牛粪蚯蚓堆肥基质对草莓生长的影响

摘要

In this study,the cow manure vermicompost,peat,perlite,and vermiculite were mixed with different proportions (the volume ratio of vermicompost,peat,perlite,and vermiculite in substrate a,substrate b,substrate c were 0∶4∶1∶1,2∶2∶1∶1,4∶0∶1∶1,separately),to select the best growth substrate for strawberry through the analysis of strawberry growth,yield and quality.The results showed that the substrates were general suitable for strawberry growth.Generally,the soluble sugar content,sugar-acid ratio,soluble solids content,ascorbic acid content,soluble protein content,anthocyanins content of strawberry fruits in substrate b were higher than that in substrate a and substrate c.In addition,the harvesting time of strawberry fruit in substrate b was 5 ~ 15 days earlier than that in substrate a and substrate c.So the substrate b can be recommended for the factory production of strawberry growth.%将奶牛粪蚯蚓堆肥与泥炭、珍珠岩和蛭石按不同体积比例复配成3种草莓生长基质,体积比分别为0∶4∶1∶1(基质a),2∶2∶1∶1(基质b),4∶0∶1∶1(基质c),通过分析草莓的生长情况、果实产量和品质,筛选出适合草莓生长的最佳基质配比.结果表明,复配后生长基质的理化性质优良,适合草莓生长.3种基质中,以基质b效果最佳,综合来看,基质b栽培的草莓果实可溶性糖、糖酸比、可溶性固形物、抗坏血酸、可溶性蛋白和花青素含量均不同程度高于其他两种基质.此外,与基质a和基质c相比,基质b的草莓果实收获期提前了5~15 d.该配方可推荐用于架式草莓工厂化栽培生产.
