草莓基质栽培中营养液应用技术研究对其生长及品质的影响OA

Compared with traditional soil culture,substrate culture can avoid continuous cropping obstacles,reduce pesticide application,and improve yield and quality.This study proposes a nutrient solution formula for soilless substrate cultivation of protected strawberries.The formula fully considers the nutrient element requirements of strawberries at each growth stage,the regulatory effects of each nutrient element,and the synergistic and antagonistic effects among different elements on strawberry growth,addressing the problems of lack of targeting and specificity in nutrient solutions for strawberry soilless cultivation,and thus realizing the improvement of production quality and yield of strawberries under soilless cultivation.the nutrient solution formula proposed in this study is conducive to the robust development of strawberry seedlings during the seedling stage,promotes plant photosynthesis and chlorophyll synthesis,enhances the stress resistance of strawberries during the fruiting period,and improves fruit quality.In addition,under the same cultivation environment and substrate conditions,reasonable fertilization and irrigation levels play a decisive role in improving strawberry yield.This study can provide a theoretical basis and technical support for the establishment of an elevated substrate cultivation system for greenhouse strawberries.
