摘要: 在草炭∶珍珠岩(2∶1)体积比的基质穴盘育苗基础上, 通过测定各个处理的番茄(Lycopersicon esculentum Mill.)成苗株高、茎粗、叶片数、地上部干重、地下部干重, 计算出根冠比和壮苗指数, 比较了叶面喷施不同肥料对番茄幼苗生长的影响。结果表明, 处理5的根冠比和壮苗指数均显著高于其他大部分处理, 其植株的株高、茎粗、叶片数、地上部和地下部干重指标均高于多数处理。综合认为, 确定处理5以尿素0.2%、磷酸二氢钾0.1%的组合, 按照出苗后间隔15 d叶面喷施1次、连喷3次的方法最优, 可以在生产实践中应用。

Abstract: The effects of foliar fertilizer with different contents on the seedling growth of tomato(Lycopersicon esculentum Mill.) seedlings were studied on the basis of peat and perlite(volume ratio 2∶1) in plug seedling culture. The results showed that the root-shoot ratio and seedling index of treatment 5 were significantly higher than those of the other 8 treatments, while the indexes including seedling plant height, diameter, leaf number, aboveground and underground dry weight are not lower than other treatments. Comprehensively, it was suggested that the treatment 5 including 0.2% urea and 0.1% potassium dihydrogen phosphate foliage spraying 15 d after seedling emergence was the best treatment and could be applied in the production practice.

Key words: tomato(Lycopersicon esculentum Mill.), plug seedling, substrate, fertilization, growth
