Abstract:: Taking replanted peach seedling as materials，the methods were used to soil testing and measuring the peach seedling growth，the effects of lime nitrogen on the old orchard soil and the replanted peach seedling growth were studied.The results showed that lime nitrogen could decrease the number of bacteria and fungi，but could increase the number of actinomycetes.Lime nitrogen 60 kg/667m2 could significantly increase the number of actinomycetes.The content of total N was increased the most obviously under the treatments of lime nitrogen 60 kg/667m2 and 20 kg/667m2.Lime nitrogen 60 kg/667m2 could increase the content of organic matter the most obviously.The trunks and branches grew the best under the treatment of lime nitrogen 40 kg/667m2 and soybean cake fertilizer 100 kg/667m2，which was advised to be adopted firstly.
