为了揭示根区温度对烤烟烟碱积累的影响机制,通过盆栽试验研究了根区温度(10,18,26和35℃)与氮素形态(100%NH_4~+-N,50%NH_4~+-N+50%NO_3~--N和100%NO_3~--N)互作对烤烟生物量和烟碱积累的影响。结果表明:适当提高根区温度可增加烟株生物量,NO_3~--N比NH_4~+-N更有利于烟株的生长。当根区温度为35℃时,供应100%NH_4~+-N和50%NH_4~+-N+50%NO_3~--N的烟株生长受到抑制,而供应100%NO_3~--N的烟株生长旺盛。氮素形态对烟株生物量的影响大于根区温度。烟株的烟碱积累量在根区温度为18℃时达到最大,供应100%NO_3~--N的烟株烟碱积累量是供应100%NH_4~+-N烟株的1.64倍,施用NO_3~--N有利于烟碱的合成。当...

In order to reveal the effects of rhizosphere temperature on the nicotine accumulation in flue-cured tobacco, the interaction effects of rhizosphere temperature (10, 18, 26, 35℃) and nitrogen form (100% NH4+-N, 50% NH4+-N+50% NO3--N, 100% NO3--N) on the accumulation of biomass and nicotine in flue-cured tobacco were studied with a pot experiment. The results showed that the biomass in tobacco plants was increased by rising rhizosphere temperature properly; NO3--N was more beneficial to plant growth than NH4+-N. At the rhizosphere temperature o...
