摘要: 通过田间试验,研究了施磷量、施磷深度和不同水分条件对冬小麦不同生育期土壤中氮、磷养分含量的影响。结果表明,在3种处理条件下,土壤中NO3-_N随小麦各生育期对氮素需求量而变化,在返青期和灌浆期,其在土壤中的含量均出现最低谷;土壤中的NH4+_N的含量在孕穗期出现高峰,其他生育期含量变化无明显影响;同样,土壤中有效磷含量在返青期和灌浆期出现低谷,而拔节或孕穗期达到高峰。根据土壤中氮磷养分的动态变化,推荐整个生育期灌水2次,施磷量及施磷深度分别为225kg/hm2和30cm。

关键词: 冬小麦, 氮,

Abstract: In the field experiment,the effect of different amounts and depths of P applied and water conditions on N and P concentrations in soil during different period of winter wheat were studied.The results showed that the concentrations of NO3-_N changed with N-uptke by winter wheat in different growing period,the concentrations of NO3-_N was lower at both reviving stage and filling stage.Water situation and the rate of fertilizer_P applied had no significant effect on the concentrations of NH4+_N except for booting stage;The contents of available P had some correlation with uptake of N and P in every period of winter wheat.

Key words: Winter Wheat, NO3-_N, NH4+_N, Available P
