蚯蚓堆肥（VC）被认为可以改善土壤质量和植物产量。然而，VC对草莓生长和品质的影响及其机理尚不清楚。本研究旨在探讨VC对草莓形态生理指标和土壤微生物特性的影响，并分析VC对草莓生长发育的潜在影响机制。在日光温室条件下，采用随机设计盆栽试验。6种不同VC与土壤体积比的处理：100%土壤（对照，CK）；10% VC + 90%土壤（VC10）；20% VC + 80%土壤（VC20）；30% VC + 70%土壤（VC30）；40% VC + 60%土壤（VC40）；50% VC + 50%土壤（VC50）。在本研究中，VC不仅提高了生物量、株高和叶面积等生长性状，而且提高了果实产量、平均果实重以及可溶性糖和维生素c含量。其中，叶绿素含量和净光合速率在白果期显著增加。此外，添加20%和30% VC可显著提高丙二醛含量，降低丙二醛含量，提高超氧化物歧化酶活性。与对照相比，施用VC对土壤微生物和酶活性、阳离子交换能力和根系活性也有显著改善。总的来说，VC对草莓的生长和品质有积极的影响，这是由于增加了光合速率、自由基清除能力和土壤酶活性。
Vermicompost (VC) is thought to improve soil quality and plant yield. However, the effect and mechanism of VC on strawberry growth and quality are not well known. The objectives of this study were to investigate the effects of VC on the morphological and physiological indexes of strawberry and on the microbial properties of soil and to analyze the potential mechanisms of VC on the growth and development of strawberry. A pot experiment was conducted in a randomized design under solar greenhouse conditions. The treatments were six different volumetric ratios of VC to soil: 100% soil (control, CK); 10% VC + 90% soil (VC10); 20% VC + 80% soil (VC20); 30% VC + 70% soil (VC30); 40% VC + 60% soil (VC40); 50% VC + 50% soil (VC50). In this study, VC not only increased growth attributes such as biomass production, plant height and leaf area but also improved fruit yield, mean fruit weight, and the contents of soluble sugar and vitamin C. Notably, chlorophyll content and net photosynthetic rate increased significantly at the white fruit stage. Additionally, 20% and 30% VC addition dramatically improved superoxide dismutase activity and reduced malondialdehyde content. We also found significant improvements in soil microbial and enzyme activity, cation exchange capacity and root activity with the application of VC compared with the control. Overall, VC had a positive effect on strawberry growth and quality, which was attributed to increases in photosynthesis rate, free radical scavenging, and soil enzymatic activity.
