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 cucumber was used as the test material and the matured ginger straw, vermiculite and perlite were mixed in different proportions to study the physicochemical properties of the compound matrix and its effects on the chlorophyll content, photosynthetic rate, growth morphology and biomass of cucumber seedlings . The results showed that the physical and chemical properties of ginger straw composite matrix were within a reasonable range of plant growth. The ginger straw composite matrix significantly increased the chlorophyll content and photosynthetic rate of cucumber leaves, increased the plant height, stem diameter and biomass of cucumber Conducive to the growth of cucumber seedlings, of which straw: vermiculite: perlite = 3: 2: 2 the best treatment. Therefore, ginger straw can replace peat as cucumber seedling substrate.
