14TSB_ATC_IR: Use of AMF and PGPR in soil-less substrate strawberry production to increase resource use efficiency and fruit quality

这项建议的重点是提高草莓产量，确保草莓生产的水果供应。为了避免土传疾病，近40%的草莓生产(价值约90m GB)种植在无土栽培的保护地上，那里的养分和水分根据作物需求得到了更好的控制。这项提案涉及有效利用这种资源，对这种资源的管理被认为是提供可持续集约农业的关键驱动因素之一。最近的证据表明，在标准施肥的基质生产体系下，丛枝菌根真菌(AMF)可以增加草莓的产量。本研究旨在研究AMF和PGPR(植物生长促进根际细菌)产品在商业基质中的应用是否会提高资源利用效率、果实品质和不同品种组合对白粉病的耐受性。

This proposal focuses on increasing the yield and ensuring fruit supply from strawberry production. To avoid soil borne diseases, nearly 40% of strawberry production (ca. £90M in values) is grown in soil-less substrate under protection where nutrients and water are better controlled according to the crop requirement. This proposal addresses the efficient use of such resources, the management of which is recognised as one key driver in the delivery of sustainable intensive agriculture. Recent evidence suggests that under a substrate production system with standard fertigation, arbuscular mycorrhizal fungi (AMF) can increase strawberry yield. The present proposal investigates whether application of AMF and PGPR (plant growth promoting rhizobacteria) products in commercial substrates will result in increased resource use efficiency, fruit quality, and tolerance to powdery mildew over different combinations of cultivars.
