Abstract: In order to explore the ease of young apple of continuous cropping obstacles, increase the utilization rate of cultivated land and improve the orchard yield in 2009-2011, the author planted apple seedlings in Mouping, Zhaouuan (2 points), Qixia and Mengyin 5 continuous cropping orchards, combined with comprehensive prevention and control technology system of apple continuous cropping. The result showed that: the trees growth potential of continuous cropping soil ground processed with active zymotic fluid was increased. In these orchards, the number of the middle branches, the short branches, the roughness of branches, the height and ground diameter of trees, the length of new tip and chlorophyll content increased by average 105.45%, 35.75% , 35.92% , 17.65% , 23.66% , 24.96% and 9.16% . So it proved that active zymotic fluid processing continuous cropping soil could obviously reduce the continuous cropping obstacle on apple sapling.
