摘　　要：针对海藻有机肥的不同施肥方式和不同浓度对草莓叶绿素含量和可溶性固形物含量的影响进行了研究。结果表明,施加浓度适宜的海藻有机肥能在一定程度上增加草莓的叶绿素含量和草莓果实可溶性固形物的含量,根灌效果优于叶面喷洒。海藻有机肥的最佳施肥浓度为4 000倍液,在根灌和叶面喷洒2种施肥方式下,草莓的相对叶绿素值和可溶性固形物含量均达到最高,根灌施肥方式下,草莓相对叶绿素值达到了342.052,草莓可溶性固形物含量达到了14.440%;叶面喷洒施肥方式下,草莓相对叶绿素值达到了332.078,草莓可溶性固形物含量达到了13.744%。The effects of different fertilization methods and different concentrations of seaweed organic fertilizer on the content of chlorophyll and soluble solids of strawberry were studied.The results showed that the application of suitable seaweed organic fertilizer could increase the chlorophyll content and soluble solids content of strawberry fruit,and the root irrigation effect was better than foliage spraying.The optimum fertilization concentration of seaweed organic fertilizer was 4 000 times,and the relative chlorophyll value and soluble solid content of strawberry were the highest under root and foliage spraying.The highest chlorophyll value reached 342.052,the content of soluble solids in strawberry reached 14.440%.The relative chlorophyll content of strawberry was 332.078,and the content of soluble solids in strawberry reached 13.744%.
