不同配比菇渣基质对草莓植株营养生长的影响

Effect of Different Proportion of Mushroom Residue Substrates on Vegetative Growth of Strawberry

为探索菇渣基质利用的可行性,以不同比例菇渣直接替代东北泥炭配制基质作处理,并以进口商品基质为对照进行草莓栽培试验,研究了复配后不同处理基质的理化性质及栽培草莓后对植株营养生长的影响。结果表明,随着菇渣含量的增加,基质的EC值、pH值、容重增加,孔隙度、大小孔隙比减小,栽培草莓后成活率、株高、株径、叶面积均减小。未经处理的菇渣可以部分替代泥炭来栽培草莓,但替代量有限,菇渣作为基质使用时首先须解决EC值过高的问题。

In order to explore the feasibility of using mushroom residue, the northeast peat substrate was replaced directly with different proportion of mushroom residue, strawberry cultivation test was conducted with imports matrix as control, and physicochemical properties and effects of matrix compound on vegetative growth of strawberry were studied. The results showed that the EC value, pH value and bulk density of the substrate increased with the increase of the content of the mushroom residue, the porosity and the pore ratio decreased, and the survival rate, plant height, plant diameter and leaf area were decreased. Untreated mushroom residue could partly replace peat to cultivate strawberry, but the amount of substitution was limited. When the mushroom residue was used as matrix, the problem of high EC value must be solved first.
