摘　　要：2012年春定植2种砧木GF677和青州蜜分别嫁接3个品种春元、北京52、春艳的苗木,进行桃砧木抗重茬能力试验。经10年的观察比较发现,砧木GF677组合与砧木青州蜜组合比较,具有明显的生长旺盛的优点,树高、冠径大,总枝量多;在枝类构成方面,砧木GF677组合的中短枝/长枝比率小,长枝多。这表明砧木GF677组合受重茬地影响小,抗重茬能力强。但砧木GF677组合树的品种/砧木干径比小,存在“大脚”现象重,表明嫁接亲和性较差,但与砧木青州蜜组合的差异不显著。In the spring of 2012,two rootstocks,GF677 and Qingzhoumi,were planted and grafted with three varieties,Chunyuan,Beijing 52,and Chunyan respectively,to conduct a trial on the ability of peach rootstocks to resistance to continuous cropping.Through the comparative experiment,it was found that GF677 had obvious advantages in the growth of trees.The main performance was that the height,crown diameter and total branch amount of GF677 were all higher than Qingzhoumi,but the ratio of medium and short branches to long branches was lower.The grafted variety of GF677 had strong growth and was least affected by continuous cropping.GF677 grafted tree species/rootstock ratio was lower,and there was a“big foot phenomenon”.After grafting,it had weak affinity and stability,but not significant difference to Qingzhoumi.
