摘　　要：本研究采用盆栽试验法,设置3个磷水平,即P_(2)O_(5)施用量分别为0(P0)、100(P100)、200(P200)mg/kg干基质,以番茄品种东农708为主栽作物,分别与油菜、芝麻菜、芥菜、萝卜、黄瓜、莴苣、小麦、大豆、番茄9种作物伴生,以番茄单株种植为对照,研究磷水平及不同作物伴生对番茄幼苗生长及磷吸收的影响。结果表明,与番茄单株种植相比,P0水平下,不同作物伴生对番茄幼苗株高、茎粗、干鲜重及根系形态均无显著影响,而油菜、莴苣、小麦和大豆伴生对番茄幼苗磷吸收有显著的促进作用;P100水平下,芝麻菜、萝卜、黄瓜、莴苣、小麦、大豆和番茄共7种作物伴生对番茄幼苗生长有显著的抑制作用,且黄瓜伴生对番茄幼苗磷吸收产生显著的抑制作用,仅油菜伴生显著促进番茄幼苗的磷吸收;P200水平下,萝卜和黄瓜伴生对番茄幼苗生长有显著的抑制作用,其余7种作物对番茄幼苗生长无显著影响,所有伴生作物对番茄幼苗磷吸收均无显著影响。In this study,the pot experiment was conducted by setting three phosphorus levels with P_(2)O_(5) application rates of 0(P0),100(P100)and 200(P200)mg/kg in dry substrate,and with tomato variety‘Dongnong 708’as the focal plant.The associated crops were rape,arugula,mustard,radish,cucumber,lettuce,wheat,soybean and tomato,and single plant of tomato was as control.The effects of different phosphorus level and associated crops on growth and phosphorus uptake of tomato seedlings were studied.The results showed that compared with the control,at P0 level,different associated crops had no significant effect on plant height,stem diameter,dry and fresh weights,and root morphology of tomato seedlings,but phosphorus uptake was significantly promoted when accompanying with rape,lettuce,wheat and soybean.At P100 level,a total of seven associated crops,which were arugula,radish,cucumber,lettuce,wheat,soybean and tomato,showed significant inhibiting effects on growth of tomato seedlings,and the significant inhibiting effect on the phosphorus uptake was observed when accompanying with cucumber;the significant promoting effect on phosphorus uptake was only found when accompanying with rape.At P200 level,accompanying with radish and cucumber had significant inhibiting effects on growth of tomato seedlings,while the other seven plants had no significant effect.No significant effect on phosphorus uptake was observed in either of the associated crops.
