Abstract
[ Objective ] From the perspective of environment protecting the problem in re-cropping of fruit tree was solved through the experiment. [ Method] A pot experiment in the amount of different biological agents and dried chicken manure applied in the soil of root zone and between the tree lines in old orchard was conducted and the effect of the biological agents on the control of re-cropping of apple tree was analyzed.[ Result ] The young apple tree among the different treatments developed much better than that from the re-cropping zone of apple tree root. Among all of treatments, 1.0 kg biological agent was the best one, which indicated the significant differences with other treatments in the plant height, the annual increment of dry matter, the shoot length and width, the leaf area, the leaf weight, the root activity, with the increment of 41.48％, 39.53％, 28.82％, 26.00％, 33.42％, 37.38％, 33.48％, respectively compared with CK. The single-leaf weight and the content of chlorophyll of apple was 18.55％ and 24. 19％ higher than CK,which could effectively improve soil nutrient content. [ Conclusion ] The biological agents had a good effect on the inhibition of the apple tree re-cropping, which could further be applied in production.关键词
