摘要
为了探讨以草莓叶片元素为参考得出的施肥配方对草莓果实产量和可溶性固形物含量(SSC)的影响,以草莓品种"圣诞红"为试材,先利用叶片元素分析法测定草莓矿质元素的含量,确定了3种施肥配方(配方1、2、3),进而利用比例注肥泵的水肥一体化系统对温室中栽培的"圣诞红"进行施肥和管理。通过定期检测果实SSC和统计产量来评价配方效果。结果表明:利用配方1、2、3施肥管理的草莓果实在总产量、平均单株产量、平均单株果数和单果质量上都显著高于常规施肥方式下草莓果实的各参数(P<0.05);配方3施肥下,草莓在果实产量、平均单株产量和单果质量上高于配方1和配方2施肥下的果实;配方2施肥下的草莓SSC最高,但与配方1和配方3施肥下的草莓SSC无显著差异。说明草莓种植时更适合满足其自身需求的营养元素供给,以草莓叶片矿质元素分析为依据的施肥配方明显提高了其果实产量和SSC,多组比例注肥泵并联使用保证了其配方肥料的均衡比例和投加的精准度,该方法更具科学和合理性,具有应用推广前景。
To assess the formulated fertilization based on leaf elements on yield and soluble solids content (SSC) of strawberry fruit. Strawberry cultivar 'Ssanta' was used as test material,three kinds of fertilization formulas (FF 1,2, 3) were obtained from leaf element analysis which was used to test the content of mineral elements of strawberry leaves. Combine with proportional injection pump system in water and fertilizer integration, 'Ssanta' was cultured and managed in greenhouse. The effects of the formulas were evaluated by regular testing for fruit SSC,yield and yield components. The results showed that under the fertilization management of FF 1,2,3, total yield,average yield per plant, fruit number per plant and single fruit weight of strawberry were significantly higher than the conventional way (P〈0. 05). The total yield,average yield per plant and single fruit weight were higher when used FF 3 than used FF 1 and FF 2. The SSC under FF 2 was the highest while there was no significant difference with FF 1 and FF 3. The results indicated that strawberry planting fertilization was more suitable to meet their own needs nutrients supply. The formulas of fertilization based on strawberry leaf mineral element analysis was significantly increased the fruit yield and SSC. Multiple sets of proportional injection pump in parallel ensured the balance of the fertilizer proportion and dosing accuracy which had the application prospect of promotion. The method was more scientific and reasonable.
