生姜秸秆复配基质在黄瓜育苗上的应用

Application of Mixed Substrate of Ginger Straw in Cucumber Seedling

以黄瓜为试材,以腐熟的生姜秸秆、蛭石和珍珠岩按照不同的比例进行复配,研究了复配基质的理化性质及其对黄瓜幼苗叶绿素含量、光合速率、生长形态和生物量的影响。结果表明:生姜秸秆复配基质的理化性质在植株生长的合理范围内,生姜秸秆复配基质显著提高了黄瓜叶片的叶绿素含量和光合速率,提高了黄瓜的株高、茎粗和生物量,有利于黄瓜幼苗生长,其中以秸秆∶蛭石∶珍珠岩=3∶2∶2的处理效果最佳。因此,生姜秸秆可以替代草炭作为黄瓜的育苗基质。

The decomposed ginger straw,vermiculite and perlite were mixed according to different volume ratio.The physical and chemical properties of mixed substrate were measured.The effect of mixed substrate to the chlorophyll content,photosynthetic rate,growth morphology and biomass of the cucumber leaves were studied.The results showed that the physical and chemical properties of the mixed substrate of ginger straw were suitable to plant growth.The chlorophyll content,photosynthetic rate,plant height,stem diameter and biomass were higher than the contrast.T2treatment（ginger straw∶vermiculite∶perlite=3V∶2V∶3V）was the best.Therefore,ginger straw could be replace peat for cucumber seedlings.
