Abstract: Abstract:In order to improve the yield and quality of peach seedings,The author has carried out the peach seedling and transplanting test,discussed the characteristics, ecological habits of peach of Suqian area, studied the comprehensive technology of seedling density and field management etc. The results showed that sowing and transplanting density to 15 strains per square meter was appropriate,the average diameter of seedlings reach 0.9-1.0cm in the same year;sowing density was negatively associated with seedling biomass;seedling ground diameter was positively related to the plant height, taproot length, lateral root length,root dry weight and number of leaves,There was no significant correlation between seedling ground diameter and root fresh weight,number and position of lateral root.
