Abstract: Using the experimental method of plug-seedling with basic material in intelligent solar greenhouse,the growth characteristics of Rumex Hanus and the influence of seedling growth on different site conditions were analyzed. The results showed that the average value of emergence rate was 95.14±4.86%. Site conditions had significant effects on the emergence rate, plant height, maximum length of leaf and maximum width of leaf.Better site conditions resulted in faster growth. The relationship between seedling height maximum length of leaf,maximum width of leaf and seedling time was found, and the correlation was good. Seedling height, maximum length of leaf and maximum width of leaf had significant negative correlation with site conditions at the early stage of seedling cultivation, seedling height had no significant correlation with site conditions at the middle and late stage of seedling cultivation, maximum length of leaf and maximum width of leaf had no significant correlation with site conditions at the late stage of seedling cultivation. Therefore, the position of the plug can be exchanged in the early and middle stage of seedling cultivation to ensure uniform growth of seedlings.
