Strawberry cultivation requires strategies that maintain or improve its yield within a scheme in which reducing fertilizers and other chemical products can make its consumption safer and more environmentally friendly. This study aims to evaluate the effect of and on strawberry growth, yield, and fruit quality. and were inoculated and co-inoculated under three fertilization levels of 225-100-250, 112-50-125, and 0-0-0 kg∙ha of N, PO and KO. Vegetative growth was evaluated in plant height (cm), leaf area (cm), aerial fresh weight (g), aerial dry weight (g), and plant coverage (%) variables. Fruit quality parameters such as total acidity (g∙100 mL), soluble solids (Brix°), and firmness (kg) were also determined, as well as the number of fruits per m and yield (t∙ha). The results showed that the pre-treatment of root immersion in a nutrient solution with and the fractionation of 6 L inoculation per plant at a concentration of 10 CFU∙mL, in combination with 225-100-250 kg∙ha of N, PO and KO, achieved the highest accumulation of dry matter (12.9 ± 1.9 g∙plant), the highest number of fruits (28.2 ± 4.5 fruits∙m), and the highest yield (7.2 ± 1.4 t∙ha). In addition, this treatment increased the soluble sugar content by 34.78% and fruit firmness by 26.54% compared to the control without inoculation. This study highlights the synergistic effect of mineral nutrition and microbial inoculation with in increasing strawberry yield and fruit quality.
草莓种植需要一些策略，以便在减少肥料和其他化学产品用量从而使草莓消费更安全、更环保的方案中维持或提高其产量。本研究旨在评估[具体物质1]和[具体物质2]对草莓生长、产量和果实品质的影响。在施氮量、五氧化二磷量和氧化钾量分别为225 - 100 - 250千克/公顷、112 - 50 - 125千克/公顷和0 - 0 - 0千克/公顷的三种施肥水平下进行了[具体物质1]接种、[具体物质2]接种以及二者共接种。通过株高（厘米）、叶面积（平方厘米）、地上部鲜重（克）、地上部干重（克）和植株覆盖率（%）等变量评估营养生长情况。还测定了果实品质参数，如总酸度（克/100毫升）、可溶性固形物（°Brix）和硬度（千克），以及每平方米果实数量和产量（吨/公顷）。结果表明，将根系浸入含有[具体物质1]的营养液中进行预处理，并以每株6升、浓度为10⁶CFU/毫升的量分株接种[具体物质2]，再结合225 - 100 - 250千克/公顷的氮、五氧化二磷和氧化钾，实现了最高的干物质积累（12.9±1.9克/株）、最高的果实数量（28.2±4.5个/平方米）和最高的产量（7.2±1.4吨/公顷）。此外，与未接种的对照相比，该处理使可溶性糖含量提高了34.78%，果实硬度提高了26.54%。本研究突出了矿质营养与[具体物质2]微生物接种在提高草莓产量和果实品质方面的协同效应。
