牛粪蚯蚓堆肥基质对草莓生长的影响

Substrate formula of cow manure vermicompost and its effects on 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。

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 suhstrate 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 straw- berry fruit in substrate b was 5 - 15 days earlier than that in suhstrate a and substrate c. So the substrate b can be recommen- ded for the factory production of strawberry growth.
