摘要：

为评估凹凸棒石生物肥料对连作草莓生长和土壤环境的调控效果，本研究以‘红颜’草莓为试验材料，设置常规施肥(CK)、增施商品有机肥(T3)为对照，比较施用凹凸棒石复合微生物肥(T1)和凹凸棒石生物有机肥(T2)的处理效果。结果表明，在连作草莓生长方面，与CK相比，T1、T2处理显著提高了连作草莓产量，增产幅度分别增产15.56%、12.71%；果实品质也得到显著提升，其中可溶性固形物分别提高43.00%、41.17%，可溶性糖分别增加31.40%、26.32%。在土壤环境改善方面，T1、T2处理改善了土壤环境，显著提高了土壤有机质含量和蔗糖酶活性。微生物群落分析显示，T1处理的细菌Chao指数和Shannon指数分别比CK处理提高1.18倍、1.03倍(P<0.01)；T2处理的真菌Chao指数和Shannon指数分别比CK处理提高1.72倍、1.14倍(P<0.05)。此外，2种处理均能显著提高球囊菌门丰度，降低担子菌门丰度(P<0.05)，并在属水平上增加苯基杆菌属、Linnemannia sp.和金孢属等有益微生物的种群丰度，降低病原菌Dactylonectria sp.的丰度(P<0.05)。综上，施用凹凸棒石生物肥料可有效消减草莓连作障碍。

Abstract:

This study aims to evaluate the regulatory effects of attapulgite-based biofertilizers on the growth of continuous cropping strawberry plants and soil environment. Using the strawberry cultivar ‘Hongyan’ as the experimental material, treatments were designed as follows: conventional fertilization (CK) and supplemental commercial organic fertilizer (T3) as controls, compared with supplemental attapulgite composite microbial fertilizer (T1) and attapulgite bio-organic fertilizer (T2). The results demonstrated that, compared to CK, T1 and T2 treatments significantly increased the yield of continuous cropping strawberries by 15.56% and 12.71%, respectively. Fruit quality was also improved, with soluble solids content elevated by 43.00% and 41.17%, and soluble sugar content increased by 31.40% and 26.32%, respectively. Additionally, both treatments markedly enhanced soil organic matter and invertase activity. Compared to CK, microbial community analysis revealed that T1 increased bacterial Chao and Shannon indices by 1.18-fold and 1.03-fold (P<0.01), while T2 elevated fungal Chao and Shannon indices by 1.72-fold and 1.14-fold (P<0.05). Furthermore, both treatments significantly increased the relative abundance of Glomeromycota while reducing Basidiomycota abundance (P<0.05). At the genus level, beneficial microorganisms such as Phenylobacterium sp., Linnemannia sp., and Chrysosporium sp. were enriched, whereas the pathogenic fungus Dactylonectria sp. was suppressed (P<0.05). These findings indicate that attapulgite-based biofertilizers effectively mitigate strawberry continuous cropping obstacles.
