不同栽培基质对高架草莓生长及品质的影响

Effects of Different Substrates on Growth and Quality of Elevated Strawberry

  • 摘要: 为筛选适宜高架草莓栽培的基质,促进资源的循环利用,以草莓品种隋珠为材料,研究了4种不同基质对高架草莓生长及果实品质的影响。结果表明:草莓移栽40d,基质CT(草炭∶蛭石∶珍珠岩=2∶1∶1)、JZ(草炭∶蛭石∶珍珠岩∶菌渣=5∶2∶2∶1)可显著提高草莓根系活力、叶绿素含量、最大单叶面积、株高及茎粗,与CK(草炭∶珍珠岩∶蛭石=3∶1∶1)相比,草莓单株产量分别增加了17.1%和11.6%。不同基质处理对高架草莓果实品质影响较小,CT处理可溶性固形物含量最高,较CK高4.4%,JZ处理的草莓VC含量、糖酸比最大,较CK分别高2.0%和3.4%。JZ处理和CT处理在高架草莓生长、果品品质和增产上效果均较好,同时降低了成本,可以在生产中推广使用。

     

    Abstract: In order to select the suitable substrate for strawberry elevated cultivation and promote the recycling of resources,the effects of four different substrates on the growth and fruit quality of strawberry were studied.The results showed that after 40 days of strawberry transplanting,matrix CT(peat∶vermiculite∶perlite=2∶1∶1)and JZ(peat∶vermiculite∶perlite∶mushroom residue=5∶2∶2∶1)could significantly improve strawberry root activity,chlorophyll content,maximum single leaf area,plant height and stem diameter.Compared with CK(peat∶vermiculite∶vermiculite=3∶1∶1),strawberry yield increased by 17.1% and 11.6% respectively.The content of soluble solids in CT treatment was the highest,which was 4.4% higher than that of CK.The VC content and sugar acid ratio in JZ treatment were the highest,which were 2.0%and 3.4% higher than that of CK,respectively.JZ treatment and CT treatment had better effect on the growth,fruit quality and yield increase of elevated strawberry,at the same time,it reduced the cost,and could be widely used in production.
