摘要
为了筛选出适宜张家口山区蔬菜育苗的基质种类,以当地农业有机废弃物玉米秸秆、菇料、酒糟和牛粪为主要原料,按照不同体积比复配成4种育苗基质,以草炭50%+珍珠岩25%+蛭石25%复配成的基质为对照(CK),研究了不同育苗基质对黄瓜出苗率、生长势指标(株高、茎粗、叶面积、植株鲜重、植株干重)和壮苗指标(根鲜重、G值、壮苗指数)的影响。结果表明:在酒糟70%+牛粪15%+蛭石15%复配成的基质上黄瓜幼苗生长效果最好,在菇料70%+牛粪15%+蛭石15%复配成的基质上幼苗生长效果次之,二者指标差异以及与CK指标差异均不显著。在黄瓜育苗中,可用酒糟和菇料替代草炭进行基质复配。
In order to screen out the appropriate matrix species for vegetable seedling in Zhangjiakou mountain areas, the local agricultural organic wastes （ corn stalks, mushroom materials, lees and cow dung） were taken as main materials, four kinds of nursery substrate were confected according to different volume ratio , taking the nursery substrate of peat 50% ＋perlite 25% ＋vermiculite 25% as the comparison （ CK ） to study the effects of different substrates on cucumber seedling emergence, growth potential indicators （ including height, stem diameter, leaf area, plant fresh weight and dry weight） and seedling indicators （ including root fresh weight, G values and seedling index ） .The results showed that cucumber growth in the substrate of lees 70% ＋cow dung 15%＋vermiculite 15% was better than other treatments, and the effect of substrate of mushroom material 70%＋cow dung 15% ＋vermiculite 15% was followed, the differences between two treatments and CK were not significant.Peat could be replaced with lees and mushroom material in cucumber seedlings for application.
