertilizer), ZH50(50% biogas manure+50% chemical fertilizer), ZH80(80% biogas manure+20% chemical fertilizer), ZF100(100% biogas manure). The nitrogen application of the 5 fertilization treatments were all 352.5 kg/hm2. Filed trails were conducted in randomized block design to study the effects on leaf development, plant height, earing traits and photosynthesis in five key growth stages (jointing stage, small bell-mouthing stage, big bell-mouthing stage, tasseling and silking stage and physiological maturity). The results showed the application of 100% biogas promoted leaf growth most obviously at jointing stage and big bell-mouthing stage; Before big bell-mouth stage, the treatments with higher proportion of chemical fertilizer significantly improved the contents of chlorophyll, and there was no significant difference after big bell-mouth stage.

Key words: biogas manure, chemical fertilizer, spring maize(Zea mays L.), growth traits
