| 摘 要： | 以贵农18号为材料,在氮、磷、钾配比一致的条件下,研究分析了不同施肥量对小麦生理特征及产量的影响,并对其经济效益进行评价.结果表明:在肥料用量较低的范围内,随着肥料用量的增加,处理间叶片硝酸还原酶活性、根系活力、叶绿素含量和产量差异显著,肥料对小麦生理特征及产量有明显的调控作用;在肥料用量较高的范围内,随着肥料用量的进一步增加,肥料对于增加小麦干物质积累、根系活力和叶绿素含量的促进作用变弱,处理间产量差异不显著,肥料的增产优势也不明显.综合分析表明,处理4(氮肥用量为N 270 kg/hm2,N∶P2O5∶K2O为2∶1∶1)是兼顾经济效益和社会效益的最佳选择.

| Abstract: | Guinong 18,a wheat variety,was tested under the same N,P and K ratio to study the effect of different application amount on its physiological characteristic,yield and economic benefit.The results showed that the leaf nitrate reductase activity,root vigor,chlorophyll content and yield rises with increase of application amount under the lower total application amount and there is significant difference between different treatments,which indicates that application amount has the obvious regulation effect on th... |
