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。 In this paper, the nutrient absorption characteristics of tomato seedling and the effect of boron on the nutrient uptake of tomato seedlings were studied. The results showed that the nutrient uptake of tomato seedling was K> N, P, Ca and Mg. As seedling growth, the largest increase in demand for phosphorus. 5 leaf ~ 7 leaf nutrient uptake for seedling absorption of about 60% of the total. Boron not only inhibited the absorption of P, K, Ca and Mg in tomato seedling except NO_3-N, but it was mainly inhibited before the third leaf stage. After the fifth leaf stage, the tomato tolerance to boron increased.
