摘  要:
为了探讨不同时期喷施"吨田宝"对玉米生长及其产量的影响,选用新中玉801、金玉818两个品种为材料,分别在3叶、6叶、9叶、12叶喷施吨田宝,以不喷施为对照处理。结果表明,新中玉801和金玉818在9叶期喷施吨田宝,株高分别降低43cm、48cm,产量增加5.60%、19.23%,在3叶、6叶、12叶喷施植株高度无明显变化,产量有增有减,但增减幅度小于8.50%。吨田宝在玉米上施用,对株高、果穗性状、产量都能带来一定程度的影响,施用时期是决定效果的关键因素,不同品种间施用效果存在差异。

摘  要:
In order to explore the effect of Duntianbao on maize growth and yield,two corn variety Xinzhongyu 801 and Jinyu 818 were as test materials,Duntianbao was application at 3 leaf stage,6 leaf stage,9 leaf stage and 12 leaf stage. When applied Duntianbao at 9 leaf stage,the plant height of double Xinzhongyu 801 and Jinyu 818 decreased 43 cm and 48 cm,yield increased 5. 60% and 19. 23%,respectively. However,there was no significant change about plant height,the yield changed in 8.5% range when Duntianbao used at 3 leaf stage,6 leaf age and 12 leaf stage. It can be concluded that Duntianbao have certain effect on plant height,ear character and yield,but the applying time is the major factor,the influence is different among different varieties.
