摘要:
以‘绿蝶’生菜为试材，采用营养块育苗、岩棉块育苗、泡沫块育苗和漂浮育苗等营养液育苗方式进行育苗，通过测定生菜幼苗的叶片形态、根系形态、干鲜质量和壮苗指数等指标，分析比较不同育苗方式的育苗效果，结合可操作性和投入成本，以期筛选出适合生菜的育苗方式，为生菜优质种苗的生产提供参考依据。结果表明：营养块育苗和漂浮育苗方式下生菜育苗效果显著优于其它育苗方式，但漂浮育苗受基质理化性质影响较大，具体表现为T1（营养块）和T6（椰糠∶草炭=7∶3）处理生菜幼苗的茎粗、干鲜质量和壮苗指数等指标均显著高于其它处理，壮苗指数较T3（普通海绵块）处理分别增加了215%和251%；但从实际操作难易程度和投入成本考虑，漂浮育苗比营养块育苗操作简单，且投入成本低，是适合生菜营养液育苗的方式，建议基质配比选用椰糠∶草炭=7∶3为宜。
Abstract:
Taking lettuce ‘Green Butterfly’ as the test material,seedling raising methods including nutrient block seedling raising,rock wool seedling raising,foamed seedling raising and floating seedling raising were used to raise seedlings.The leaf morphology,root morphology,dry and fresh weight and strong seedling index of lettuce were measured,the seedling raising effects of different seedling raising methods were analyzed and compared,combined with operability and input cost,in order to screen the seedling raising methods suitable for lettuce,and provide reference for the production of high-quality lettuce seedlings.The results showed that the effect of lettuce seedling raising by nutrient block and floating seedling raising was significantly better than those by other seedling raising methods,but the floating seedling raising was greatly affected by the physical and chemical properties of the substrate.The specific performance was that the stem diameter,dry and fresh weight and strong seedling index of lettuce seedlings in T1 (nutrient block) and T6 (coconut bran∶peat = 7∶3) were significantly higher than those in other treatments.The strong seedling index increased by 215% and 251% respectively compared with T3 (ordinary sponge block);however,considering the actual operation difficulty and input cost,floating seedling raising was simpler than nutrient block seedling raising,and the input cost was lower than others.It was suitable for lettuce nutrient solution seedling raising.It was suggested that the matrix ratio should be coconut bran∶peat = 7∶3.
