| 摘 要： | 本文研究了番茄育苗期养分吸收特性及硼素对番茄幼苗吸收养分的影响。结果表明:番茄育苗期养分吸收量为K>N、P、Ca、Mg。随着苗龄增长,对磷素需求量增加幅度最大。5叶～7叶期的养分吸收量为育苗期吸收总量的60%左右。除NO_3—N外,硼素对番茄苗期P、K、Ca、Mg吸收均有抑制作用,但这种抑制作用主要在3叶期以前;5叶期以后,番茄对硼的耐受能力增强。

| Abstract: | The amount and proportion of nutrients absorbed by tomato at seedlingstage were in the order of K>NO_3--N>Ca>P>Mg. The proportion of Pabsorbed by tomato after three leaf stage increased remarkably, but that ofK decreased. The tomato was comparatively sensitive to Boron before three leaf stage,and the absorption of nutritive elements was inhibited with the increase inB concentration The endurance to Boron raised after five leaf stage |
