Abstract：In order to optimize the industrialized seedling technology of fresh waxy corn and screen suitable seedling cultivation substrates,taking Suyunuo 11 and Suyunuo 818 as test varieties,this study analyzed the growth,dry matter accumulation of roots and aboveground,and the root-shoot ratio under Sanyi Nongye substrate(T1),Shouguang Hengxian substrate(T2)and Dahan Wosong substrate(T3).The results showed that different substrates had different effects on the seedlings of fresh waxy corn.Specifically,the Shouguang Hengxian substrate(T2)was superior to other substrates in improving the aboveground growth indexes of both varieties.For instance,the average plant height under T2 was 1.9%and 4.0%higher than that under T1 and T3 treatments,respectively,and the leaf area increased by 4.9%and 11.5%,while the Dahan Wosong substrate(T3)significantly increased root fresh weight by 57.1%and 6.9%,root dry weight by 112.9%and 71.6%,and root-shoot ratio by 123.9%and 96.3%compared to T1 and T2,respectively.Based on these findings,it is recommended to prioritize the Dasen Wosong substrate(T3)in the industrial seedling production of fresh waxy corn.
