Use of arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria in soil-less substrate strawberry production to increase resource use efficiency and fruit quality

本方案侧重于提高基质草莓生产的产量和保证果实供应。为避免土传病害的发生，近40%的草莓种植在无土保护基质上，根据作物的需要，更好地控制养分和水分。本提案将开发新的生物制品（丛枝菌根真菌- AMF和促进植物生长的根瘤菌- PGPR）来修饰底物，以提高资源利用效率，作为实现可持续集约化农业的关键驱动因素之一。本研究旨在探讨AMF和PGPR产品在不同品种和基质类型组合下，是否会提高资源利用效率、果实品质和对白粉病的耐受性。

This proposal focuses on increasing the yield and ensuring fruit supply from substrate strawberry production. To avoid soil borne diseases, nearly 40% of strawberry production is grown in soil-less substrate under protection where nutrient and water are better controlled according to the crop requirement. This proposal will develop new biological products (arbuscular mycorrhizal fungi – AMF, and plant growth promoting rhizobacteria – PGPR) to amend the substrate in order to improve resource use efficiecny, as one of key drivers in the delivery of sustainable intensive agriculture. The present proposal investigates whether application of AMF and PGPR products in commercial substrates will result in increased resource use efficiency, fruit quality, and tolerance to powdery mildew over different combinations of cultivars and substrate types.
