Effects of silicon and trace elements on the growth of lily

摘要: 在施用氮磷钾肥基础上配施硅肥、硼肥等有益元素和微量元素,探讨其对百合生长的影响.结果表明:增施硅肥或微肥,特别是硅肥能显著促进百合的生长,株高增加2~8 cm、茎秆增粗1.98~2.0 cm、花朵数增加8.3%~23.6%、花苞增大2.1%~4.0%,同时可提高百合植株的氮、磷、钾及叶绿素含量,且随着硅肥用量的增加(≤40 kg·hm-2),以上各指标也随之增加.Abstract: Effects of silicon,boron and other trace elements on the physiological properties of lily were studied.The results showed that silica and trace elements,silicon in particular,increased the lily’s plant height by 2-8 cm,stem diameter by 1.98-2.05 cm,number of flowers by 8.3%-23.6%,and bud size by 2.1%-4.0%.And at the same time,they improved the N,P,K and chlorophyll contents in the plant.As the silica application increased(≤450 kg·hm-2),the above indexes increased correspondingly.
