苹果渣基质在烟台地黄瓜育苗中的应用

Effects of Apple Pomace on Yantai Ground Cucumber Seedling

[目的]研究了苹果渣基质在黄瓜育苗中的应用效果。[方法]以苹果渣为材料,与草炭、珍珠岩按不同比例配制成5种基质,研究它们的理化性质及其对黄瓜营养钵育苗生长和生理指标的影响。[结果]采用苹果渣∶草炭∶珍珠岩1∶4∶1(体积比)的基质配方,黄瓜育苗效果较好,幼苗出苗率、壮苗指数优于对照(基质草炭∶珍珠岩5∶1)。[结论]在黄瓜育苗中用20%～50%的苹果渣替代草炭有利于黄瓜幼苗的生长。

[Objective]The research aimed to study the effects of apple pomace on the cucumber seedling.[Method]Apple pomace was used as nursing media for cucumber seedlings by mixing with peat and perlite at different volume ratios.The physical and chemical properties of the media and their effects on growth and physiological indices of cucumber seedlings were investigated.[Result] The effects of the substrate medium of apple pomace∶peat∶perlite 1∶4∶1 was better for cucumber seedlings with higher emergence rate and better vigorous seedling index compared to the check of peat：perlite 5∶1.[Conclusion]Apple pomace can replace peat,and the replacement rate 20%-50% was the most appropriate condition for the growth of the cucumber seedling.
