摘要
以腐熟菇渣、牛粪为主要原料,研究4种不同配方基质对黄瓜幼苗叶片生理特性和根系活力的影响。结果表明,牛粪、菇渣、草炭、蛭石按体积比2∶2∶4∶2配制的基质中,黄瓜幼苗叶片净光合速率最高,可溶性蛋白和可溶性糖含量显著高于其余处理,叶绿素含量、比叶重、根系活力与传统育苗基质(草炭与蛭石体积比为6.7∶3.3)无显著差异,可代替传统基质用于黄瓜育苗。
With mushroom compost and cow dung used as main materials,the experiment is conducted to study effects of four different substrates formula on physiological characteristics of leaves and root activity in cucumber seedling. The result shows that the net photosynthetic rate of leaves reached the highest value in the substrate C（cow dung： spent mushroom compost： peat substrate： vermiculite =2 ∶ 2 ∶ 4 ∶ 2,v/v）. The levels of soluble protein and soluble sugar in substrate C are significantly higher than other treatments. The chlorophyll content,specific leaf weight and root activity of plants cultivated with substrate C had no significant difference with those cultivated with CK. Thus,the substrate C can be used to raise cucumber seedlings instead of CK.
