【摘要】In order to provide a guide for apple tree planting in Hebei Luanping,the 3-yearold'Guoguang'apple seedlings were used as materials to study the effects of different planting dates on survival rate and tree growth.The results showed that when the seedlings were planted on April 8th,the survival rate and the number of long shoots on the lower small main branches were 92.67％ and 9.26 respectively,which were very significantly higher than those of seedlings planted on April 15th and April 22nd.The average shoot length of seedlings on April 8th was 39.93 cm,which was significantly higher than those of seedlings planted on April 15th and April 22nd.The number of long shoots of the single tree was 13.73,which was significantly higher than those of seedlings planted on April 22nd.When the trees were planted on April 15th,the survival rate,bud sprout rate on the lower small main branches,and the number of long shoots on the lower small main branches were 75.67％,39.71％ and 7.58 respectively,which were very significantly higher than those of trees planted on April 22nd.The number of medium shoots of one tree was 14.95,which was significantly higher than those of seedlings planted on April 22nd.There were no
