| 摘 要： | 以黄瓜种子和幼苗为 试材，研究了栽培1 a、栽培2 a 和栽培3 a 的有机生态型无土栽培基质
的特性和基质浸提液对种子萌发及 幼苗生长的影响。结果表明：栽培3 a 较栽培1 a 的基质的 容重、持水
孔隙度、pH 值、EC 值都极显著增大，基质总孔 隙度和通气孔隙度都极显著降低；栽培3 a 后的基质浸提
液处理黄瓜种子和幼苗，种子发芽率、发芽势、发芽指数和活力指数较对照极显著降低，幼苗主根长、胚
轴长、侧根数、上胚轴粗和下胚轴粗较对照极显著降低；幼苗株高、地上部鲜质量、地上部干质量较对照
极显著降低；幼苗地下部鲜质量和干质量较对照极显著增加；幼苗叶片的光合速率和水分利用率较对照极
显著降低；叶片气孔导度、胞间CO2 浓度和蒸腾速率较对照极显著增大；幼苗根冠比、G 值、叶绿素a 含量、
叶绿素b 含量、叶绿素（a+b）含量和叶绿素a/b 的值较栽培1 a 的基质浸提液处理极显著降低。因此，栽
培3 a 后，基质的特性和内含物不利于黄瓜种子的萌发和幼苗生长。

| Abstract: | Taking cucumber（Cucumis sativus L.） seeds and seedlings as test materials，this
paper studies the characteristics of organic ecological soilless cultivation substrate of cultivation 1
year，cultivation 2 years and cultivation 3 years and effect of substrate extract on seed germination and
seedling growth. The results showed that the dry density，pore water，pH and EC values of cultivation
3 years substrate were increased very significantly compared with that of cultivation 1 year．While the
total porosity and pore of cultivation 3 years substrate were decreased very significantly compared with
cultivation 1 year. After treating cucumber seeds and seedlings with cultivation 3 years substrate extract，
their germination rate，sprout potential，germination index and vigor index were decreased very
significantly compared with that of the CK; and the vertical roots length，hypocotyl radicel length，lat-eral root number，epicotyls and hypocotyl width were also decreased very significantly compared with
that of the CK．The seedling plant height，overground fresh weight and dry weight were decreased very
significantly compared with that of the CK；while the fresh weight and dry weight of underground seedlings
were increased very significantly compared with that of the CK. The leaf photosynthetic rate and
water use efficiency of seedlings were decreased very significantly compared with that of the CK．The
leaf stomatal conductance，intercellular CO2 concentration and transpiration rate of seedlings were increased
very significantly compared with that of the CK. The seedling root-shoot ratio，G value，Chlorophyll
a content，Chlorophyll b content，Chlorophyll（a + b） contents and Chlorophyll a/b value were
decreased significantly compared with that of cultivation 1 year substrate extract treatment．Therefore，
after 3 years’cultivation，the substrate characteristics and contents are not favorable fo r cucumber seed
germination and seedling growth． |
