摘要: 试验采用溶液培养的方法,研究了NO--N和NH4+-N 2种不同形态氮素对燕麦营养生长、氮代谢及根际pH值的影响.结果表明:在NO--N和NH4+-N两种形态氮素同时存在的营养介质中,燕麦生长明显优于单一供应NH4+-N或NO--N处理,且植株生长量特别是根系生长量随着NO--N在氮源中比例的提高而增加;燕麦吸收NO-N和NH4+-N会对根际pH值产生不同影响,吸收NO--N时,根际pH值逐渐升高,而吸收NH4+-N却使根际pH值有所降低.

关键词: 燕麦, 铵态氮, 硝态氮, 营养生长, 根际pH

Abstract: Solution culture and sand culture were employed to investigate the N on plant growth, nitrogen metabolism as well as rhizosphere pH for oat. The influence of N一N,N03一 results showed:supplied with both N forms, the oats grew obviously better than that with either, and with increase of N/Nratio in cultural zosphere whereas media,oat plants growth especially roots growth was improved; acidity greatly, the pH value of oat rhizosphere was it increased when supplied plants with N03一N. decreased nitrogen forms also affected the oat rhi-when supplied plants with NO3-N.

Key words: Oat, N03一N, N+一N, Vegetative growth, Rhizosphere pH
