| 摘 要： | 采用盆栽方法,研究了磷肥对日光温室番茄苗期生长及生理特性的影响.结果表明:磷肥(P2O5)用量在3.15～4.78g/kg范围内,有利于培育番茄壮苗,其生长与不施磷肥处理差异显著;当磷肥用量超过9.69g/kg时,植株生长受到明显抑制,地上部分干物质积累显著下降,叶片中可溶性糖含量下降,丙二醛含量和相对电导率有所增加.本试验条件下,日光温室番茄苗期磷肥(P2O5)需求阈值为4.78g/kg左右.

| Abstract: | Effects of different phosphorus fertilization application on the growth of tomatoes seeding were studied.The result showed that the phosphorus application(P2O5),ranging from 3.15 to 4.78 g/kg soil,could benefit to stronger tomatoes seeding.Compared with the treatment without applying phosphorus,the differences of growth of tomatoes in other treatments were remarkable.When the phosphorus application exceed 9.69 g/kg soil,photosynthesis rates and the dry weights of shoots declined.The content of soluble sugar in the tomato leaves declined.The growth of tomatoes seeding was restrained.In this study,with increasing phosphorus application,the conductance rates of tomato leaves were increasing,but there were no remarkable changes of the MDA contention in tomato leaves among treatments. |
