摘　　要：以核桃木腐熟菌渣为试材,采用复配基质草炭∶蛭石∶珍珠岩=1∶1∶1作为对照,分别以25%、50%、75%、100%比例的核桃木腐熟菌渣与园土进行复配并进行黄瓜育苗,研究了不同配方基质对黄瓜幼苗生长的影响,以期为核桃木腐熟菌渣作为育苗基质材料提供参考依据。结果表明:核桃木腐熟菌渣能够提高园土的容重、总孔隙度、气水比,持水孔隙度呈递减趋势,通气孔隙度呈上升趋势;pH随着菌渣添加比例的增加而降低,EC值、有机质含量均随着菌渣比例增加而提高;在园土中添加50%腐熟菌渣的育苗基质的黄瓜植株的株高、茎粗、鲜质量和干质量显著提高,叶绿素相对含量及叶面积显著增加;主成分分析结果表明,园土中添加50%比例的腐熟菌渣的基质综合性能越好。综上,核桃木腐熟菌渣可作为复配材料用于黄瓜育苗基质生产。Walnut wood decayed mushroom substrate was used as the test material,and the compound substrate grass charcoal∶vermiculite∶perlite=1∶1∶1was used as the control,and the proportion of walnut wood chips spent mushroom substrate with garden soil was compounded and cucumber seedlings were grown at the ratios of 25%,50%,75%and 100%,respectively.The effects of different formulations of substrates on the growth of cucumber seedlings were investigated,in order to provide reference for the use of walnut wood-rotting mushroom residues as seedling nursery substrate materials.The results showed that walnut wood rotting fungus residue could increase the bulk density,total porosity,air-water ratio and water-holding porosity of garden soil,and the porosity of ventilation showed an increasing trend.pH decreased with the increase of the proportion of bacterial residue,and the contents of EC value,organic matter content,increased with the increase of the proportion of bacterial residue.The plant height,stem thickness,fresh weight and dry weight of cucumber plants with 50%decay residue were added to the garden soil,and the chlorophyll content and leaf area were significantly increased.In summary,walnut wood rotten bacteria residue could be used as a compound material for cucumber seedling substrate production.
