蘑菇渣和园林废物堆肥复配基质在黄瓜育苗上的应用效果

Effect of Reproducing Compound Substrate for Cucumber Seedling by Mushroom Residue and Garden Waste Compost

以腐熟的蘑菇渣堆肥、园林修剪废物堆肥、草炭、蛭石为原料,通过将蘑菇渣堆肥与园林废物堆肥以不同比例替代草炭后对复配基质的理化特性及普通白菜生长的影响筛选出适宜的配方,并以草炭:蛭石=7V:3V为对照,探讨该配方对黄瓜幼苗生长指标的影响。结果表明,蘑菇渣堆肥:园林废物堆肥:草炭:蛭石=3V:4V:7V:6V为最佳基质配方;受EC值过高的影响,蘑菇渣堆肥和园林废物堆肥替代草炭最大比例不宜超过40%;所获配方基质培育出的黄瓜幼苗株高、茎粗、干物质积累和壮苗指数等指标均显著优于对照。

The spent mushroom compost(MC)and the garden wastes compost(YC)were evaluated as components of substrates in partial substitution of peat for seedlings production.Compost-based substrates,containing different percentage of these 2 composts,were analyzed to find their physicochemical parameter and effect on the growth of Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee,so as to screen out an optimal formula.Then its effects on cucumber(Cucumis sativus L.)seedling quality were investigated comparing with the control(a commercial substrates).The results showed that the substrate's composition of MC:YC:peat:vermiculite=3 V:4 V:7 V:6 V was the optimal formula.The percentage of the MC and YC in compost-based substrates should not exceed 40 %,due to the high EC value.The plant height,stem diameter,dry matter accumulation and seedling index and other indicators of cucumber seedling cultivated on this formula substrate were significantly excelled that of the control treatment.
